The role of supercluster filaments in shaping galaxy clusters
Raúl Baier-Soto, Yara Jaffé, Alexis Finoguenov +44
In a hierarchical CDM Universe, cosmic filaments serve as the primary channels for matter accretion into galaxy clusters, influencing the shape of their dark matter halos. We in…
Probing cosmic velocities with the pairwise kinematic Sunyaev-Zel'dovich signal in DESI Bright Galaxy Sample DR1 and ACT DR6
B. Hadzhiyska, Y. Gong, Y. Hsu +55
We present a measurement of the pairwise kinematic Sunyaev-Zel'dovich (kSZ) signal using the Dark Energy Spectroscopic Instrument (DESI) Bright Galaxy Sample (BGS) Data Release 1 (…
The Atacama Cosmology Telescope: Semi-Analytic Covariance Matrices for the DR6 CMB Power Spectra
Zachary Atkins, Zack Li, David Alonso +18
The Atacama Cosmology Telescope Data Release 6 (ACT DR6) power spectrum is expected to provide state-of-the-art cosmological constraints, with an associated need for precise error…
Miscentering of Optical Galaxy Clusters Based on Sunyaev-Zeldovich Counterparts
Jupiter Ding, Roohi Dalal, Tomomi Sunayama +7
The "miscentering effect," i.e., the offset between a galaxy cluster's optically-defined center and the center of its gravitational potential, is a significant systematic effect on…
Constraining cosmological parameters using the pairwise kinematic Sunyaev-Zel'dovich effect with CMB-S4 and future galaxy cluster surveys
E. Schiappucci, S. Raghunathan, C. To +8
We present a forecast of the pairwise kinematic Sunyaev-Zel'dovich (kSZ) measurement that will be achievable with the future CMB-S4 experiment. CMB-S4 is the next stage for ground-…
The Atacama Cosmology Telescope: Reionization kSZ trispectrum methodology and limits
Niall MacCrann, Frank J. Qu, Toshiya Namikawa +20
Patchy reionization generates kinematic Sunyaev-Zeldovich (kSZ) anisotropies in the cosmic microwave background (CMB). Large-scale velocity perturbations along the line of sight mo…
