Spitzer identifications and classifications of submillimeter galaxies in giant, high-redshift Lyman-alpha emission-line nebulae
(2007-01-20)
Using Spitzer Space Telescope IRAC (3.6-8um) and MIPS (24um) imaging, as well as Hubble Space Telescope optical observations, we identify the IRAC counterparts of the luminous power sources residing within the two largest ...
Restframe Optical Spectroscopic Classifications for Submillimeter Galaxies
(2006-11-10)
We report the results of a systematic near-infrared spectroscopic survey using the Subaru, VLT and Keck Telescopes of a sample of high redshift Ultra-luminous Infrared Galaxies (ULIRGs) mainly composed of submillimeter-selected ...
The Chandra Deep Protocluster Survey: Lyα Blobs are powered by heating, not cooling
(2009-07-20)
We present the results of a 400ks Chandra survey of 29 extended Ly-alpha emitting nebulae (Ly-alpha Blobs, LABs) in the z=3.09 proto-cluster in the SSA22 field. We detect luminous X-ray counterparts in five LABs, implying ...
A submm survey of Lyman-alpha haloes in the SA22 protocluster at z=3.1
(2005-09-30)
We present the results from a submm survey of a sample of 23 giant Lya emitting nebulae in the overdensity at z=3.09 in the SA22 field. These objects, which have become known as Lya Blobs (LABs) have a diverse range of ...
