Design concepts for the Cherenkov Telescope Array CTA: An advanced facility for ground-based high-energy gamma-ray astronomy

Marcos Daniel Actis, +685 more
TL;DR: The ground-based gamma-ray astronomy has had a major breakthrough with the impressive results obtained using systems of imaging atmospheric Cherenkov telescopes as mentioned in this paper, which is an international initiative to build the next generation instrument, with a factor of 5-10 improvement in sensitivity in the 100 GeV-10 TeV range and the extension to energies well below 100GeV and above 100 TeV.

A gravitational-wave standard siren measurement of the Hubble constant

B. P. Abbott, +1322 more
- 02 Nov 2017 - 
TL;DR: A measurement of the Hubble constant is reported that combines the distance to the source inferred purely from the gravitational-wave signal with the recession velocity inferred from measurements of the redshift using the electromagnetic data.
Journal ArticleDOI

An online repository of Swift/XRT light curves of Γ-ray bursts

TL;DR: In this paper, the authors present a suite of programs which automatically generate Swift /XRT light curves of GRBs, which can be used to provide the community with an online repository of X-ray light curves obtained with Swift.
