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...
