A new study done by scientists from Dartmouth deals with supermassive black holes and their stages of life. These spatial singularities with immense gravity are thought to be the same type, but apparently, it's not.

Active Galactic Nuclei in the Cosmos

Another term for a black hole is active galactic nuclei (AGNs). To redefine a unified AGN model, which says all the cosmic bodies are all the same, reported SciTech Daily.

Based on a July 15 report in The Astrophysical Journal, they have proposed answers to the exotic gravitational anomalies and how they evolve and develop.

Lead author Tonima Tasnim Ananna says the characteristics of black holes that are substantially hidden are very different from those of AGNs that are not as strongly hidden, noted Science Daily.

Enormous galaxies like the Milky Way are considered to have large solar mass black holes at their centers. Gas, dust, and stars with more mass than tiny galaxies are sucked in by it.

Astronomers are interested in the light given off by the active AGNs, similar to a large solar mass black hole in the accretion stage or rapid growth. These photon emissions were traced back to an AGN in the late 1980s.

The active galactic nuclei have an undefined torus with gas and dust swirling. Differing amounts of light were based on the angle at which it was seen and the torus.

Supermassive Black Holes 

If the unified AGN theory is the dominant explanation, supermassive mass black holes seen in the torus center will look faint. If seen from top to bottom, it looks bright. Past studies were based on less clear objects in space.

Black holes will consume matter in space, but the accretion rates will differ. It is concluded that accretion depends on the mass of black holes, with variations on how obscured the black hole is by the rotation ring of gas and dust.

Ryan Hickox is one of the study's co-authors; he says that a black hole torus isn't the same. A correlation between the structure and how fast it grows.

It consumes more matter and the accretion disc around an AGN, which explains the difference between these bodies. It looks clearer and uncovered if it is more active, which emits more gas and dust. A less active AGN is denser and looks dimmer. Differences in the variations of the cosmic bodies are more than the torus viewpoint.

A Decade of Study on Black Holes

The analysis of AGN detected by the Swift-BAT, a high-energy NASA X-ray telescope, came from this telescope. It looks into the cosmos to look at all kinds of spatial anomalies. All the data came from an international scientific collaboration, BAT AGN Spectroscopic Survey (BASS).

Ananna said they never had such a large sample of X-ray detected obscured local AGN before. It is a big win for high-energy X-ray telescopes.

The paper says a black hole's mass and how fast it consumes matter suggested clues when supermassive black holes got bigger, giving a clue to their origin in the universe. This new study about greater mass blackholes or active galactic nuclei gives a clearer picture of how they evolve in the cosmos.
