MERGHERS Pilot: MeerKAT discovery of diffuse emission in nine massive Sunyaev-Zel'dovich-selected galaxy clusters from ACT
K. Knowles, D. S. Pillay, S. Amodeo +26
The MeerKAT Exploration of Relics, Giant Halos, and Extragalactic Radio Sources (MERGHERS) survey is a planned project to study a large statistical sample of galaxy clusters with t…
The Atacama Cosmology Telescope: Detection of mm-wave transient sources
Sigurd Naess, Nick Battaglia, J. Richard Bond +29
We report on the serendipitous discovery of three transient mm-wave sources using data from the Atacama Cosmology Telescope. The first, detected at RA = 273.8138, dec = -49.4628 at…
The Atacama Cosmology Telescope: Weighing distant clusters with the most ancient light
Mathew S. Madhavacheril, Cristóbal Sifón, Nicholas Battaglia +58
We use gravitational lensing of the cosmic microwave background (CMB) to measure the mass of the most distant blindly-selected sample of galaxy clusters on which a lensing measurem…
Fast computation of angular power spectra and covariances of high-resolution cosmic microwave background maps using the Toeplitz approximation
Thibaut Louis, Sigurd Naess, Xavier Garrido +1
We present a simple approximation that can speed up the computation of the mode-coupling matrices, which are usually the bottleneck for computing unbiased angular power spectra, as…
The Atacama Cosmology Telescope: A Catalog of > 4000 Sunyaev-Zel'dovich Galaxy Clusters
M. Hilton, C. Sifón, S. Naess +146
We present a catalog of 4195 optically confirmed Sunyaev-Zel'dovich (SZ) selected galaxy clusters detected with signal-to-noise > 4 in 13,211 deg of sky surveyed by the Atacama…
The Atacama Cosmology Telescope: Combined kinematic and thermal Sunyaev-Zel'dovich measurements from BOSS CMASS and LOWZ halos
Emmanuel Schaan, Simone Ferraro, Stefania Amodeo +55
The scattering of cosmic microwave background (CMB) photons off the free-electron gas in galaxies and clusters leaves detectable imprints on high resolution CMB maps: the thermal a…
The Atacama Cosmology Telescope: DR5 maps of 18,000 square degrees of the microwave sky from ACT 2008-2018 data
Sigurd Naess, Simone Aiola, Jason E. Austermann +59
This paper presents a maximum-likelihood algorithm for combining sky maps with disparate sky coverage, angular resolution and spatially varying anisotropic noise into a single map…
The Atacama Cosmology Telescope: A CMB lensing mass map over 2100 square degrees of sky and its cross-correlation with BOSS-CMASS galaxies
Omar Darwish, Mathew S. Madhavacheril, Blake Sherwin +50
We construct cosmic microwave background lensing mass maps using data from the 2014 and 2015 seasons of observations with the Atacama Cosmology Telescope (ACT). These maps cover 21…
CMB-HD: Astro2020 RFI Response
Neelima Sehgal, Simone Aiola, Yashar Akrami +45
CMB-HD is a proposed ultra-deep (0.5 uk-arcmin), high-resolution (15 arcseconds) millimeter-wave survey over half the sky that would answer many outstanding questions in both funda…
The cross correlation of the ABS and ACT maps
Zack Li, Sigurd Naess, Simone Aiola +29
One of the most important checks for systematic errors in CMB studies is the cross correlation of maps made by independent experiments. In this paper we report on the cross correla…
The Atacama Cosmology Telescope: Constraints on Cosmic Birefringence
Toshiya Namikawa, Yilun Guan, Omar Darwish +51
We present new constraints on anisotropic birefringence of the cosmic microwave background polarization using two seasons of data from the Atacama Cosmology Telescope covering $456…
