E. Treister is an associate professor at the Institute for Astronomy of the Pontificia Universidad Catolica de Chile, and Investigador Asociado of the proposal. His research focuses on multiwavelength studies of the population of growing supermassive black holes. He led the previous Anillo program ACT1101 to explore black hole growth during galaxy mergers, which has strongly established that only the most luminous AGN are triggered by merger events. Through this Anillo, he further contributed very strongly to build up the current outreach program in Concepcion, with now up to 10.000 participants per year. He is an expert both on NuSTAR observations, in particular to probe strongly obscured AGN in the hard X-ray regime, as well as on sub-mm observations, to probe black hole accretion in AGN with ALMA. He is PI of the CATA area 1b on high energy astrophysics and supermassive black holes.

Main Expertise

Ezequiel Treister has probed the growth of supermassive black holes over cosmic history via X-ray and radio observations, including highly obscured sources. He also explored the role of galaxy mergers during the growth of supermassive black holes.
