    The fraction of dark matter within galaxies from the IllustrisTNG simulations 
    Lovell, Mark; Pillepich, Annalisa; Genel, Shy; Nelson, Dylan; Springel, Volker; Pakmor, Rüdiger; Marinacci, Federico; Weinberger, Rainer; Torrey, Paul; Vogelsberger, Mark; Alabi, Adebusola; Hernquist, Lars (Oxford University Press (OUP), 2018-08-25)
    We use the IllustrisTNG (TNG) cosmological simulations to provide theoretical expectations for the dark matter mass fractions (DMFs) and circular velocity profiles of galaxies. TNG predicts flat circular velocity curves for z = 0 Milky Way (MW)-like ...

    Galaxies through cosmic time illuminated by gamma-ray bursts and quasars 
    Elm Heintz, Kasper (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2019-07)
    In the early Universe, most of the cold neutral gas that will later form into individual stars and galaxies is practically invisible to us. These neutral gas reservoirs can, however, be illuminated by bright cosmic lightsources such as gamma-ray bursts ...

    Observational constraints on secret neutrino interactions from big bang nucleosynthesis 
    Huang, Guo-yuan; Ohlsson, Tommy; Zhou, Shun (American Physical Society (APS), 2018-04-05)
    We investigate possible interactions between neutrinos and massive scalar bosons via g ϕ ¯ ν ν ϕ (or massive vector bosons via g V ¯ ν γ μ ν V μ ) and explore the allowed parameter space of the coupling constant g ϕ (or g V ) ...

    The structure and assembly history of cluster-sized haloes in self-interacting dark matter 
    Brinckmann, Thejs; Zavala Franco, Jesus; Rapetti, David; Hansen, Steen H.; Vogelsberger, Mark (Oxford University Press (OUP), 2017-10-30)
    We perform dark-matter-only simulations of 28 relaxed massive cluster-sized haloes for cold dark matter (CDM) and self-interacting dark matter (SIDM) models, to study structural differences between the models at large radii, where the impact of baryonic ...

    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 ...
