GW 170817 and it's non-thermal emission

 

Abstract

The detection of gravitational waves, gamma-rays, and multi wavelength radiation from the binary neutron star merger GW170817 has been an enormous breakthrough in astrophysics. It has confirmed some theoretical expectations and opened new riddles. I will extensively introduce the observations and physics of the event and then concentrate on the non-thermal component of the emission and on the possible the association of binary neutron star mergers with short-duration gamma-ray bursts. I will show that the most likely scenario is the one in which GW170817 produced a canonical short gamma-ray burst jet that was misaligned with our line of sight, resulting in unusual behavior. I will finally discuss the prospect for the incoming O3 observation period of LIGO.


 

Connect with NRAO

The National Radio Astronomy Observatory and Green Bank Observatory are facilities of the U.S. National Science Foundation operated under cooperative agreement by Associated Universities, Inc.

Founded in 1956, the NRAO provides state-of-the-art radio telescope facilities for use by the international scientific community. NRAO telescopes are open to all astronomers regardless of institutional or national affiliation. Observing time on NRAO telescopes is available on a competitive basis to qualified scientists after evaluation of research proposals on the basis of scientific merit, the capability of the instruments to do the work, and the availability of the telescope during the requested time. NRAO also provides both formal and informal programs in education and public outreach for teachers, students, the general public, and the media.

The National Science Foundation (NSF) is an independent federal agency created by Congress in 1950 "to promote the progress of science; to advance the national health, prosperity, and welfare; to secure the national defense..."

AUI collaborates with the scientific community and research sponsors to plan, build, and operate cutting-edge facilities. We cultivate excellence, deliver value, enhance education, and engage the public.
