February 20-22, 2018 - The big impact of a big dish: Science with the Effelsberg 100-m Telescope
Even more than 40 years after its inauguration, the 100-m telescope is still one of the two largest fully-steerable radio telescopes in the world, and — due to continuous efforts by the institute and the Max Planck Society — in an excellent shape. It is heavily used for astronomical observations and accessible by users from all over the world due to its "Open Skies" policy.
This meeting was intended to bring together various user groups of the 100-m telescope with the support staff of the observatory and the technical developers. We are looking forward to the opportunity to discuss recent observational results and technical developments with the users of the 100-m telescope. Furthermore, this meeting will give us the possibility to learn about new ideas for observing projects and will allow us to plan technical and software developments for the next years.
December 13-15, 2017 - Blazars at the highest resolution workshop (Humboldt partnership)
The MPI für Radioastronomie in Bonn and the Astro Space Centre of the P.N. Lebedev Physical Institute of the Russian Academy of Sciences are collaborating in the framework of a Humboldt Partnership Program, with the main focus of the collaboration laid on the space VLBI mission "RadioAstron". Marking the the second year of the Program, a workshop took place in Bonn on December 13-15. The workshop also embracesd a number of external collaborators of the Program, with participants from Instituto de Astrofísica de Andalucía, Aalto University, and the Istituto di Planetologia e Astrofísica Speziali. The first day of the workshop (December 13) was open for the general public, featuring presentations about key science projects of the RadioAstron and their potential synergies with the GMVA and EHT observations. The event was partially supported by the Alexander von Humboldt Foundation.
July 4, 2017, Bonn-Dwingeloo Neighbourhood VLBI Meeting
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. In 2017, Bonn hosted the meeting.
June 12-16, 2017 - Polarised Emission from Astrophysical Jets, Ierapetra, Greece
The conference aimed at a comprehensive coverage of the theoreticaland observationalaspects related to linearlyand circularlypolarized emission observed from extragalactic(AGN, GRBs) as well as galactic (e.g. XRBs) astrophysical jets, and its potential to reveal the physical conditions and emission processes governing these sources.
The meeting focused on current polarimetric monitoring programs, as well as high angular resolution interferometric observations, and prospects for new facilities (i.e., ALMA, SKA, EHT, XIPE, e-ASTROGAM). Special attention will be paid on reviewing current models for linear and circular polarization (including Faraday effects), and its relation to the jet magnetic field topology, composition, propagation, and formation.
Contributions in the following topics were invited:
- Theories for linear and circular polarization emission models
- Propagation of polarized emission and Faraday rotation effects
- Magnetic field structure and its role in the jet dynamics
- Jet formation and composition
- Polarization variability
- Polarimetric monitoring programs
- High angular resolution polarimetric observations
- Prospects for high energy (X-ray, gamma-ray) polarimetry
The conference was hosted at the Foundation of Cultural and Social Care of the Metropole of Ierapetra and Sitia in the Southern coast of Eastern Crete.
November 30-December 2 - Dissecting the Universe - Workshop on Results from High-Resolution VLBI
This workshop reviews recent results on high resolution radio astronomy, including opportunities provided by new antennas becoming available. This includes mm-VLBI, both at 3-mm and 1-mm, and space VLBI, with special focus on the RadioAstron mission. It discusses as well on the applications of high-resolution imaging techniques and the synergies in the study of compact objects by space and mm-VLBI together.
June 15-19, RadioAstron International Science Council & Science Teams Meeting
The RadioAstron International Science Council held its 2015 meeting at the MPIfR in Germany on June 15-16, followed by a colloquium on June 17. This event served as occassion for the science teams working on RadioAstron data to visit Bonn and work together during the complete week, from June 15 to 19.
The one-day workshop reviewed the historic developments of VLBI, and used this overview as ramp for discussing the VLBI prospects for the coming decade. The creation of the European VLBI Network, the pioneering and deep radio surveys, the study of gravitational lenses, technical developments in astronomical and geodetic VLBI, superluminal motions in quasars and radio galaxies, advancement of phase-referencing and astrometric methods will be at the focus of this discourse, bringing together a broad fraction of the worldwide VLBI community and providing a forum for deep and fruitful discussions.

July 31 - MPIfR - Workshop in AGN Physics
Workshop on theory and observations of AGN jets.
May 20-22 - Potsdam - 99 years of Black Holes - from Astronomy to Quantum Gravity
Closing meeting of the COST Action MP0905 on 'Black Holes in a Violent Universe'. The aim of the meeting was to bring together the Black Hole community (from Quantum to supermassive) as well as the Gravitational Wave Community. Main topics clustered around Black Holes, Gravitational Waves and the Future of General Relativity and Quantum Physics.
December 2 - Bonn-Dwingeloo Meeting
Neighbourhood meeting on VLBI science with speakers from Bonn (MPIfR & AIfA) and Dwingeloo (ASTRON & JIVE).
September 16-19 - Ioannina, Greece - Summer School on Black Holes at all Scales
Black Holes in a Violent Universe” (MP0905) organized a Summer School with a program including reviews on various aspects of Black Hole-related science, such as: demographics and formation theories of galactic black hole binaries in our and nearby galaxies, our "own" supermassive black hole on the Galactic center, formation and cosmic evolution of supermassive black holes, phenomenology of active galactic nuclei and a review of their "unification" theories, theory of jet formation and energy extraction in black hole systems, as well as the scaling of accretion and jet physics from mini-quasars to quasars.
