An 80-kpc Lyman-alpha halo around a high redshift type-2 QSO
Daniel J. B. Smith, Matt J. Jarvis, Chris Simpson +1
We announce the discovery of an extended emission line region associated with a high redshift type-2 QSO. The halo, which was discovered in our new wide-field narrow-band survey, r…
Molecular Gas in a Submillimeter Galaxy at z=4.5: Evidence for a Major Merger at 1 Billion Years after the Big Bang
E. Schinnerer, C. L. Carilli, P. Capak +8
We report the detection of CO molecular line emission in the z=4.5 millimeter-detected galaxy COSMOS_J100054+023436 (hereafter: J100+0234) using the IRAM Plateau de Bure interferom…
Emission line activity in type 2 quasars from the Sloan Digital Sky Survey
Montse Villar-Martin, Andrew Humphrey, Alejo Martinez-Sansigre +3
We have compared the optical emission line ratios of type 2 quasars from Zakamska et al. with standard AGN photoionization model predictions, Seyfert 2s, HII galaxies, and narrow l…
Mid-infrared spectroscopy of high-redshift obscured quasars
Alejo Martinez-Sansigre, Mark Lacy, Anna Sajina +1
We present mid-infrared observations of 18 sources from a sample of 21 z~2 radio-intermediate obscured quasars. The mid-infrared spectra of the sources are continuum dominated, and…
Evidence for a Population of High-Redshift Submillimeter Galaxies from Interferometric Imaging
Joshua D. Younger, Giovanni G. Fazio, Jia-Sheng Huang +22
We have used the Submillimeter Array to image a flux limited sample of seven submillimeter galaxies, selected by the AzTEC camera on the JCMT at 1.1 mm, in the COSMOS field at 890u…
High-redshift obscured quasars
Alejo Martinez-Sansigre, Steve Rawlings
Using mid-infrared and radio criteria, we select a sample of candidate z~2 obscured quasars. Optical spectroscopy confirms about half of these as type-2 quasars, and modelling the…
