About Me

I am an Assistant Professor in the Department of Astrophysical and Planetary Sciences at the University of Colorado, Boulder, where I work on observations of kpc-scale separation dual supermassive black holes in merger-remnant galaxies. These objects are observable when one or both of the supermassive black holes accrete gas as active galactic nuclei (AGN), in systems known as offset AGN and dual AGN, respectively. Offset AGN and dual AGN are valuable as tracers of galaxy evolution, including the role of mergers in building up black hole mass.

Here is my CV.

My Group:

Rebecca Nevin: Graduate student working on optical longslit observations of dual AGN candidates.

Scott Barrows: Postdoc working on Chandra and HST observations of offset AGN and dual AGN in galaxy mergers.

Francisco Müller-Sánchez: Postdoc working on VLA observations and spatially-resolved spectroscopy of dual AGN and AGN outflows.
