The Morphologies and Outflow Kinematics of Star Formation Quenching
Alison Coil
11:00am|Bloomberg Hall Astrophysics Library
ABSTRACT: Since z=1 the number of quiescent, non-star forming galaxies in the Universe has roughly doubled. In order to constrain the star formation quenching mechanism, I will present results on the clustering properties, morphologies, and...

Cosmology and Astrophysics in the Planck Era
Bill Jones
11:00am|Bloomberg Hall Astrophysics Library

The Co-Evolution of Galaxies and Black Holes
Kevin Schawinski
11:00am|Bloomberg Hall Astrophysics Library
ABSTRACT: How, why and when are the scaling relationships between black holes set? Do accreting black holes really regulate the evolution of their host galaxies? What physical mechanisms underly feedback? I will discuss some recent results made...

A (Quantum) Field Theorist's Approach to Gravitational Dynamics
Rafael Porto
11:30am|Bloomberg Hall Astrophysics Library
ABSTRACT: The problem of motion in General Relativity has lost its academic status since the new generation of gravitational wave detectors relies upon an accurate description of the dynamics of inspiralling compact binaries. The main difficulty in...

A Bayesian Analysis of the Astrobiological Implications of the Rapid Emergence of Life on the Early Earth
Ed Turner
11:00am|Bloomberg Hall Astrophysics Library
ABSTRACT: Life arose on Earth sometime in the first few hundred million years after the young planet had cooled to the point that it could support water-based organisms on its surface. The early emergence of life on Earth has been taken as evidence...

The Dark Matter at the End of the Galaxy
Mariangela Lisanti
11:30am|Bloomberg Hall Astrophysics Library
ABSTRACT: Dark matter density profiles based upon ?CDM cosmology motivate an ansatz velocity distribution function with fewer high velocity particles than the Maxwell-Boltzmann distribution or proposed variants. The high velocity tail of the...

Galactic Enigmas in a Lambda-CDM Universe
11:00am|Bloomberg Hall Astrophysics Library
ABSTRACT: LCDM simulations successfully explain large-scale structure but appear to deviate from observations at small scales. Motivated by the local Universe, I will examine the dynamics of two so-called 'CDM crises' in detail and describe a...
