Milliarcsecond Localisation of the Hyperactive Repeating FRB 20220912A

Danté M. Hewitt, Shivani Bhandari, Benito Marcote +23

We present very-long-baseline interferometry (VLBI) observations of the hyperactive repeating FRB 20220912A using the European VLBI Network (EVN) with an EVN-Lite setup. We detecte…

Are radio minihalos confined by cold fronts in galaxy clusters? Minihalos and large-scale sloshing in A3444 and MS 1455.0+2232

Simona Giacintucci, Tiziana Venturi, Maxim Markevitch +3

We present radio and X-ray studies of A3444 and MS1455.0+2232, two galaxy clusters with radio minihalos in their cool cores. A3444 is imaged using the Giant Metrewave Radio Telesco…

Jet reorientation in central galaxies of clusters and groups: insights from VLBA and Chandra data

Francesco Ubertosi, Gerrit Schellenberger, Ewan O'Sullivan +8

Recent observations of galaxy clusters and groups with misalignments between their central AGN jets and X-ray cavities, or with multiple misaligned cavities, have raised concerns a…

A Deep uGMRT view of the ultra steep spectrum radio halo in Abell 521

Ramananda Santra, Ruta Kale, Simona Giacintucci +8

We present the first detailed analysis of the ultra-steep spectrum radio halo in the merging galaxy cluster Abell 521, based on upgraded Giant Metrewave Radio telescope (uGMRT) obs…

Probing diffuse radio emission in bridges between galaxy clusters with uGMRT

G. V. Pignataro, A. Bonafede, G. Bernardi +3

The main purpose of this work is to investigate the properties of the non-thermal emission in the interacting clusters pairs Abell 0399-Abell 0401 and Abell 21-PSZ2 G114.9, found i…

Radio-continuum spectra of ram pressure stripped galaxies in the Coma Cluster

I. D. Roberts, R. J. van Weeren, D. V. Lal +7

We used the nearby Coma Cluster as a laboratory in order to probe the impact of ram pressure on star formation as well as to constrain the characteristic timescales and vel…
