Morphology of supernova remnants and their halos [PDF]
Astronomy & Astrophysics, 2021 Context. Supernova remnants (SNRs) are known to accelerate particles to relativistic energies, on account of their nonthermal emission. The observational progress from radio to gamma-ray observations reveals more and more morphological features that need to be accounted for when modeling the emission from those objects. Aims.

Magnetohydrodynamic Simulations of the Supernova Remnant G1.9+0.3
The Astrophysical Journal, 2023 The youngest Galactic supernova remnant G1.9+0.3 shows a discrete feature between its radio and X-ray morphologies. The observed radio morphology features a single maximum in the north, while the X-ray observation shows two opposite “ears” on the east ...

Supernova remnants: the X-ray perspective [PDF]
Astronomy and Astrophysics Reviews, Vol. 20, 1, (January 2012), 2011 Supernova remnants are beautiful astronomical objects that are also of high scientific interest, because they provide insights into supernova explosion mechanisms, and because they are the likely sources of Galactic cosmic rays. X-ray observations are an important means to study these objects.And in particular the advances made in X-ray imaging ...

Highlights of Astronomy, 1974 AbstractThe present structure and recent changes in Cas A are discussed. On the deepest available exposures the optical remnant of this supernova is seen to consist of an almost complete shell. The southern part of this shell is outlined by knots that have developed during the last decade.

On the nature of Tycho Brahe’s supernova
Frontiers in Astronomy and Space Sciences, 2023 At the 450 years anniversary of its observation, the supernova named after Tycho Brahe, SN 1572, can be explained in the terms used nowadays to characterize Type Ia supernovae (SNe Ia).

Multifrequency radio observations of SNR J0536-6735 (N 59B) with associated pulsar [PDF]
Serbian Astronomical Journal, 2012 We present a study of new Australian Telescope Compact Array (ATCA) observations of supernova remnant, SNR J0536-6735. This remnant appears to follow a shell morphology with a diameter of D=36x29 pc (with 1 pc uncertainty in each direction ...

XMMU J050722.1-684758: Discovery of a new Be X-ray binary pulsar likely associated with the supernova remnant MCSNR J0507-6847 [PDF]
, 2021 We report the discovery of a new high mass X-ray binary pulsar, XMMU J050722.1-684758, possibly associated with the supernova remnant MCSNR J0507-6847 in the Large Magellanic Cloud, using XMM-Newton X-ray observations. Pulsations with a periodicity of 570 s are discovered from the Be X-ray binary XMMU J050722.1-684758 confirming its nature as a HMXB ...

Publications of the Astronomical Society of Japan, 2020 Abstract An almost perfect round hole of CO-line emission with a diameter of 3.7 pc was found in a molecular cloud (MC) centered on G35.75−0.25 (l = 35${{^{\circ}_{.}}}$75, b = −0${{^{\circ}_{.}}}$25) at radial velocity of 28 km s−1.

Neutrinos from Supernovas and Supernova Remnants [PDF]
AIP Conference Proceedings, 2005 Supernovae (SN) and supernova remnants (SNR) have key roles in galaxies, but their physical descriptions is still incomplete. Thus, it is of interest to study neutrino radiation to understand SN and SNR better. We will discuss: (1) The ~10 MeV thermal neutrinos that arise from core collapse SN, that were observed for SN1987A, and can be seen with ...
