Using data from the Rossi X-ray Timing Explorer (RXTE) satellite, astronomers from the Florida Institute of Technology have discovered a quasi-periodic oscillation (QPO) in the galaxy NGC 4945. The finding, reported in a ...
An active galactic nucleus (AGN) is a supermassive black hole residing at the core of a galaxy that is accreting material. The accretion occurs in the vicinity of the hot torus around the nucleus, and it can generate rapidly ...

The galactic magnetic field plays an important role in the evolution of the galaxy, but its small-scale behaviour is still poorly known. It is also unknown whether it permeates the halo of the galaxy or not. By using observations ...

Most galaxies host supermassive black holes at their nuclei, each with millions or billions of solar-masses of material. There is thought to be a torus of dust and gas around the black holes, and an accreting disk that becomes ...
