The transformation of cold neutral intergalactic hydrogen into a highly ionized warm plasma
marks the end of the cosmic dark ages and the beginning of the age of galaxies. The details …

The launch of the James Webb Space Telescope (JWST) in late 2021 marks a new start for
studies of galaxy formation at high redshift (z≳ 6) during the era of cosmic reionization …

We measure escape fractions, f esc, of ionizing radiation from galaxies in the sphinx suite of
cosmological radiation-hydrodynamical simulations of reionization, resolving haloes with …

We investigate constraints on cosmic reionization extracted from the Planck cosmic
microwave background (CMB) data. We combine the Planck CMB anisotropy data in …

During reionization, neutral hydrogen in the intergalactic medium (IGM) imprints a damping
wing absorption feature on the spectrum of high-redshift quasars. A detection of this …

We present observations with the Cosmic Origins Spectrograph (COS) onboard the Hubble
Space Telescope of five star-forming galaxies at redshifts in the range 0.2993–0.4317 and …

Determinations of the ultraviolet (UV) luminosity function of active galactic nuclei (AGN) at
high redshifts are important for constraining the AGN contribution to reionization and …

The polarized thermal emission from diffuse Galactic dust is the main foreground present in
measurements of the polarization of the cosmic microwave background (CMB) at …

We report the detection of the Lyman continuum (LyC) radiation of the compact star-forming
galaxy (SFG) J1154+ 2443 observed with the Cosmic Origins Spectrograph (COS) onboard …

We infer the evolution of the UV luminosities of galaxies in haloes of masses 10 10–10 11
M⊙ in the redshift range of z∼ 9–16 from the recent JWST data. Within the standard ΛCDM …
