Abstract The Laser Interferometer Space Antenna (LISA) will be a transformative experiment
for gravitational wave astronomy, and, as such, it will offer unique opportunities to address …

Spurred by rich, multiwavelength observations and enabled by new simulations, ranging
from cosmological to subparsec scales, the past decade has seen major theoretical …

The NANOGrav 15 yr data set shows evidence for the presence of a low-frequency
gravitational-wave background (GWB). While many physical processes can source such low …

We present rest-frame optical data of the compact z= 5.55 galaxy GS_3073 obtained using
the integral field spectroscopy mode of the Near-InfraRed Spectrograph on board the James …

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 …

Here we provide the most comprehensive determinations of the rest-frame UV luminosity
function (LF) available to date with the Hubble Space Telescope (HST) at z∼ 2–9 …

Dark matter represents currently an outstanding problem in both cosmology and particle
physics. In this review we discuss the possible explanations for dark matter and the …

ABSTRACT I introduce some improvements to the ppxf method, which measures the stellar
and gas kinematics, star formation history (SFH) and chemical composition of galaxies. I …

Over recent decades, cosmological simulations of galaxy formation have been instrumental
in advancing our understanding of structure and galaxy formation in the Universe. These …

We introduce the simba simulations, the next generation of the mufasa cosmological galaxy
formation simulations run with gizmo's meshless finite mass hydrodynamics. simba includes …
