Neutrinos from the pulsar wind nebulae [PDF]

Astronomy & Astrophysics, 2003
In the recent paper we calculated the $\gamma$-ray spectra from pulsar wind nebulae (PWNe), assuming that a significant amount of the pulsar rotational energy is converted into relativistic nuclei.

MHD models of Pulsar Wind Nebulae [PDF]

, 2010
Pulsar Wind Nebulae (PWNe) are bubbles or relativistic plasma that form when the pulsar wind is confined by the SNR or the ISM. Recent observations have shown a richness of emission features that has driven a renewed interest in the theoretical modeling ...

Long‐Term Density Trend in the Mesosphere and Lower Thermosphere From Occultations of the Crab Nebula With X‐Ray Astronomy Satellites

Journal of Geophysical Research: Space Physics, Volume 128, Issue 2, February 2023., 2023
Abstract We present long‐term density trends of the Earth's upper atmosphere at altitudes between 71 and 116 km, based on atmospheric occultations of the Crab Nebula observed with X‐ray astronomy satellites, ASCA, RXTE, Suzaku, NuSTAR, and Hitomi. The combination of the five satellites provides a time period of 28 years from 1994 to 2022.

A search for runaway stars in 12 Galactic supernova remnants

Astronomische Nachrichten, Volume 342, Issue 3, Page 553-577, March 2021., 2021
Runaway stars can result from core‐collapse supernovae in multiple stellar systems. If the supernova disrupts the system, the companion is ejected with its former orbital velocity. A clear identification of a runaway star can yield the time and place of the explosion, as well as orbital parameters of the pre‐supernova binary system.

PULSAR WIND NEBULAE MODELING [PDF]

International Journal of Modern Physics: Conference Series, 2014
Pulsar Wind Nebulae (PWNe) are ideal astrophysical laboratories where high energy relativistic phenomena can be investigated. They are close, well resolved in our observations, and the knowledge derived in their study has a strong impact in many other fields, from AGNs to GRBs.

Supernova remnants in nearby galaxies

Astronomische Nachrichten, Volume 341, Issue 2, Page 156-162, February 2020., 2020
Abstract Supernova remnants (SNRs) are the aftermath of stellar explosions, which inject large amounts of energy into the interstellar medium (ISM), carving out new structures and transferring kinetic energy to the ISM. They also act as recycling centers, which return elements processed in stars to the ISM, and cosmic particle accelerators.
