    Dark Matter Searches in Dwarf Galaxies

    Dwarf galaxies have long been considered a prime target in the search for a dark matter signal from the sky. I will discuss the current status of dark matter searches from dwarf galaxies and present results on the analysis of gamma-ray emission and dark matter content in recently discovered dwarf galaxies, including tests that are needed in order to test the hypothesis that any observed emission is due to a conventional astrophysical origin.

    Search for Intergalactic Magnetic Fields and Implications

     
    Abstract: The ongoing search for intergalactic magnetic fields using blazar observations suggests field strength in the 10^(-14) to 10^{-17} G range on tens of Mpc length scales. Such fields can have important implications for the early universe and also raises some puzzles.

    Challenges of Isotopic Molecular Observations

    Abstract: Isotopic ratios provide a powerful method to study the origin of elements and the chemical evolution of the Universe. Spectroscopic analysis is required for any remote astronomical source, with limits on angular resolution, sensitivity, and knowledge of the physical conditions. Molecular lines are particularly well suited as the spectral signatures of different isotopologues are well separated in frequency. I will overview the available spectroscopic observations of isotopic molecular substitutes involving D, 13C and 15N in...

    The Multi-Dimensional Core-Collapse Supernova Mechanism


    Abstract:  Core-collapse supernovae have challenged theorists and computational science for half a century. Such explosions are the source of many of the heavy elements in the Universe and the birthplace of neutron stars and stellar-mass black holes. However, determining the mechanism of explosion remains the key goal of theory. Recently, there have been breakthroughs in understanding and simulating these explosions, and I will describe our recent calculations that lead to robust...

    Accretion Dynamics in Pre-Main Sequence Binaries

    Protoplanetary disks are integral to the formation of low-mass stars and planets. A paradigm for the star-disk interaction has been extensively developed in the case of single stars. Most stars, however, form in binary or higher order systems where the distribution of disk material and mass flows are more complex. Short-period, pre-main sequence (pre-MS) binary stars can have up to three accretion disks: two circumstellar disks and a circumbinary disk separated by a dynamically cleared gap. Theory suggests that orbital motion may...
