Jin-Long Xu et al 2023 ApJL 944 L40
A neutral hydrogen survey with the Five-hundred-meter Aperture Spherical Telescope turned up an isolated spinning cloud of gas with no optical counterpart and an abundance of dark matter.

Water vapor, carbon monoxide, and hydroxide molecules are all apparent in spectra of the ultra-hot Jupiter WASP-18b, and Doppler shifts in the planet’s spectrum hint at atmospheric dynamics.
Alex McDaniel et al 2023 ApJ 943 168
Researchers detect gamma rays from galaxies with molecular outflows — a way that gas is removed from galaxies, potentially suppressing star formation — and find that outflows might lead to more gamma-ray emission.
Gilles Chabrier and Romain Lenoble 2023 ApJL 944 L33
The central bulge of our galaxy may have the same stellar and brown dwarf initial mass function as the galactic disk, suggesting that brown dwarfs form in the same way that stars do.

A recent cubesat mission aims to detect the extended atmospheres of nearby exoplanets undergoing atmospheric escape — a process thought to play a fundamental role in the evolution of exoplanetary atmospheres.
Fiamma Capitanio et al 2023 ApJ 943 129
The first observations by the Imaging X-ray Polarimetry Explorer of a weakly magnetized neutron star allowed researchers to place an upper limit on the object’s polarization and constrain its inclination.
