Assembly Conformity of Structure Growth: Fossil versus Normal Groups of Galaxies
Zack Li, Renyue Cen
Using a semi-analytic method calibrated to the global star formation history and the stellar mass function at , we attempt to understand the most stellar deficient galaxy grou…
The Atacama Cosmology Telescope: A Measurement of the Cosmic Microwave Background Power Spectra at 98 and 150 GHz
Steve K. Choi, Matthew Hasselfield, Shuay-Pwu Patty Ho +136
We present the temperature and polarization angular power spectra of the CMB measured by the Atacama Cosmology Telescope (ACT) from 5400 deg of the 2013-2016 survey, which cove…
The Atacama Cosmology Telescope: DR4 Maps and Cosmological Parameters
Simone Aiola, Erminia Calabrese, Loïc Maurin +138
We present new arcminute-resolution maps of the Cosmic Microwave Background temperature and polarization anisotropy from the Atacama Cosmology Telescope, using data taken from 2013…
The cross correlation of the ABS and ACT maps
Zack Li, Sigurd Naess, Simone Aiola +29
One of the most important checks for systematic errors in CMB studies is the cross correlation of maps made by independent experiments. In this paper we report on the cross correla…
Constraining neutrino masses with weak-lensing multiscale peak counts
Virginia Ajani, Austin Peel, Valeria Pettorino +3
Massive neutrinos influence the background evolution of the Universe as well as the growth of structure. Being able to model this effect and constrain the sum of their masses is on…
