Black Hole

Light curve of the gamma-ray flare (bottom) and collection of quasi-simulated images of the M87 jet (top) at various scales obtained in radio and X-ray during the 2018 campaign. The instrument, the wavelength observation range and scale are shown at the top left of each image.

Massive Black Hole in M87 Unleashes First Gamma-ray Flare in Over a Decade

Using the deepest X-ray image ever made with Chandra of Centaurus A, astronomers have found an unusual mark from the giant black hole’s powerful jet striking an unidentified object in its path. A patch of V-shaped emission connected to a bright source of X-rays is located close to the path of the jet from the supermassive black hole (highlighted in the inset). The arms of the “V” are at least about 700 light-years long. In this image, low, medium, and high-energy X-rays from Chandra are colored pink, purple, and blue respectively.

This is an artist's concept looking down into the core of the giant elliptical galaxy M87. A supermassive black hole ejects a 3,000-light-year-long jet of plasma, traveling at nearly the speed of light. In the foreground, to the right is a binary star system. The system is far from the black hole, but in the vicinity of the jet. In the system an aging, swelled-up, normal star spills hydrogen onto a burned-out white dwarf companion star. As the hydrogen accumulates on the surface of the dwarf, it reaches a tipping point where it explodes like a hydrogen bomb. Novae frequently pop-off throughout the giant galaxy of 1 trillion stars, but those near the jet seem to explode more frequently. So far, it's anybody's guess why black hole jets enhance the rate of nova eruptions.

An artist’s impression of the system assuming that the massive companion star is a black hole. The brightest background star is its orbital companion, the radio pulsar PSR J0514-4002E. The two stars are separated by 8 million km and orbit each other every 7 days.

The Hubble Space Telescope has captured an image of an object in the ultraviolet part of the spectrum, which appears similar in size to our Milky Way. Researchers have been puzzled by this object for some time, but recently found similarities between it and a nearby galaxy known as IC 5249, which lacks a bulge and is observed edge-on. The images in ultraviolet and visible light of both objects are strikingly similar and suggest that the object could be a galaxy without a bulge viewed edge-on. Credit for the images goes to HST.
