Latest Supermassive black holes Stories
These black holes are always hungry and are huge! Constantly gorging yourself on gas 'donuts' can do that to you.
Braaaaaains. A mysterious high-energy X-ray signal detected by NuSTAR could be the sounds of “zombie” stars feeding on the “brains” of nearby stellar companions, according to research published recently in the journal Nature.
Dartmouth astrophysicists and their colleagues have not only proven that a supermassive black hole exists in a place where it isn't supposed to be, but in doing so have opened a new door to what things were like in the early universe.
As two galaxies enter the final stages of merging, scientists have theorized that the galaxies’ supermassive black holes will form a “binary,” or two black holes in such close orbit they
These phantom quasars are brighter than they should be, what's going on? Hint: it's not aliens.
Observational evidence supports a functional link predicted by theory College Park, MD (PRWEB) March 25, 2015 Many nearby galaxies blast huge, wide-angled
WASHINGTON, March 4, 2015 /PRNewswire-USNewswire/ -- Using NASA's Chandra X-ray Observatory, astronomers have found that the growth of galaxies containing supermassive black holes can be slowed
The largest and most luminous black hole ever seen has been discovered, with a mass about 12 billion times that of the sun.
Every massive galaxy has a black hole at its center, and the heftier the galaxy, the bigger its black hole. But why are the two related? After all, the black hole is millions of times smaller and less massive than its home galaxy.
Someone dimmed the lights in space. Scientists observe a dimming quasar for the first time ever, and this could lead to a understanding of the mysterious black holes and their lifespans.
Supermassive Black Hole -- A Supermassive black hole is a black hole with a mass in the range of millions or billions solar masses. A supermassive black hole has some interesting properties differing from his low-mass cousins: -- The average density of a supermassive black hole can be very low, and actually can be lower than water's density. This happens because the black hole diameter increases linearly with mass, and consequently density drops much faster. -- Strong tidal...
Seyfert Galaxy -- Seyfert galaxies are spiral or irregular galaxies containing an extremely bright nucleus, most likely caused by a supermassive black hole, that can sometimes outshine the surrounding galaxy. The light from the central nucleus varies in less than a year, which implies that the emitting region must be less than one light year across. They are named for the astronomer Carl Seyfert, who studied them extensively in the 1940s. They are a subclass of active galactic nuclei....
Quasar -- A quasar (from quasi-stellar radio source) is an astronomical object that looks like a star in optical telescopes (i.e. it is a point source), but has a very high redshift. The general consensus is that this high redshift is cosmological, the result of Hubble's law and that their redshift indicates that they are typically very distant from Earth; we observe them as they were several billions of years ago. Since we can see them despite their distance, they must emit more...
