HST Morphologies of z~2 Dust Obscured Galaxies I: Power-law Sources
R. S. Bussmann, Arjun Dey, J. Lotz +12
We present high spatial resolution optical and near-infrared imaging obtained using the ACS, WFPC2 and NICMOS cameras aboard the Hubble Space Telescope of 31 24um--bright z~2 Dust…
Disk Evolution and Bar Triggering Driven by Interactions with Dark Matter Substructure
Emilio Romano-Diaz, Isaac Shlosman, Clayton Heller +1
We study formation and evolution of bar-disk systems in fully self-consistent cosmological simulations of galaxy formation in the LCDM WMAP3 Universe. In a representative model we…
Erasing Dark Matter Cusps in Cosmological Galactic Halos with Baryons
Emilio Romano-Diaz, Isaac Shlosman, Yehuda Hoffman +1
We study the central dark matter (DM) cusp evolution in cosmological galactic halos. Models with and without baryons (baryons+DM, hereafter BDM model, and pure DM, PDM model, respe…
A 500 kpc HI Extension of the Virgo Pair NGC4532/DDO137 Detected by the Arecibo Legacy Fast ALFA (ALFALFA) Survey
R. A. Koopmann, R. Giovanelli, M. P. Haynes +6
We report the discovery of a ~500 kpc HI extension southwest of the Virgo Cluster HI-rich pair NGC 4532/DDO 137, detected as part of the Arecibo Legacy Fast ALFA (ALFALFA) Survey.…
Radio continuum imaging of the R CrA star-forming region with the ATCA
O. Miettinen, S. Kontinen, J. Harju +1
The aim of this study is to investigate the nature of radio sources associated with young stellar objects (YSOs) belonging to the R CrA cluster. By combining the centimetre radio d…
A Significant Population of Very Luminous Dust-Obscured Galaxies at Redshift z ~ 2
Arjun Dey, B. T. Soifer, Vandana Desai +12
Observations with Spitzer Space Telescope have recently revealed a significant population of high-redshift z~2 dust-obscured galaxies (DOGs) with large mid-IR to UV luminosity rati…
