A SPectroscopic Survey of Biased Halos In the Reionization Era (ASPIRE): JWST Supports Earlier Reionization around [O iii] Emitters

The Astrophysical Journal
Understanding when and how reionization happened is crucial for studying the early structure formation and the properties of the first galaxies in the Universe. At z > 5.5, the observed intergalactic medium (IGM) optical depth shows a significant scatter,

Deep Learning–based Pseudocontinuum Fitting of C iv Emission-line Regions for High-quality Absorption-line Measurement

The Astrophysical Journal Supplement Series
Intrinsic associated absorption lines (AALs) in quasar spectra play a crucial role in providing insights into the chemical and physical properties of quasar outflows, host galaxies, and their surrounding interstellar medium. Affected by the complexity of

Tracing the Evolution of the Cool Gas in CGM and IGM Environments through Mg ii Absorption from Redshift z = 0.75 to z = 1.65 Using DESI-Y1 Data

The Astrophysical Journal
We present a measurement of the mean absorption of cool gas traced by Mg ii ( λλ 2796, 2803) around emission line galaxies (ELGs), spanning spatial scales from 20 kpc to 10 Mpc.

Subaru high-resolution spectroscopy of complex metal absorption lines of the quasar HS 1603+3820

Subaru high-resolution spectroscopy of complex metal absorption lines of the quasar HS 1603+3820
We present a high-resolution spectrum of the quasar HS 1603+ 3820 (z(em) = 2.542), observed with the High Dispersion Spectrograph on the Subaru Telescope. This quasar, first discovered in the Hamburg/CfA Quasar Survey, has 11 C IV lines at 1.96 < z(abs) < 2.55.
