Active galactic nuclei (AGN) are energetic astrophysical sources powered by accretion onto
supermassive black holes in galaxies, and present unique observational signatures that …

Rocky planets are common around other stars, but their atmospheric properties remain
largely unconstrained. Thanks to a wealth of recent planet discoveries and upcoming …

Abstract The James Webb Space Telescope (JWST) Early Release Observations (EROs) is
a set of public outreach products created to mark the end of commissioning and the …

We have collected transit times for the TRAPPIST-1 system with the Spitzer Space
Telescope over four years. We add to these ground-based, HST, and K2 transit-time …

We present a comprehensive optical and near-infrared census of the fields of 90 short
gamma-ray bursts (GRBs) discovered in 2005–2021, constituting all short GRBs for which …

One aim of modern astronomy is to detect temperate, Earth-like exoplanets that are well
suited for atmospheric characterization. Recently, three Earth-sized planets were detected …

We analyze pre-explosion near-and mid-infrared (IR) imaging of the site of SN 2023ixf in the
nearby spiral galaxy M101 and characterize the candidate progenitor star. The star displays …

This is the first of a series of papers presenting the Modules for Experiments in Stellar
Astrophysics (MESA) Isochrones and Stellar Tracks (MIST) project, a new comprehensive …

We present new stellar mass functions at z∼ 6, z∼ 7, z∼ 8, z∼ 9 and, for the first time, z∼
10, constructed from∼ 800 Lyman-break galaxies previously identified over the eXtreme …

A complete accounting of nearby objects—from the highest-mass white dwarf progenitors
down to low-mass brown dwarfs—is now possible, thanks to an almost complete set of …
