Unraveling Baroclinicity in Black Hole Weather Storms
Denis Wittor, Massimo Gaspari
In the intracluster, intragroup, and circumgalactic medium (ICM, IGrM, CGM), turbulence plays a vital role in the self-regulated feedback and feeding cycle of central supermassive…
Bent it like FRs: extended radio AGN in the COSMOS field and their large-scale environment
Eleni Vardoulaki, Franco Vazza, Eric F. Jiménez-Andrade +3
One of the fascinating topics in radio astronomy is how to associate the complexity of observed radio structures to their environment, in order to understand their interplay and th…
Physical insights from the spectrum of the radio halo in MACS J0717.5+3745
K. Rajpurohit, G. Brunetti, A. Bonafede +18
We present new LOFAR observations of the massive merging galaxy cluster MACS J0717.5+3745. The cluster hosts the most powerful radio halo known to date. These new observations, in…
Understanding the radio relic emission in the galaxy cluster MACS J0717.5+3745: spectral analysis
K. Rajpurohit, D. Wittor, R. J. van Weeren +21
Radio relics are diffuse, extended synchrotron sources that originate from shock fronts generated during cluster mergers. The massive merging galaxy cluster MACS J0717.5+3745 hosts…
Dissecting the turbulent weather driven by mechanical AGN feedback
D. Wittor, M. Gaspari
Turbulence in the intracluster, intragroup, and circumgalactic medium plays a crucial role in the self-regulated feeding and feedback loop of central supermassive black holes. We d…
Spectro-polarimetric observations of the CIZA J2242.8+5301 northern radio relic: no evidence of high-frequency steepening
Francesca Loi, Matteo Murgia, Valentina Vacca +16
Observations of radio relics at very high frequency (>10 GHz) can help to understand how particles age and are (re-)accelerated in galaxy cluster outskirts and how magnetic fields…
