Theory of Pulsar Wind Nebulae [PDF]
Our understanding of Pulsar Wind Nebulae (PWNe), has greatly improved in the last years thanks to unprecedented high resolution images taken from the HUBBLE, CHANDRA and XMM satellites. The discovery of complex but similar inner features, with the presence of unexpected axisymmetric rings and jets, has prompted a new investigation into the dynamics of ...

Why (Still) Studying Turbulence in Fluids and Plasmas?
Abstract Turbulence, a captivating and intricate phenomenon, continues to attract researchers across diverse scientific disciplines. Despite considerable efforts, turbulence remains a fascinating challenge and stands as one of the unsolved enigmas in classical physics.

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
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.

The Mouse Pulsar Wind Nebula [PDF]
Abstract The young energetic pulsar J1747–2958 (τ = 26 kyr, erg s−1) powers the Mouse pulsar wind nebula (PWN), famous for its spectacular tail spanning 45″ in X-rays and 12′ in radio (d ∼ 5 kpc).

The Theory of Pulsar Winds and Nebulae [PDF]
We review current theoretical ideas on pulsar winds and their surrounding nebulae. Relativistic MHD models of the wind of the aligned rotator, and of the striped wind, together with models of magnetic dissipation are discussed. It is shown that the observational signature of this dissipation is likely to be point-like, rather than extended, and that ...

Supernova remnants in nearby galaxies
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.
