Before the end of the Epoch of Reionization, the Hydrogen in the Universe was predominantly neutral. This leads to a strong attenuation of Ly alpha lines of z greater than or similar to 6 galaxies in the intergalactic medium. Nevertheless, Ly alpha h

In this work we investigate the properties of the sources that reionized the intergalactic medium (IGM) in the high-redshift Universe. Using a semi-analytical model aimed at reproducing galaxies and black holes in the first 1.5 Gyr of the Universe, w

The brightest galaxies at Cosmic Dawn

Autor: Charlotte A Mason, Michele Trenti, Tommaso Treu

Publikováno v: Mason, C A, Trenti, M & Treu, T 2023, ' The brightest galaxies at cosmic dawn ', Monthly Notices of the Royal Astronomical Society, vol. 521, no. 1, pp. 497-503 . https://doi.org/10.1093/mnras/stad035

Recent JWST observations suggest an excess of $z\gtrsim10$ galaxy candidates above most theoretical models. Here, we explore how the interplay between halo formation timescales, star formation efficiency and dust attenuation affects the properties an

The 21 cm bispectrum during reionization: a tracer of the ionization topology

Autor: Pratika Dayal, Darren J. Croton, Jacob Seiler, Catherine A. Watkinson, Anne Hutter, Manodeep Sinha

Publikováno v: Monthly Notices of the Royal Astronomical Society, 492(1), 653-667. Oxford University Press
Monthly Notices of the Royal Astronomical Society

We compute the bispectra of the 21cm signal during the Epoch of Reionization for three different reionization scenarios that are based on a dark matter N-body simulation combined with a self-consistent, semi-numerical model of galaxy evolution and re

Publikováno v: Bouwens, R J, Illingworth, G D, van Dokkum, P G, Oesch, P A, Stefanon, M & Ribeiro, B 2022, ' Sizes of Lensed Lower-luminosity z=4-8 Galaxies from the Hubble Frontier Field Program ', Astrophysical Journal, vol. 927, no. 1, 81 . https://doi.org/10.3847/1538-4357/ac4791
The Astrophysical Journal, 927(1):81

We constrain the rest-UV size-luminosity relation for star-forming galaxies at z~4 and z~6, 7, and 8 identified behind clusters from the Hubble Frontier Fields (HFF) program. The size-luminosity relation is key to deriving accurate luminosity functio
