A Millimetre Survey of Starburst Dominated Ultraluminous Infrared Galaxies at z~2
J. D. Younger, A. Omont, N. Fiolet +6
We present millimetre observations of a sample of 12 high redshift ultraluminous infrared galaxies (ULIRGs) in the Extended Growth Strip (EGS). These objects were initially selecte…
The Physical Scale of the Far-Infrared Emission in the Most Luminous Submillimeter Galaxies
Joshua D. Younger, Giovanni G. Fazio, David J. Wilner +10
We present high resolution submillimeter interferometric imaging of two of the brightest high-redshift submillimeter galaxies known: GN20 and AzTEC1 at 0.8 and 0.3 arcsec resolutio…
Spitzer IRAC Infrared Colours of Submillimetre-bright Galaxies
Min S. Yun, I. Aretxaga, M. L. N. Ashby +11
High-redshift submillimetre-bright galaxies identified by blank field surveys at millimetre and submillimetre wavelengths appear in the region of the IRAC colour-colour diagrams pr…
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…
How Do Disks Survive Mergers?
Philip F. Hopkins, Thomas J. Cox, Joshua D. Younger +1
We develop a physical model for how galactic disks survive and/or are destroyed in interactions. Based on dynamical arguments, we show gas primarily loses angular momentum to inter…
The Self-Regulated Growth of Supermassive Black Holes
Joshua D. Younger, Philip F. Hopkins, T. J. Cox +1
We present a series of simulations of the self--regulated growth of supermassive black holes (SMBHs) in galaxies via three different fueling mechanisms: major mergers, minor merger…
