X-ray detection of M~1.3 merger shock in A2142, reproduced by off-axis merger simulations, with radio arcs interpreted as shock-induced vortex rings and ultra-long tails explained by post-shock electron re-acceleration and plasma stretching.

Deep Chandra data confirms three cold fronts in RXJ2014.8-2430 with widths indicating suppressed diffusion and identifies a concave structure consistent with either a Kelvin-Helmholtz instability or a powerful AGN cavity of radius 200-330 kpc.
Power-law modeling of gas mass fraction and temperature variation reconciles observed X-ray scaling relations in galaxy clusters, reducing >3σ tensions from 49% to 11% and yielding a redshift-independent mass proxy Y_LGT0.

A merger shock traced by radio arcs and ultra-long radio tails in galaxy cluster A2142
X-ray detection of M~1.3 merger shock in A2142, reproduced by off-axis merger simulations, with radio arcs interpreted as shock-induced vortex rings and ultra-long tails explained by post-shock electron re-acceleration and plasma stretching.
