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 …

Ultra-light dark matter is a class of dark matter models (DM), where DM is composed by
bosons with masses ranging from 10^-24\, eV< m< eV 10-24 eV< m< eV. These models …

Galaxies with stellar masses as high as roughly 1011 solar masses have been identified,–
out to redshifts z of roughly 6, around 1 billion years after the Big Bang. It has been difficult to …

One of the main goals of the JWST is to study the first galaxies in the Universe. We present a
systematic photometric analysis of very distant galaxies in the first JWST deep field towards …

We present the JWST cycle 1 53.8 h medium program FRESCO, short for 'First Reionization
Epoch Spectroscopically Complete Observations'. FRESCO covers 62 arcmin2 in each of …

ABSTRACT Spitzer/Infrared Array Camera (IRAC) imaging has revealed that the brightest
z∼ 7− 8 galaxies often exhibit young ages and strong nebular line emission, hinting at high …

JWST is revolutionizing our understanding of the high-z Universe by expanding the black
hole horizon, looking farther and to smaller masses, and revealing the stellar light of their …

We present the first constraints on the prevalence of z> 10 galaxies in the Hubble Ultra Deep
Field (HUDF) leveraging new NIRCam observations from JEMS (JWST Extragalactic …

The distribution of dark matter halo masses can be accurately predicted in the lambda cold
dark matter (ΛCDM) cosmology. The presence of a single massive halo or galaxy at a …

We introduce the thesan project, a suite of large volume () radiation-magnetohydrodynamic
simulations that simultaneously model the large-scale statistical properties of the …
