Non-Equilibrium X-Ray Emission from Young Supernova Remnants [PDF]

open access: yes, 1983
A computer model (NIE model) has been developed to predict the the x-ray spectra from the hot (106-8 K), shock-heated plasmas that are found in the rem­nants of supernovae. The model accounts for the lack of collisional ionization equilibrium and for the

Time-dependent escape of cosmic rays from supernova remnants potentially at the origin of the very-high-energy cosmic-ray gradient of the Galactic center [PDF]

open access: yes, 2020
International audienceThe distribution of the very-high-energy diffuse emission in the inner 200 pc measured by H.E.S.S. indicates the existence of a pronounced cosmic-ray (CR) gradient peaking on the Galactic center (GC).

Nuclear astrophysicists at war

open access: yesNatural Sciences, Volume 4, Issue 1, January 2024.
The Manhattan program not only opened the path to the nuclear age for humans, but also triggered a lot of new questions and research directions in nuclear physics and astrophysics that still inform the ideas in these fields today. Abstract The question of energy production in stars stimulated an entire generation of young physicists in the 1930s who ...

Simulating molecular cloud regulated star formation in Galaxies [PDF]

open access: yes, 2007
This thesis is primarily concerned with understanding the process of galaxy formation via the simulation of the interstellar medium, star formation and supernova feedback.

The influence of supernova remnants on the interstellar medium in the large magellanic cloud seen at 20-600 mu m wavelengths [PDF]

open access: yes, 2015
We present the analysis of supernova remnants (SNRs) in the Large Magellanic Cloud (LMC) and their influence on the environment at far-infrared (FIR) and submillimeter wavelengths.

Supernova remnants of red supergiants: From barrels to loops [PDF]

open access: yes
Core-collapse (CC) supernova remnants (SNRs) are the nebular leftovers of defunct massive stars that died during a supernova explosion, mostly while undergoing the red supergiant phase of their evolution.

Observations of cold dust in young supernova remnants [PDF]

open access: yes, 2003
The importance of supernovae as a source of interstellar dust has long been debated. Theoretical models predict that the final event in the life of a massive star (10--30 Modot) should produce 0.3--5Modot of dust.

Statistical Analysis of Simulated Supernova Remnants in Optical Band [PDF]

open access: yes, 2023
При вспышке сверхновой (СН) в межзвездную среду (МЗС) высвобождается около 1051 эрг. На поздних стадиях эволюции СН, около 70 % этой энергии теряется за счет радиационного охлаждения. Эти потери можно наблюдать в запрещенных оптических линиях.

Multi-Wavelength Observations of Supernova Remnants [PDF]

open access: yes, 2012
Supernova remnants (SNRs) provide a laboratory for studying various astrophysical processes, including particle acceleration, thermal and non thermal emission processes across the spectrum, distribution of heavy elements, the physics of strong shock ...

Thermal and Non-Thermal Contributions to the X-ray Spectrum of Large Magellanic Cloud Supernova Remnants [PDF]

open access: yes, 2003
The study of supernovae and the expanding remnants that form after the explosion is important to understanding star formation and the distribution of elements in the interstellar medium (ISM).
