The spectrum of any star viewed through a sufficient quantity of diffuse interstellar material reveals a number of absorption features collectively called ‘diffuse interstellar bands’ (DIBs). The first DIBs were reported about 90 years ago, and currently well over 500 are known. None of them has been convincingly identified with any specific element or molecule, although recent studies suggest that the DIB carriers are polyatomic molecules containing carbon. Most of the DIBs currently known are… 
TRES survey of variable diffuse interstellar bands
Diffuse interstellar bands (DIBs) are absorption features commonly observed in optical/near-infrared spectra of stars and thought to be associated with polyatomic molecules that comprise a
Near-infrared diffuse interstellar bands towards Her 36
Discovered almost a century ago, the Diffuse Interstellar Bands (DIBs) still lack convincing and comprehensive identification. Hundreds of DIBs have now been observed in the near-ultraviolet (NUV),
Interaction between the broad-lined type IC supernova 2012ap and carriers of diffuse interstellar bands
Diffuse interstellar bands (DIBs) are absorption features observed in optical and near-infrared spectra that are thought to be associated with carbon-rich polyatomic molecules in interstellar gas.
MAPPING THE INTERSTELLAR MEDIUM WITH NEAR-INFRARED DIFFUSE INTERSTELLAR BANDS
We map the distribution and properties of the Milky Way's interstellar medium as traced by diffuse interstellar bands (DIBs) detected in near-infrared stellar spectra from the SDSS-III/APOGEE survey.
Near-IR Diffuse Interstellar Bands in SDSS-III APOGEE Spectra
Abstract Using high resolution H-band spectra from first-year observations of the SDSS-III APOGEE survey, we have searched for the presence of Diffuse Interstellar Bands (DIBs) towards several
NEAR INFRARED DIFFUSE INTERSTELLAR BANDS TOWARD THE CYGNUS OB2 ASSOCIATION
We obtained the near-infrared (NIR) high-resolution (R ≡ λ/Δλ ∼ 20,000) spectra of the seven brightest early-type stars in the Cygnus OB2 association for investigating the environmental dependence of
NEAR-INFRARED DIFFUSE INTERSTELLAR BANDS IN 0.91–1.32 μm
We present a comprehensive survey of diffuse interstellar bands (DIBs) in 0.91–1.32 μm with the newly developed near-infrared (NIR) spectrograph WINERED mounted on the Araki 1.3 m telescope in Japan.
A HIGH-RESOLUTION STUDY OF NEAR-INFRARED DIFFUSE INTERSTELLAR BANDS
We present high-resolution echelle spectroscopic observations of the two near-infrared (NIR) diffuse interstellar bands (DIBs) at 13175 Å and 11797.5 Å. The DIBs have been observed in a number of
The 15273 \AA\ diffuse interstellar band in the dark cloud Barnard 68
High obscuration of background stars behind dark clouds precludes the detection of optical diffuse interstellar bands (DIBs) and hence our knowledge of DIB carriers in these environments. Taking
Diffuse interstellar bands in fullerene planetary nebulae: the fullerenes - diffuse interstellar bands connection
We present high-resolution (R∼15,000) 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 hi

Detection of diffuse interstellar bands in the infrared
THE diffuse interstellar bands (DIBs) are spectral absorption features caused by interstellar matter but not identified with any known atomic or molecular lines. Since 1975, when 39 such bands were
Infrared and visual interstellar absorption features towards heavily reddened field stars
We present measurements of the 3.4-μm hydrocarbon dust absorption feature, and four visual diffuse interstellar bands, for 12 highly reddened [9.0 < A(V) < 15.8], early-type stars identified from the
Near-infrared absorption spectroscopy of interstellar hydrocarbon grains
We present new 3600 - 2700/cm (2.8 - 3.7 micrometer) spectra of objects whose extinction is dominated by dust in the diffuse interstellar medium. The observations presented here augment an ongoing

An infrared quintuplet near the Galactic center
A compact cluster of five luminous infrared sources has been found in the vicinity of the Galactic center radio arc. All of the sources have large polarizations in the near-infrared and deep silicate
H3+ in Diffuse Interstellar Clouds: A Tracer for the Cosmic-Ray Ionization Rate
Using high-resolution infrared spectroscopy we have surveyed twenty sight lines for H3+ absorption. H3+ is detected in eight diffuse cloud sight lines with column densities varying from 0.6 × 1014 to

Disclosing Identities in Diffuse Interstellar Bands
TLDR
Maier et al. (2) now have a suspect in custody as the molecule responsible for DIBs—the linear carbene molecule, l-C3H2—but more evidence will be needed to get a conviction.
