Past Astro Seminars



Astronomy seminar: "A Modern View of Quasars in the LSST Era"

Gordon Richards (Drexel University)
- David Rittenhouse Laboratory, A6

A modern view of quasars sees them as diverse *processes* as opposed to the traditional view as more static *things*.  Such a picture is …



Astronomy seminar: "Exploring the Connection between Galaxies and their Supermassive Black Holes"

Vicki Sarajedini (Florida Atlantic University)
- David Rittenhouse Laboratory, A6

Active Galactic Nuclei (AGNs) are galaxies currently accreting significant amounts of material onto their central super massive black holes and may mark an important phase of galaxy evolution…



Astronomy seminar: "Lensing and Delensing: Results and Updates from BICEP/Keck and the South Pole Telescope"

Kimmy Wu (University of Chicago)
- David Rittenhouse Laboratory, A6

Gravitational lensing of the cosmic microwave background (CMB) encodes information from the low-redshift universe. Therefore, its measurement is useful for constraining cosmological parameters…



Astronomy seminar: "The Galaxy Star Formation Rate-Stellar Mass Correlation"

Eric Gawiser (Rutgers University)

Feb 5, 2020 - Feb 1, 2020 at - David Rittenhouse Laboratory, A6

A surprisingly tight correlation has been discovered between galaxies’ star formation rates (SFR) and stellar masses (M_*).  We show that the evolution of the normalization of the SFR-M_*…



Astronomy seminar: "Beyond optical depth: Future determination of ionization history from the CMB"

Duncan Watts (Johns Hopkins)
- David Rittenhouse Laboratory, A6

Cosmic microwave background (CMB) photons are partially polarized, both by free electrons around recombination, and by free electrons from reionization. The free electron fraction as a…
