C60 Cation as the Carrier of the 9577 and 9632 Angstrom Diffuse Interstellar Bands: Further Support from the VLT/X-Shooter Spectra
T. P. Nie, F. Y. Xiang, Aigen Li
Ever since their first detection over 100 years ago, the mysterious diffuse interstellar bands (DIBs), a set of several hundred broad absorption features seen against distant stars…
Probing the Missing Link between the Diffuse Interstellar Bands and the Total-to-Selective Extinction Ratio I. Extinction versus Reddening
Kaijun Li, Aigen Li, F. Y. Xiang
The carriers of the still (mostly) unidentified diffuse interstellar bands (DIBs) have been a long-standing mystery ever since their first discovery exactly 100 years ago. In recen…
Unusual Infrared Emission toward Sgr B2: Possible Planar C
X. H. Chen, F. Y. Xiang, X. J. Yang +1
Interstellar graphene could be present in the interstellar medium (ISM), resulting from the photochemical processing of polycyclic aromatic hydrocarbon (PAH) molecules and/or colli…
Diffuse Interstellar Bands and the Ultraviolet Extinction Curves: The Missing Link Revisited
F. Y. Xiang, Aigen Li, J. X. Zhong
A large number of interstellar absorption features at ~ 4000Å -- 1.8 μm, known as the "diffuse interstellar bands" (DIBs), remains unidentified. Most recent works relate them to la…
A Tale of Two Mysteries in Interstellar Astrophysics: The 2175 Angstrom Extinction Bump and Diffuse Interstellar Bands
F. Y. Xiang, Aigen Li, J. X. Zhong
The diffuse interstellar bands (DIBs) are ubiquitous absorption spectral features arising from the tenuous material in the space between stars -- the interstellar medium (ISM). Sin…
