Multi-Phenomena Modeling of the New Bullet Cluster, ZwCl008.8+52, using N-body/hydrodynamical Simulations
Sandor M. Molnar, Tom Broadhurst
We use hydrodynamical/N-body simulations to interpret the newly discovered Bullet-cluster-like merging cluster, ZwCl 0008.8+5215 (ZwCl 0008 hereafter), where a dramatic collision i…
Strong orientation dependence of surface mass density profiles of dark haloes at large scales
Ken Osato, Takahiro Nishimichi, Masamune Oguri +2
We study the dependence of surface mass density profiles, which can be directly measured by weak gravitational lensing, on the orientation of haloes with respect to the line-of-sig…
H0LiCOW VIII. A weak lensing measurement of the external convergence in the field of the lensed quasar HE04351223
O. Tihhonova, F. Courbin, D. Harvey +10
We present a weak gravitational lensing measurement of the external convergence along the line of sight to the quadruply lensed quasar HE04351223. Using deep r-band images f…
Galaxy Kinematics and Mass Calibration in Massive SZE Selected Galaxy Clusters to z=1.3
R. Capasso, A. Saro, J. J. Mohr +27
The galaxy phase-space distribution in galaxy clusters provides insights into the formation and evolution of cluster galaxies, and it can also be used to measure cluster mass profi…
Growing a `Cosmic Beast': Observations and Simulations of MACS J0717.5+3745
M. Jauzac, D. Eckert, M. Schaller +18
We present a gravitational lensing and X-ray analysis of a massive galaxy cluster and its surroundings. The core of MACS\,J0717.5+3745 (\,$10^{15}…
Baryon Content in a Sample of 91 Galaxy Clusters Selected by the South Pole Telescope at 0.2 < z < 1.25
I. Chiu, J. J. Mohr, M. McDonald +89
We estimate total mass (), intracluster medium (ICM) mass () and stellar mass () in a Sunyaev-Zel'dovich effect (SZE) selected sample of 91 ga…
Lack of clustering in low-redshift 21-cm intensity maps cross-correlated with 2dF galaxy densities
C. J. Anderson, N. J. Luciw, Y. -C. Li +13
We report results from 21-cm intensity maps acquired from the Parkes radio telescope and cross-correlated with galaxy maps from the 2dF galaxy survey. The data span the redshift ra…
First results on the cluster galaxy population from the Subaru Hyper Suprime-Cam survey. II. Faint end color-magnitude diagrams and radial profiles of red and blue galaxies at
Atsushi J. Nishizawa, Masamue Oguri, Taira Oogi +16
We present a statistical study of the redshift evolution of the cluster galaxy population over a wide redshift range from 0.1 to 1.1, using optically-selected CAMIRA cl…
Large-scale structure in mimetic Horndeski gravity
Frederico Arroja, Teppei Okumura, Nicola Bartolo +2
In this paper, we propose to use the mimetic Horndeski model as a model for the dark universe. Both cold dark matter (CDM) and dark energy (DE) phenomena are described by a single…
Intrinsic Alignments and Splashback Radius of Dark Matter Halos from Cosmic Density and Velocity Fields
Teppei Okumura, Takahiro Nishimichi, Keiichi Umetsu +1
We investigate the effects of intrinsic alignments (IA) of dark-matter halo shapes on cosmic density and velocity fields from cluster to cosmic scales beyond 100 Mpc/h. Besides the…
Probing supervoids with weak lensing
Yuichi Higuchi, Kaiki Taro Inoue
The cosmic microwave background (CMB) has non-Gaussian features in the temperature fluctuations. An anomalous cold spot surrounded with a hot ring, called the Cold Spot is one of s…
Search for CII Emission on Cosmological Scales at Redshift Z~2.6
Anthony R. Pullen, Paolo Serra, Tzu-Ching Chang +2
We present a search for CII emission over cosmological scales at high-redshifts. The CII line is a prime candidate to be a tracer of star formation over large-scale structure since…
MACS J0416.1-2403: Impact of line-of-sight structures on strong gravitational lensing modelling of galaxy clusters
G. Chirivì, S. H. Suyu, C. Grillo +5
Exploiting the powerful tool of strong gravitational lensing by galaxy clusters to study the highest-redshift Universe and cluster mass distributions relies on precise lens mass mo…
