Gravitational Waves and Gamma-Rays from a Binary Neutron Star Merger: GW170817 and GRB 170817A
On 2017 August 17, the gravitational-wave event GW170817 was observed by the Advanced LIGO and Virgo detectors, and the gamma-ray burst (GRB) GRB 170817A was observed independently by the FermiExpand

An unusual supernova in the error box of the γ-ray burst of 25 April 1998
We report the discovery of transient optical emission in the error box of the γ-ray burst GRB980425, the light curve of which was very different from that of previous optical afterglows associated with β�-ray bursts. Expand

Dynamical Evidence for a Black Hole in the Microquasar XTE J1550-564
Optical spectroscopic observations of the companion star (type G8 IV to K4 III) in the microquasar system XTE J1550-564 reveal a radial velocity curve with a best-fitting spectroscopic period of PspExpand

Complete and Simultaneous Spectral Observations of the Black-Hole X-ray Nova XTE J1118+480
The X-ray nova XTE J1118+480 suffers minimal extinction (b = 62 degrees) and therefore represents an outstanding opportunity for multiwavelength studies. Hynes et al. (2000) conducted the first suchExpand

SDSS unveils a population of intrinsically faint cataclysmic variables at the minimum orbital period
We discuss the properties of 137 cataclysmic variables (CVs) which are included in the Sloan Digital Sky Survey (SDSS) spectroscopic data base, and for which accurate orbital periods have beenExpand

Hubble Space Telescope Parallaxes of AM CVn Stars and Astrophysical Consequences
We present absolute parallaxes and relative proper motions for five AM CVn stars, which we obtained using the Fine Guidance Sensors on board the Hubble Space Telescope. Our parallax measurementsExpand

The radio-to-X-Ray spectrum of GRB 970508 on 1997 May 21.0 UT
We have reconstructed the spectrum of the afterglow of GRB 970508 on 1997 May 21.0 UT (12.1 days after the gamma-ray burst) on the basis of observations spanning the X-ray-to-radio range. TheExpand

Tests of General Relativity with the Binary Black Hole Signals from the LIGO-Virgo Catalog GWTC-1.
The detection of gravitational waves by Advanced LIGO and Advanced Virgo provides an opportunity to test general relativity in a regime that is inaccessible to traditional astronomical observationsExpand
