The ordering of the neutrino masses is a crucial input for a deep understanding of flavor
physics, and its determination may provide the key to establish the relationship among the …

The study of galaxy protoclusters is beginning to fill in unknown details of the important
phase of the assembly of clusters and cluster galaxies. This review describes the current …

Abstract The Hydrogen Epoch of Reionization Array (HERA) is a staged experiment to
measure 21 cm emission from the primordial intergalactic medium (IGM) throughout cosmic …

The Square Kilometre Array (SKA) is a planned large radio interferometer designed to
operate over a wide range of frequencies, and with an order of magnitude greater sensitivity …

The formation of the first galaxies during cosmic dawn and reionization (at redshifts z= 5–
30), triggered the last major phase transition of our universe, as hydrogen evolved from cold …

We present the first limits on the Epoch of Reionization 21 cm H i power spectra, in the
redshift range z= 7.9–10.6, using the Low-Frequency Array (LOFAR) High-Band Antenna …

The properties of the first galaxies, expected to drive the Cosmic Dawn and the Epoch of
Reionization, are encoded in the 3D structure of the cosmic 21-cm signal. Parameter …

We present limits on the 21 cm power spectrum from the Epoch of Reionization using data
from the 64 antenna configuration of the Donald C. Backer Precision Array for Probing the …

If dark matter is composed of axions, then axion stars form in the cores of dark matter halos.
These stars are unstable above a critical mass, decaying to radio photons that heat the …

Observations of the redshifted 21-cm line of atomic hydrogen have provided several upper
limits on the 21-cm power spectrum and a tentative detection of the sky-averaged signal at …
