Physics/Astronomy C290C Cosmology and Cosmology-BCCP Seminar
The Physics/Astronomy C290C series consists of the Cosmology-BCCP LBNL-Physics-Astronomy Cosmology seminars held Tuesdays 1:10-2:00 pm .
in room 131 Campbell Hall. . Please don't bring your lunch (it is hard to keep this room clean; this is a change).
Please mail Joanne Cohn to add to this list or to suggest speakers.

This seminar is intended for BCCP members and Berkeley graduate students pursuing their dissertation research in cosmology. Other LBL, Berkeley Astronomy and and Berkeley Physics Department members are welcome. If the talk is on ZOOM, members of the Berkeley Astronomy/Physics and Cosmology communities can email Joanne Cohn for information.

Speaker/Visitor Info is here.

Tracing the Growth and Evolution of Supermassive Black Holes with High-z Quasar Clustering Measurements
Quasar clustering measurements have always been a fundamental ingredient on which we build our understanding of supermassive black holes (SMBHs), their accretion history, and the co-evolution with their host galaxies/halos. Recently, thanks to the advent of the James Webb Space Telescope (JWST), we have pushed the study of quasar clustering well into the era of reionization: several JWST NIRCam-WFSS surveys are measuring the quasar-galaxy cross-correlation and galaxy-galaxy auto-correlation functions at z~6-7, providing a way to constrain the clustering of luminous quasars at these early epochs. Preliminary results from the EIGER surveys suggest that high-z quasars live in moderately strong overdensities, with a large correlation length that agrees well with the trend observed at z~2-4. In this talk, I will present a model that uses these clustering measurements (along with constraints on the luminosity functions) to jointly infer the properties of quasars and galaxies in the early Universe. The model builds on a new large-volume dark-matter-only cosmological simulation, FLAMINGO-10k, and returns key quantities such as the mass distribution of quasar/galaxy-hosting halos, the luminosity-halo mass relation for quasars and galaxies and their duty cycle/occupation fraction. I will discuss how these quantities can provide fundamental constraints to the evolution pathways of early SMBHs and galaxies, and examine the prospects for extending the model to connect results at different redshifts and include different probes of quasar activity. Finally, I will show how these results can help us contextualize the recent discovery of an abundant population of faint and/or obscured broad-line high-z AGN in JWST surveys.
