D; Svinkin, D; Thone, C. C; de Ugarte Postigo, A; Urata, Y; Weinstein, A (IOP Publishing, 2015-06)
    The Fermi Gamma-ray Space Telescope has greatly expanded the number and energy window of observations of gamma-ray bursts (GRBs). However, the coarse localizations of tens to a hundred square degrees provided by the Fermi ...

    The many unusual properties of the enigmatic AT2018cow suggested that at least some subset of the empirical class of fast blue optical transients (FBOTs) represents a genuinely new astrophysical phenomenon. Unfortunately, ...
  • Science with a Wide-Field UV Transient Explorer 
    Sagiv, I; Gal-Yam, A; Ofek, E. O; Waxman, E; Aharonson, O; Kulkarni, S. R; Nakar, E; Maoz, D; Trakhtenbrot, B; Phinney, E. S; J. Topaz, J; Beichman, C; Murthy, J; Worden, S. P (IOP Publishing, 2014-04)
    The time-variable electromagnetic sky has been well-explored at a wide range of wavelengths. In contrast, the ultra-violet (UV) variable sky is relatively poorly explored, even though it offers exciting scientific prospects. ...

M; Srivastav, S; Sullivan, M; Suntzeff, N. B; Surace, J; Wozniak, P. R; Yaron, O (EDP Sciences, 2015-06)
    We present near-infrared (NIR) time-series spectroscopy, as well as complementary ultraviolet (UV), optical, and NIR data, of the Type Ia supernova (SN Ia) iPTF13ebh, which was discovered within two days from the estimated ...

    Tidal disruption events (TDEs) are bursts of electromagnetic energy that are released when supermassive black holes at the centres of galaxies violently disrupt a star that passes too close1. TDEs provide a window through ...
  • The X-Ray and Radio Loud Fast Blue Optical Transient AT2020mrf: Implications for an Emerging Class of Engine-driven Massive Star Explosions
