Tracing the Interstellar Medium with [CII], [NII], and CO"

Thu, Apr 23, 2015 at 4:00 pm

1 LeConte Hall

Paul Goldsmith (JPL)

The [CII] 158um line is an important tracer of several critical stages of the evolution of the interstellar medium (ISM) and star formation. It has been widely observed in a large number of distant galaxies with Herschel and ALMA. But detailed observations of the [CII] line and other tracers in the local universe are a requirement for the interpretation of these observations of distant …

Star Formation and Molecular Gas in the First Three Billion Years

Thu, Apr 16, 2015 at 4:00 pm

1 LeConte Hall

Daniel Marrone (University of Arizona)

In the first few Gyr of cosmic history, the bulk of the stellar mass was assembled under conditions of higher density and lower metallicity than we observe locally. While the most advanced optical/IR facilities have provided very detailed studies of galaxies at z~2-5 and detections of rare galaxies at in the epoch of reionization, it continues to be extremely difficult to study the …

Gravitational Lensing of the Cosmic Microwave Background: Flux Conservation and Growth of Inhomogeneities

Tue, Apr 14, 2015

131A Campbell Hall

John Peacock (ROE)

Gravitational lensing is a rich source of cosmological information: it probes both the amplitude and evolution of metric fluctuations, plus the distance-redshift relation via the geometry of the distortion of background images. But in 2014, Clarkson et al. suggested that lensing had an average non-Newtonian "back-reaction" effect, which altered the effective distance to the CMB …

Binary Black Hole Accretion

Mon, Apr 13, 2015 at 12:00 pm

131A Campbell Hall

Andrew MacFadyen (NYU)

Binary black hole mergers in the presence of gaseous accretion flows are prime candidates for simultaneous observations of both gravitational waves and electromagnetic signals. I will present the results of 2D hydrodynamical simulations of circumbinary disk accretion using the moving-mesh code DISCO. These simulations demonstrate that gas accretion is not impeded by binarity. Gas is …

Pre-supernova Evolution and the Fates of Massive Stars

Thu, Apr 9, 2015 at 4:00 pm

1 LeConte Hall

Nathan Smith (University of Arizona)

A confluence of recent observations in the past decade have indicated that some basic assumptions that have guided our understanding of massive stars are not correct.  On the one hand, models for single massive star evolution seem to have overestimated the effects of mass loss through winds and the influence of rotation.  On the other hand, observations have shown that a large …

Total Lunar Eclipse - Saturday, April 4th

Sat, Apr 4, 2015, 3:15 am to 6:44 am

Space

From Alex Filippenko: There will be a lunar eclipse visible from much of North America before sunrise on the morning of Saturday, April 4 (this is, tonight -- Friday night). The Moon will start entering Earth's dark shadow ("umbra") at 3:15 am PDT and it will exit at 6:44 am PDT, just before sunrise (around 6:50 am PDT); totality will be at 4:48-5:03 am PDT, lasting only 5 …
