Astronomy Colloquium for 2017-09-27

Series: Astronomy Colloquium
Date: Wednesday 27-Sep-2017
Time: 16:05-17:00 (4:05-5:00 pm)
Location: ATL 2400
Speaker: Dr. Suvi Gezari (UMD)
Title: Exploring Supermassive Black Hole Demographics with Time Domain Observations

We are entering an era of increasingly powerful wide-field optical synoptic surveys that are transforming the study of the variable night sky. I will highlight the capability of time domain observations to study supermassive black holes (SMBHs), and in particular, to study their demographics (mass, spin, binarity). I will present our past results from the Pan-STARRS1 Medium Deep Survey and new results from the Intermediate Palomar Transient Factory that probe SMBHs in the nuclei of galaxies, including dormant SMBHs via the tidal disruption and accretion of a star, binary SMBHs via periodic quasar variability, and active SMBHs caught in the act of turning on. I will conclude with the exciting potential of the upcoming Zwicky Transient Facility and the Large Synoptic Survey Telescope to map the demographics of SMBHs over cosmic time.

Colloquia are usually preceded by espresso and ice cream at 1:45 pm outside room PSC 1150 and are followed by an informal reception at 5:15 pm in that room. Anyone interested in talking with the speaker, or being added to the colloquium announcement email list, should contact the colloquium organizer. Lunch will normally be reserved for the speaker to talk to graduate students.

Colloquium Organizer: Prof. L. Drake Deming
