Title: GW190425: Observation of a Compact Binary Coalescence with Total Mass ~3.4 Msun
Abstract: On April 25 2019 the LIGO-Virgo gravitational-wave observatory network observed their second binary neutron star merger. The source frame chirp mass (1.44 solar masses) and total mass (3.3 - 3.6 solar masses) are significantly larger than those of any known binary neutron star system. In this talk we will discuss this new discovery from the LIGO-Virgo observatories. We will describe the methods by which such sources are observed and characterized and discuss particular challenges for GW190425. Finally we will discuss the astrophysical implications of this observation and the [lack of] counterpart electromagnetic observations.
