One Halo, Two Boundaries: Relating Accretion Shocks and Splashback Radii in Galaxy Clusters
Siddhant Sen, Susmita Adhikari, Daisuke Nagai +1
The boundaries of dark matter and gas in clusters are delineated by the splashback radius and the accretion shock, respectively. Theoretically, both of these boundaries are expecte…
Protohalos and their connection to halo assembly, shape and structure
Farnik Nikakhtar, Daisuke Nagai, Marcello Musso +1
Protohalos, primordial regions in the initial cosmic density field that evolve into dark matter halos, are crucial for understanding cosmic structure formation. Motivated by the po…
Baryon Pasting the Uchuu Lightcone Simulation
Erwin T. Lau, Daisuke Nagai, Arya Farahi +4
We present the Baryon Pasted (BP) X-ray and thermal Sunyaev-Zel'dovich (tSZ) maps derived from the half-sky Uchuu Lightcone simulation. These BP-Uchuu maps are constructed using mo…
Cosmology and Astrophysics with the Diffuse eRASS1 X-ray Angular Power Spectrum
Erwin T. Lau, Ákos Bogdán, Daisuke Nagai +2
The recent tension in the value of the cosmological parameter , which represents the amplitude of the matter density fluctuations of the universe, ha…
Masses of Sunyaev-Zel'dovich Galaxy Clusters Detected by The Atacama Cosmology Telescope: Stacked Lensing Measurements with Subaru HSC Year 3 data
Masato Shirasaki, Cristóbal Sifón, Hironao Miyatake +13
We present a stacked lensing analysis of 96 galaxy clusters selected by the thermal Sunyaev-Zel'dovich (SZ) effect in maps of the cosmic microwave background (CMB). We select foreg…
ICM-SHOX. Paper I: Methodology overview and discovery of a gas--dark matter velocity decoupling in the MACS J0018.5+1626 merger
Emily M. Silich, Elena Bellomi, Jack Sayers +12
Galaxy cluster mergers are rich sources of information to test cluster astrophysics and cosmology. However, cluster mergers produce complex projected signals that are difficult to…
