    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...

    Uncovering the Signatures of Obscured AGN in Mergers

    Galaxy mergers have long been implicated as drivers of supermassive black hole (BH) and galaxy co-evolution, but the relative importance of mergers for fueling active galactic nuclei (AGN) is still uncertain. In large part, the ongoing debate stems from strong selection effects that are inherent to empirical studies of the merger/AGN connection. The most luminous AGN are often obscured by dust in late-stage mergers; infrared (IR) and hard X-ray selected AGN are much more likely to be hosted in...

    A Stochastic GW Background from Massive Black Hole Binaries

    Abstract:  I will present our models of MBH Binary (MBHB) evolution using the population of black holes and galaxies from the Illustris simulations.  Environmental hardening processes like dynamical friction and stellar scattering are required for most binaries to coalesce within a Hubble time.  These environmental effects reveal characteristic signatures on the resulting stochastic, Gravitational Wave Background (GWB).  Our recent results show the effects of both environment and eccentric evolution on...

    A Primordial Origin for Extrasolar Stellar Obliquity and its Role in Sculpting the Kepler Dichotomy

    ABSTRACT: The Solar System planets possess orbital planes differing by only a few degrees, inspiring the centuries-old hypothesis that planets form in disks, with the Sun's spin axes misaligned by a further 6 degrees. Only very recently has it been possible to observationally determine whether extrasolar planetary architectures typically share this coplanarity. Through analysis of planetary transit data, it has emerged that many, mostly hotter, stars hosting hot Jupiters possess...
