Symposium Outline


The idea is to discuss the basic topics of high energy astrophysics in their connection to gamma-ray astronomy at energies between 1 GeV and 100 TeV.

The general topic of the Symposium is the continuum gamma-ray emission from cosmic objects and its physical interpretation, in terms of theory and in a multi-wavelength observational context - including regimes of ground-based as well as space-based observations. A special role play here also the nonthermal radio to X-ray and low-energy gamma-ray emission bands. Related activities in high energy neutrino astrophysics and regarding high energy cosmic rays will as well be covered by review talks.

The next year will see results from large ground-based gamma-ray observatories of the new generation, with imaging atmospheric Cherenkov telescopes and thresholds below 100 GeV. They cover both the Southern and the Northern hemispheres. Thus it appears timely to discuss these results in the above broad perspective.

We expect about 200 participants or more. Four morning sessions will be allocated for invited talks to cover the topics outline below. On three days, there will be poster sessions of 1 hour during prime time in the afternoon. After the poster sessions, afternoon sessions from 16:00 - 18:00 will, in addition, include specific projects and multi-wavelength observations. On the one free afternoon there will be a boat trip in the Neckar Valley.

The Symposium is planned to consist of the following four parts:

Venue and Social Events


The symposium will be held in the Heidelberg Stadthalle (City Convention Center), which is centrally located in the beautiful Altstadt (Old Town) and easily accessible by public transport. The Stadthalle can be seen on the riverside in the centre of the picture below.


Heidelberg is the oldest University town in Germany, dating back to the 12th Century. Situated on the banks of the Neckar river and nestled between two local mountains, it is also one of the most picturesque. Heidelberg also sees over 4 million visitors per year, peaking in the summer months (Jun - Aug). The summer weather is usually sunny with average maximum temperatures in the range 20-25 deg C. Being a university town, Heidelberg is considered quite lively for its size with ample restaurants and bars to pass the time.

Naturally, we encourage participants to take advantage of the good weather (hopefully), and to explore what Heidelberg has to offer in their spare time. More detailed information on Heidelberg attractions can be found on this web page, which has a number of useful links (including an interactive city map)

Social Events

The social events associated with the symposium will include a cruise along the Neckar river, temptatively scheduled for Wednesday afternoon (July 28). This trip is included in the conference fee.
On Thursday evening, a symposium banquet will be held in the Heidelberger Kulturbrauerei in the old town of Heidelberg (Leyergasse 6). This will cost an extra 35,- Euro per person and can be booked together with the registration.

Travel Information

How to come to Heidelberg


If you want to come by plane, the airport of choice from most places in the world is Frankfurt Airport. It is about one hour by train, coach, or car from Heidelberg. Alternative airports are Stuttgart, Baden-Baden, and Frankfurt-Hahn.

Schematic view of Frankfurt Airport. For a more detailed map see here.


Frankfurt Airport -> Heidelberg by train

Frankfurt Airport has 2 train stations. One is for regional trains ("Regional-Bahnhof" or "Regiobf"), with platforms 1-3, the other one is the long-distance railway station, platforms 4-7. You should make your way to the long-distance railway station ("Fernbahnhof" or "Fernbf") which is shown at the bottom of the map.

Only very few trains go directly from Frankfurt Airport to Heidelberg. So you should get the next available train to Mannheim. You can schedule your railway trip here.

Trains to Mannheim leave typically twice per hour, so not too much planning is required. However, you should better get a ticket beforehand.

The long-distance train station has 2 levels: you enter at the top level, where you find a ticket office and ticket machines. Buy a ticket to Heidelberg, taking into account which train you will take, because there are different prices for different trains. For the ICE, it is typically 22 EUR. All common credit cards and cash are accepted.
You can also purchase tickets in trains. But be careful: entering an S-Bahn or other local area train without a valid ticket is not allowed and might cost you a fine of 40 EUR plus the normal price. Purchase tickets on the train only if you go with an EC, IC, ICE train. If you can: get your ticket beforehand!

The train takes about 30 minutes to Mannheim, which is the first stop. You have to change at Mannheim. Trains to Heidelberg go very often, and take only about 15 minutes. Your destination is "Heidelberg Hauptbahnhof". Here you can get a taxi, a bus or a tram -- see also local transport info (VRN).


Frankfurt Airport -> Heidelberg by door-to-door shuttle service

There is an Airport Shuttle Service that picks you up from Frankfurt Airport either at the exit of Terminal 1 or the meeting point in Terminal 2 and brings you to your Hotel in or outside Heidelberg (door-to-door), or vice versa (takes 1 h). It costs 28 EUR per person (one way to Heidelberg). You can book it also by phone or fax a few days before your arrival/departure:
TLS Transfer & Limousine Service, Tel.: +49 (0) 6221 77 00 77, Fax +49 (0) 6221 77 00 70


Frankfurt Airport -> Heidelberg by Lufthansa bus

Lufthansa provides an Airport Bus between Crowne Plaza Hotel (Heidelberg) and Frankfurt Airport Terminal 1 B (i.e. arrival level, meeting point domestic and international flights). This service is open also to customers of other airlines. Lufthansa (and some allied airlines) passengers can even check in at Crowne Plaza Hotel. Price for the bus trip: 19 EUR one way or 35 EUR return.
For more information/reservation call +49 (0) 01803 803 803.
