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 ...

Particle propagation in clumpy supernova remnants [PDF]

EPJ Web of Conferences, 2019
The presence of dense clumps in the environment where a supernova remnant expands might have a strong impact in shaping the observed hadronic gamma-ray spectrum.

Understanding the origin of supernova remnants with plasma diagnostics

, 2022
Supernova remnants provide kinetic energy, heavy elements, and accelerated particles into the space. In other words, supernova remnants make the diversity of our Universe.

Rapid Expansion of the Young Type Ia Supernova Remnant 0519–69.0: More Evidence for a Circumstellar Shell

The Astrophysical Journal, 2023
The nature of Type Ia supernovae remains controversial. The youngest remnants of Ia supernovae hold clues to the explosion and to the immediate surroundings. We present a third epoch of Chandra observations of the ∼600 yr old Type Ia remnant 0519–69.0 in

Pulsar activity and the morphology of supernova remnants [PDF]

, 1980
We use the recently introduced concept of a ' window ' of magnetic field strengths in which pulsars can be active to explain the variation in morphology of supernova remnants.

Magneto-hydrodynamical simulation with cosmic ray acceleration at supernova remnants. [PDF]

, 2020
Supernova remnants shocks are considered the best sites for the production of Galactic cosmic rays. The interactions of cosmic rays produced at supernova shocks with photon fields and the interstellar medium generate a multi-wavelength spectrum from ...

Mixing of materials in magnetised core-collapse supernova remnants

, 2023
Core-collapse supernova remnants are structures of the interstellar medium (ISM) left behind the explosive death of most massive stars (⁠≲40M⊙⁠). Since they result in the expansion of the supernova shock wave into the gaseous environment shaped by the ...

Supernova remnants dynamics

, 2017
Supernova remnants are the site of a number of physical processes (shock-heating, non-equilibrium ionization, hydrodynamic instabilities, particle acceleration, magnetic field amplification).

The Effects of Elemental Abundances on Fitting Supernova Remnant Models to Data

Universe, 2022
Models for supernova remnant (SNR) evolution can be used to determine the energy of the explosion, the age of the SNR, and the density of the surrounding medium by matching observations. Observed SNR properties derived from the X-ray spectrum include the
