Some recent highlights:

All diffuse ICM radio sources are naturally explained as manifestations of the same relativistic ions

Virial shocks finally detected in radio: LWA

A new quasi-steady state explains the spiral structures and universal entropy profile in galaxy clusters

The Fermi bubbles must arise from jetted emission from the Milky-Way black hole

Dark matter pull seen in action: no lensing needed

The spectrum of pulsar wind nebule cores is maximally hard
