Violet absorption edges of C IV lines in Wolf-Rayet spectra: possible superposition with diffuse interstellar bands at 5780Å and 5797Å

, 1978
It is shown that the violet edges normally seen in Wolf-Rayet stars around 5800Å are principally due to displaced C IV absorption. The diffuse interstellar bands are seldom of comparable strength and can be seen separately if the absorption ...

Loop I/NPS Morphology Predictions in the Ultralong-wavelength Band

The Astrophysical Journal
Loop I/North Polar Spur (NPS) is the giant arc structure above the Galactic plane observed at radio wavelengths (≲10 GHz). There has been long-standing debate about its origin. While many people believe that it consists of nearby supernova remnants (SNRs)

Interstellar medium model [PDF]

, 1972
A model of the ionized part of the interstellar medium was developed, based on the low frequency observations by the Radio Astronomy Explorer Satellite with a background of nonthermal radiation.

Neutral gas and diffuse interstellar bands in the LMC [PDF]

, 1994
Tracing the dynamics of the neutral gas and observing diffuse interstellar bands in the LMC (Large Magellanic Cloud) was the focus of this study. The S/N values, a Quartz lamp exposure, a T horium Argon Comparision lamp exposure, and spectral plots for ...

Cyclic C4+ as the Carrier of the Diffuse Interstellar Band at 503.9 nm?

The Astrophysical Journal
The diffuse interstellar bands (DIBs) have remained a mystery in astronomy since their discovery over a century ago. The only currently known carrier is ${{\rm{C}}}_{60}^{+}$ , responsible for five DIBs, while more than 550 are yet to be interpreted. The

Infrared and Ultraviolet Properties of Polycyclic Aromatic Hydrocarbons: Constraints on the Carriers of AIBs and the 2175 Å Extinction Feature

The Astrophysical Journal
Polycyclic aromatic hydrocarbons (PAHs) are widely considered as the carriers of the aromatic infrared bands and possible contributors to the 2175 Å interstellar extinction feature.
