CONCERTO: Instrument and status [PDF]

open access: yesEPJ Web of Conferences
CONCERTO (CarbON CII line in post-rEionization and ReionizaTiOn) is a low-resolution Fourier transform spectrometer dedicated to the study of star-forming galaxies and clusters of galaxies in the transparent millimeter windows from the ground.

The Late Reionization of Filaments

open access: yes, 2009
We study the topology of reionization using accurate three-dimensional radiative transfer calculations post-processed on outputs from cosmological hydrodynamic simulations.

The galaxy-IGM connection in THESAN: the physics connecting the IGM Lyman-$α$ opacity and galaxy density in the reionization epoch

open access: yesThe Open Journal of Astrophysics
The relation between the Lyman-$\alpha$ effective optical depth of quasar sightlines ($\tau_\mathrm{los}$) and the distribution of galaxies around them is an emerging probe of the connection between the first collapsed structures and the IGM properties ...

Supersonic baryon-CDM velocities and CMB B-mode polarization

open access: yes, 2011
It has recently been shown that supersonic relative velocities between dark matter and baryonic matter can have a significant effect on formation of the first structures in the universe. If this effect is still non-negligible during the epoch of hydrogen

Lyα Emission at z = 7–13: Clear Evolution of Lyα Equivalent Width Indicating a Late Cosmic Reionization History

open access: yesThe Astrophysical Journal
We present the evolution of Ly α emission derived from 53 galaxies at z = 6.6–13.2, which have been identified by multiple JWST/NIRSpec spectroscopy programs of Early Release Science, General Observer, Director's Discretionary Time, and Guaranteed Time ...

On the contribution of dwarf galaxies to reionization of the Universe

open access: yesThe Open Journal of Astrophysics
We present estimates of the ultraviolet (UV) and Lyman continuum flux density contributed by galaxies of luminosities from $M_{\rm UV}\approx -25$ to $M_{\rm UV}=-4$ at redshifts $5\leq z\leq 10$ using a galaxy formation model that reproduces properties ...
