Galaxy formation is at the heart of our understanding of cosmic evolution. Although there is a
consensus that galaxies emerged from the expanding matter background by gravitational …

Indirect searches for dark matter are based on detecting an anomalous flux of photons,
neutrinos or cosmic-rays produced in annihilations or decays of dark matter candidates …

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 …

Abstract Recently, the Hydrogen Epoch of Reionization Array (HERA) has produced the
experiment's first upper limits on the power spectrum of 21 cm fluctuations at z∼ 8 and 10 …

We compute cosmic microwave background (CMB) anisotropy constraints on exotic forms of
energy injection in electromagnetic (em) channels over a large range of timescales. We …

While astrophysical and cosmological probes provide a remarkably precise and consistent
picture of the quantity and general properties of dark matter, its fundamental nature remains …

We calculate the post-recombination contribution to the cosmic microwave background
(CMB) spectral distortion due to general exotic energy injections, including dark matter (DM) …

The cosmic 21 cm signal is set to revolutionize our understanding of the early Universe,
allowing us to probe the 3D temperature and ionization structure of the intergalactic medium …

Dark matter energy injection in the early universe modifies both the ionization history and
the temperature of the intergalactic medium. In this work, we improve the CMB bounds on …

Measurements of the temperature of the baryons at the end of the cosmic dark ages can
potentially set very precise constraints on energy injection from exotic sources, such as …
