Effects of a central dark matter core on time-delay cosmography with galaxy clusters

Yuting Liu, Masamune Oguri

The central dark matter distribution probes the nature of dark matter and baryon physics, yet its impact on time-delay cosmography is not fully explored. We update previous analyse…

Stacked strong and weak lensing united: Improved measurement of the stellar and dark matter distributions in massive early-type galaxies at

Momoka Fujikawa, Masamune Oguri

We present a new measurement of the stellar and dark matter distributions in massive early-type galaxies at redshift by combining stacked strong and weak lensing measur…

Generating the wide sequence of Diffuse Galaxies with de Broglie waves of Dark Matter

Jiashuo Zhang, Tom Broadhurst, Alvaro Pozo +9

Extensive Euclid satellite imaging at low surface brightness has revealed that most nearby galaxies are diffuse-looking spheroids, where the stellar radius increases for over three…

Weak-lensing Shear-Selected Galaxy Clusters from the Hyper Suprime-Cam Subaru Strategic Program: III. A precision cosmological sample enabled by optical confirmation

I-Non Chiu, Kai-Feng Chen, Masamune Oguri +9

We develop fCAMIRA (forced-mode CAMIRA), a tool for optical cluster confirmation, and apply it to a sample of 129 weak-lensing (WL) shear-selected galaxy clusters identified in ape…

Strong Stellar Diffusion from Wave DM Cosmological Simulation and Potential Unified Origin for dSphs, UFGs, and UDGs

A. Pozo, T. Broadhurst, J. Zhang +6

Our DM simulations predict that stars diffuse throughout dark matter halos over the Hubble time through a random walk driven by the wave perturbations intrinsic to DM. The re…

XMM-Newton observations of ten high-redshift CAMIRA clusters of galaxies

Naomi Ota, Ikuyuki Mitsuishi, Nobuhiro Okabe +9

We present results from XMM-Newton observations of ten high-redshift () galaxy clusters selected from the CAMIRA catalog based on high richness (). These m…
