The Extreme Objects working group at the Oskar Klein Centre summons researchers working on the most compact and energetic astrophysical objects in the universe. Much of the research connects to transient objects, like supernovae, gamma-ray bursts, active galactic nuclei, and macronovae. Observationally, group members have engagements in the Zwicky Transient Facility to observe transients at optical wavelengths, and in FERMI to detect the transient gamma-ray sky, as well as the IceCube neutrino observatory. A group at KTH has developed their own X-ray polarisation balloon experiment (PoGO) to probe the Crab Nebula and the black hole Cygnus X1. Theoretical work on relativistic hydrodynamics underpins such efforts, just as theoretical exploration of supernova spectral synthesis and prompt emission from gamma-ray bursts accompany the observational programs.
Meetings and Contact
The Extreme Objects working group meets bi-weekly and meetings often include two presentations from members or visitors.
