In addition to X-rays, gigantic black holes can also eject materials at high speeds to form jets. Many distant galaxies have been observed with such jets. Currently, scientists think that these galaxies have supermassive black holes (billions of solar masses) at their centers that produce the ...
This is seen, for instance, where black holes or neutron stars are in a close orbit such as this. In February 2016, gravitational waves were detected for the first time, 100 years after Einstein’s prediction. The waves emanated from the collision of two black holes, of 36 and 29 so...
The central ≈ 80×200 pc of the barred spiral galaxy M83 (NGC 5236) has been observed with the GEMINI-S+CIRPASS configuration which produced 490 spectra with a spectral resolving power of 3200, centered at 1.3 microns, oriented NW-SE. We determine the kinematics of this region with 0.36″...
黑洞是贪婪的食客 Black holes are voracious eaters. 它们将气体和尘埃拖入黑洞 They drag in gas and dust, 在黑洞周围形成物质环 which builds up in a ring of material around the black hole. 我们称之为吸积盘 We call this the accretion disk. 你可以把它想象成一个巨大的物质漩涡 You could think...
Astronomers have observed objects called quasars, which glow brighter than thousands of galaxies put together and are thought to be powered by supermassive black holes consuming matter. Quasars have been seen back as far as the first billion years after the Big Bang, when our universe formed, ...
The existence of the black hole can be determined on the basis of the stars close to black hole. Initially the concept of black hole was undetermined. But scientist observed different behavior of the stars present near the black hole. So, they named it as black hole....
Supermassive black holes, or SMBHs, are black holes with masses that are several million to billion times the mass of our sun. TheMilky Wayhosts an SMBH with a few million times the solar mass. Surprisingly, astrophysical observations show that SMBHs already existed when the universe was very...
Such objects include brown dwarfs, exceedingly dim white dwarfs, neutron stars and even black holes. MACHOs probably contribute somewhat to the dark matter mystery, but there are simply not enough of them to account for all of the dark matter in a single galaxy or cluster of galaxies. ...
23、hat wave.这两个碰撞的黑洞The colliding black holes are是LIGO迄今为止探测到的质量最大的the most massive LIGO hasever detected.一个是太阳质量的66倍One is 66 timesthe mass of our sun,另一个是太阳质量的85倍the other, 85 timesthe mass of our sun.普莱特:当两个黑洞盘旋而进入时PLAIT: As...
A White hole is just a theoretical mathematical concept and it hasn’t been observed in the universe. Most of the discussions of white holes revolve around the words “hypothetical”, “unfeasible”, and “unrealistic”. They are a potential solution to the laws of general relativity, which im...
