White dwarfs, neutron stars and black holes — collectively referred to as compact objects — allow the study of a variety of open questions in fundamental physics.
The Stellar Afterlife and Transients (SALT) Team at the Institute of Astrophysics-FORTH, focuses on time-domain astrophysics and the study of compact objects. More specifically, the team is interested the formation and evolution of compact objects, and their use as test-beds for fundamental physics. This research is driven by long-standing questions, such as the radiative properties of strong-field gravity, the nature of super-dense matter, the origin of heavy elements and the mechanism of core-collapse supernovae (SNe). The SALT team combines multi-wavelength observations with theoretical modeling, while also maintaining an interest in novel instrumentation and data-intensive astronomy. The group also participates in the European Pulsar Timing Array (EPTA) and the Large European Array for Pulsars (LEAP) collaborations that work towards the direct detection of gravitational waves from supermassive binary black holes.
