Extragalactic jets on all scales - launching, propagation, termination

A workshop jointly organized by MPIA and IIT Indore


Energetic and collimated beams of plasma launched from the centre of galaxies have fascinated the community for a century. In spite of the advancement in observational and theoretical modelling techniques, many aspects regarding the detailed physics of extra-galactic jets remain not fully understood. This conference aims to push forward our understanding of extra-galactic jets bringing together experts from theory and observations.

The main focus shall be on the theoretical side. One major aim of this conference is to demonstrate recent advances in the multi-scale numerical modeling of jets and to discuss strategies for how to better constrain simulations with multi-wavelength and high-resolution observational data. Another focus shall be the universality of jet properties and understand what we can learn from other jets sources such as non-relativistic jets or GRBs.

The conference addresses the astrophysics across all scales of the jets from :
- the launching scale that governs the jet energetics and matter content
- the propagation scale involving magnetic dissipation, particle acceleration and non-thermal radiation, jet stability and variability
- the termination scale that is essentially connected to IGM and ICM feedback and the FRI/FRII jet power

Present and future sensitive radio facilities, such as VLA, LOFAR, EHT, and SKA, together with those extending the coverage over a full multiwavelength range, will be crucial for unraveling the jet physics at all spatial scales. This conference should be a platform to discuss state-of-the-art astrophysical approaches which can successfully bridge between numerical simulations, theoretical models, and multi-wavelength/multi-messenger observations.

In particular we would appreciate contributions on the following topics:
- Jet launching GR-MHD simulations
- Jet stability and variability
- Jet energetics : heating, dissipation, feedback
- Emission and Polarization - observed and simulated
- Particle Acceleration Mechanisms
- Essential observational inputs for theory
- Universality of jet properties

The conference will be part of bilateral initiative between IIT Indore and the MPIA Heidelberg through the Max Planck Partner group.

After your online registration (that we use to organize the conference), please proceed and pay the conference fee. This is handled by the company ZTIX, external to MPIA.


The Program will be uploaded in May 2020

We plan for a few invited reviews, our emphasis is to offer a platform in particular for young scientists. Our plan is to restrict the participation to 75-80 people considering both space availability and other logistics.
Ideally, we would like to stress upon the fact to have more panel discussion sessions involving young scientists that will lead the community in the next phase. Also, we wish to have poster session to be flash talks rather than the conventional display of poster on boards as it will give young students a unique opportunity to showcase their research.

The workshop will be held at the Haus der Astronomie (HdA) at MPIA in Heidelberg. HdA is the Center for Astronomy Education and Outreach in Heidelberg; more information about the center and its facilities and resources can be found here.

Visa and Flight Information

You may need to apply for a visa to enter Germany. For information by country, see this overview of visa requirements.

We recommend that you fly into Frankfurt Airport (FRA), as this is the nearest international airport to Heidelberg. The following directions to Heidelberg assume that you are starting from Frankfurt.

Getting to Heidelberg


Deutsche Bahn (DB) has connections from Frankfurt Airport (station: Frankfurt(M) Flughafen Fernbahnhof) to various train stations around Heidelberg (likely either Hauptbanhof or Altstadt, depending on where your hotel is). Typically you will take a train to Mannheim and then change platforms there to the S-bahn to Heidelberg. The total travel time is of order one hour. Tickets cost about 25 € each way. The time table is available here. You can buy a ticket in advance, but we don't recommend the cheaper "saver" tickets, as these are tied to a particular train, so won't be valid if your flight is delayed.


A cheaper but slower alternative is the "Flixbus" from the airport to Heidelberg. Prices range from 5-15 € each way, but depending on the time of day the trip could take up to three hours due to stops and traffic. To investigate time tables and book tickets, you can check out the Flixbus website or app.


The two best shuttle options are Transfer & Limousine Service (TLS) (40 € each way) and Lufthansa Express Shuttle (25 € each way).

Driving directions

If you decide to rent a car and drive, you can follow these directions (to MPIA).

Getting to HdA

There will be a shuttle to transport participants from the town centre up the hill to MPIA/HdA every morning. It will leave at or near the Lufthansa bus stop on the west side of the Crowne Plaza Hotel (check this map) on Bahnhofstrasse at 08:15 (bus/company name "discipulus"). It will then stop briefly to pick up at Peterskirche (the stop on the south side of road, i.e. the one closest to the hill) at 08:20 (the bus might only arrive five minutes later here, but be there no later than 08:20 as the bus cannot wait). A local participant will be at each of the pick up points and will travel with the bus. A bus will bring participants back into town (the same two stops) after the workshop each day (except Tuesday, when we have the dinner).

At other times of the day you can take Bus 30 - the "Science Bus" - up to MPIA (the bus will drop you off right outside HdA) or back down the hill (you probably want to get off at Peterskirche). A map of the entire bus/tram network is here (the MPIA is slightly below and right of the centre). You can buy tickets online or at ticket machines or (if that fails) from the driver on the bus (the cost is approximately 2.50 € each way). Note that where the Science Bus departs - Universit??tsplatz - to go up to MPIA is not far from Peterskirche. There is a also a taxi stand near there if all else fails.

Exploring Heidelberg

The easiest way to explore Heidelberg is by foot. Public transportation in Heidelberg is provided by the Rhein-Neckar-Verkehr (RNV) in the form of buses and trams; these can take you more or less anywhere you want to go within the city. The timetables can be found online; you can also download various apps to help you plan, e.g. the official RNV app (in german) or the VRN Ticket app (in english).
