Cologne-Prague-Brno meeting 2022

Black-hole activity feedback from Bondi-radius to galaxy-cluster scales

2022 June 1-3 * Brno, Czechia


Brno is the second largest city in the Czech Republic. It is the capital of the South Moravian Region with a population of almost 400.000 people. It is a modern city with a focus on high-technology industry, trade, science, information technology, research and innovation with business incubators and centres of excellence in science. Brno is a city of universities with more than 86,000 students and 3 university campuses. Most of the Czech space industrial companies are located in the Brno technological park. It is a dynamic lively city with plenty of restaurants, shops and cultural centres. While it only has a small international airport, there are train/bus connections to larger airports in Vienna and Prague. More information on logistics will be communicated at a later date.

The host institute is the Institute of Theoretical Physics and Astrophysics, Faculty of Science, Masaryk University, which is currently one of the most productive and progressive astronomical institutes in the Czech Republic.


The CPB2022 meeting will take place at the Brno Observatory and Planetarium. This modern and architecturally beautiful venue in a hilltop park, with great views, in the middle of Brno, is ideal for medium size conferences. It provides modern audiovisual equipment, excellent Wi-Fi connection and additional rooms for side meetings and discussions. The venue provides much needed flexibility, including the possibility of organising a hybrid event, with part of the participants connected remotely.


Brno Main Railway Station (Brno Hlavní nádraží) is reachable by direct train connections from Prague and Vienna. The Main Railway station (Brno Hlavní nádraží) is located essentially in the city center close to Náměstí Svobody. When you travel from Brno Hlavní nádraží to the meeting venue - Observatory and Planetarium Brno (Hvězdárna a planetárium Brno) - the easiest is to take tram number 4 to the square at the top of Kraví hora (305 meters above the sea level; German: Kuhberg or Urnberg; hantec: Monte Bú, folk: Kravák; English: Cow Mountain) - Náměstí Míru. The Brno Planetarium and Observatory is then within 5 minutes of walking distance across the nearby park (see the map below).

For planning the travel itinerary and buying the train tickets to Brno from Prague or Vienna, the best option is to use the portal of Czech railways or Austrian railways. For Polish participants, the best connection to Brno is via Ostrava-Svinov. To Ostrava-Svinov, you can find connections from Warsaw or Kraków via the PKP webportal .


You can search for convenient hotels in Brno at or airbnb. A convenient option - also for students - is B&B Hotel University Brno. Then we can also recommend Hotel Kozák, Hotel Continental, and Hotel International. In case you are currently having a nuclear-war anxiety, you can consider booking accommodation in the nuclear shelter 10-Z.
