Lyman Continuum Leakage from Massive Leaky Starbursts: A Different Class of Emitters?

open access: yesThe Astrophysical Journal
The origin of Lyman continuum (LyC) photons responsible for reionizing the Universe remains largely unknown, with the fraction of escaping LyC photons from galaxies at z  ∼ 6 to 12 still uncertain.

A Model for Cosmic Magnetic Field Amplification: Effects of Pressure Anisotropy Perturbations

open access: yesUniverse
Magnetic field amplification in the early universe is a long-standing problem that has been extensively studied through theoretical and numerical approaches, focusing on turbulent dynamos and the growth of collisionless plasma instabilities.

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

open access: yesThe 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.
