Selected meetings organized by our department.
The CoViD-19 restrictions prevent the organisation of face-to-face meetings. Online conferences co-organised by our department will be included here.
Due to the restrictions imposed by the CoViD-19 pandemic, most of the face-to-face meetings in 2020 were cancelled. Several meetings were held in the form of a virtual meeting, via teleconferencing. Here a selection of the ones co-organised by the MPIfR Radio Astronomy/VLBI department.
December 4-14, 2020: Event Horizon Telescope Virtual Collaboration Meeting
The Event Horizon Telescope had planned its collaboraiton meeting in November in Taipei, Taiwan. The travel and social contact restrictions imposed by the CoViD-19 pandemic forced to re-schedule the meeting as a virtual event. The meeting included closed sessions for the collaboration members and several plenary talks with external guests, namely: the 2020 Physics Nobel Laureate Andrea Ghez from UCLA, Dame Jocelyn Bell Burnell from the Univ. of Cambridge, the 2017 Physics Nobel Lauereate Kip S. Thorne from Caltech, Sasha Tchekhovskoy from Northwestern Univ., and Tony Beasley from the National Radio Astronomy Observatory.
The scientific organising committe consisted of Geoff Bower, Chi-kwan Chan, Mariafelicia De Laurentis, José L. Gómez (chair), Kazuhiro Hada, Kari Haworth, Alejandra Jimenez Rosales, Cheng-Yu Kuo, Venkatessh Ramakrishnan, and Huib van Langevelde. The "local" organising committe consisted of Juan Carlos Algaba, Yuzhu Cui, Joseph Farah, Raquel Fraga-Encinas, Rocco Lico (chair), Lia Medeiros, Hiroki Okino, Arash Roshanineshat, Naeun Shin, Alex Tetarenko, and Thalia Traianou (MPI für Radioastronomie)
September 26-27, 2019: EU-VGOS Workshop
Worskhop to discuss the European work on scheduling, postprocessing, and analysis of the VGOS data in Europe. More information available here.
July 15-19, 2019: Event Horizon Telescope Polarimetry Workshop
The MPI für Radioastronomie hosted the Polarimetry Workshop of the EHT collaboration in July 2019, to discuss the data analysis, including tutorials and work of parallel teams to calibrate and image the polarised emission of the sources observed with the Event Horizon Telescope. The Scientific Organising Committee consisted of Kazu Akiyama, Lindy Blackburn, Katie Bouman, Andrew Chael, Jason Dexter, Ciriaco Goddi, José L. Gómez, Sara Issaoun, Michael Janssen, Michael Johnson, Jae-Young Kim, Thomas Krichbaum, Ivan Martí-Vidal, Monika Mościbrodzka (chair), John Wardle, and Maciek Wielgus. The Local Organising Committe consisted of Jae-Young Kim, Rocco Lico, Thalia Traianou, Felix M. Pötzl, Anne-Kathrin Baczko, Eduardo Ros, and J. Anton Zensus.
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.
