PKSB1740-517: An ALMA view of the cold gas feeding a distant interacting young radio galaxy
J. R. Allison, E. K. Mahony, V. A. Moss +12
Cold neutral gas is a key ingredient for growing the stellar and central black hole mass in galaxies throughout cosmic history. We have used the Atacama Large Millimetre Array (ALM…
Exploring cosmic origins with CORE: mitigation of systematic effects
P. Natoli, M. Ashdown, R. Banerji +123
We present an analysis of the main systematic effects that could impact the measurement of CMB polarization with the proposed CORE space mission. We employ timeline-to-map simulati…
Exploring Cosmic Origins with CORE: Survey requirements and mission design
J. Delabrouille, P. de Bernardis, F. R. Bouchet +200
Future observations of cosmic microwave background (CMB) polarisation have the potential to answer some of the most fundamental questions of modern physics and cosmology. In this p…
Exploring Cosmic Origins with CORE: The Instrument
P. de Bernardis, P. A. R. Ade, J. J. A. Baselmans +126
We describe a space-borne, multi-band, multi-beam polarimeter aiming at a precise and accurate measurement of the polarization of the Cosmic Microwave Background. The instrument is…
Exploring cosmic origins with CORE: effects of observer peculiar motion
C. Burigana, C. S. Carvalho, T. Trombetti +116
We discuss the effects on the CMB, CIB, and thermal SZ effect due to the peculiar motion of an observer with respect to the CMB rest frame, which induces boosting effects. We inves…
Exploring Cosmic Origins with CORE: B-mode Component Separation
M. Remazeilles, A. J. Banday, C. Baccigalupi +113
We demonstrate that, for the baseline design of the CORE satellite mission, the polarized foregrounds can be controlled at the level required to allow the detection of the primordi…
Exploring Cosmic Origins with CORE: Cluster Science
J. -B. Melin, A. Bonaldi, M. Remazeilles +118
We examine the cosmological constraints that can be achieved with a galaxy cluster survey with the future CORE space mission. Using realistic simulations of the millimeter sky, pro…
The Atacama Cosmology Telescope: Two-Season ACTPol Lensing Power Spectrum
Blake D. Sherwin, Alexander van Engelen, Neelima Sehgal +43
We report a measurement of the power spectrum of cosmic microwave background (CMB) lensing from two seasons of Atacama Cosmology Telescope Polarimeter (ACTPol) CMB data. The CMB le…
The Atacama Cosmology Telescope: Two-Season ACTPol Spectra and Parameters
Thibaut Louis, Emily Grace, Matthew Hasselfield +80
We present the temperature and polarization angular power spectra measured by the Atacama Cosmology Telescope Polarimeter (ACTPol). We analyze night-time data collected during 2013…
Exploring Cosmic Origins with CORE: Extragalactic sources in Cosmic Microwave Background maps
G. De Zotti, J. Gonzalez-Nuevo, M. Lopez-Caniego +121
We discuss the potential of a next generation space-borne Cosmic Microwave Background (CMB) experiment for studies of extragalactic sources. Our analysis has particular bearing on…
Future CMB tests of dark matter: ultra-light axions and massive neutrinos
Renée Hložek, David J. E. Marsh, Daniel Grin +3
Measurements of cosmic microwave background (CMB) anisotropies provide strong evidence for the existence of dark matter and dark energy. They can also test its composition, probing…
Spatial curvature endgame: Reaching the limit of curvature determination
C. Danielle Leonard, Philip Bull, Rupert Allison
Current constraints on spatial curvature show that it is dynamically negligible: (95% CL). Neglecting it as a cosmological parameter would b…
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…
Towards a cosmological neutrino mass detection
Rupert Allison, Paul Caucal, Erminia Calabrese +2
Future cosmological measurements should enable the sum of neutrino masses to be determined indirectly through their effects on the expansion rate of the Universe and the clustering…
Weak-Lensing Mass Calibration of the Atacama Cosmology Telescope Equatorial Sunyaev-Zeldovich Cluster Sample with the Canada-France-Hawaii Telescope Stripe 82 Survey
N. Battaglia, A. Leauthaud, H. Miyatake +39
Mass calibration uncertainty is the largest systematic effect for using clusters of galaxies to constrain cosmological parameters. We present weak lensing mass measurements from th…
Eliminating the optical depth nuisance from the CMB with 21 cm cosmology
Adrian Liu, Jonathan R. Pritchard, Rupert Allison +3
Amongst standard model parameters that are constrained by cosmic microwave background (CMB) observations, the optical depth stands out as a nuisance parameter. While provid…
Contamination of early-type galaxy alignments to galaxy lensing-CMB lensing cross-correlation
