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 ...
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 ...
