Journal ArticleDOI
Magnetic focusing in the Sco X-1 radio source
TL;DR: In this article, it was shown that a sufficient overpressure with respect to the ambient interstellar medium can be achieved if the radius of the jet is reduced by a factor 10-100, and the converging flow becomes dissipative.
Journal ArticleDOI
Light bending and X-ray echoes from behind a supermassive black hole
Dan R. Wilkins,Luigi C. Gallo,Elisa Costantini,Elisa Costantini,W. N. Brandt,Roger Blandford +5 more
TL;DR: In this article, a relativistically broadened iron K line and Compton hump in the X-ray emission spectrum has been used to detect the re-emergence of X-rays from behind a supermassive black hole in I Zw 1.
Journal ArticleDOI
A variational formalism for tidal excitation: non-rotating, homentropic stars
TL;DR: In this article, a variational formalism for describing the dynamical evolution of an oscillating star with a point-mass companion in the linear, non-relativistic regime is presented.

TL;DR: The Supernova/Acceleration Probe (SNAP) as mentioned in this paper is a space-based experiment designed to study the dark energy and alternative explanations of the acceleration of the Universe's expansion by performing a series of complementary systematics-controlled astrophysical measurements.
