A Neutron Star Binary Merger Model for GW170817/GRB170817a/SSS17a
Ariadna Murguia-Berthier, Enrico Ramirez-Ruiz, Charles D. Kilpatrick +14
The merging neutron star gravitational wave event GW170817 has been observed throughout the entire electromagnetic spectrum from radio waves to -rays. The resulting energetics,…
Light Curves of the Neutron Star Merger GW170817/SSS17a: Implications for R-Process Nucleosynthesis
M. R. Drout, A. L. Piro, B. J. Shappee +41
On 2017 August 17, gravitational waves were detected from a binary neutron star merger, GW170817, along with a coincident short gamma-ray burst, GRB170817A. An optical transient so…
The Unprecedented Properties of the First Electromagnetic Counterpart to a Gravitational Wave Source
Matthew R. Siebert, Ryan J. Foley, Maria R. Drout +15
We discovered Swope Supernova Survey 2017a (SSS17a) in the LIGO/Virgo Collaboration (LVC) localization volume of GW170817, the first detected binary neutron star (BNS) merger, only…
The Old Host-Galaxy Environment of SSS17a, the First Electromagnetic Counterpart to a Gravitational Wave Source
Y. -C. Pan, C. D. Kilpatrick, J. D. Simon +16
We present an analysis of the host-galaxy environment of Swope Supernova Survey 2017a (SSS17a), the discovery of an electromagnetic counterpart to a gravitational wave source, GW17…
Electromagnetic Evidence that SSS17a is the Result of a Binary Neutron Star Merger
Charles D. Kilpatrick, Ryan J. Foley, Daniel Kasen +18
11 hours after the detection of gravitational wave source GW170817 by the Laser Interferometer Gravitational-Wave Observatory and Virgo Interferometers, an associated optical trans…
Hydrogen-Poor Superluminous Supernovae from the Pan-STARRS1 Medium Deep Survey
R. Lunnan, R. Chornock, E. Berger +31
We present light curves and classification spectra of 17 hydrogen-poor superluminous supernovae (SLSNe) from the Pan-STARRS1 Medium Deep Survey (PS1 MDS). Our sample contains all o…
