Splashback radius of nonspherical dark matter halos from cosmic density and velocity fields
Teppei Okumura, Takahiro Nishimichi, Keiichi Umetsu +1
We investigate the splashback features of dark-matter halos based on cosmic density and velocity fields. Besides the density correlation function binned by the halo orientation ang…
The Projected Dark and Baryonic Ellipsoidal Structure of 20 CLASH Galaxy Clusters
Keiichi Umetsu, Mauro Sereno, Sut-Ieng Tam +24
We reconstruct the two-dimensional (2D) matter distributions in 20 high-mass galaxy clusters selected from the CLASH survey by using the new approach of performing a joint weak len…
Cosmological distance indicators
Sherry H. Suyu, Tzu-Ching Chang, Frédéric Courbin +1
We review three distance measurement techniques beyond the local universe: (1) gravitational lens time delays, (2) baryon acoustic oscillation (BAO), and (3) HI intensity mapping.…
