A flux-limited sample of dusty star-forming galaxies from the Atacama Cosmology Telescope: physical properties and the case for multiplicity
Kirsten R. Hall, Jake Hassan, Richard M. Feder +3
We report the modeling of the millimeter and far-infrared spectral energy distributions of 71 dusty star-forming galaxies (DSFGs) selected by the Atacama Cosmology Telescope (ACT)…
The Atacama Cosmology Telescope: Extragalactic Point Sources in the Southern Surveys at 150, 220 and 280 GHz observed between 2008-2010
Cristian Vargas, Carlos H. López-Caraballo, Elia S. Battistelli +18
We present a multi-frequency, multi-epoch catalog of extragalactic sources. The catalog is based on 150, 220, and 280 GHz observations carried out in 2008, 2009, and 2010 using the…
Quantifying the Thermal Sunyaev-Zel'dovich Effect and Excess Millimeter Emission in Quasar Environments
Kirsten R. Hall, Nadia L. Zakamska, Graeme Addison +23
In this paper we probe the hot, post-shock gas component of quasar-driven winds through the thermal Sunyaev-Zel'dovich (tSZ) effect. Combining datasets from the Atacama Cosmology T…
Accounting for selection bias using simulations: A general method and an application to millimeter-wavelength surveys
Megan B. Gralla, Tobias A. Marriage
We have developed a new Bayesian method to correct the flux densities of astronomical sources. The hybrid method combines a simulated likelihood to model survey selection together…
Atacama Cosmology Telescope: Dusty star-forming galaxies and active galactic nuclei in the equatorial survey
Megan B. Gralla, Tobias A. Marriage, Graeme Addison +30
We present a catalog of 510 radio-loud active galactic nuclei (AGN, primarily blazars) and 287 dusty star-forming galaxies (DSFGs) detected by the Atacama Cosmology Telescope at $>…
The Atacama Cosmology Telescope: CO(J = 3 - 2) mapping and lens modeling of an ACT-selected dusty star-forming galaxy
J. Rivera, A. J. Baker, P. A. Gallardo +13
We report Northern Extended Millimeter Array (NOEMA) CO() observations of the dusty star-forming galaxy ACT-S\,J020941+001557 at , which was detected as an u…
Downsizing of Star Formation Measured from the Clustered Infrared Background Correlated with Quasars
Kirsten R. Hall, Devin Crichton, Tobias Marriage +2
Powerful quasars can be seen out to large distances. As they reside in massive dark matter haloes, they provide a useful tracer of large scale structure. We stack Herschel-SPIRE im…
Multiwavelength characterisation of an ACT-selected, lensed dusty star-forming galaxy at z=2.64
G. W. Roberts-Borsani, M. J. Jiménez-Donaire, M. Daprà +19
We present \ci\,(2--1) and multi-transition CO observations of a dusty star-forming galaxy, ACT\,J2029+0120, which we spectroscopically confirm to lie at \,=\,2.64. We de…
On the redshift distribution and physical properties of ACT-selected DSFGs
T. Su, T. A. Marriage, V. Asboth +25
We present multi-wavelength detections of nine candidate gravitationally-lensed dusty star-forming galaxies (DSFGs) selected at 218GHz (1.4mm) from the ACT equatorial survey. Among…
Evidence for the Thermal Sunyaev-Zel'dovich Effect Associated with Quasar Feedback
Devin Crichton, Megan B. Gralla, Kirsten Hall +20
Using a radio-quiet subsample of the Sloan Digital Sky Survey spectroscopic quasar catalogue, spanning redshifts 0.5-3.5, we derive the mean millimetre and far-infrared quasar spec…
A giant radio halo in a low-mass SZ-selected galaxy cluster: ACT-CL J0256.5+0006
Kenda Knowles, Huib T. Intema, Andrew J. Baker +18
We present the detection of a giant radio halo (GRH) in the Sunyaev-Zel'dovich (SZ)-selected merging galaxy cluster ACT-CL J0256.5+0006 (), observed with the Giant Metre…
SALT spectroscopic observations of galaxy clusters detected by ACT and a Type II quasar hosted by a brightest cluster galaxy
Brian Kirk, Matt Hilton, Catherine Cress +20
We present Southern African Large Telescope (SALT) follow-up observations of seven massive clusters detected by the Atacama Cosmology Telescope (ACT) on the celestial equator using…
