Very Long Baseline Interferometry Search for The Radio Counterpart Of Hess J1943+213
(Iop Publishing Ltd, 2013-01-01)
HESS J1943+213, a TeV point source close to the Galactic plane recently discovered by the H.E.S.S. Collaboration, was proposed to be an extreme BL Lacertae object, though a pulsar wind nebula (PWN) nature could not be ...
Radio counterparts of gamma-ray sources in the Cygnus region
(IOP Publishing, 2021-02)
The view of the gamma-ray universe is being continuously expanded by space high-energy (HE) and ground-based very-high-energy (VHE) observatories. Yet, the angular resolution limitation still precludes a straightforward ...
X-ray emitting structures in the Vela SNR: Ejecta anisotropies and progenitor stellar wind residuals
(EDP Sciences, 2021-05)
Context. The Vela supernova remnant (SNR) shows several ejecta fragments (or shrapnel) protruding beyond the forward shock, which are most likely relics of anisotropies that developed during the supernova (SN) explosion. ...
Possible Evidence for Cosmic-Ray Acceleration in the Type Ia SNR RCW 86: Spatial Correlation between TeV Gamma-Rays and Interstellar Atomic Protons
(IOP Publishing, 2019-04)
We present a detailed morphological study of TeV gamma-rays, synchrotron radiation, and interstellar gas in the young Type Ia supernova remnant (SNR) RCW 86. We find that the interstellar atomic gas shows good spatial ...
Discovery of a pulsar-powered bow shock nebula in the Small Magellanic Cloud supernova remnant DEMS5
(Wiley Blackwell Publishing, Inc, 2019-06)
We report the discovery of a new Small Magellanic Cloud pulsar wind nebula (PWN) at the edge of the supernova remnant (SNR) DEMS5. The pulsar powered object has a cometary morphology similar to the Galactic PWN analogues ...
The interstellar medium and the massive stellar content towards the SNR G18.1-0.1 and neighbouring H II regions
(Wiley Blackwell Publishing, Inc, 2013-06)
We perform a multiwavelength study of the SNR G18.1-0.1 and nearby several H II regions (infrared dust bubbles N21 and N22, and the H II regions G018.149-00.283 and G18.197-00.181). Our goal is to provide observational ...
Radio study of the extended TeV source VER J1907+062
(Wiley Blackwell Publishing, Inc, 2020-02)
This paper aims to provide new insights on the origin of the TeV source VER J1907+062 through new high-quality radio observations. We used the Karl G. Jansky Very Large Array (VLA) to observe the whole extension of VER ...
New VLA observations of the SNR Puppis A : the radio properties and the correlation with the X-ray emission
(EDP Sciences, 2006-12)
Context. High-resolution, high-sensitivity multifrequency radio images of supernova remnants (SNRs) are essential in advancing the understanding of both the global SNR dynamics and particle acceleration mechanisms. Aims. ...
A 3D MHD simulation of SN 1006: a polarized emission study for the turbulent case
(Oxford University Press, 2017-01)
Three dimensional magnetohydrodynamical simulations were carried out in order to perform a new polarization study of the radio emission of the supernova remnant SN 1006. These simulations consider that the remnant expands ...
Discovery of gamma-ray emission from the extragalactic pulsar wind nebula N 157B with H.E.S.S.
(EDP Sciences, 2012-08)
We present the significant detection of the first extragalactic pulsar wind nebula (PWN) detected in gamma rays, N 157B, located in the large" "Magellanic Cloud (LMC). Pulsars with high spin-down luminosity are found to ...
