The objects causing these low - frequency ripples — such as orbiting supermassive black holes at the centers of distant galaxies — would be different from the higher frequency ripples, emitted by collisions of much smaller black holes, that have so far been detected on Earth.

After charting stars in the heart of our galaxy traveling at speeds up to 50 times faster than Earth circles the sun, scientists are convinced that a supermassive black hole is pulling the strings, as only the relentless grip of a supermassive black hole could keep these frenzied stars locked into orbit within the galactic center.

J1415 +1320 is what's known as a blazar, a bright galaxy with a gluttonous supermassive black hole at its center (SN: 3/4/17, p. 13).

A small fraction of supermassive black holes — the ginormous ones that lurk at the centers of galaxies — fire off light - speed jets of particles as they snack.

Beginning in 1998, their groups have independently produced compelling evidence for the once controversial notion that our galaxy has at its center a supermassive black hole which is about 4 million times as massive as the sun.

Researchers expect to directly measure this phenomenon beginning in the spring as S0 - 2 makes its closest approach to the supermassive black hole at the center of our Milky Way galaxy.

«The electrons that make up the cloud initially bounce off the supermassive black hole at the center of one of the galaxies and accelerate as a result.

The joint research team led by graduate student and JSPS fellow Takuma Izumi at the Graduate School of Science at the University of Tokyo revealed for the first time — with observational data collected by ALMA (Atacama Large Millimeter / submillimeter Array), in Chile, and other telescopes — that dense molecular gas disks occupying regions as large as a few light years at the centers of galaxies are supplying gas directly to the supermassive black holes.

Supermassive black holes lurk at the centers of galaxies, and when those galaxies collide, eventually their supermassive black holes will first slowly circle each other spiraling inward like water down a drain, then eventually meSupermassive black holes lurk at the centers of galaxies, and when those galaxies collide, eventually their supermassive black holes will first slowly circle each other spiraling inward like water down a drain, then eventually mesupermassive black holes will first slowly circle each other spiraling inward like water down a drain, then eventually merge as well.

The gas outflow driven by a supermassive black hole at the galactic center recently has become the focus of attention as it possibly is playing a key role in the co-evolution of galaxies and black holes.

VLBA images detect orbital motion of two supermassive black holes as they circle each other at the center of a distant galaxy.

The discovery was made as part of a program to detect supermassive black holes, millions or billions of times more massive than the Sun, that are not at the centers of galaxies.

The halos around quasars — the brightest and the most active objects in the universe, they are galaxies formed less than 2 billion years after the Big Bang; they have supermassive black holes in their centers and consume stars, gas, interstellar dust and other material at a very fast rate — are made of gas known as the intergalactic medium and extend for up to 300,000 light - years from the centers of the quasars.

From supermassive black holes at galactic centers to giant bursts of star formation to titanic collisions between galaxies, these discoveries allow astronomers to probe the current properties of galaxies as well as examine how they formed and developed.
