131 Campbell Hall

Leslie Rogers (UC Berkeley)
Tuomas Savolaien (Aalto University)
Eric Becklin (SOFIA)

The Department Lunch Talk series is a weekly event that features three 20 minute talks presented mainly by local scientists of any level to present their work to a broad spectrum of the department and usually includes one short talk by the astronomy colloquium speaker of the day.  Subjects can include personal scientific research, reporting on other work appearing in journals, education and public outreach efforts, science policy, and professional development issues.

The Masses, Densities, and Orbital Dynamics of Exoplanets

Wed, Apr 27, 2016 at 3:00 pm

131 Campbell Hall

Lauren Weiss (UC Berkeley)

We live in a golden era of exoplanet discovery and characterization. In the past few years, the Kepler Mission has discovered over 4000 exoplanets, enabling rich empirical studies of planet occurrence, composition, formation, and evolution. In particular, Kepler's 400 multi-planet systems represent the end-states of planet formation. Their orbital dynamics and planet compositions …

Post-Starburst Galaxies: Tracers of Galaxy Evolution and the Unlikely Hosts of Tidal Disruption Events

Tue, Apr 26, 2016 at 1:00 pm

131 Campbell Hall

K. Decker French (Arizona)

Post-starburst galaxies are in transition between star-forming galaxies and early-types, and represent a clear path for galaxies to transform from star-forming to quiescence. Many show signs of a recent galaxy-galaxy merger and a newly-evolved stellar bulge, and most have LINER-like emission, which may indicate low luminosity AGN activity. Thus, the study of this short-lived phase of galaxy …

Global Radiation MHD Simulations of Black Hole Accretion Disks

Thu, Apr 21, 2016 at 4:00 pm

1 LeConte Hall

Jim Stone (Princeton)

The inner regions of accretion flows in luminous sources such as AGN and X-ray binaries are radiation dominated.  In the case of AGN, radiation and winds produced by such flows are thought to be an important feedback mechanism during galaxy formation in massive halos.  I present new results from numerical studies of the magnetohydrodynamics of accretion this regime.  These …

Revisiting large scale structure analysis techniques in the DESI era

Tue, Apr 19, 2016 at 1:00 pm

131 Campbell Hall

Nikhil Padmanabhan (Yale)

Galaxy redshift surveys are powerful cosmological probes, and the next generations of these surveys, including DESI, Euclid and WFIRST, forecast sub-percent statistical errors on the expansion and growth rate of the Universe. I’ll aim to explore some of the analysis challenges that these surveys present, and possible approaches to address these. I’ll focus on two specific problems. …

The importance of being eccentric: stars and gas in the Galactic center

Thu, Apr 14, 2016 at 4:00 pm

1 LeConte Hall

Ann-Marie Madigan (UC Berkeley)

The center of our Galaxy is home to a supermassive black hole, SgrA*, and a nuclear star cluster a million times more dense than our local neighborhood. In this talk I will present the latest observations of the stars and gas clouds that live in this extreme environment. I’ll show how their surprising dynamics helps explain a wealth of observational data from event horizon scales all the …

Hunting for MaDCoWS: High Redshift Galaxy Clusters over the Full Extragalactic Sky

Tue, Apr 12, 2016 at 1:00 pm

131 Campbell Hall

Anthony Gonzalez (Florida)

The Massive and Distant Clusters of WISE Survey (MaDCoWS) is a comprehensive program to detect and characterize the most massive galaxy clusters at z~1 over the full extragalactic sky. I will give an overview of the survey and present recent results within the PanSTARRS footprint from our ongoing follow-up programs, including confirmation of the second most massive galaxy cluster known at …

Dark gas in the Diffuse Interstellar Medium

Thu, Apr 7, 2016 at 4:00 pm

131 Campbell Hall

Bill Reach (URSA)

The diffuse interstellar medium contains more molecular gas than had been appreciated before the discovery of "dark gas," which is evident when subtracting atomic gas from the total amount of material, presumed to be traced either by far-infrared dust thermal emission or gamma-rays from cosmic ray-nucleon interactions. Using the Planck far-infrared and Arecibo GALFA 21 cm line …
