What
"Sagittarius A* (Sgr A* Black Hole) sits at the centre of our galaxy, 26,000 light-years from Earth. This black hole, which has a mass 4 million times that of the sun, is surrounded by a star cluster - the S stars - which reach mind-boggling speeds when they approach the hole."

"...to follow one particular star in the Sgr A* system - S2 - before and after it passed close to the black hole on 19 May 2018. GRAVITY achieved a resolution of 50 microarcseconds: the angle at which a tennis ball placed on the moon would be visible from Earth."

"The binary star system consists of a normal (reddish giant) star in orbit with a black hole. Material from the star falls towards the black hole and spirals inwards in an accretion disk, with powerful jets being launched from the inner regions close to the black hole. The key deal here is the rotation of the jet." By the International Centre for Radio Astronomy Research, ICRAR.

Researchers Create Virtual Reality Simulation of a Supermassive Black Hole

ASTROPHYSICS

Researchers have created a virtual reality simulation of a supermassive black hole,
BioMed Central, November 18, 2018.

MAIN POINTS

“The black hole at the centre of our galaxy, Sagittarius A*, has been visualised in virtual reality for the first time.”

"Our virtual reality simulation creates one of the most realistic views of the direct surroundings of the black hole and will help us to learn more about how black holes behave. Traveling to a black hole in our lifetime is impossible, so immersive visualizations like this can help us understand more about these systems from where we are.

Outreach Effort
“...the virtual reality simulation could help encourage the general public, including children, to take an interest in astrophysics.”

MAIN POINTS

A Lively Supercluster
"A billion light-years from Earth lies one of the universe’s most massive structures, a giant elliptical galaxy surrounded by a sprawling cluster of other galaxies known as Abell 2597. At the core of the central galaxy, a supermassive black hole is powering the cosmic equivalent of a monumental fountain, drawing in vast stores of cold molecular gas and spraying them back out again in an ongoing cycle."

Black Hole's Gas Lighting

New simulation sheds light on spiraling supermassive black holes,
NASA/Goddard Space Flight Center, October 2, 2018.

This research uses supercomputers to create a cool animation modeling the orbits of two supermassive black holes, a binary pair of black holes, that were brought together by an ancient collision of their two progenitor galaxies, as these gravitationally bound black holes drag the remnants of their remaining glactic dust and gas through its final forty revolutions, before merging.

DISCOVERY
"...the discovery of...12 stellar-mass black holes, identified via X-ray data near our galaxy’s center."

"The Milky Way is really the only galaxy we have where we can study how supermassive black holes interact with little ones because we simply can’t see their interactions in other galaxies."

THE SEARCH
"The researchers used Chandra data to search for X-ray binaries – systems where a black hole is locked in a close orbit with a star and is pulling matter from the star, resulting in X-ray emission – near Sagittarius A*."

THE CENTER
Our "...galactic center is already known to be inhabited by a supermassive black hole, with some 4 million times the sun’s mass. Astronomers call this behemoth Sagittarius A."

National Institutes of Natural Sciences, February 13, 2018.

"The central region of M77 is an “active galactic nucleus,” or AGN, which means that matter is vigorously falling toward the central supermassive black hole and emitting intense light."

"The team imaged the area around the supermassive black hole in M77 and resolved a compact gaseous structure with a radius of 20 light-years."

Early Universe Surprises

Supermassive black hole is ahead of its time,
ASSOCIATION OF UNIVERSITIES FOR RESEARCH IN ASTRONOMY (AURA), December 6, 2017.

 

Main Points

690 Million Years After the Big Bang
(About 13.4 Billion Years Ago)
"The discovery of an extremely distant supermassive black hole, with a mass some 800 million times that of our Sun is causing astronomers to re-think our understanding of the early cosmos. Researchers report that this is the most distant giant black hole ever detected, and at this distance, our Universe was only about 5% of its current age, or about 690 million years after the Big Bang."

It's A Quasar
