A team led by Andrea Botteon used Chandra and eROSITA X-rays to trace the radio 'Treble Clef' to a black hole outburst and a cluster collision. The authors call the two-stage origin likely; the merger evidence comes from the shape of the cluster's hot gas.

INAF-led researchers sorted 300 well-characterized multiplanet systems into two families that track host-star mass and metal content. In Nature Astronomy, the authors say the split holds up against detection bias.

Explaining a 300 TeV photon candidate from GRB 221009A takes Lorentz invariance violation, not axion-like particles alone
Galanti and Roncadelli calculate that standard physics expects about 10^-96 photons at 300 TeV, the energy of the Carpet detector's photon-like event. Their fix, combining axion-like particles with a violation of Lorentz invariance, is needed only if that single event was a genuine photon.

China's Einstein Probe traced a pulsar's X-ray tail out to 42 light-years
The Einstein Probe found the X-ray tail of PSR J1740+1000 running about 42 light-years southwest, in the same direction as ultrahigh-energy gamma rays LHAASO had no clear counterpart for.

A by-eye search of VST images multiplies the known dwarf galaxies around three hosts twelvefold
An INAF-led team searched the deepest optical images yet taken of the fields around NGC 5068, NGC 5084 and NGC 5087 by eye, logging 47 dwarf galaxy candidates that spectroscopy has still to confirm as satellites.
