Galaxy bias in the era of LSST: perturbative bias expansions
Andrina Nicola, Boryana Hadzhiyska, Nathan Findlay +14
Upcoming imaging surveys will allow for high signal-to-noise measurements of galaxy clustering at small scales. In this work, we present the results of the LSST bias challenge, the…
WFIRST: The Essential Cosmology Space Observatory for the Coming Decade
O. Doré, C. Hirata, Y. Wang +46
Two decades after its discovery, cosmic acceleration remains the most profound mystery in cosmology and arguably in all of physics. Either the Universe is dominated by a form of da…
Illuminating the dark universe with a very high density galaxy redshift survey over a wide area
Yun Wang, Rachel Bean, Peter Behroozi +27
The nature of dark energy remains a profound mystery 20 years after the discovery of cosmic acceleration. A very high number density galaxy redshift survey over a wide area (HD GRS…
Searching for oscillations in the primordial power spectrum
P. Daniel Meerburg, David N. Spergel, Benjamin D. Wandelt
A small deviation from scale invariance in the form of oscillations in the primordial correlation spectra has been predicted by various cosmological models. In this paper we review…
Finding the Missing Baryons Using CMB as a Backlight
Shirley Ho, Simon Dedeo, David Spergel
We present a new method for detecting the missing baryons by generating a template for the kinematic Sunyaev-Zel'dovich effect. The template is computed from the product of a recon…
Galaxy Cluster Astrophysics and Cosmology: Questions and Opportunities for the Coming Decade
S. T. Myers, C. Pfrommer, J. Aguirre +21
We are learning much about how structure forms, in particular how clusters as nodes in the cosmic web evolve and accrete matter, and about the physical processes within these objec…
