Cosmological constraints from the angular power spectrum and bispectrum of luminous red galaxies and CMB lensing

Francesco Verdiani, Lea Harscouet, Matteo Zennaro +2

We study the projected clustering of photometric luminous red galaxies from the DESI Legacy Survey, combining their angular power spectrum, bispectrum, and cross-correlation with m…

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 relationship between galaxy size and halo properties: Insights from the IllustrisTNG simulations and differential clustering

Rachel S. Somerville, Austen Gabrielpillai, Boryana Hadzhiyska +1

The physical origin of the radial sizes of galaxies and how galaxy sizes are correlated with the properties of their host dark matter halos is an open question in galaxy formation.…

Refining local-type primordial non-Gaussianity: Sharpened constraints through bias expansion

Boryana Hadzhiyska, Simone Ferraro

Local-type primordial non-Gaussianity (PNG), predicted by many non-minimal models of inflation, creates a scale-dependent contribution to the power spectrum of large-scale structur…

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 DESI One-Percent Survey: Exploring the Halo Occupation Distribution of Luminous Red Galaxies and Quasi-Stellar Objects with AbacusSummit

Sihan Yuan, Hanyu Zhang, Ashley J. Ross +39

We present the first comprehensive Halo Occupation Distribution (HOD) analysis of the DESI One-Percent survey Luminous Red Galaxy (LRG) and Quasi-Stellar Object (QSO) samples. We c…
