Photometric monitoring of quasars

We study the variability of active galactic nuclei (a.k.a. quasars), which trace episodes in the lifetime of galaxies whose central black holes are in the phase of rapid growth.

Polarimetric monitoring of quasars

We map the innermost environs of active supermassive black holes by studying polarization signatures from radio-quiet sources. Specifically, we aim to shed light on the various scattering processes that take place near the black hole, be it due free electrons or dust.
