JWST photometry detects CO, H2O, and CO2 ices in Galactic Center clouds, with >25% of carbon frozen in CO ice implying Z_GC ≳2.5 Z_⊙ under equal freezeout assumption.
Fermi LAT data analysis detects a time-evolving ~162-day periodic GeV signal from 4FGL J1913.2+0512 linked to SS 433, prominent in 2008-2018 but diminished afterward, indicating multi-year evolution in gamma-ray production efficiency or geometry.
New CO(2-1) observations of 112 clumps in outer Galactic clouds (14-23 kpc) yield velocity dispersion-size and mass-size power laws plus a declining virial parameter trend indicating most clumps are gravitationally unbound.
High-mass quiescent galaxies in clusters assemble more luminous stellar halos than field galaxies while low-mass cluster galaxies assemble less luminous ones over 0.1 < z < 1.
ALMA survey finds 4 starless cores in Orion B North consistent with turbulent collapse simulations; virial analysis indicates Chamaeleon I cores are less bound with external pressure dominating unlike Orion B North and Ophiuchus.
The paper reviews techniques for measuring protostellar accretion, analyzes methodological differences and caveats in comparing observations with simulations, and outlines next steps for a fuller picture.
