LSST Observing Strategy White Paper: LSST Observations of WFIRST Deep Fields
R. J. Foley, A. M. Koekemoer, D. N. Spergel +38
The Wide-Field Infrared Survey Telescope (WFIRST) is expected to launch in the mid-2020s. With its wide-field near-infrared (NIR) camera, it will survey the sky to unprecedented de…
The effect of dark matter-dark radiation interactions on halo abundance -- a Press-Schechter approach
Omid Sameie, Andrew J. Benson, Laura V. Sales +3
We study halo mass functions with the Press-Schechter formalism for interacting dark matter models, where matter power spectra are damped due to dark acoustic oscillations in the e…
Quantifying the power spectrum of small-scale structure in semi-analytic galaxies
Sean Brennan, Andrew J. Benson, Francis-Yan Cyr-Racine +3
In the cold dark matter (CDM) picture of structure formation, galaxy mass distributions are predicted to have a considerable amount of structure on small scales. Strong gravitation…
Beyond subhalos: Probing the collective effect of the Universe's small-scale structure with gravitational lensing
Francis-Yan Cyr-Racine, Charles R. Keeton, Leonidas A. Moustakas
Gravitational lensing has emerged as a powerful probe of the matter distribution on subgalactic scales, which itself may contain important clues about the fundamental origins and p…
The WFIRST Exoplanet Microlensing Survey
David P. Bennett, Rachel Akeson, Jay Anderson +71
The Wide Field Infrared Survey Telescope (WFIRST) was the top ranked large space mission in the 2010 New Worlds, New Horizons decadal survey, and it was formed by merging the scien…
Unveiling the dynamical state of massive clusters through the ICL fraction
Y. Jiménez-Teja, R. Dupke, N. Benítez +34
We have selected a sample of eleven massive clusters of galaxies observed by the Hubble Space Telescope in order to study the impact of the dynamical state on the IntraCluster Ligh…
