ULX, or ultraluminous X-ray sources, are objects that give off hundreds to thousands of times more X-rays than typical binary systems where a star is orbiting a black hole or neutron star.
The more surprising result comes from Matteo Bachetti (University of Toulouse, France) and colleagues, who detected pulsations from another ULX in the galaxy M82, proving it's not a black hole at all, but a pulsar.
"Our observations tell us that this ULX source - and by extension, many others - is just a run-of-the-mill black hole, only about 10 times the mass of the sun, that is swallowing material as fast as it can."
X-ray telescopes have shown many nearby galaxies to host ULX sources, which can be bright enough to outshine an entire galaxy in X-rays.
The intriguing new ULX is located in M83, a spiral galaxy about 15 million light years from Earth, discovered in 2010 with Chandra.
The Durham-led findings link the ULX spotted in Andromeda to a normal stellar black hole formed after a massive star exploded as a supernova.
Maxiva ULX transmitters are equipped with the Harris Apex M2X exciter, which enables analogue broadcasters the transition to digital via a simple software update.
In the fringes of the galaxy NGC 1399 lies a globular cluster containing an ultraluminous X-ray source (ULX) thought to be a black hole with a few thousand times the mass of the Sun--a much-sought "intermediate-mass" black hole.
GatesAir Maxiva ULX liquid-cooled UHF transmitters were selected for both phases.
Another ULX containing a volatile, old black hole recently was discovered in the Andromeda galaxy by Amanpreet Kaur, from Clemson University, and colleagues and published in the February 2012 issue of Astronomy and Astrophysics.
