ALMA Observations of Ly-alpha Blob 1: Halo Substructure Illuminated from Within
(2016-11-14)
We present new Atacama Large Millimeter/Submillimeter Array (ALMA) 850 μm continuum observations of the original Lyα Blob (LAB) in the SSA22 field at z = 3.1 (SSA22-LAB01). The ALMA map resolves the previously identified ...
ALMA observations of a z ≈ 3.1 protocluster : Star formation from active galactic nuclei and Lyman-alpha blobs in an overdense environment
(2016-09-21)
We exploit Atacama Large Interferometer Array (ALMA) 870 μm observations to measure the star formation rates (SFRs) of eight X-ray detected active galactic nuclei (AGNs) in a z ≈ 3.1 protocluster, four of which reside in ...
A resolved map of the infrared excess in a Lyman Break Galaxy at z=3
(2016-09-10)
We have observed the dust continuum of ten z=3.1 Lyman Break Galaxies with the Atacama Large Millimeter/Submillimeter Array at ~450 mas resolution in Band 7. We detect and resolve the 870um emission in one of the targets ...
Herschel protocluster survey : A search for dusty star-forming galaxies in protoclusters at z = 2-3
(2016-08-21)
We present a Herschel/Spectral and Photometric Imaging Receiver (SPIRE) survey of three protoclusters at z = 2-3 (2QZCluster, HS1700, SSA22). Based on the SPIRE colours (S350/S250 and S500/S350) of 250 μm sources, we ...
ALMA Deep Field in SSA22: A Concentration of Dusty Starbursts in a z = 3.09 Protocluster Core
(2015-12-04)
We report the results of 1farcm5 × 3' mapping at 1.1 mm with the Atacama Large Millimeter/submillimeter Array toward the central region of the z = 3.09 SSA22 protocluster. By combining our source catalog with archival ...
