NDRIO White Paper: Envisioning Digital Research Infrastructure for the Simons Observatory
Adam D. Hincks, Simone Aiola, J. Richard Bond +11
Observations of the cosmic microwave background (CMB) are an incredibly fertile source of information for studying the origins and evolution of the Universe. Canadian digital resea…
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…
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: Modeling the Gas Thermodynamics in BOSS CMASS galaxies from Kinematic and Thermal Sunyaev-Zel'dovich Measurements
Stefania Amodeo, Nicholas Battaglia, Emmanuel Schaan +52
The thermal and kinematic Sunyaev-Zel'dovich effects (tSZ, kSZ) probe the thermodynamic properties of the circumgalactic and intracluster medium (CGM and ICM) of galaxies, groups,…
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: Delensed Power Spectra and Parameters
Dongwon Han, Neelima Sehgal, Amanda MacInnis +39
We present LCDM cosmological parameter constraints obtained from delensed microwave background power spectra. Lensing maps from a subset of DR4 data from the Atacama Cosmology Tele…
