Tomographic galaxy clustering with the Subaru Hyper Suprime-Cam first year public data release
Andrina Nicola, David Alonso, Javier Sánchez +12
We analyze the clustering of galaxies in the first public data release of the HSC Subaru Strategic Program. Despite the relatively small footprints of the observed fields, the data…
The Atacama Cosmology Telescope: Component-separated maps of CMB temperature and the thermal Sunyaev-Zel'dovich effect
Mathew S. Madhavacheril, J. Colin Hill, Sigurd Naess +51
Optimal analyses of many signals in the cosmic microwave background (CMB) require map-level extraction of individual components in the microwave sky, rather than measurements at th…
Data compression in cosmology: A compressed likelihood for Planck data
Heather Prince, Jo Dunkley
We apply the massively optimized parameter estimation and data compression technique (MOPED) to the public Planck 2015 temperature likelihood, reducing the dimensions of the data s…
The Simons Observatory: Astro2020 Decadal Project Whitepaper
The Simons Observatory Collaboration, Maximilian H. Abitbol, Shunsuke Adachi +280
The Simons Observatory (SO) is a ground-based cosmic microwave background (CMB) experiment sited on Cerro Toco in the Atacama Desert in Chile that promises to provide breakthrough…
Quantifying the Thermal Sunyaev-Zel'dovich Effect and Excess Millimeter Emission in Quasar Environments
Kirsten R. Hall, Nadia L. Zakamska, Graeme Addison +23
In this paper we probe the hot, post-shock gas component of quasar-driven winds through the thermal Sunyaev-Zel'dovich (tSZ) effect. Combining datasets from the Atacama Cosmology T…
Removal of Galactic foregrounds for the Simons Observatory primordial gravitational wave search
Ben Thorne, Jo Dunkley, David Alonso +6
Upcoming observations from the Simons Observatory have been projected to constrain the tensor-to-scalar ratio, , at the level of 0.003. Here we describe one of the foreca…
Atacama Cosmology Telescope: Dusty star-forming galaxies and active galactic nuclei in the equatorial survey
Megan B. Gralla, Tobias A. Marriage, Graeme Addison +30
We present a catalog of 510 radio-loud active galactic nuclei (AGN, primarily blazars) and 287 dusty star-forming galaxies (DSFGs) detected by the Atacama Cosmology Telescope at $>…
Spectral Distortions of the CMB as a Probe of Inflation, Recombination, Structure Formation and Particle Physics
J. Chluba, A. Kogut, S. P. Patil +98
Following the pioneering observations with COBE in the early 1990s, studies of the cosmic microwave background (CMB) have focused on temperature and polarization anisotropies. CMB…
CDM or self-interacting neutrinos? - how CMB data can tell the two models apart
Minsu Park, Christina D. Kreisch, Jo Dunkley +2
Of the many proposed extensions to the CDM paradigm, a model in which neutrinos self-interact until close to the epoch of matter-radiation equality has been shown to provide a g…
Primordial Non-Gaussianity
P. Daniel Meerburg, Daniel Green, Muntazir Abidi +175
Our current understanding of the Universe is established through the pristine measurements of structure in the cosmic microwave background (CMB) and the distribution and shapes of…
Messengers from the Early Universe: Cosmic Neutrinos and Other Light Relics
Daniel Green, Mustafa A. Amin, Joel Meyers +136
The hot dense environment of the early universe is known to have produced large numbers of baryons, photons, and neutrinos. These extreme conditions may have also produced other lo…
