In a new model of the early universe, star formation is ignited in low-mass halos by a passing shock front in cosmic filaments that is self-sustained by energy injection from supernova explosions.

New high resolution imaging of a light-scattering dust ring and halo around the young star HD 35841 reveal the highly inclined (i = 85°) ring of debris down to a projected separation of ~12 AU for the first time.

CRLE, a serendipitously discovered dusty, starbursting galaxy at z = 5.667, is the highest-redshift, most luminous starburst in the COSMOS field, forming stars at a rate of at least 1500 M_⊙/yr in a region only ~3 kpc across.

The Hubble Deep UV Legacy Survey provides the deepest high-resolution ultraviolet data over such a large area — 100 square arcmin — taken to date.

B. Lanzoni et al 2018 ApJ 861 16

Based on measurements of radial velocities of 800 individual stars, the globular cluster M5 is shown to have one of the cleanest and most coherent rotation patterns ever observed for globular clusters.

An isolated cold galactic disk can become violently unstable, leading to fragmentation and formation of stellar clumps that increase the stellar disk velocity dispersion, forming an isolated lenticular galaxy.
