Astro Seminars



Astronomy seminar; "Cosmology in the multi-messenger era"

Macarena Lagos (University of Chicago)
- David Rittenhouse Laboratory, A6

We have great certainty on how gravity works around our Solar System, but on large scales we still have a considerable lack of understanding about the constituents of our universe. Furthermore…

Past Astro Seminars



Astronomy seminar: "The Formation of Massive Galaxies: deep, high-redshift spectroscopy from the LEGA-C Survey and Beyond"

Rachel Bezanson (University of Pittsburgh)
- David Rittenhouse Laboratory, A6

Today’s massive elliptical galaxies are primarily red-and-dead, dispersion supported ellipticals. The physical process(es) driving the shutdown or “quenching” of star formation in these…



Astronomy seminar: "Evidence for CII diffuse line emission at redshift z~2.6"

Shengqi Yang (New York University)
- David Rittenhouse Laboratory, A2

CII is one of the brightest emission lines from star-forming galaxies and is an excellent tracer for star formation. Recent work measured the CII emission line amplitude for redshifts 2<z<3.2…



Special seminar on the recent Event Horizon Telescope results: "The Black Hole Shadow in M87"

Dan Marrone, University of Arizona
- David Rittenhouse Laboratory, A6

The Event Horizon Telescope (EHT) is an international collaboration to observe black holes at horizon-scale resolution. The EHT uses the technique of very long baseline interferometry (VLBI) and submillimeter…



Astronomy seminar: "Accretion in the Shadow of M87"

Joey Neilsen (Villanova University)
- David Rittenhouse Laboratory, A2

With the Event Horizon Telescope’s groundbreaking detection of the shadow of the supermassive black hole in M87, we have entered a new era of black hole astrophysics. After presenting the first results from the EHT,…



Astronomy seminar: "Integrated approach to cosmology"

Andrina Nicola (Princeton/ETH)
- David Rittenhouse Laboratory, A2

Recent progress in observational cosmology and the establishment of ΛCDM have relied on the combination of different cosmological probes. These probes are not independent, since they all measure the same physical…
