H.; Jakobsson, Pall; Kouveliotou, C.; Laskar, T.; Levan, A. J.; Rossi, A. (EDP Sciences, 2020-09)
    Context. The identification of the sources that reionized the Universe and their specific contribution to this process are key missing pieces of our knowledge of the early Universe. Faint star-forming galaxies may be the main contributors to the ionizing ...

    X-ray background and its correlation with the 21 cm signal 
    Ma, Q; Ciardi, B; Eide, M B; Helgason, Kári (Oxford University Press (OUP), 2018-07-09)
    We use high-resolution hydrodynamical simulations to study the contribution to the X-ray background from high-z energetic sources, such as X-ray binaries, accreting nuclear black holes, and shock heated interstellar medium. Adopting the model discussed ...

    X-shooting GRBs at high redshift: probing dust production history 
    Zafar, T; Møller, P; Watson, D; Lattanzio, J; Hopkins, A M; Karakas, A; Fynbo, J P U; Tanvir, N R; Selsing, J; Jakobsson, Pall; Heintz, K E; Kann, D A; Groves, B; Kulkarni, V; Covino, S; D’Elia, V; Japelj, J; Corre, D; Vergani, S (Oxford University Press (OUP), 2018-07-19)
    Evolved asymptotic giant branch (AGB) stars and Type  Ia supernovae (SNe) are important contributors to the elements that form dust in the interstellar medium of galaxies, in particular, carbon and iron. However, they require at least a Gyr to start ...
