Deuterated Polycyclic Aromatic Hydrocarbons in the Interstellar Medium: Constraints from the Orion Bar as Observed by the James Webb Space Telescope
Xuejuan Yang, Aigen Li
The gas-phase abundances of deuterium (D) in the local interstellar medium (ISM) exhibit considerable regional variations. Particularly, in some regions the gas-phase D abundances…
What causes the ultraviolet extinction bump at the cosmic dawn?
Qi Li, Xuejuan Yang, Aigen Li
The enigmatic ultraviolet (UV) extinction bump at 2175 Angstrom, the strongest spectroscopic absorption feature superimposed on the interstellar extinction curve, has recently been…
Interstellar dust revealed by light from cosmic dawn
Xuejuan Yang, Aigen Li
The obscuration of light from a distant galaxy has raised the possibility that a type of carbon dust existed in the earliest epochs of the Universe -- challenging the idea that sta…
Unveiling the Aromatic and Aliphatic Universe at Redshifts 0.2--0.5 with JWST NIRCam/WFSS
Jianwei Lyu, Xuejuan Yang, Aigen Li +4
Utilizing deep NIRCam/WFSS data from JWST's FRESCO program, we spectroscopically survey the 3.3 aromatic and 3.4 aliphatic C--H stretching emission bands of polycyclic ar…
