Science with the Atacama Pathfinder Experiment (APEX), Schloss Ringberg, Germany, February 02-05, 2020
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.
Scintillometry 2019, Bonn, Germany, November 4-8, 2019
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.
PAF Workshop 2019, Bonn, Germany, September 16-18, 2019
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.

Dissecting the Universe - Workshop on Results from High-Resolution VLBI, Bonn, 30 November to 02 December 2015
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 annual meeting of the international consortium of the CHANG-ES project, in which 35 nearby edge-on galaxies have been observed with the EVLA in C- and L-band in three different arrays in radio continuum and polarization. The aim of the project is to study galactic halos, the interface between the disk's interstellar medium (ISM) and the intergalactic medium (IGM). From the observations we will address questions like how do halos depend on the star formation rate or other in-disk activities or what role do magnetic fields and cosmic rays play in the dynamics of extraplanar matter.
The workshop is mainly meant for consortium members. Non-members are welcome on Thursday and Friday (July 16-17).
Magnetisation of Interstellar and Intergalactic Media: The Prospects of Low-Frequency Radio Observations, Schloss Ringberg, Germany, July 1-4, 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
Since 2010 the Stratospheric Observatory For Infrared Astronomy SOFIA) has started contributing to a wide variety of far-infrared (FIR) and mid-infrared (MIR) astronomy science areas, ranging from the discovery of new light molecules to detecting dusty protostars in star forming regions (including infall motion and collapse), thereby significantly complementing and extending the heritage of the recently ended Herschel and Spitzer science missions. SOFIA has completed its major development phase and is now in full operation.
This workshop will be in honor of Eric Becklin, chief scientist and long-term strong supporter of SOFIA, on the occasion of his 75th birthday.
The castle can accommodate about 60-70 participants.
Registration and abstract submission are now open with a deadline January 22nd, 2015.
Extreme Astrophysics in an Ever-Changing Universe - Time Domain Astronomy in the 21st Century | Celebrating John Seiradakis' 40-year career, Ierapetra, Greece, June 16-20, 2014
Today we know that most phenomena observed in “time-domain” astronomy are related to extreme astrophysical events or processes. Whether it is the explosion of stars in supernovae or the observations of flare stars, pulsars, gamma-ray bursts, blazars or active galactic nuclei, time-domain astronomy stretches across the whole electromagnetic spectrum and beyond. With increasing technical capabilities, the 21st century will see corresponding new instruments being developed or coming online, revolutionising our view of the ever-changing Universe.
Our ambition is to bring together different research communities and provide a platform for an exchange of ideas, experience and methods that may prove invaluable in promoting the unification of time-domain astronomy. Further, to approach these methods qualitatively similarly as probes of very different scale physics in which different effects become dominant at different systems.
The conference also celebrates the career of Prof. John H. Seiradakis, who over the last 40 years has contributed to the field in many aspects.
The participation is limited to strictly 80 participants. Early registration is therefore highly recommended.
99 years of Black Hole - from Astronomy to Quantum Gravity, Potsdam, May 20-22, 2014

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.
558th WE-Heraeus-Seminar on "The Strong Gravity Regime of Black Holes and Neutron Stars", Physikzentrum Bad Honnef, 31 March to 4 April, 2014
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.

The Modern Radio Universe 2013, Bonn, 22-26 April 2013
80 years ago, in spring 1933, Karl Jansky published his discovery of cosmic radio emission. This paved the way not only for a new discipline, radio astronomy, but also for an exploration of the universe that now encompasses almost the entire electromagnetic window. Today, radio astronomy is about to enter into yet another new era with a number of new or upgraded radio facilities coming online and major new initiatives, like the Square Kilometre Array (SKA), are starting up. This conference will try to highlight the original and exciting science currently being produced by radio astronomical telescopes, such as the GBT, Effelsberg, LOFAR, ALMA, the JVLA, eMERLIN, EVN, VLBA, as well as pathfinder experiments of the SKA, and others. Science areas that will be discussed are among others: Cosmology, galaxy evolution, AGN and compact objects, star formation, interstellar medium, The Milky Way and Galactic science, radio transients, fundamental and astroparticle physics, extreme physics and associated theory. This fresh view on the radio universe will improve our current knowledge of the universe and highlight new trends in radio astronomy. The science delivered by the radio astronomical community addresses key questions in modern astrophysics that may lead us to even more ambitious science goals to be targeted by future radio facilities like the SKA.
Radio Interference with Large Bandwidth Observations, Bonn, 8-12 April 2013
