Focus of the Workshop

High angular resolution techniques at infrared and centimeter to millimeter wavelengths have become of ever increasing importance for astrophysical research in the past decade. They have led to important breakthroughs, like the direct imaging of protoplanetary discs and of the first exoplanets, the measurement of stellar orbits around the black hole at the center of the Milky Way, or the detection of sub-parsec-scale jets in low luminosity AGN. With adaptive optics in a mature state, infrared/optical astronomy is pushing toward extreme adaptive optics, extremely large telescopes, and infrared/optical interferometry with large aperture telescopes. At longer wavelengths, large arrays start to conquer the sub-millimeter window, with the mid-term goal of global VLBI at sub-millimeter wavelengths. These new techniques will have enormous impact on the field because they will enable us to address issues such as directly measuring the properties of exoplanets, imaging the surfaces of stars, examining stellar dynamics in extremely dense cluster cores, disentangling the processes at the bottom of black hole accretion flows in the jet launching region, or testing general relativity in the strong gravity regime near the event horizon of supermassive black holes. This conference aims at an interdisciplinary approach by bringing together astrophysicists from the three great branches of the field, instrumentation, observation, and theory, to discuss the current state of research and the possibilities offered by the next-generation instruments.


Date and Location

AHAR 2011 is going to take place from 29. August - 2. September 2011, with 28. August and 3. September as potential arrival and departure dates. Venue is the Physikzentrum Bad Honnef. The Physikzentrum Bad Honnef has been serving as the main meeting point of the German Physical Society (DPG) since 1976. It offers a secluded setting for research conferences, seminars, and workshops. The mansion housing the Physikzentrum is located in the small town of Bad Honnef, at the foot of the Siebengebirge ("the Seven Hills") on the right bank of the Rhine river south of Bonn, about 40 km south of Köln. The lecture hall in the Physikzentrum is one of the best of its kind. It offers seating to up to 120 participants with a modern double rear projection, interactive electronic board, full video conferencing equipment, and acoustics that makes using the audio equipment in many cases superfluous. Technical equipment includes data-, overhead- and videoprojection, poster- and blackboards, and wireless internet access. Downstairs a comfortable and cosy clubroom invites for discussions and extended talks in the evenings.

Number of Participants

Due to the limited capacity of the conference center and in order to provide a good atmosphere for discussions and scientific exchange, there will be a hard upper limit of 120 participants


The conference fee is 550 Euros, what includes the refereed proceedings, conference management, taxes, full board and the conference dinner on a restaurant ship on the river Rhine. Participants have to organize their own accomodation. Lodging in the Physikzentrum is possible and we also have a number of rooms in a good hotel at hand. Prices for rooms (including breakfast) are ranging from 26 Euros to 60 Euros per day (details can be found here)

Some financial support for students will be available. Please contact the LOC if you are in need of financial assistance. The LOC/SOC may grant stipends in certain cases. A criterion for eligibility is the relevance of the contribution of the applicant to the conference.


Upon request we can deliver a letter of invitation.


The following procedure has been adopted for registration:
There is an obligatory pre-registration which opens February 15th. At pre-registration, potential participants provide information on whether they would like to present a talk or a poster, together with a preliminary short abstract (there is also an option for "no presentation"). Based on this information, the SOC/LOC will select presentations relevant to the topic of the workshop. Until May 15th the SOC/LOC will inform all registered persons concerning the status of their acceptance and the selected type of presentation. Accepted participants will be forwarded a internet link with the instructions for final registration and payment of the conference fee. The deadline for final registration and payment of the conference fee will be June 30th.
Please be aware that due to the time constraints of the workshop the final decision on the form of your presentation will be taken by the SOC/LOC.

Organizer and Sponsors

The Central Kiloparsec in Galactic Nuclei, AHAR2011 is organized by the 1. physics institute of the university of Cologne, Germany. The workshop is sponsored by the Max-Planck-Institut für Radioastronomie (MPIfR) in Bonn (Germany) by COST and by the SFB 956.
