A high-significance detection of primordial tidal torque imprints

Ming-Jie Sheng, Hao-Ran Yu, Min Bao +8

Tidal-torque theory predicts that galaxy angular momenta are imprinted by the primordial tidal field acting on proto-structures and that they can retain information about the early…

Luminosity-Dependent Assembly Bias of Central Galaxies from Weak Lensing and Clustering

Zhenjie Liu, Hironao Miyatake, Joop Schaye +3

Assembly bias, which is the variation in halo clustering at fixed mass driven by formation history, has long been predicted by numerical simulations but remains difficult to confir…

Fuzzy dark matter simulations

Hsi-Yu Schive

Fuzzy dark matter (FDM), composed of ultralight bosons, exhibits intricate wave phenomena on galactic scales. Compared to cold dark matter, FDM simulations are significantly more c…

Evidence for Intrinsic Galaxy Alignments in Ellipticity Autocorrelations out to from SDSS Galaxies with DESI Imaging

Teppei Okumura

Measuring the autocorrelation of galaxy shapes, known as the intrinsic-intrinsic (II) correlation, is important for both cosmology and understanding the formation of massive ellipt…

CHEX-MATE: Cluster Multi-Probes in Three Dimensions (CLUMP-3D) II. Combined Gas and Dark Matter Analysis from X-ray, SZE, and WL

Adriana Gavidia, Junhan Kim, Jack Sayers +15

Under the standard model of hierarchical structure formation, the overall geometry of galaxy clusters is better described by a triaxial ellipse than a sphere. As a result, applying…

Simulating a Gaussian stochastic gravitational wave background signal in pulsar timing arrays

Reginald Christian Bernardo, Kin-Wang Ng

We revisit the theoretical modeling and simulation of a Gaussian stochastic gravitational wave background (SGWB) signal in a pulsar timing array (PTA). We show that the correlation…

Galaxy cluster count cosmology with simulation-based inference

M. Regamey, D. Eckert, R. Seppi +4

The abundance and mass distribution of galaxy clusters is a sensitive probe of cosmological parameters, through the sensitivity of the high-mass end of the halo mass function to $Ω…

Infalling ultra-faint dwarfs as emissaries of the Axiverse

A. Pozo, T. Broadhurst, H. N. Luu +8

Recent discoveries of ultra-faint dwarf galaxies (UFDs) infalling onto the Milky Way, namely Leo K \& M at kpc, considerably strengthens the case that UFDs constitute…

Probing dipolar power asymmetry with galaxy clustering and intrinsic alignments

Keita Minato, Atsushi Taruya, Teppei Okumura +1

We investigate the prospects for probing large-scale statistical anisotropy through galaxy clustering and intrinsic alignments (IA) in Stage IV galaxy surveys. Specifically, we con…

Robustness of pairwise kinematic Sunyaev-Zel'dovich effect to optical-cluster-selection bias

Y. -H. Hsu, D. Gruen, P. A. Gallardo +5

The pairwise kinematic Sunyaev-Zel'dovich(kSZ) effect measures both the pairwise motion between galaxy groups and clusters and the amount of gas within them, providing a tracer for…

TDCOSMO XVII. New time delays in 22 lensed quasars from optical monitoring with the ESO-VST 2.6m and MPG 2.2m telescopes

Frédéric Dux, Martin Millon, Aymeric Galan +29

We present new time delays, the main ingredient of time delay cosmography, for 22 lensed quasars resulting from high-cadence r-band monitoring on the 2.6 m ESO VLT Survey Telescope…
