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 …

In our modern understanding of galaxy formation, every galaxy forms within a dark matter
halo. The formation and growth of galaxies over time is connected to the growth of the halos …

We present pure spectroscopic constraints on the UV luminosity functions and cosmic star
formation rate (SFR) densities from 25 galaxies at z spec= 8.61–13.20. By reducing the …

ABSTRACT JWST observations have revealed a population of galaxies bright enough that
potentially challenge standard galaxy formation models in the Λ cold dark matter (ΛCDM) …

We present new measurements of rest-UV luminosity functions and angular correlation
functions from 4,100,221 galaxies at z∼ 2–7 identified in the Subaru/Hyper Suprime-Cam …

Numerical simulations have become one of the key tools used by theorists in all the fields of
astrophysics and cosmology. The development of modern tools that target the largest …

We use a new deprojection formula to infer the gravitational potential around isolated
galaxies from weak gravitational lensing. The results imply circular velocity curves that …

The evolution of the cluster mass function traces the growth of linear density perturbations,
providing valuable insights into the growth of structures, the nature of dark matter, and the …

Early observations with JWST indicate an overabundance of bright galaxies at redshifts z≳
10 relative to Hubble-calibrated model predictions. More puzzling still is the apparent lack of …

We present an updated version of the hmcode augmented halo model that can be used to
make accurate predictions of the non-linear matter power spectrum over a wide range of …
