Cosmic researchers uncover the most vigorous cosmic blasts ever recorded
In a groundbreaking discovery, a team of international researchers has identified a new class of cosmic explosions known as Extreme Nuclear Transients (ENTs). These extraordinary events occur when supermassive black holes violently consume massive stars, providing valuable insights into black hole growth during the cosmic noon era.
The researchers' findings were published in the journal Science Advances, detailing the unique characteristics of ENTs that set them apart from typical tidal disruption events (TDEs).
ENTs are significantly more energetic and long-lasting than TDEs. They are nearly 10 times brighter than their TDE counterparts, emitting energy up to 25 times greater than the most powerful supernovae. While TDEs have a shorter duration, ENTs remain luminous for years, far surpassing the energy output of even the brightest known supernova explosions.
The brightness and energy output of ENTs are so immense that they far surpass even the brightest known supernova explosions. In fact, the strongest documented ENT, Gaia18cdj, released 25 times more energy than the most energetic supernovae.
The detection of ENTs has been aided by surveys such as the European Space Agency's Gaia mission, which identified unusually long-lived and bright flares from galactic centers. The discovery of ENTs took place almost by accident during a search for enduring flares from the center of galaxies.
ENTs offer unique insights into the dynamics of supermassive black holes and galaxy evolution due to their extreme nature and rarity, possibly millions of times rarer than supernovae. By observing ENTs, astronomers gain insights into black hole growth processes responsible for growing the largest black holes in the universe.
The study of ENTs could potentially lead to a better understanding of theories about black holes leading to white holes, the universe existing in a black hole, and supermassive black holes replacing particle colliders. The discovery of ENTs represents some of the most powerful cosmic explosions observed to date.
In Hawaii, astronomers have discovered a new ENT event in an astronomical survey called the Zwicky Transient Facility (ZTF) in 2020. Two ENT events were found in data from the European Space Agency's Gaia mission in 2016 and 2018.
The recent study sheds light on the mysteries of black holes, contributing to a host of ongoing research. As the field of astrophysics continues to evolve, the discovery of ENTs promises to open new avenues for exploration and understanding the universe's most powerful phenomena.
