The Precision Array to Probe the Epoch of Reionization (PAPER) is one of several intensity mapping experiments aiming to use redshifted 21cm emission to study our early universe. PAPER is deployed in South Africa, and combines inexpensive...

ABSTRACT: I will present an analysis of the SEEDS direct imaging survey for young, self-luminous exoplanets at large separations from their host stars. I will discuss the survey design and sensitivity, image processing, the selection of imaging...

Although intrinsically dark, a black hole can potentially act as a battery in an electromagnetic circuit with a neutron star – a battery that can potential power great luminosities.

I describe my preliminary results in calculating the extragalactic backgrounds from star-forming galaxies at all energies. First, I construct very simple models of galaxies using relations like the Schmidt law. This lets me estimate quantities...

The Large Synoptic Survey Telescope is a large-aperture, wide-field, ground-based telescope designed to take deep images of the entire southern sky in six optical colors every few nights. The resulting database can be used to address a wide variety...

ABSTRACT: The Cosmic Microwave Background Radiation is our most important source of information about the early universe. Many of its features are in good agreement with the predictions of the so-called standard model of cosmology -- the Lambda Cold...
