Diffuse Interstellar Bands in M33 [PDF]

Proceedings of the International Astronomical Union, 2013
AbstractWe present the first sample of diffuse interstellar bands (DIBs) in the nearby galaxy M33. Studying DIBs in other galaxies allows the behaviour of the carriers to be examined under interstellar conditions which can be quite different from those of the Milky Way, and to determine which DIB properties can be used as reliable probes of ...

Diffuse interstellar bands in fullerene planetary nebulae: the fullerenes – diffuse interstellar bands connection [PDF]

Astronomy & Astrophysics, 2013
We present high-resolution (R~15000) VLT/UVES optical spectra of two planetary nebulae (PNe; Tc 1 and M 1-20) where C60 (and C70) fullerenes have already been found. These spectra are of high-quality (S/N > 300) for PN Tc 1, which permits us to search for the expected electronic transitions of neutral C60 and diffuse interstellar bands (DIBs ...

Survey of Very Broad Diffuse Interstellar Bands [PDF]

The Astronomical Journal, 2020
Abstract This paper considers a very special set of a few interstellar features—broad diffuse interstellar bands (DIBs) at 4430, 4882, 5450, 5779, and 6175 ÅÅ. The set is small, and measurements of equivalent widths of these DIBs are challenging because of severe stellar, interstellar, and sometimes, also telluric contaminations inside ...

Diffuse Interstellar Bands in Emission [PDF]

Proceedings of SALT Science Conference 2015 — PoS(SSC2015), 2015
AbstractRecent Fabry-Pérot observations towards the galaxy NGC 1325 with the Southern African Large Telescope (SALT) led to the serendipitous discovery of an emission feature centered at 661.3 nm arising from material in the interstellar medium (ISM) of our Galaxy; this emission feature lies at the wavelength of one of the sharper and stronger diffuse ...

Diffuse Interstellar Band Profiles [PDF]

Proceedings of the International Astronomical Union, 2013
AbstractA short review of the profiles of diffuse interstellar bands and their possible interpretation is given, largely from the perspective of absorption by gas-phase molecules. Potentially a crucial source of information on the nature of the diffuse band carriers, profile studies provide a promising avenue of research towards finding the solution to

Laboratory infrared spectra and fragmentation chemistry of sulfur allotropes [PDF]

Nature Communications
Sulfur is one of six life-essential elements, but its path from interstellar clouds to planets and their atmospheres is not well known. Astronomical observations in dense clouds have so far been able to trace only 1 percent of cosmic sulfur, in the form ...

Mapping local interstellar medium with diffuse interstellar bands [PDF]

Monthly Notices of the Royal Astronomical Society, 2020
ABSTRACT With the use of the data from archives, we studied the correlations between the equivalent widths of four diffuse interstellar bands (4430, 5780, 5797, 6284 $\mathring{\rm A}$) and properties of the target stars (colour excess values, distances, and Galactic coordinates).

Diffuse Interstellar Bands [PDF]

Symposium - International Astronomical Union, 2000
The unidentified diffuse interstellar bands are observed in near-UV, visible and near-IR spectra recorded towards stars which are partially obscured by interstellar dust. Their origin is the longest standing problem in astronomical spectroscopy and dates back to the 1930s when systematic study of the bands first started.
