TL;DR: In this paper, ultraviolet and x-ray observations from the Nuclear Spectroscopic Telescope Array (NSTA) of the binary neutron star merger GW170817 were used to detect a high mass (≈0.03 solar masses) wind-driven outflow with moderate electron fraction.

TL;DR: In this article, a new analysis of 13 wide band BeppoSAX observations of the BL Lac object Mkn 421 is presented, where the energy distributions in different luminosity states can be fitted very well by a log-parabolic law, which provides good estimates of the energy and flux of the synchrotron peak in the SED.

TL;DR: In this paper, the gamma-ray activity of the high-synchrotron-peaked BL Lacertae object Markarian 421 (Mrk 421) during the first 1.5 years of Fermi operation was reported.

TL;DR: In this article, a piece-wise linear spline function was proposed to modify the vignetting response of the nuclear Spectroscopic Telescope Array (NuSTAR) X-ray satellite.

TL;DR: The Cherenkov Telescope Array (CTA) as mentioned in this paper is the major global observatory for very high energy gamma-ray astronomy over the next decade and beyond, covering a huge range in photon energy from 20 GeV to 300 TeV.
