A Plasma Instability Theory of Gamma-Ray Burst Emission [PDF]

, 1999
A new theory for gamma-ray burst radiation is presented. In this theory, magnetic fields and relativistic electrons are created through plasma processes arising as a relativistic shell passes through the interstellar medium.

Supernovae Origin for the Low-latitude Intermediate-velocity Arch and the North Celestial Pole Loop

The Astrophysical Journal, 2023
Supernova explosions attributed to the unseen companion in several binary systems identified by the Third Gaia Data Release (Gaia DR3) may be responsible for a number of well-known and well-studied features in the radio sky, including the low-latitude ...

Supersonic turbulence and structure of interstellar molecular clouds [PDF]

, 2002
The interstellar medium (ISM) provides a unique laboratory for highly supersonic, driven hydrodynamics turbulence. We present a theory of such turbulence, confirm it by numerical simulations, and use the results to explain observational properties of ...

From synthetic SEDs to stellar origins: A deep learning model for physical parameter retrieval in hot subdwarf stars

Astronomy & Astrophysics
Aims. The formation mechanisms of spectrally diverse hot subdwarfs remain unclear. While existing mass distribution analyses suggest additional channels beyond helium white dwarf (He-WD) mergers contribute to He-rich subdwarf formation, these conclusions

A future interstellar probe on the dynamic heliosphere and its interaction with the very local interstellar medium: In-situ particle and fields measurements and remotely sensed ENAs

Frontiers in Astronomy and Space Sciences, 2023
The recently published Interstellar Probe (ISP) study report describes a pragmatic mission concept with a launch window that starts in 2036 and is expected to reach several hundreds of astronomical units past the heliopause within a time frame of ≥50 ...
