Cosmic reionization history and dark matter scenarios

  title={Cosmic reionization history and dark matter scenarios},
  author={Isabella P Carucci and Pier Stefano Corasaniti},
  journal={Physical Review D},
We perform an analysis of the cosmic reionization in the standard cold dark matter (CDM) paradigm and in alternative dark matter scenarios. Building upon the work of Corasaniti et al., we predict the reionization history for CDM, for warm dark matter, late-forming dark matter and ultralight axion dark matter models which reproduce state-of-the-art measurements of the galaxy luminosity function at very high redshifts 6≤z≤10. To this purpose we adopt a reionization model parametrized in terms of… 

The Epoch of Reionization in Warm Dark Matter Scenarios

In this paper we investigate how the Reionization process is affected by early galaxy formation in different cosmological scenarios. We use a semi-analytic model with suppressed initial power spectra

Astroparticle Constraints from Cosmic Reionization and Primordial Galaxy Formation

We derived astroparticle constraints in different dark matter scenarios that are alternatives to cold dark matter (CDM): thermal relic warm dark matter, WDM; fuzzy dark matter, ψDM; self-interacting

If dark matter decay or annihilate, a large amount of energy and particles would be released into the cosmic plasma. Therefore, they could modify the thermal and ionization history of our universe,

Clues to the nature of dark matter from first galaxies

We use 38 high-resolution simulations of galaxy formation between redshift 10 and 5 to study the impact of a 3 keV warm dark matter (WDM) candidate on the high-redshift Universe. We focus our

Semi-analytic forecasts for JWST – IV. Implications for cosmic reionization and LyC escape fraction

Galaxies forming in low-mass haloes are thought to be primarily responsible for reionizing the Universe during the first billion years after the big bang. Yet, these haloes are extremely

Small-scale clumping of dark matter and the mean free path of ionizing photons at $z=6$

. Recently, the mean free path of ionizing photons in the z = 6 intergalactic medium (IGM) was measured to be very short, presenting a challenge to existing reionization models. At face value, the

Predictions for the abundance of high-redshift galaxies in a fuzzy dark matter universe

During the last decades, rapid progress has been made in measurements of the rest-frame ultraviolet (UV) luminosity function (LF) for high-redshift galaxies (z ≥ 6). The faint-end of the galaxy LF

A short introduction to reionization physics

The epoch of reionization probes the state of our universe when the very first stars formed and ionized the hydrogen atoms in the surrounding medium. Since the epoch has not yet been probed

A multi-messenger view of cosmic dawn: Conquering the final frontier

The epoch of Cosmic Dawn, when the first stars and galaxies were born, is widely considered as the final frontier of observational cosmology today. Mapping the period between Cosmic Dawn and the



Reionization and Galaxy Formation in Warm Dark Matter Cosmologies

We compare model results from a semi-analytic (merger-tree based) framework for high-redshift (z ≃ 5–20) galaxy formation against reionization indicators, including the Planck electron scattering

Warm Dark Matter and Cosmic Reionization

In models with dark matter made of particles with keV masses, such as a sterile neutrino, small-scale density perturbations are suppressed, delaying the period at which the lowest mass galaxies are

Galaxy UV-luminosity function and reionization constraints on axion dark matter

If the dark matter (DM) were composed of axions, then structure formation in the Universe would be suppressed below the axion Jeans scale. Using an analytic model for the halo mass function of a

Warm dark matter and the ionization history of the Universe

In warm dark matter scenarios structure formation is suppressed on small scales with respect to the cold dark matter case, reducing the number of low-mass halos and the fraction of ionized gas at

Constraints on dark matter scenarios from measurements of the galaxy luminosity function at high redshifts

We use state-of-the-art measurements of the galaxy luminosity function (LF) at z=6, 7, and 8 to derive constraints on warm dark matter (WDM), late-forming dark matter, and ultralight axion dark

Observational constraints on key-parameters of cosmic reionisation history

We discuss constraints on cosmic reionisation and their implications on a cosmic star formation rate (SFR) density ρSFR model; we study the influence of key-parameters such as the clumping factor of

Cold or warm? Constraining dark matter with primeval galaxies and cosmic reionization after Planck

Dark matter constitutes the great majority of the matter content in the Universe, but its microscopic nature remains an intriguing mystery, with profound implications for particle physics,

Cosmic Reionization and Early Star-forming Galaxies: a Joint Analysis of new Constraints From Planck and the Hubble Space Telescope

We discuss new constraints on the epoch of cosmic reionization and test the assumption that most of the ionizing photons responsible arose from high-redshift star-forming galaxies. Good progress has

The high-z universe confronts warm dark matter: Galaxy counts, reionization and the nature of dark matter

We use N-body simulations to show that high-redshift galaxy counts provide an interesting constraint on the nature of darkmatter, specificallywarm darkmatter (WDM), owing to the lack of early

Planck intermediate results - XLVII. Planck constraints on reionization history

We investigate constraints on cosmic reionization extracted from the Planck cosmic microwave background (CMB) data. We combine the Planck CMB anisotropy data in temperature with the low-multipole
