Physics/Astronomy C290C Cosmology and Cosmology-BCCP Seminar
The Physics/Astronomy C290C series consists of the Cosmology-BCCP LBNL-Physics-Astronomy Cosmology seminars held Tuesdays 1:10-2:00 pm in room 131 Campbell Hall. Because this room is hard to keep clean, please don't bring your lunch (this is a change).
Please contact Joanne Cohn to add to this list or to suggest speakers.

Finding the First Cosmic Explosions
Primordial stars formed about 200 Myr after the Big Bang, ending the cosmic dark ages. They were the first great nucleosynthetic engines of the universe and may be the origins of the supermassive black holes (SMBHs) found in most massive galaxies today. In spite of their importance to the evolution of the early universe not much is known for certain about the properties of Pop III stars. But with the advent of JWST, Euclid, WFIRST and the ELTs it may soon be possible to directly observe their supernovae in the NIR and thus unambiguously constrain the properties of the first stars. I will present radiation hydrodynamical calculations of the light curves of the first SNe in the universe and discuss strategies for their detection. I will also describe how some high-z SNe may already have been found in surveys of galaxy cluster lenses such as CLASH and Frontier Fields. I will conclude my talk with new calculations of the evolution and collapse of supermassive primordial stars that constrain the masses of the first quasars at birth.

A cosmic web model of galaxy formation and some adventures in data visualization
The cosmic web is the stage where galaxy formation and evolution occurs. However, current models of galaxy formation ignore the effect of cosmic environment beyond basic descriptors and rely on crude approximations that do not capture the complex interplay between galaxies and their environment. In this talk I will discuss the Cosmic Web Detachment (CWD) model recently proposed to describe the effect of cosmic environment on galaxy formation and evolution. The CWD model can naturally reproduce a range of galaxy properties and provides a framework to interpret observations in a truly cosmological context.
During the talk I will make use of innovative visualization techniques including stereo 3D , 3D printing and natural interaction and discuss how data visualization can be used as a driver for scientific discovery.
