Variability of Sagittarius A* at 3 GHz on minute-scale with MeerKAT
K. Kaur, I. Rammala-Zitha, A. Basu +21
The supermassive black hole Sagittarius A* (Sgr A*) exhibits temporal and spectral variability across the electromagnetic spectrum. However, variability at radio frequencies below…
MeerKAT observations of the spiral galaxy NGC 2997 in the S band. Detection of high dynamo modes
A. Damas-Segovia, R. Beck, S. A. Mao +18
We seek to exploit the expanded observational range of the MeerKAT radio telescope with the new S-band receivers (2.0-2.8 GHz). To showcase its enhanced capabilities, we conducted…
A first glimpse at the MeerKAT DEEP2 field at S-band
S. Ranchod, J. D. Wagenveld, H. -R. Klöckner +15
We present the first widefield extragalactic continuum catalogue with the MeerKAT S-band (2.5 GHz), of the radio-selected DEEP2 field. The combined image over the S1 (1.96 - 2.84 G…
TRAPUM pulsar and transient search in the Sextans A and B galaxies and discovery of background FRB 20210924D
E. Carli, L. Levin, B. W. Stappers +10
The Small and Large Magellanic Clouds are the only galaxies outside our own in which radio pulsars have been discovered to date. The sensitivity of the MeerKAT radio interferometer…
The Galactic latitude dependency of Faraday complexity in the S-PASS/ATCA RM catalogue
S. Ranchod, S. A. Mao, R. Deane +4
The S-band Polarisation All Sky Survey (SPASS/ATCA) rotation measure (RM) catalogue is the largest broadband RM catalogue to date, increasing the RM density in the sparse southern…
The MPIfR-MeerKAT Galactic Plane survey I -- System setup and early results
P. V. Padmanabh, E. D. Barr, S. S. Sridhar +30
Galactic plane radio surveys play a key role in improving our understanding of a wide range of astrophysical phenomena. Performing such a survey using the latest interferometric te…
CHANG-ES XXIII: Influence of a galactic wind in NGC 5775
G. H. Heald, V. Heesen, S. S. Sridhar +22
We present new radio continuum images of the edge-on starburst galaxy NGC 5775, from LOFAR (140 MHz) and the Karl G. Jansky Very Large Array CHANG-ES survey (1500 MHz). We trace th…
Investigation of the cosmic ray population and magnetic field strength in the halo of NGC 891
D. D. Mulcahy, A. Horneffer, R. Beck +24
Low-frequency radio continuum observations of edge-on galaxies are ideal to study cosmic-ray electrons (CREs) in halos via radio synchrotron emission and to measure magnetic field…
What drives galactic magnetism?
Krzysztof T. Chyzy, Sarrrvesh S. Sridhar, Wojciech Jurusik
We aim to use statistical analysis of a large number of various galaxies to probe, model, and understand relations between different galaxy properties and magnetic fields. We have…
A plethora of diffuse steep spectrum radio sources in Abell 2034 revealed by LOFAR
T. W. Shimwell, J. Luckin, M. Brüggen +28
With Low-Frequency Array (LOFAR) observations, we have discovered a diverse assembly of steep spectrum emission that is apparently associated with the intra cluster medium (ICM) of…
Diversity in extinction laws of Type Ia supernovae measured between and
R. Amanullah, J. Johansson, A. Goobar +36
We present ultraviolet (UV) observations of six nearby Type~Ia supernovae (SNe~Ia) obtained with the Hubble Space Telescope, three of which were also observed in the near-IR (NIR)…
