Jet Breaks and Energetics of Swift Gamma-Ray Burst X-Ray Afterglows
We present a systematic temporal and spectral study of all Swift-X-ray Telescope observations of gamma-ray burst (GRB) afterglows discovered between 2005 January and 2007 December. After constructingExpand

Introducing the CTA concept
The Cherenkov Telescope Array (CTA) is a new observatory for very high-energy (VHE) gamma rays. CTA has ambitions science goals, for which it is necessary to achieve full-sky coverage, to improve theExpand

A Deep Chandra X-ray Study of Neutron Star Coalescence GW170817
We report Chandra observations of GW170817, the first neutron star-neutron star merger discovered by the joint LIGO-Virgo Collaboration, and the first direct detection of gravitational radiationExpand

The prompt-afterglow connection in gamma-ray bursts: a comprehensive statistical analysis of Swift X-ray light curves
We present a comprehensive statistical analysis of Swift X-ray light-curves of GammaRay Bursts (GRBs) collecting data from more than 650 GRBs discovered by Swift and other facilities. TheExpand

Why Do Some Intermediate Polars Show Soft X-Ray Emission? A Survey of XMM-Newton Spectra
TLDR
We make a systematic analysis of the XMM-Newton X-ray spectra of intermediate polars (IPs) and find that, contrary to the traditional picture, most show a soft blackbody component. Expand

Brightening X-Ray Emission from GW170817/GRB 170817A: Further Evidence for an Outflow
The origin of the X-ray emission from neutron star coalescence GW170817/GRB 170817A is a key diagnostic of the unsettled post-merger narrative, and different scenarios predict distinct evolution inExpand

The 2016 super-Eddington outburst of SMC X-3: X-ray and optical properties and system parameters
On 2016 July 30 (MJD 57599), observations of the Small Magellanic Cloud by Swift/XRT found an increase in X-ray counts coming from a position consistent with the Be/X-ray binary pulsar SMC X-3.Expand
