Red quasars are intrinsically X-ray weak with low alpha_OX values, tracing a distinct evolutionary stage of suppressed black hole accretion relative to stellar mass growth.
Six years of UV/X-ray monitoring of ESO 511-G030 reveals a >10x UV rise from the accretion disk, tight disk-corona coupling above ~1% Eddington, and breakdown below, indicating an accretion-state transition.
FUor masses inferred from Keplerian line broadening in H-band spectra match the solar neighborhood IMF, indicating a universal eruptive phase during star formation.
Observational study of MBM12 shows CO-to-H2 conversion factor near galactic average with density-dependent variations, high virial parameters decreasing at small scales, broken power-law mass-size relations indicating external pressure, and magnetic field orientation transition at N(H2) = 4.5e21 cm-
New optical polarization data of over 90,000 stars shows H I filaments in the Riegel-Crutcher cloud tightly aligned with a coherent plane-of-sky magnetic field, indicating magnetic fields shape the cold neutral medium.
Five new HI 21-cm absorption detections in LERGs and HERGs at z<0.5 reveal disturbed gas kinematics with velocity offsets over 350 km/s and a 3% detection rate consistent with lower-redshift samples.
New infrared spectra show reduced water ice and unusually strong aliphatic hydrocarbon absorption towards W44, attributed to shock and cosmic-ray processing in the associated molecular cloud.
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.
