Neutron Star Merger Seen and Heard For
O ver thousands of years, astronomy has evolved from hand-drawn maps of the night sky to breathtaking telescope images of the far-away cosmos. Yet despite this advance in technology, most of our information about the Universe has come from photon messengers. This changed in September 2015 with the detection of gravitational waves from a black hole merger at the Laser Interferometer Gravitationa...
متن کاملThe Detectability of Orphan Afterglows
The realization that GRBs release a constant amount of energy implies that the post jet-break afterglow evolution would be largely universal. For a given redshift all afterglows should be detected up to a fixed observer angle. We estimate the observed magnitude and the implied detectability of orphan afterglows. We show that for reasonable limiting magnitudes (mlim = 25) orphan afterglows would...
متن کاملOn the Progenitor of Binary Neutron Star Merger GW170817
On 2017 August 17 the merger of two compact objects with masses consistent with two neutron stars was discovered through gravitational-wave (GW170817), gamma-ray (GRB170817A), and optical (SSS17a/AT 2017gfo) observations. The optical source was associated with the early-type galaxy NGC 4993 at a distance of just ∼40 Mpc, consistent with the gravitational-wave measurement, and the merger was lo...

متن کاملThe Galactic Double-Neutron-Star Merger Rate: Most Current Estimates
We summarize our results on the Galactic merger rate of double neutron stars (DNS) in view of the recent discovery of PSR J0737−3039. We also present previously unpublished results for the global probability distribution of merger rate values that incorporate the presently known systematics from the radio pulsar luminosity function. The most likely value obtained from the global distribution is...
