Princeton University Galread [Galactic/Extragalactic Reading Group]

A dominant population of optically invisible massive galaxies in the early Universe

Discussion Leader: Sinclaire Manning

11:00am|Remote via Zoom

Each week, we hold a relatively informal seminar/discussion series with an emphasis on extra-galactic and large-scale structure astrophysics.

During Galread a leader/visitor presents a recent paper to the discussion group. The PDF of the paper is...

Constraining the Circumbinary Disk Tilt in the KH 15D system

Michael Poon

12:15pm|Virtual Meeting

KH 15D is a system which consists of a young, eccentric, eclipsing binary, and a circumbinary disk which obscures the binary as the disk precesses. We develop a self-consistent model that provides a reasonable fit to the photometric variability that...

The Merger History of Elliptical Galaxies: Mass Deficit

Fani Dosopoulou

12:30pm|via ZOOM

Abstract: The structure and kinematics of galactic nuclei are fossil relics of the merger histories of galaxies and of the interaction between stars and SMBH binaries. Stars ejection during the SMBH binary evolution should reduce a galaxy’s central...

Galaxy Clusters : the largest particle accelerators in the Universe

Gianfranco Brunetti

11:00am|Virtual Meeting

Galaxy clusters and cosmic filaments are the largest structures in the Universe. During mergers between clusters shocks and turbulence are driven in the intra-cluster-medium (ICM) and dissipate a fraction of their energy into particle acceleration...
