Active gas features in three HSC-SSP CAMIRA clusters revealed by high angular resolution analysis of MUSTANG-2 SZE and XXL X-ray observations

Nobuhiro Okabe, Simon Dicker, Dominique Eckert +33

We present results from simultaneous modeling of high angular resolution GBT/MUSTANG-2 90 GHz Sunyaev-Zel'dovich effect (SZE) measurements and XMM-XXL X-ray images of three rich ga…

Weak lensing Analysis of X-Ray-selected XXL Galaxy Groups and Clusters with Subaru HSC Data

Keiichi Umetsu, Mauro Sereno, Maggie Lieu +23

We present a weak-lensing analysis of X-ray galaxy groups and clusters selected from the XMM-XXL survey using the first-year data from the Hyper Suprime-Cam (HSC) Subaru Strategic…

The Richness-to-Mass Relation of CAMIRA Galaxy Clusters from Weak-lensing Magnification in the Subaru Hyper Suprime-Cam Survey

I-Non Chiu, Keiichi Umetsu, Ryoma Murata +2

We present a statistical weak-lensing magnification analysis on an optically selected sample of 3029 \texttt{CAMIRA} galaxy clusters with richness at redshift $0.2\leq z <1.…

Deep Multi-object Spectroscopy to Enhance Dark Energy Science from LSST

Jeffrey A. Newman, Jonathan Blazek, Nora Elisa Chisari +14

Community access to deep (i ~ 25), highly-multiplexed optical and near-infrared multi-object spectroscopy (MOS) on 8-40m telescopes would greatly improve measurements of cosmologic…

On the Assembly Bias of Cool Core Clusters Traced by H Nebulae

Elinor Medezinski, Michael McDonald, Surhud More +5

Do cool-core (CC) and noncool-core (NCC) clusters live in different environments? We make novel use of H emission lines in the central galaxies of redMaPPer clusters as proxies…
