The early star-forming Universe is still poorly constrained, with the properties of high-redshift
stars, the first heating sources and reionization highly uncertain. This leaves observers …

We investigate the hypothesis that Coulomb-type interactions between dark matter (DM) and
baryons explain the anomalously low 21 cm brightness-temperature minimum at redshift z∼ …

cm Signal - IOPscience This site uses cookies. By continuing to use this site you agree to our …

The birth of the first luminous sources and the ensuing epoch of reionization are best studied
via the redshifted 21-cm emission line, the signature of the first two imprinting the last. In this …

We build a new model for the global 21-cm signal that is calibrated to measurements of the
high-z galaxy luminosity function (LF) and further tuned to match the Thomson scattering …

Long-wavelength spectral distortions in the cosmic microwave background arising from the
21 cm transition in neutral hydrogen are a key probe of the Cosmic Dawn and the Epoch of …

ABSTRACT The EDGES High-Band experiment aims to detect the sky-average brightness
temperature of the 21 cm signal from the epoch of reionization in the redshift range …

ABSTRACT Global (ie sky-averaged) 21-cm signal experiments can measure the evolution
of the Universe from the cosmic dawn to the epoch of reionization (EoR). These …

We investigate the effects of Population III stars on the sky-averaged 21-cm background
radiation, which traces the collective emission from all sources of ultraviolet and X-ray …

We report the spectral index of diffuse radio emission between 50 and 100 MHz from data
collected with two implementations of the Experiment to Detect the Global EoR Signature …
