A MeerKAT-meets-LOFAR study of Abell 1413: a moderately disturbed non-cool-core cluster hosting a kpc 'mini'-halo
C. J. Riseley, N. Biava, G. Lusetti +12
Many relaxed cool-core clusters host diffuse radio emission on scales of hundreds of kiloparsecs: mini-haloes. However, the mechanism responsible for generating them, as well as th…
New filamentary remnant radio emission and duty cycle constraints in the radio galaxy NGC 6086
S. Candini, M. Brienza, A. Bonafede +6
Radio galaxies are a subclass of active galactic nuclei in which accretion onto the supermassive black hole releases energy via relativistic jets. The jets are not constantly activ…
NGC 1436: the making of a lenticular galaxy in the Fornax cluster
Alessandro Loni, Paolo Serra, Marc Sarzi +25
We study the evolutionary path of the Fornax cluster galaxy NGC1436, which is known to be currently transitioning from a spiral into a lenticular morphology. This galaxy hosts a…
The MeerKAT Fornax Survey II. The rapid removal of HI from dwarf galaxies in the Fornax cluster
D. Kleiner, P. Serra, F. M. Maccagni +12
We present MeerKAT Fornax Survey atomic hydrogen (HI) observations of the dwarf galaxies located in the central ~2.5 x 4 deg of the Fornax galaxy cluster. The HI images present…
The MeerKAT Fornax Survey -- I. Survey description and first evidence of ram pressure in the Fornax galaxy cluster
P. Serra, F. M. Maccagni, D. Kleiner +22
The MeerKAT Fornax Survey maps the distribution and kinematics of atomic neutral hydrogen gas (HI) in the nearby Fornax galaxy cluster using the MeerKAT telescope. The 12 deg^2 sur…
A depolarizing HI tidal tail in the western lobe of Fornax A
Francesca Loi, Paolo Serra, Matteo Murgia +8
Recent MeerKAT neutral hydrogen (HI) observations of Fornax A reveal tidal material intersecting in projection the western lobe of this radio galaxy. We found a spatial coincidence…
AGN feeding and feedback in Fornax A: kinematical analysis of the multi-phase ISM
F. M. Maccagni, P. Serra, M. Gaspari +10
We present a multi-wavelength study of the gaseous medium surrounding the nearby active galactic nucleus (AGN) Fornax A. Using MeerKAT, ALMA and MUSE observations we reveal a compl…
A new look at old friends. I. Imaging classical radio galaxies with uGMRT and MeerKAT
B. Fanaroff, D. V. Lal, T. Venturi +9
We have undertaken a systematic study of FRI and FRII radio galaxies with the upgraded Giant Metrewave Radio Telescope (uGMRT) and MeerKAT. The main goal is to explore whether the…
MeerKAT-64 discovers wide-spread tidal debris in the nearby NGC 7232 galaxy group
Brenda Namumba, Baerbel Silvia Koribalski, Gyula I. G. Józsa +24
We report the discovery of large amounts of previously undetected cold neutral atomic hydrogen (\HI) around the core triplet galaxies in the nearby NGC~7232 galaxy group with MeerK…
A blind ATCA HI survey of the Fornax galaxy cluster: properties of the HI detections
A. Loni, P. Serra, D. Kleiner +15
We present the first interferometric blind HI survey of the Fornax galaxy cluster, which covers an area of 15 deg out to the cluster . The survey has a resolution of 6…
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…
A radio ridge connecting two galaxy clusters in a filament of the cosmic web
F. Govoni, E. Orrù, A. Bonafede +26
Galaxy clusters are the most massive gravitationally bound structures in the Universe. They grow by accreting smaller structures in a merging process that produces shocks and turbu…
Simulations of the polarized radio sky and predictions on the confusion limit in polarization for future radio surveys
F. Loi, M. Murgia, F. Govoni +4
Numerical simulations offer the unique possibility to forecast the results of surveys and targeted observations that will be performed with next generation instruments like the Squ…
Duty cycle of the radio galaxy B2 0258+35
M. Brienza, R. Morganti, M. Murgia +14
Radio loud Active Galactic Nuclei are episodic in nature, cycling through periods of activity and quiescence. In this work we investigate the duty cycle of the radio galaxy B2~0258…
Sardinia Radio Telescope wide-band spectral-polarimetric observations of the galaxy cluster 3C 129
M. Murgia, F. Govoni, E. Carretti +27
We present new observations of the galaxy cluster 3C 129 obtained with the Sardinia Radio Telescope in the frequency range 6000-7200 MHz, with the aim to image the large-angular-sc…
