The Atacama Cosmology Telescope: Dynamical masses for 44 SZ-selected galaxy clusters over 755 square degrees
Cristóbal Sifón, Nick Battaglia, Matthew Hasselfield +22
We present galaxy velocity dispersions and dynamical mass estimates for 44 galaxy clusters selected via the Sunyaev-Zel'dovich (SZ) effect by the Atacama Cosmology Telescope. Dynam…
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…
Designs for a large-aperture telescope to map the CMB 10X faster
Michael D. Niemack
Current large-aperture cosmic microwave background (CMB) telescopes have nearly maximized the number of detectors that can be illuminated while maintaining diffraction-limited imag…
Evidence for the kinematic Sunyaev-Zeľdovich effect with ACTPol and velocity reconstruction from BOSS
Emmanuel Schaan, Simone Ferraro, Mariana Vargas-Magaña +43
We use microwave temperature maps from two seasons of data from the Atacama Cosmology Telescope (ACTPol) at 146 GHz, together with the Constant Mass CMASS galaxy sample from the Ba…
Advanced ACTPol Cryogenic Detector Arrays and Readout
S. W. Henderson, R. Allison, J. Austermann +54
Advanced ACTPol is a polarization-sensitive upgrade for the 6 m aperture Atacama Cosmology Telescope (ACT), adding new frequencies and increasing sensitivity over the previous ACTP…
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…
