Symposium S11  26 – 27 June 2017

A multi-messenger look at the origin of gamma-ray bursts

Aims and scope

The origin of gamma-ray bursts (GRBs) – some of the most energetic events ever detected – is still a mystery today, 50 years after their discovery. However, in the era of multi-messenger astronomy, we can take a fresh look at their underlying physics. With gamma-ray and X-ray observations from active space missions such as Fermi, Swift, MAXI, INTEGRAL, Konus, AGILE, NuSTAR, CALET, Lomonosov and AstroSAT; with afterglow observations in radio (e.g. MeerKAT), optical and X-ray; and with future facilities like CTA, Athena and SVOM, it is now more important than ever to connect our theoretical understanding of GRB physics to these multi-wavelength observations.

Indeed, there are several open questions regarding the origin of GRBs: What are the prospective progenitor systems? What powers the central engines? How does the circumstellar environment influence the afterglows? What are the connections between various supernova classes and GRBs? How strong is their dependence on the host galaxies' metallicities? And if it is still difficult to reach a conclusion on these questions, what are the directions we shall proceed in the future?

Furthermore, after the discovery of astrophysical neutrinos by IceCube and that of gravitational wave signals by LIGO, the role that GRBs may play in these new fields of astrophysics needs to be investigated. Should we expect gravitational wave signals to be accompanied by an electromagnetic emission of any wavelength? Should we expect GRBs, either short- or long-duration ones, to contribute to the astrophysical neutrino background?

This Symposium, which not only celebrates the 50th anniversary of discovering GRBs but the 20th anniversary of discovering afterglows, aims to bring together scientists working either on these multi-messenger/wavelength observations or on theoretical modeling. A special emphasis is put on dialogue and mutual comprehension. The different fields of astrophysics tend to have not only different techniques and working methods, but sometimes even heterogeneous terminology. Therefore, we encourage our speakers to make their message clear by using terms and expressions carefully chosen to an audience of general astronomers. This approach will not only ensure the success of the meeting by forging new collaborations between far-away fields, but will also promote equity and fair-play between junior and senior, as well as native and non-native English speakers.

Additionally, we aim for gender balance in this meeting, making sure that no gender group takes up more than approx. half of our invited speakers and chairs.

Contributions not selected for an oral presentation will have a chance to be presented as posters. A proceedings volume of the workshop will be issued.
