From Scaling Black Holes to Measuring Dark Matter in Galaxies

Th e supermassive black hole residing at the galaxy center is expected to co-e volve with the host galaxy. An evidence of this co-evolution is the relatio n observed between supermassive black hole mass and the host galaxy propert ies.
I will talk about the latest supermassive black hole scaling rel ations that we discovered during my Ph.D. Given our telescopes have a limit ed resolution, these scaling relations are used to estimate the mass of the black holes at the centers of distant galaxies.
I will also talk abo ut a naturally occurring phenomenon called 'gravitational lensing', which h as become a powerful tool for astronomers to measure the 'dark matter' whic h is invisible but has a mass and constitutes most of the matter in the Uni verse. I am using the observations of 'gravitational lensing' to measure da rk matter in galaxies and trying to understand their role in shaping the ga laxy forms that we observe.
