#THE BLACK MASSES MAP FOR FREE#

Jayasinghe and his team report the detection of 'The Unicorn' in a paper that's been accepted for publication in the journal Monthly Notices of the Royal Astronomical Society. 'I think the field is pushing toward this, to really map out how many low-mass, how many intermediate-mass and how many high-mass black holes there are, because every time you find one it gives you a clue about which stars collapse, which explode and which are in between,' he said in the statement. And the smaller the black hole, the smaller the impact.Д«ut efforts to find extremely low-mass black holes have increased significantly in recent years, Thompson said, so we could soon learn much more about these mysterious objects. Black holes famously gobble up everything, including light, so astronomers have traditionally detected them by noticing the impact they have on their surroundings (though we did recently get our first direct image of a black hole, thanks to the Event Horizon Telescope). Very few such super-lightweight black holes are known, because they're incredibly hard to find. That explanation, likely though it may be, is not set in stone 'The Unicorn' remains a black hole candidate at the moment. 'The simplest explanation is that it's a black hole - and in this case, the simplest explanation is the most likely one.' 'Just as the moon's gravity distorts the Earth's oceans, causing the seas to bulge toward and away from the moon, producing high tides, so does the black hole distort the star into a football-like shape with one axis longer than the other,' study co-author Todd Thompson, chair of Ohio State's astronomy department, said in a statement (opens in new tab). (For perspective: The supermassive black hole at the heart of our Milky Way galaxy packs about 4.3 million solar masses.) The team determined that the object doing the tugging is likely a black hole -В one harboring a mere three solar masses, based on details of the star's velocity and the light distortion.

Jayasinghe and his colleagues analyzed that big dataset and noticed something interesting: The red giant's light shifts in intensity periodically, suggesting that another object is tugging on the star and changing its shape.
