We first present a short overview of X-ray probes of the black hole region of active galaxies (AGN) and then concentrate on the X-ray search for supermassive black holes (SMBHs) in optically non-active galaxies. The first part focuses on recent results from the X-ray observatories Chandra and XMM-Newton which detected a wealth of new spectral features which originate in the nuclear region of AGN. In the last few years, giant-amplitude, non-recurrent X-ray flares have been observed from… 

An outflow powers the optical rise of the nearby, fast-evolving tidal disruption event AT2019qiz

At 66 Mpc, AT2019qiz is the closest optical tidal disruption event (TDE) to date, with a luminosity intermediate between the bulk of the population and the faint-and-fast event iPTF16fnl. Its

The tidal disruption event AT2017eqx: spectroscopic evolution from hydrogen rich to poor suggests an atmosphere and outflow

We present and analyse a new tidal disruption event (TDE), AT2017eqx at redshift z = 0.1089, discovered by Pan-STARRS and ATLAS. The position of the transient is consistent with the nucleus of its

Quasi-periodic flares from star-accretion-disc collisions

We present simulated results of quasi-periodic flares generated by the inelastic collisions of a star bound to a supermassive black hole and its attendant accretion disc. We show that the behaviour

Supermassive Black Holes at the Center of Galaxies

This was my final paper for the AST 308 Galaxies class at Michigan State University. Using many sources I was able to compile a moderate amount of information concerning the evidence for, and the

Star–disc interaction in galactic nuclei: orbits and rates of accreted stars

We examine the effect of an accretion disc on the orbits of stars in the central star cluster surrounding a central massive black hole by performing a suite of 39 high-accuracy direct N-body
