We present the survey design, implementation, and outlook for COSMOS-Web, a 255 hr
treasury program conducted by the James Webb Space Telescope in its first cycle of …

Quasars at cosmic dawn provide powerful probes of the formation and growth of the earliest
supermassive black holes (SMBHs) in the Universe, their connections to galaxy and …

Wide-field imaging and spectroscopy enable a host of astrophysical studies that range from
the largest cosmological scales to the local environment of the Milky Way. Starting in 2000 …

Abstract We implement Crossing Statistics to reconstruct in a model-agnostic manner the
expansion history of the universe and properties of dark energy, using DESI Data Release 1 …

The second data release of the LOFAR Two-Metre Sky Survey (LoTSS) covers 27% of the
northern sky, with a total area of~ 5700 deg 1. The high angular resolution of LOFAR with …

In the absence of numerous gravitational-wave detections with confirmed electromagnetic
counterparts, the" dark siren" method has emerged as a leading technique of gravitational …

Studies of the rest-frame ultraviolet (UV) luminosity functions (LFs) typically treat star-forming
galaxies and active galactic nuclei (AGNs) separately. However, modern ground-based …

We present the final data release of the Kilo-Degree Survey (KiDS-DR5), a public European
Southern Observatory (ESO) wide-field imaging survey optimised for weak gravitational …

The abundance of faint dwarf galaxies is determined by the underlying population of low-
mass dark matter (DM) halos and the efficiency of galaxy formation in these systems. Here …

We present the z≈ 6 type-1 quasar luminosity function (QLF), based on the Pan-STARRS1
(PS1) quasar survey. The PS1 sample includes 125 quasars at z≈ 5.7–6.2, with− 28≲ M …
