Late bursts of star formation in normal elliptical galaxies

Late bursts of star formation in normal elliptical galaxies

Late bursts of star formation in normal elliptical galaxies We normally think of elliptical galaxies as massive, stellar systems which are quasi-spherical, filled with old stars and hot gas and essentially quiescent objects. Successful simulations find them made at...

Binary black hole populations with LIGO/Virgo

Binary black hole populations with LIGO/Virgo The LIGO and Virgo detectors have observed several gravitational waves from mergers of compact binary objects, mostly binary black holes. These discoveries have allowed starting characterizing the astrophysical population...
