Magnetar near Galactic Centre supermassive black hole delivers surprises

16 May 2015 Astronomy Now

Magnetars are dense, collapsed stars that possess enormously powerful magnetic fields. At a distance that could be as small as 0.3 light-years from the 4-million-solar mass black hole in the centre of our Milky Way galaxy, magnetar SGR 1745-2900 is by far the closest neutron star to a supermassive black hole ever discovered and is likely in its gravitational grip.
