Black holes are a fascinating issue of science and analysis of these massive monsters continues.
Every galaxy has its monster black hole what’s lurking at the center, and it’s millions and billions of times more massive than the Sun. Some of them are known as active galactic nuclei or quasars, and they’re shining really bright across the universe, devouring surrounding gas.
Most of these black holes are dormant, and they’re basically lurking invisibly for thousands of years. This happens until a star passes by, and it’s ripped apart by the monster black hole.
Sciencemag notes that this process triggers a monthslong tidal disruption event (TDE), which will shine even as bright as a supernova.
Studies analyze what’s powering the emissions
It’s been revealed that until recently, experts spotted just a few such TDEs, but now, it seems that there’s a new generation of research that catches more of them just after they start.
“We’re still in the trenches, trying to understand the physical mechanisms powering these emissions,” according to Suvi Gezari of the University of Maryland, College Park.
This month, during the annual meeting of the American Astronomical Society in Honolulu, “Gezari presented an analysis of 39 TDEs: 22 from recent years and 17 detected in the first 18 months of operation of the Zwicky Transient Facility (ZTF), a 1.2-meter survey telescope in California,” according to the website mentioned above.
In a standard TDE photo, the gravity of a black hole is shredding apart an approaching star into strands – just like spaghetti. The monster swallows half of the star’s matter while the rest arcs away.
Some black holes become too big to trigger TDEs
The first TDEs were spotted back in the ’90s. Now, more advanced tech is able to pick up fast-changing events and capture the visible glow in more detail.
Theories are suggesting that black holes can become too massive to trigger TDEs. If a black hole has a mass bigger than 100 million suns, it should swallow a star entirely rather than just tearing it apart.
It’s been revealed that most TDEs are coming from smaller galaxies at the moment and suggests that the limit is a real thing.
