The SRG/eROSITA all-sky survey: Cosmology constraints from cluster abundances in the western Galactic hemisphere
V. Ghirardini, E. Bulbul, E. Artis +46
The cluster mass function traces the growth of linear density perturbations and provides valuable insights into the growth of structures, the nature of dark matter, and the cosmolo…
Hyper Suprime-Cam Year 3 Results: Cosmology from Cosmic Shear Power Spectra
Roohi Dalal, Xiangchong Li, Andrina Nicola +35
We measure weak lensing cosmic shear power spectra from the three-year galaxy shear catalog of the Hyper Suprime-Cam (HSC) Subaru Strategic Program imaging survey. The shear catalo…
Hyper Suprime-Cam Year 3 Results: Cosmology from Galaxy Clustering and Weak Lensing with HSC and SDSS using the Minimal Bias Model
Sunao Sugiyama, Hironao Miyatake, Surhud More +27
We present cosmological parameter constraints from a blind joint analysis of three two-point correlation functions measured from the Year 3 Hyper Suprime-Cam (HSC-Y3) imaging data,…
The eROSITA Final Equatorial-Depth Survey (eFEDS) -- Splashback radius of X-ray galaxy clusters using galaxies from HSC survey
Divya Rana, Surhud More, Hironao Miyatake +6
We present the splashback radius measurements around the SRG/eROSITA eFEDS X-ray selected galaxy clusters by cross-correlating them with HSC S19A photometric galaxies. The X-ray se…
EMPRESS. VIII. A New Determination of Primordial He Abundance with Extremely Metal-Poor Galaxies: A Suggestion of the Lepton Asymmetry and Implications for the Hubble Tension
Akinori Matsumoto, Masami Ouchi, Kimihiko Nakajima +42
The primordial He abundance is a powerful probe of cosmology. Currently, is best determined by observations of metal-poor galaxies, while there are on…
Interpreting the strongly lensed supernova iPTF16geu: time delay predictions, microlensing, and lensing rates
Anupreeta More, Sherry H. Suyu, Masamune Oguri +2
We present predictions for time delays between multiple images of the gravitationally lensed supernova, iPTF16geu, which was recently discovered from the intermediate Palomar Trans…
A new quadruple gravitational lens from the Hyper Suprime-Cam Survey: the puzzle of HSC~J115252+004733
Anupreeta More, Chien-Hsiu Lee, Masamune Oguri +16
We report the serendipitous discovery of a quadruply lensed source at , HSC~J115252+004733, from the Hyper Suprime-Cam (HSC) Survey. The source is lensed by an earl…
Passive galaxies as tracers of cluster environments at z~2
V. Strazzullo, E. Daddi, R. Gobat +18
Even 10 billion years ago, the cores of the first galaxy clusters are often found to host a characteristic population of massive galaxies with already suppressed star formation. He…
MOIRCS Deep Survey IV: Evolution of Galaxy Stellar Mass Function Back to z ~ 3
M. Kajisawa, T. Ichikawa, I. Tanaka +11
We use very deep near-infrared (NIR) imaging data obtained in MOIRCS Deep Survey (MODS) to investigate the evolution of the galaxy stellar mass function back to z~3. The MODS data…
MOIRCS Deep Survey III: Active Galactic Nuclei in Massive Galaxies at z=2-4
T. Yamada, M. Kajisawa, M. Akiyama +9
We investigate the X-ray properties of the K-band-selected galaxies at redshift 2 < z < 4 by using our deep near-infrared images obtained in the MOIRCS Deep Survey project and the…
Evidence of a link between the evolution of clusters and their AGN fraction
Caroline van Breukelen, Chris Simpson, Steve Rawlings +9
We discuss the optical properties, X-ray detections, and Active Galactic Nucleus (AGN) populations of four clusters at z ~ 1 in the Subaru-XMM Deep Field (SXDF). The velocity distr…
