Extragalactic jets on all scales - launching, propagation, termination
CANCELLED due to Covid-19
2020-03-21: The global crisis with regard to the pandemic COVID-19 has now forced us to
cancel the the conference
and postpone it to June next year (new date to be announce asap).
All 2020 participants will be re-contacted later this year.
2020-03-14: We still believe that the time frame of our conference is beyond the time scale for the COVID 19 pandemic infections, and therefore plan to have the conference as scheduled. Our further planning is on hold. We will continue to monitor the situation and will be as well constrained by political decisions.
As the situation develops fast, we may have more concrete information in about two weeks. See our more detailed information below.
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 following speakers have accepted
our invitation so far.
Talk titles will be provided asap.

The global crisis with regard to the pandemic COVID-19 has now forced us to cancel the conference and postpone it to June next year.
We will reimburse payed conference fees in due time.
All 2020 participants will be re-contacted asap.
We still believe that the time frame of our conference is beyond the time scale for the COVID 19 pandemic infections, and therefore plan to have the conference as scheduled.
Our further planning is on hold. We will continue to monitor the pandemic situation as well as constrains by political decisions.
Since the situation develops fast, we may have more concrete information in about two weeks.
So far we have taken the following measures:
a) Extension of the Early Bird registration to April 15, 2020.
b) In case a participant cancels after payment of registration fees, prior information has to be send to us before May 1, 2020 (6 weeks before the event) to get complete refund (i.e., in case the conference is carried out from June 15-19, 2020).
c) If the event needs to be cancelled by us, the registration fee will be paid back in full.
d) We hope to make a final call for the event on the latest by May 15th.
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.
The workshop is planned to start at 09:00 on Monday, 15 June, 2020 and to finish at 16:00 on Friday 19 June.
There will be a dedicated shuttle bus to bring participants from the town to the workshop venue (see details under travel below). We will organize for a daily lunch at the conference site. The conference fee will cover the cost of lunches at the workshop, the workshop dinner, and the bus shuttle.
Participants are responsible for organizing their travel to Heidelberg, and should make their own accommodation arrangements (see below).
Lunch and coffee breaks will be provided at the workshop venue on all days of the workshop. Vegetarian options will be available (no need to pre-order, but please mention your choice when registering online).
We will hold a workshop dinner on the Thursday evening at the conference site. This is foreseen to be a social barbeque (with also vegetarian options). Also, please tell us whether you will join the BBQ when you register online.
Participants are responsible for making their own accommodation arrangements. Heidelberg has plenty of hotel and airbnb options; Below we will come up with a a few hotel suggestions. Obviously, you better look for an accomodation close to the departures of our shuttle bus.
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.
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.
If you decide to rent a car and drive, you can follow these directions (to MPIA).
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.
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 2.70 € 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.
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).
Participants are responsible for making their own accommodation arrangements. Heidelberg has plenty of hotel and airbnb options; Below we will come up with a few hotel suggestions. Obviously, you better look for an accomodation close to the departures of our shuttle bus.
