Astronomical observations reveal a major deficiency in our understanding of physics—the
detectable mass is insufficient to explain the observed motions in a huge variety of systems …

We review progress over the past decade in observations of large-scale star formation, with
a focus on the interface between extragalactic and Galactic studies. Methods of measuring …

Abstract The James Webb Space Telescope (JWST) discovered several luminous high-
redshift galaxy candidates with stellar masses of M*≳ 10 9 M⊙ at photometric redshifts z …

The formation process of intermediate-mass black holes (IMBHs), defined as those between
100 and 105 solar masses (M⊙), is debated. One potential origin is the growth of less …

We present an atlas of ultraviolet and infrared images of∼ 15,750 local (d≲ 50 Mpc)
galaxies, as observed by NASA's Wide-field Infrared Survey Explorer (WISE) and Galaxy …

Context. Observations with the James Webb Space Telescope (JWST) have revealed an
abundance of bright z> 10 galaxy candidates, challenging the predictions of most theoretical …

We explore a newly proposed channel to create binary black holes of stellar origin. This
scenario applies to massive, tight binaries where mixing induced by rotation and tides …

ABSTRACT We present new [] 88-observations of five bright z∼ 7 Lyman-break galaxies
spectroscopically confirmed by ALMA through [] 158, unlike recent [] detections where …

When two black holes merge in a dense star cluster, they form a new black hole with a well-
defined mass and spin. If that “second-generation” black hole remains in the cluster, it will …

The presence of a nearby companion alters the evolution of massive stars in binary systems,
leading to phenomena such as stellar mergers, x-ray binaries, and gamma-ray bursts …
