TL;DR: GRAVITY as mentioned in this paper is a new instrument to coherently combine the light of the European Southern Observatory Very Large Telescope Interferometer to form a telescope with an equivalent 130 m diameter angular resolution and a collecting area of 200 m$^2$.

The origins of X-ray emission from the hot spots of FR II radio sources
TL;DR: In this paper, the authors used new and archival Chandra data to investigate the X-ray emission from a large sample of compact hot spots of FR II radio galaxies and quasars from the 3C catalog.

Chandra Observations of Cygnus A: Magnetic Field Strengths in the Hot Spots of a Radio Galaxy
TL;DR: In this paper, Chandra X-ray observations of the powerful radio galaxy Cygnus A with the X-Ray Observatory were reported, showing that the magnetic field in each of the brighter hot spots is 1.5 × 10^(-4) G, with an uncertainty of a few tens of percent.
Journal ArticleDOI
Magnetic Energy of the Intergalactic Medium from Galactic Black Holes
TL;DR: In this article, the authors present a quantitative analysis of two radio source samples having opposite extremes of ambient gas density that leads to important new conclusions about the magnetic energy in the intergalactic medium (IGM).
