First Submillimeter Lights from Dome A: Tracing the Carbon Cycle in the Feedback of Massive Stars

Yan Gong, Jiaqiang Zhong, Yuan Ren +38

The cycling of carbon between its ionized, atomic, and molecular phases shapes the chemical compositions and physical conditions of the interstellar medium (ISM). However, ground-b…

Tracking Outflow using Line-Locking (TOLL). II. Large Line-Locking Web identified in Quasar J151352+085555

Chen Chen, Zhicheng He, Weimin Yi +3

Quasar outflows often consist of two clouds with velocity separations matching the doublet spacings of common UV resonance transitions, a phenomenon known as line-locking, which is…

The 2175 Å~ Bump Features in FeLoBAL Quasars: One Indicator of MW-like Dust in the Nuclear Region of Quasar

Shaohua Zhang, Jian Ge, Tuo Ji +8

To investigate the properties of dust in the nuclear region of quasars, we explored the extinction curves of the iron low-ionization broad absorption line (FeLoBAL) quasar SDSS J16…
