PHANGS-ML: The Universal Relation between PAH Band and Optical Line Ratios across Nearby Star-forming Galaxies

open access: yesThe Astrophysical Journal
The structure and chemistry of the dusty interstellar medium (ISM) are shaped by complex processes that depend on the local radiation field, gas composition, and dust grain properties. Of particular importance are polycyclic aromatic hydrocarbons (PAHs),

Diffuse Interstellar Bands and Their Families

open access: yes, 2006
Diffuse interstellar bands (DIBs) still await an explanation. One expects that some progress in this field will be possible when all the known DIBs are divided into families in such a way that only one carrier is responsible for all bands belonging to the given family.

Interstellar Lines and Diffuse Bands in the Spectrum of the Supergiant κ Cas

open access: yes, 2019
© 2019, Pleiades Publishing, Ltd. We have studied the interstellar lines and diffuse bands in the spectrum of the supergiant κ Cas using the CCD spectra obtained with the Echelle spectrograph of the 2 meter telescope at the peak Terskol observatory.

Probing the Local Bubble with diffuse interstellar bands

open access: yes, 2015
Context. The Sun traverses a low-density, hot entity called the Local Bubble. Despite its relevance to life on Earth, the conditions in the Local Bubble and its exact configuration are not very well known. Besides that, there is some unknown interstellar

Diffuse interstellar bands (DIB): co-planar doubly excited He and metal atoms embedded in Rydberg Matter

open access: yes, 2011
The interpretation of the more than 300 diffuse interstellar bands (DIBs) is one of the most long-standing problems in interstellar spectra since the two first bands were reported in 1921. We now predict the frequencies of 260 diffuse interstellar bands (

Polycyclic Aromatic Hydrocarbons and the Diffuse Interstellar Bands

open access: yes, 1986
The profiles, widths and positions of the Diffuse Interstellar Bands (DIB’s) are discussed. It is shown that the carriers of the DIB’s are molecular rather than impurities in grains. Polycyclic Aromatic Hydrocarbons (PAH’s) are attractive candidates for the DIB’s, in view of their likely abundance, their extreme stability, and the fact that these ...

Fine structure of profiles of weak diffuse interstellar bands

open access: yes, 2002
We present a very high resolution ($R=120\,000$–220 000) analysis of profiles of selected diffuse interstellar bands (DIBs): 4964, 4980, 4985, 5850 Å.

Spectroscopic families among diffuse interstellar bands

open access: yes, 2012
The inability to identify carriers of the diffuse interstellar bands (DIBs) is one of the longest standing problems in astronomy and astrochemistry. It is debated whether these carriers arise from dust or the gas component of the interstellar medium ...

Diffuse Interstellar Bands Toward HD 62542 [PDF]

open access: yes, 2005
Diffuse interstellar bands (DIBs) have been detected for the first time along the peculiar translucent line of sight toward HD 62542, which passes through a diffuse cloud core.
