The Binarity of the Magellanic Clouds and the Formation of the Magellanic Stream
Gurtina Besla, Nitya Kallivayalil, Lars Hernquist +4
The HST proper motion (PM) measurements of the Clouds have severe implications for their interaction history with the Milky Way (MW) and with each other. The Clouds are likely on t…
A Semi-Analytic Model for the Co-evolution of Galaxies, Black Holes, and Active Galactic Nuclei
Rachel S. Somerville, Philip F. Hopkins, Thomas J. Cox +2
We present a new semi-analytic model that self-consistently traces the growth of supermassive black holes (BH) and their host galaxies within the context of the LCDM cosmological f…
Dissipation and the Fundamental Plane: Observational Tests
Philip F. Hopkins, Thomas J. Cox, Lars Hernquist
We develop observational tests of the idea that dissipation in gas-rich mergers produces the fundamental plane (FP) and related correlations obeyed by ellipticals. The FP 'tilt' im…
Dissipation and Extra Light in Galactic Nuclei: IV. Evolution in the Scaling Relations of Spheroids
Philip F. Hopkins, Lars Hernquist, Thomas J. Cox +2
We develop a model for the origins and redshift evolution of spheroid scaling relations. We consider spheroid sizes, velocity dispersions, masses, profile shapes (Sersic indices),…
Luminous Infrared Galaxies with the Submillimeter Array: I. Survey Overview and the Central Gas to Dust Ratio
Christine D. Wilson, Glen R. Petitpas, Daisuke Iono +14
We present new data obtained with the Submillimeter Array for a sample of fourteen nearby luminous and ultraluminous infrared galaxies. The galaxies were selected to have luminosit…
The Radical Consequences of Realistic Satellite Orbits for the Heating and Implied Merger Histories of Galactic Disks
Philip F. Hopkins, Lars Hernquist, Thomas J. Cox +2
Previous models of galactic disk heating in interactions invoke restrictive assumptions not necessarily valid in modern LCDM contexts: that satellites and orbits are rigid and circ…
