The TDE AT2020vwl showed a third radio flare at the time a jet-wind collision was predicted from its first two flares, the first predicted-and-confirmed third flare.

abstract
We review the progress that has been made in observing and analyzing molecular cloud structure in recent years. Structures are self-similar over a wide range of scales with similar power law indices independent of the star forming nature of a cloud. Comparison of structures at parsec-scale resolution in a star forming and non-star forming cloud show that the average densities in the former are higher but the structural characteristics in each cloud are much the same. In gravitationally bound regions of a cloud, however, and at higher densities and resolution, the self-similar scaling relationships break down and it is possible to observe the first steps toward star formation. High resolution observations of the dense individual star forming cores within the clumps hold the key to an empirical understanding of the origins of the stellar initial mass function.

Dense 'superclumps' inside the seven local superclouds show characteristic 150-380 pc spacings, linking large-scale gas fragmentation to the sites of star formation.
N2H+ observations of six infrared-dark hub-filament systems show quiescent filaments converging toward dynamically complex hubs, with similar centroid velocity spreads across clumps spanning a factor of about 20 in mass.
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.
Simulations of collapsing cores find that ε_ff varies with core definition via density threshold, open vs closed boundaries, and initial density, with higher values in low-mass cores due to lower infall rates.

The efficiency per free-fall time as a ratio of the Star Formation Rate to the gas-infall rate in collapsing cores: dependence on the core definition, accretion, and radial structure
Simulations of collapsing cores find that ε_ff varies with core definition via density threshold, open vs closed boundaries, and initial density, with higher values in low-mass cores due to lower infall rates.
