Mass-loading of bow shock pulsar wind nebulae [PDF]

, 2015
We investigate the dynamics of bow shock nebulae created by pulsars moving supersonically through a partially ionized interstellar medium. A fraction of interstellar neutral hydrogen atoms penetrating into the tail region of a pulsar wind will undergo ...

The dynamics of interstellar cloud complexes [PDF]

Monthly Notices of the Royal Astronomical Society, 1988
Description d'une simulation numerique de l'evolution d'un nuage moleculaire geant de 1,5×10 5 M ○. consistant initialement en 48 nuages de masses egales se deplacant avec des vitesses supersoniques aleatoires. Les resultats montrent que, si l'energie dans le mouvement chaotique est inferieure a la valeur du viriel, une grande fraction de la matiere ...

Continuous solutions of cosmic-rays and waves in astrophysical environments

Scientific Reports, 2023
The propagation of energetic charged particles and cosmic rays in magnetized thermal plasma is focused. We consider a four-fluid system that consists of thermal plasma, cosmic rays, and two opposite propagating Alfvén waves to investigate the dynamics ...

SOFIA Observations of 30 Doradus. II. Magnetic Fields and Large-scale Gas Kinematics

The Astrophysical Journal, 2023
The heart of the Large Magellanic Cloud, 30 Doradus, is a complex region with a clear core-halo structure. Feedback from the stellar cluster R136 has been shown to be the main source of energy creating multiple parsec-scale expanding-shells in the outer ...

Time-resolved relaxation and fragmentation of polycyclic aromatic hydrocarbons investigated in the ultrafast XUV-IR regime

Nature Communications, 2021
Polycyclic aromatic hydrocarbons play an important role in interstellar chemistry, where interaction with high energy photons can induce ionization and fragmentation reactions.

Valence Threshold Photoionization Spectra of C $_5$ H and C $_5$ H $_2$ Isomers. [PDF]

Chemphyschem
Mass‐selected threshold photoelectron spectra (TPES) of l‐C5H, HC5H, and c–C3H‐CCH were recorded using double‐imaging photoelectron‐photoion coincidence spectroscopy. These transient species were generated in situ by hydrogen abstraction from cyclopropylacetylene and 1,3‐pentadiyne.

The Turbulent Interstellar Medium [PDF]

, 2006
An overview is presented of the main properties of the interstellar medium. Evidence is summarized that the interstellar medium is highly turbulent, driven on different length scales by various energetic processes.

The Mystery of the Cosmic Diffuse Ultraviolet Background Radiation [PDF]

, 2014
The diffuse cosmic background radiation in the GALEX far ultraviolet (FUV, 1300 \AA\ - 1700 \AA) is deduced to originate only partially in the dust-scattered radiation of FUV-emitting stars: the source of a substantial fraction of the FUV background ...

Physical Structure of Small Wolf-Rayet Ring Nebulae [PDF]

, 1998
We have selected the seven most well-defined WR ring nebulae in the LMC (Br 2, Br 10, Br 13, Br 40a, Br 48, Br 52, and Br 100) to study their physical nature and evolutionary stages. New CCD imaging and echelle observations have been obtained for five of

Anomalous diffusion of cosmic rays: A geometric approach

AIP Advances, 2021
In this work, we analyze the process leading to the occurrence of anomalous transport phenomena associated with galactic cosmic rays propagating through the interstellar space.
