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,

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
