Observations of ionized carbon towards the -ray-bright supernova remnant RX J1713.7-3946
A. R. Thakur, G. P. Rowell, R. Higgins +7
The origin of Galactic Cosmic Rays (CRs), particularly at sub-GeV energies, remains uncertain due to their difficulty in being traced. One possible tracer of low-energy CRs is ioni…
Search for long-term variability of HESS J1745-290
H. E. S. S. Collaboration, :, A. Acharyya +116
At the center of our Galaxy lies the bright γ-ray point-like source HESS J1745-290, which is compatible in position with Sgr A star, although an association between the two remains…
H.E.S.S. observations of composite Seyfert-starburst galaxies
H. E. S. S. Collaboration, A. Acharyya, F. Aharonian +119
Context: Composite galaxies that contain both Seyfert and starburst components may produce very high-energy (VHE; >100 GeV) gamma-ray emission at a wide range of spatial scales, fr…
The second H.E.S.S. gamma-ray burst catalogue: 15 years of observations with the H.E.S.S. telescopes
A. Acharyya, F. Aharonian, C. Arcaro +143
Recent observational efforts using imaging atmospheric Cherenkov telescopes (IACTs) have led to firm detections of very-high-energy (VHE) signals from bright gamma-ray bursts (GRBs…
Scrutinizing the 2020 multiwavelength outburst of PKS 0903-57 through observations with H.E.S.S
A. Acharyya, F. Aharonian, F. Ait Benkhali +138
The blazar PKS 0903-57 has recently been classified as a flat spectrum radio quasar at a redshift of . In March and April 2020, Fermi-LAT and AGILE reported tremendous ac…
Multi-frequency radio-continuum study of the LMC SNR N206 (Goat's Eye) and its "zig-zag" PWN
M. Ghavam, Z. J. Smeaton, M. D. Filipovic +17
We present new radio-continuum observations of the Large Magellanic Cloud (LMC) supernova remnant (SNR) N206, which we give the name "Goat's Eye". Goat's Eye contains an interior r…
Evolutionary Map of the Universe: Detection of the Wolf-Rayet Star WR40
A. C. Bradley, Z. J. Smeaton, M. D. Filipovic +6
We present a radio-continuum detection of the well-known Wolf-Rayet star WR40 at 943.5 MHz using observations from the EMU survey. We find that the shell surrounding WR40, known as…
KIC 9272276: An Extreme Low Mass Ratio Red Nova Progenitor
Surjit Wadhwa, Marko Grozdanovic, Bojan Arbutina +2
Photometric analysis of KIC 9272276 (K9272), a low-mass contact binary system, is presented. We find it to be an example of an extreme low mass ratio system that satisfies the curr…
Evolutionary Map of the Universe: Detection and Analysis of the Shell Surrounding the Runaway Wolf-Rayet Star WR16
A. C. Bradley, M. D. Filipović, Z. J. Smeaton +18
We present the first radio--continuum detection of the circumstellar shell around the well-known WN8 type Wolf-Rayet star WR16 at 943.5\,MHz using the \ac{ASKAP} \ac{EMU} survey. A…
ASKAP-EMU radio continuum detection of planetary nebula NGC 5189: the "Infinity" nebula
A. D. Asher, Z. J. Smeaton, M. D. Filipović +4
We report the radio continuum detection of well known Galactic Planetary Nebula (PN) NGC 5189, observed at 943 MHz during the Australian Square Kilometre Array Pathfinder (ASKAP) E…
Investigating Unusual H Features towards the Scutum Supershell
R. Alsulami, S. Einecke, G. P. Rowell +7
We investigate the unusual H features found towards the Scutum Supershell via recent arc-minute and arc-second resolution imaging. These multi-degree features resemble a long ce…
The TRAPUM Small Magellanic Cloud pulsar survey with MeerKAT: I. Discovery of seven new pulsars and two Pulsar Wind Nebula associations
E. Carli, L. Levin, B. W. Stappers +17
The sensitivity of the MeerKAT radio interferometer is an opportunity to probe deeper into the population of rare and faint extragalactic pulsars. The TRAPUM (TRAnsients and PUlsar…
Fast as Potoroo: Radio Continuum Detection of a Bow-Shock Pulsar Wind Nebula Powered by Pulsar J1638-4713
Sanja Lazarević, Miroslav D. Filipović, Shi Dai +19
We report the discovery of a bow-shock pulsar wind nebula (PWN), named Potoroo, and the detection of a young pulsar J1638-4713 that powers the nebula. We present a radio continuum…
