A deep search for high-redshift galaxies in some of the richest JWST imaging to date emphasizes the importance of medium-band filters in excluding low-redshift interlopers and maximizing completeness.

In simulations featuring an inner disk tilted by 30 degrees, the outer disk develops a thermally driven warp due to launching of bending waves, which drives a tilting response in the outer disk.

Two newly discovered brown dwarfs occupy an underpopulated region of the brown dwarf mass–period parameter space; one brown dwarf appears to be under luminous, which is rare among brown dwarfs.

New modeling shows that super-Eddington accretion can account for the lack of observed variability in little red dots; if their accretion is sub-Eddington, photometric variability should have been detected by now.

Of the 68 brown dwarfs identified in a recent study, 12 are newly discovered and two are more than 5 kiloparsecs away, making them the most distant known brown dwarfs in our galaxy.

Examination of SN 2023ixf’s light curve has led to the identification of 2–3 potential ejecta shells, which the authors attribute to stochastic jet launching by the newborn neutron star.
