The recent result of the Dark Energy Spectroscopic Instrument (DESI) in combination with
other cosmological data shows evidence of the evolving dark energy parametrized by the w …

The hydrogen 21-cm signal is predicted to be the richest probe of the young Universe,
including those eras known as the cosmic Dark Ages, the Cosmic Dawn (when the first star …

Abstract The One-Percent survey of the Dark Energy Spectroscopic Instrument collected∼
270k emission line galaxies (ELGs) at 0.8< z< 1.6. The high completeness of the sample …

We present AstroCLIP, a strategy to facilitate the construction of astronomical foundation
models that bridge the gap between diverse observational modalities. We demonstrate that …

Lyman break galaxies (LBGs) are promising probes for clustering measurements at high
redshift, z> 2, a region only covered so far by Lyman-α forest measurements. In this paper …

In this paper, we present the estimation of systematics related to the halo occupation
distribution (HOD) modeling in the baryon acoustic oscillations (BAO) distance …

In the era of precision cosmology, ensuring the integrity of data analysis through blinding
techniques is paramount--a challenge particularly relevant for the Dark Energy …

We present a computationally efficient galaxy archetype-based redshift estimation and
spectral classification method for the Dark Energy Survey Instrument (DESI) survey. The …

The recurrent activity of radio AGN, with phases of activity alternating with periods of
quiescence, has been known since the early studies of these objects. The full relevance of …

We present constraints on the dark scattering model through cosmic shear measurements
from the Kilo Degree Survey (KiDS-1000), using an accelerated pipeline with novel …
