“Invisible Monsters” –Supermassive Black Holes Roam the Milky Way 

 

Supermassive Black Hole

 

Astronomers are beginning to understand what happens when black holes get the urge to roam through the Milky Way. Typically, a supermassive black hole (SMBH) exists at the core of a massive galaxy. But sometimes SMBHs may “wander” throughout their host galaxy, remaining far from the center in regions such as the stellar halo, a nearly spherical area of stars and gas that surrounds the main section of the galaxy.

“At the Edge of Spacetime” –Strange Star S2 Orbiting Milky Way’s Supermassive Black Hole

Sgr*A Simulation

 

On March 2, 2019, astronomers reported discovery of a dozen black holes gathered around Sagittarius A* (Sgr A*), the supermassive monster in the center of the Milky Way Galaxy, supporting a decades-old prediction. After conducting a cosmic inventory to calculate and categorize stellar-remnant black holes, the astronomers from the University of California concluded that there are probably tens of millions of the enigmatic, dark objects in the Milky Way – far more than expected.

Mystery of Black Hole Eruptions — “Their Cause Unknown”

Black Hole

 

Up until a beautiful May evening in 2019 at Hawaii’s Keck Observatory, Sagittarius A* (Sgr A*), the Milky Way’s central supermassive black hole was usually a passive flickering object that appeared like a massive, dormant volcano or a sleeping monster. But suddenly Sgr A*, located twenty-five thousand light years from Earth, brightened 75-fold. “The black hole is always variable,” observed astronomer Tuan Do, “but this was the brightest we’ve seen in the infrared so far. It was probably even brighter before we started observing that night!”

Monster Black Hole at the Beginning of the Universe –“Unseen Spinning Source of Creation”

Quasar J1007+2115

 

When the iconic black hole the size of our Solar System located at the center of the galaxy M87 was imaged in 2019, astronomers described it as witnessing the “gates of Hell and the end of spacetime.” Fast forward to today, astronomers using three Maunakea Observatories in Hawai’i describe the second-most distant quasar ever found at a cosmological redshift greater than 7.5, and it hosts a black hole twice as large as the other quasar known in the same era. They call this new quasar Pōniuā`ena, which means “unseen spinning source of creation, surrounded with brilliance” in the Hawaiian language. The light observed from Pōniuā`ena reached Earth 13 billion years after leaving the quasar just 700 million years after the Big Bang.

Astronomers Peer Through the Fog at Milky Way’s Supermassive Black Hole –“Is It Emitting a Jet Angled Toward Earth?”

 

Black Hole

 

In 2019 astronomers lifted the veil on the monster black hole called Sagittarius A* (Sgr A*) at the heart of our Milky Way Galaxy. Using computer modelling, the scientists simulated the material inside the thick cloud of plasma, dust and gas surrounding Sgr A*.  The results pointed to the possibility of a relativistic jet coming from the supermassive black hole with an inclination that is aligned with Earth’s viewing point.

A New State of Matter --"The Black Hole Physics of Strange Metals"

 

“Not only does God play dice but… he sometimes throws them where they cannot be seen,” said Stephen Hawking about the paradoxical physics of black Holes. Welcome to the bizarre quantum world of “strange metals” –a new state of matter.
