[Physics-talks] Astronomy PASS talk on Monday

[Pooyan Goodarzi]

Hi all,

We will have a PASS talk by Marie on *Monday, May 5*. Please join us
at noon (from 12:00 pm to 1:00 pm) in the Nebula Room (PHYS 3027).


*Dr. Marie Wingyee Lau, PhD*
Monday, 12:00 pm, Nebula Room (PHYS 3027)
*Probing Quasar/Galaxy Evolution, Feeding, and Feedback: Extremely Red
Quasars (ERQs) and the Quasar-Associated Inflows Legacy Survey (QUAILS)*

My research focuses on understanding the evolution, feeding, and feedback
processes in quasar-host galaxies, particularly through extremely red
quasars (ERQs) and quasar-associated absorption lines. First, I study ERQs
at cosmic-noon redshifts. Using adaptive-optics integral-field
spectroscopy, I resolved their [OIII]5007 emission (Lau et al. 2022), while
wide-field integral-field observations revealed their extended Lyman-alpha
halos (Lau et al. 2024). Recently, we have identified candidates for even
fainter and redder quasars in photometric surveys and followed up with
spectroscopy to confirm. If you study dust-reddened quasar populations, I
welcome comparisons of selection techniques and characteristic properties.
Second, I have initiated a study of quasar-associated absorption lines at
intermediate to cosmic-noon redshifts. By measuring systemic redshifts of
the host galaxies using [OII]3727 and [OIII]5007 emission lines, I obtain
accurate relative velocities for the rest-frame UV associated absorbers. Of
particular interest are redshifted absorbers, which trace inflowing gas
onto quasar hosts. If you are interested in inflows, I would be happy to
discuss potential collaborations.
