HE1: Extragalactic Transients
Carole Mundell (Liverpool John Moores University, UK), Stefanie Kommossa (Technical University Munich, Germany)
The time-variable sky is the next observational frontier and major new facilities, like LOFAR and LSST, are expected to revolutionise discovery of transient phenomena. Today, however, a growing number of discovery and rapid-response facilities with ever-improving capabilities are already opening this time domain.
Extragalactic transients trace physics under extreme conditions: the strongest gravitational and magnetic fields, most extreme tidal forces and explosive energy releases. They provide tight constraints on our understanding of accretion physics, jet formation, and ultimately may deliver long-elusive gravitational waves. Their huge peak luminosities allow us to detect them out to large cosmological distances and back to the earliest cosmic times.
The goal of this session is to bring together leading UK and German observers and theorists across the fields of gamma-ray bursts (GRBs), supernovae (SNe), stellar tidal disruption flares (TDFs) and Active Galactic Nuclei (AGN) variability, triggering and fuelling, to exploit the strong synergies and links between them, both in the underlying physical processes and their survey-search/follow-up techniques and strategies. The link between this broad-reaching set of time-variable phenomena represents a cutting-edge interface between complementary communities and their techniques and holds much promise for progress; e.g. recent Swift satellite discoveries of distant galactic centre flares.
Abstracts are invited presenting new results in any of these astrophysical areas - observation, theory and instrumentation/technological capability - and particularly at the interface between them. We also encourage abstracts on multi-messenger campaigns such as neutrino and gravitational waves combined with EM signatures.
