What Can We Learn about Reionization Astrophysical Parameters Using Gaussian Process Regression?

The Astrophysical Journal
Reionization is one of the least understood processes in the evolution history of the Universe, mostly because of the numerous astrophysical processes occurring simultaneously about which we do not have a very clear idea so far.

The THESAN project: Lyman-alpha emitters as probes of ionized bubble sizes

The Open Journal of Astrophysics
We use the THESAN radiation-hydrodynamics simulations to investigate how Lyman-$\alpha$ emitters (LAEs) trace ionized bubble sizes during the Epoch of Reionization.

Probing the Cosmic Reionization History with JWST: Gunn–Peterson and Lyα Damping Wing Absorption at 4.5 < z < 13

The Astrophysical Journal
We present a statistical analysis of Ly α absorption using 581 galaxies at z = 4.5–13 observed with multiple JWST/NIRSpec spectroscopy programs, including JADES, UNCOVER, CEERS, and GO/DDT. We carefully construct composite spectra binned by redshift with

Cross-correlating the Patchy Screening and Kinetic Sunyaev–Zel’dovich Effects as a New Probe of Reionization

The Astrophysical Journal
The kinetic Sunyaev–Zel’dovich effect (kSZ) and patchy screening effect are two complementary cosmic microwave background (CMB) probes of the reionization era.

Cosmic Reionization in the JWST Era: Back to AGNs?

The Astrophysical Journal
Deep surveys with the James Webb Space Telescope (JWST) have revealed an emergent population of moderate-luminosity, broad-line active galactic nuclei (AGNs) at 4 ≲ z ≲ 13 powered by accretion onto early massive black holes.

On the Properties of Cosmological Ionization Fronts

The Astrophysical Journal
We investigate the properties of cosmological ionization fronts during the epoch of reionization using the Cosmic Reionization on Computers simulations. By analyzing reionization timing maps, we characterize ionization front velocities and curvatures and
