Observations of the centres of galaxies reveal the hidden destruction of stars by lurking supermassive black holes (Dissertation defence Nov 4 2021, MSc Thomas Reynolds, astronomy)

We know that in the centres of the majority of galaxies lies a supermassive black hole. New observations of certain galaxies reveal that these black holes may be consuming stars at a higher rate than previously known. The energy produced by the destruction of the star can be revealed in the infrared, as heat from cosmic dust warmed by the explosion.

Polarization of Light Helps to Better Understand Emission Sources in the Vicinity of Stellar-Mass Black Holes (Dissertation Defence, MSc Ilia Kosenkov, 8 Oct 2021, Astronomy)

Stellar-mass black holes that are part of binary systems sometimes show variable polarization of optical emission. The degree, angle and variability pattern of polarization is characteristic of the physical processes occurring in the vicinity of a black hole. By studying black holes astronomers learn how matter and energy behave under extreme conditions.
