Matthew Temple

Astronomer and astrophysicist researching
supermassive black holes and their host galaxies.

From April 2022, I am a FONDECYT Research Fellow at the Universidad Diego Portales in Santiago, Chile, working with Roberto Assef and Claudio Ricci. My research explores how quasars and active galactic nuclei are powered by accretion onto supermassive black holes, and how they can feed back energy into their host galaxies. I obtained my Ph.D. from the Institute of Astronomy at the University of Cambridge, UK, working with Manda Banerji and Paul Hewett.

Research Interests

Quasars - AGN Outflows - SMBH/Galaxy Coevolution - Line Emission & Atomic Physics - Large Surveys

My research seeks to understand how supermassive black holes grow and evolve in conjunction with their host galaxies. I use wide-field spectroscopic and photometric surveys to find and study accreting black holes at all epochs, from quasars at high redshift to active galaxies in the local universe. By comparing the emission lines seen in quasar spectra with predictions from photoionization models, I look to constrain the structure and geometry of the ionized gas which surrounds supermassive black holes. I also enjoy investigating interesting and unusual populations of active galaxies using multi-wavelength observations, to better understand the interplay between black hole accretion, AGN-driven outflows and star formation across the past 12.5 billion years of cosmic history.
