The Atacama Cosmology Telescope: Two-season ACTPol Extragalactic Point Sources and their Polarization properties
Rahul Datta, Simone Aiola, Steve K. Choi +30
We report on measurements of the polarization of extragalactic sources at 148 GHz made during the first two seasons of the Atacama Cosmology Telescope Polarization (ACTPol) survey.…
Measurement of the Splashback Feature around SZ-selected Galaxy Clusters with DES, SPT and ACT
T. Shin, S. Adhikari, E. J. Baxter +107
We present a detection of the splashback feature around galaxy clusters selected using their Sunyaev-Zel'dovich (SZ) signal. Recent measurements of the splashback feature around op…
Studies of Systematic Uncertainties for Simons Observatory: Detector Array Effects
Kevin T. Crowley, Sara M. Simon, Max Silva-Feaver +36
In this proceeding, we present studies of instrumental systematic effects for the Simons Obsevatory (SO) that are associated with the detector system and its interaction with the f…
The Simons Observatory: Instrument Overview
Nicholas Galitzki, Aamir Ali, Kam S. Arnold +75
The Simons Observatory (SO) will make precise temperature and polarization measurements of the cosmic microwave background (CMB) using a set of telescopes which will cover angular…
The Simons Observatory: Science goals and forecasts
The Simons Observatory Collaboration, Peter Ade, James Aguirre +247
The Simons Observatory (SO) is a new cosmic microwave background experiment being built on Cerro Toco in Chile, due to begin observations in the early 2020s. We describe the scient…
BoloCalc: a sensitivity calculator for the design of Simons Observatory
Charles A. Hill, Sarah Marie M. Bruno, Sara M. Simon +34
The Simons Observatory (SO) is an upcoming experiment that will study temperature and polarization fluctuations in the cosmic microwave background (CMB) from the Atacama Desert in…
Weak-Lensing Mass Calibration of ACTPol Sunyaev-Zel'dovich Clusters with the Hyper Suprime-Cam Survey
Hironao Miyatake, Nicholas Battaglia, Matt Hilton +57
We present weak-lensing measurements using the first-year data from the Hyper Suprime-Cam Strategic Survey Program on the Subaru telescope for eight galaxy clusters selected throug…
Neutrino masses and beyond-CDM cosmology with LSST and future CMB experiments
Siddharth Mishra-Sharma, David Alonso, Joanna Dunkley
Cosmological measurements over the next decade will enable us to shed light on the content and evolution of the Universe. Complementary measurements of the Cosmic Microwave Backgro…
The LiteBIRD Satellite Mission - Sub-Kelvin Instrument
A. Suzuki, P. A. R. Ade, Y. Akiba +149
Inflation is the leading theory of the first instant of the universe. Inflation, which postulates that the universe underwent a period of rapid expansion an instant after its birth…
