Ultraviolet Interstellar Extinction toward High Galactic Latitudes
Ajay Mishra, Aigen Li
Nearby high Galactic latitude clouds provide a unique laboratory to study the physics and structure of the Galactic interstellar medium (ISM) and the properties of the interstellar…
Polycyclic Aromatic Hydrocarbon Molecules and the 2175 Angstrom Interstellar Extinction Bump
Qi Lin, X. J. Yang, Aigen Li
The exact nature of the 2175 Angstrom extinction bump, the strongest spectroscopic absorption feature superimposed on the interstellar extinction curve, remains unknown ever since…
Deuterated Polycyclic Aromatic Hydrocarbons in the Interstellar Medium: The Aliphatic C--D Band Strengths
X. J. Yang, Aigen Li
Deuterium (D) was exclusively generated in the Big Bang and the standard Big Bang Nucleosynthesis (BBN) model predicts a primordial abundance of D/H~26ppm. As the Galaxy evolves, D…
Aliphatics and Aromatics in the Universe: The Pre-JWST Era
X. J. Yang, Aigen Li
The so-called "unidentified infrared emission" (UIE) features at 3.3, 6.2, 7.7, 8.6, and 11.3 micron ubiquitously seen in a wide variety of astrophysical regions are generally attr…
Towards a reliable prediction of the infrared spectra of cosmic fullerenes and their derivatives in the JWST era
Jianzhi Xu, Aigen Li, Xiaohu Li +1
Fullerenes, including C60, C70, and C60+, are widespread in space through their characteristic infrared vibrational features (C60+ also reveals its presence in the interstellar med…
Spatially resolving polycyclic aromatic hydrocarbons in Herbig Ae disks with VISIR-NEAR at the VLT
Gideon Yoffe, Roy van Boekel, Aigen Li +15
We use the long-slit spectroscopy mode of the VISIR-NEAR experiment to perform diffraction-limited observations of eight nearby Herbig Ae protoplanetary disks. We extract spectra f…
