(American Astronomical Society, 2017-10-16)
    We report the discovery and monitoring of the near-infrared counterpart (AT2017gfo) of a binary neutron-star merger event detected as a gravitational wave source by Advanced Laser Interferometer Gravitational-wave Observatory (LIGO)/Virgo (GW170817) ...

    Highly ionized metals as probes of the circumburst gas in the natal regions of gamma-ray bursts 
    Elm Heintz, Kasper; Watson, D; Jakobsson, Pall; Fynbo, J P U; Bolmer, J; Arabsalmani, M; Cano, Zach; Covino, S; D’Elia, V; Gomboc, A; Japelj, J; Kaper, L; Krogager, J-K; Pugliese, G; Sánchez-Ramírez, R; Selsing, J; Sparre, M; Tanvir, N R; Thöne, C C; de Ugarte Postigo, A; Vergani, S D (Oxford University Press (OUP), 2018-06-04)
    We present here a survey of high-ionization absorption lines in the afterglow spectra of long-duration gamma-ray bursts (GRBs) obtained with the VLT/X-shooter spectrograph. Our main goal is to investigate the circumburst medium in the natal regions of ...

    Lyman continuum leakage in faint star-forming galaxies at redshift z = 3−3.5 probed by gamma-ray bursts 
    Vielfaure, J.-B.; Vergani, S. D.; Japelj, J.; Fynbo, J. P. U.; Gronke, M.; Elm Heintz, Kasper; Malesani, D. B.; Petitjean, P.; Tanvir, N. R.; D’Elia, V.; Kann, D. A.; Palmerio, J.

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 ...
