The Cosmic Evolution of C IV Absorbers at 1.4 < z < 4.5: Insights from 100,000 Systems in DESI Quasars

The Astrophysical Journal
We present the largest catalog to date of triply ionized carbon (C iv ) absorbers detected in quasar spectra from the Dark Energy Spectroscopic Instrument.

The Cosmic Evolution and Spatial Distribution of Multiphase Gas Associated with QSOs

The Astrophysical Journal Letters
We investigate the multiphase gas surrounding QSOs traced by 33 absorption lines (e.g., Ly α , C iv , Fe ii , Mg ii , etc.) in the stacked spectra of background sources, using the Early Data Release from the Dark Energy Spectroscopic Instrument.

MUSEQuBES: Connecting H i Absorption with Lyα Emitters at z ≈ 3.3

The Astrophysical Journal
We present a comprehensive analysis of H i absorption around 96 Ly α emitters (LAEs) at z  ≈ 3.3 (median Ly α luminosity ≈10 ^42 erg s ^−1 ). These LAEs were identified within eight MUSE fields, each $1^{\prime} \times 1^{\prime} $ on the sky and ...

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
