Extensions to the halo occupation distribution model for more accurate clustering predictions

Esteban Jiménez, Sergio Contreras, Nelson Padilla +3

We test different implementations of the halo occupation distribution (HOD) model to reconstruct the spatial distribution of galaxies as predicted by a publicly available semi-anal…

Mass Variance from Archival X-ray Properties of Dark Energy Survey Year-1 Galaxy Clusters

A. Farahi, X. Chen, A. E. Evrard +76

Using archival X-ray observations and a log-normal population model, we estimate constraints on the intrinsic scatter in halo mass at fixed optical richness for a galaxy cluster sa…

Primordial Black Holes from Thermal Inflation

Konstantinos Dimopoulos, Tommi Markkanen, Antonio Racioppi +1

We present a novel mechanism for the production of primordial black holes (PBHs). The mechanism is based on a period of thermal inflation followed by fast-roll inflation due to tac…

Stellar mass as a galaxy cluster mass proxy: application to the Dark Energy Survey redMaPPer clusters

A. Palmese, J. Annis, J. Burgad +82

We introduce a galaxy cluster mass observable, , based on the stellar masses of cluster members, and we present results for the Dark Energy Survey (DES) Year 1 observation…

Dark Energy Survey Year 1 Results: Calibration of Cluster Mis-centering in the redMaPPer Catalogs

Y. Zhang, T. Jeltema, D. L. Hollowood +83

The center determination of a galaxy cluster from an optical cluster finding algorithm can be offset from theoretical prescriptions or -body definitions of its host halo center.…
