The RAdio Galaxy Environment Reference Survey (RAGERS): Evidence of an anisotropic distribution of submillimeter galaxies in the 4C 23.56 protocluster at z=2.48
Dazhi Zhou, Thomas R. Greve, Bitten Gullberg +41
High-redshift radio(-loud) galaxies (HRGs) are massive galaxies with powerful radio-loud active galactic nuclei (AGNs) and serve as beacons for protocluster identification. Howe…

Joyce N. Caliendo, Katherine E. Whitaker, Mohammad Akhshik +14
We present constraints on the dust continuum flux and inferred gas content of a gravitationally lensed massive quiescent galaxy at =1.8830.001 using AzTEC 1.1mm imaging wit…
AzTEC Survey of the Central Molecular Zone: Data Reduction, Analysis, and Preliminary Results
Yuping Tang, Q. Daniel Wang, Grant W. Wilson +14
We present a large-scale survey of the central molecular zone (CMZ) of our Galaxy, as well as a monitoring program of Sgr A*, with the AzTEC/Large Millimeter Telescope (LMT) in the…
A Radio-to-millimeter Census of Star-forming Galaxies in Protocluster 4C~23.56 at z = 2.5 : Global and local gas kinematics
Minju M. Lee, Ichi Tanaka, Ryohei Kawabe +12
We present a study of the gas kinematics of star-forming galaxies associated with protocluster 4C 23.56 at using resolution CO (4-3) data taken with ALMA. Eleven H…
AzTEC 1.1 mm observations of high-z protocluster environments: SMG overdensities and misalignment between AGN jets and SMG distribution
M. Zeballos, I. Aretxaga, D. H. Hughes +20
We present observations at 1.1 mm towards 16 powerful radio galaxies and a radio-quiet quasar at 0.5<z<6.3 acquired with the AzTEC camera mounted at the JCMT and ASTE to study the…
A dusty star-forming galaxy at z=6 revealed by strong gravitational lensing
Jorge A. Zavala, Alfredo Montaña, David H. Hughes +28
Since their discovery, submillimetre-selected galaxies (SMGs) have revolutionized the field of galaxy formation and evolution. From the hundreds of square degrees mapped at submill…
A radio-to-mm census of star-forming galaxies in protocluster 4C23.56 at z=2.5 : Gas mass and its fraction revealed with ALMA
Minju M. Lee, Ichi Tanaka, Ryohei Kawabe +18
We investigate gas contents of star-forming galaxies associated with protocluster 4C23.56 at z = 2.49 by using the redshifted CO(3-2) and 1.1 mm dust continuum with the Atacama Lar…
Early Science with the Large Millimeter Telescope: Detection of dust emission in multiple images of a normal galaxy at lensed by a Frontier Fields cluster
Alexandra Pope, Alfredo Montana, Andrew Battisti +32
We directly detect dust emission in an optically-detected, multiply-imaged galaxy lensed by the Frontier Fields cluster MACSJ0717.5+3745. We detect two images of the same galaxy at…
