Interacción entre el RSN G359.1-0.5 y el medio interestelar
(Asociación Argentina de Astronomía, 2020)
G359.1-0.5 es un remanente de supernova detectado en dirección al centro de la Galaxia que presenta una morfología del tipo cáscara en el continuo de radio y emisión de rayos X extendida de naturaleza térmica en su interior, ...
The electron-capture origin of supernova 2018zd
(Nature Research, 2021-09-21)
In the transitional mass range (~8?10 solar masses) between white dwarf formation and iron core-collapse supernovae, stars are expected to produce an electron-capture supernova. Theoretically, these progenitors are thought ...
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. ...
Non-thermal emission produced by the interaction of a jet with a supernova remnant
(World Scientific, 2018)
Core-collapse supernovae (SNe) are found in galaxies with ongoing star-formation. If a starburst galaxy hosts an active galactic nucleus (AGN) with a relativistic jet, the SN could take place inside the jet. The collision ...
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 ...
