ALMA is exploring key upgrades to enhance its sensitivity, resolution, and imaging capabilities, focusing on transformative advancements that will unlock its full scientific potential. As part of an ongoing ESO ALMA development study aimed at advancing ALMA’s capabilities, the community workshop "Unlocking ALMA’s Potential with Focal Plane Arrays" will take place on September 2 - 4, 2025, at MPIfR, Bonn.

This event will explore the scientific drivers and technological innovations behind focal plane arrays (FPAs) - a breakthrough that could significantly expand ALMA’s field of view and mapping speed. This conference welcomes experts from all fields of astrophysics who are interested in shaping the scientific priorities for the next phase of ALMA, driven by the transformative capabilities enabled by the development of focal plane arrays (FPAs).

Despite playing a central role as the building blocks of cosmic structures, the processes governing star formation and evolution remain among the least understood phenomena in the Universe. Key questions range from what mechanisms drive the transition from diffuse atomic to molecular clouds to form stars and how the evolution of stars shape their environment on both local and on global scales. The aim of the 839 WE-Heraeus-Seminar is to foster collaborative discussions and showcase groundbreaking research in this field.

Highlights will include new observations from high-powered telescopes, along with theoretical and computational results using state-of-the-art simulations. Furthermore, as we enter an era of highly sensitive instrumentation, bringing together communities representing the main pillars of modern astronomy will enable us to address the complexities of star-formation and stellar evolution more effectively. 
This seminar will also honour the life and work of Prof. Dr. Karl M. Menten, our dear friend, esteemed mentor, and wonderful colleague, whose sudden and unexpected passing has left us heartbroken. However, his legacy endures. His contributions over the past forty years have been a driving force and a source of inspiration for countless researchers in the field of Astornomy and Astrophysics.

We are pleased to announce the RadioNet Technical Dissemination Workshop on new trends in Radio Astronomy instrumentation. These two days of coming together, presenting new ideas and discussing future trends will be held on September, 21st and 22nd 2020 at the Max-Planck-Institute for Radio Astronomy in Bonn (Germany).

This meeting is the last in a series of technical workshops combining several aspects of engineering and operational issues at radio observatories all over Europe and beyond. It provides the unique opportunity to cross border the different communities to see what ‘the others’ are doing and planning and enhance communication between engineers, scientists and operators.

The BONN neutron star workshops aim to bring together observers and  theoreticians to exchange and discuss new ideas related to neutron star  research in a one-day workshop.

The special topic of this workshop is: "Peculiar supernovae and neutron stars".
 

The Atacama Pathfinder Experiment (APEX) 12 m submillimeter telescope has significantly contributed to a wide variety of astronomy science areas, ranging from the discoveries of new molecules to large-scale and deep imaging of the submillimeter sky.

Since 2012, every other year, the Ringberg APEX workshops bring together APEX users and other interested scientists working on a wide range of exciting results covering the Solar System to distant galaxies in the early Universe. APEX2020 aims at presenting new science results and to looking into new science opportunities for the next years.

In the last two years, APEX has been significantly improved by upgrades of the antenna itself as well as by the commissioning of new instruments, including new large cameras for wide-field continuum imaging and new heterodyne instruments highly complementary to ALMA.

While ALMA operation is in full swing, APEX is strengthening its role not only as a pathfinder for studying large source samples and probing larger spatial scales to prepare detailed high angular resolution ALMA follow ups, but also as a fast response instrument to complement new results from ALMA. Furthermore, APEX ensures southern hemisphere access for submillimeter projects complementing archival Herschel research as well as new SOFIA science.

The conference venue, Ringberg Castle, provides a unique setting for in depth discussions on current and future science with APEX. In particular, sessions on new scientific results, on synergies with other observatories and on the exploitation of the upcoming new APEX capabilities are envisioned.

The castle can accommodate about 60 to 70 participants. Registration will open Oct 1st at which point scientific contributions can be proposed.

In this workshop, we will discuss the many recent developments in the field, including mapping scattering screens using VLBI, using scintillation to spatially resolve pulsar emission and solve pulsar orbits, studies of plasma lensing in plasma-dense environments, physical models of scintillation, and ways to remove scintillation/scattering from a pulsar's intrinsic emission.

The scope of the workshop is to exchange ideas and solutions among the developers of radio-astronomical instrumentation in the frequency range below 100GHz, specially under the aspect of phased array feed systems.

After single pixel systems and discrete array receivers have been developed to sensitivities close to the physical limits, phased array feed systems are now the next logical step to further increase the science output of the observing facilities. These receiving systems with up to several hundred receiving channels introduce new technological challenges in all areas.

Very-long-baseline interferometry offers unprecedented resolutions in radio astronomy and is under continuous development. There is a long VLBI tradition both in Bonn (MPI für Radioastronomie) and Dwingeloo (ASTRON and JIV-ERIC), and both sites organise regular neighbourhood meetings since last century, in alternate years to the EVN Symposium. For 2019, Dwingeloo hosts the meeting.

Building on the success of the 2015/17 Ringberg meetings on spectroscopy with SOFIA at which about 70 participants discussed SOFIA results ranging from nearby star formation to the interstellar medium in nearby galaxies, SOFIA2019 aims at presenting new science results and looking into future science opportunities for the next years enabled by new instrumentation.

The workshop will include a session "SOFIA/APEX technological and scientific synergies" to honor the contributions of Rolf Güsten to both projects on the occasion of his retirement.

Now more than 12 years in operation, the Atacama Pathfinder Experiment (APEX) 12 m submillimeter telescope has significantly contributed to a wide variety of submillimeter astronomy science areas, ranging from the discoveries of new molecules to large and deep imaging of the submillimeter sky.

Since 2012 the Ringberg APEX workshops bring together APEX users working on a wide range of exciting results covering the Solar System to distance galaxies in the early universe. APEX2018 aims at presenting new science results and to looking into new science opportunities for the next years.

The Max Planck Institute for Radio Astronomy is happy to announce the workshop: "The Big Impact of a Big Dish: Science with the Effelsberg 100-m telescope", which will be held on 20-21 Feb, 2018 at the MPIfR in Bonn.

This meeting is intended to bring together various user groups of the 100-m telescope with the support staff of the observatory and the technical developers.

The topic of this workshop is : Neutron Stars in Future Research
 

The Young European Radio Astronomers Conference (YERAC) has been held annually in different radioastronomical centers in Europe since 1968 and has enabled many graduate students and young post-docs doing radio astronomical research to meet and present their current work. For a history of YERAC, see http://www.yerac.org .

YERAC will take place in Bonn for the fifth time. The Max Planck Institute for Radioastronomy, MPIfR, has agreed to provide the funding for board and lodging to all participants. Travel costs are expected to be paid by the participants' host institutes.

Participation is by recommendation only. Supervisors/directors of institutes are asked to nominate candidates and provide a supporting letter to yerac@mpifr-bonn.mpg.de . Each participant is expected to deliver a 15 minute talk about their work. The abstracts will be published electronically.

Recent developments have pushed the limits of resolution in astrophysics to new frontiers. Very-long-baseline interferometry (VLBI) at millimetre wavelengths or using antennas in space yields resolutions down to tens of microarcseconds (that is, fractions of nanoradians). These observations probe compact objects such as the innermost regions of active galactic nuclei. Space VLBI is living a new era at present with the results from the RadioAstron mission, enhancing radio interferometry in terms of resolution at least one order of magnitude with respect to ground-based VLBI. Millimetre VLBI also brings radio interferometry to a new range of resolution and with much enhanced sensitivity due to improvements in data bit rate. With more antennas capable of VLBI at 3-mm wavelength, and successful observations being carried out at 1-mm, a new window is open to universe at unprecedented resolution. This workshop will review recent results on high resolution radio astronomy, including opportunities provided by new antennas becoming available. It will also discuss on the applications of high-resolution imaging techniques and the synergies in the study of compact objects by space and mm-VLBI together. 

Contributions to the workshop will be published online in this webpage; no regular proceedings are planned.

CHANG-ES Workshop, Bonn, July 13-17, 2015

This is the sixth meeting of the DFG Research Unit FOR1254 on magnetic fields in the Universe, which is to review the achievements made during the second funding period, supported by invited review talks given by experts in the field. LOFAR is now routinely operational, while 'older working horses', partly upgraded, are being used to cover the higher frequency ranges (GMRT, JVLA). Significant progress has also been achieved in the Research Unit in terms of MHD modeling of galaxies and galaxy clusters, which alleviate and strengthen the interpretation of the observations and the resulting data products, and in the development of modern tools of data analysis.

This workshop is meant for members of the DFG Research Unit FOR1254. Participation of non-members is possible on request.

Ringberg Workshop on Spectroscopy with the Stratospheric Observatory For Infrared Astronomy (SOFIA) , Schloss Ringberg, Germany, March 15-18, 2015

The meeting "99 years of Black Holes - from Astronomy to Quantum Gravity" aims for bringing together experts from the research areas on Black Holes and Gravitational Waves, extending towards the future of General Relativitiy and Quantum Physics. This meeting will close the four-year long european funded COST Action "Black Holes in a Violent Universe". The conference is jointly organized by the COST Action MP0905, the MPI für Radioastronomie and the Albert-Einstein-Institut.

The formation of the Solar System, Bonn, 13-15 May 2014

With more than 900 confirmed exoplanets, it is becoming clear that there are many planetary systems with rather different properties to that of the Solar System. This poses the question how our own Solar System formed. The answer to this question is not straight forward, because it is based on hints from the current state on what happened in the past. It turns out that this is an interdisciplinary endeavour, requiring knowledge of supernovae explosions, meteorites, cosmochemistry, structure and evolution of circumstellar discs, star cluster dynamics, and the early dynamical evolution of planetary systems. The goal of this workshop is to provide a platform for information exchange between these different disciplines, putting together the puzzle pieces of the Solar System formation history.

The workshop focusses on:

• Cosmochemical constraints on the physical/chemical conditions in the Solar Nebula
• Time scales of the dust and planetesimal growth for the Solar System
• Models of the Kuiper belt formation
• The role of the stellar environemt, with emphasis on star cluster dynamics 
• Early planetary system development
• Future evolution of the Solar System

Contributions from related fields are welcome.
Registration is open from 1st December 2013. The workshop will be limited to 40 participants, early registration is recommended.

The main theme of this seminar is the observation and theoretical description of systems where gravity is strong and non-linear, in particular systems containing black holes and neutron stars which are ideal gravitational laboratories. To cover the complete complexity of this field of research, experts and graduate students from the observational and theoretical community are invited to bring together their expertise.

As a rough guideline, we have the following categories:

• Strong-field gravity in GR and its alternatives
• Black holes as strong field probes
• Neutron stars as strong field probes
• Gravitational wave observations and merger events

The program consists of invited as well as contributed talks and posters. We particularly encourage female scientist to contribute to the seminar. For young scientists we award the best poster with a price.

The number of participants is limited to about 70. All local costs (i.e., meals and accommodation) of the participants will be covered. The registration deadline is December 15th, 2013.
