Unveiling the First Monster Black Hole: Surprise Gamma-Ray Eruption
In a groundbreaking discovery that has left the scientific community in awe, the Event Horizon Telescope (EHT) has captured a surprise gamma-ray eruption from the supermassive black hole M87*. This astonishing event marks the first time such an eruption has been observed since 2010, shedding new light on the mysterious nature of these cosmic giants.
The eruption, which lasted for three days in April and May 2018, emanated from the heart of the galaxy M87, located a staggering 55 million light-years away from Earth. The gamma-ray flare was detected by the 25 ground-based and orbiting telescopes that make up the EHT, providing researchers with a unique opportunity to study the structure surrounding supermassive black holes.
Understanding the Phenomenon
Supermassive black holes are believed to exist at the center of most large galaxies, including our own Milky Way. M87*, however, stands out with its colossal mass equivalent to 5.4 billion suns, compared to the 4.3 million suns that make up Sagittarius A*, the Milky Way’s central supermassive black hole. This difference in mass is a key factor in understanding the behavior of these enigmatic cosmic entities.
Black Holes: Messy Eaters
Contrary to popular belief, supermassive black holes like M87* are not efficient eaters. They are surrounded by vast amounts of matter in the form of an accretion disk and superheated gas known as plasma. This matter is slowly fed to the black hole due to its angular momentum, swirling around it before being channeled to its poles by powerful magnetic fields. The accelerated particles are then ejected as high-energy jets, accompanied by bursts of electromagnetic radiation like the gamma-ray flare observed by the EHT.
Collaborative Discoveries
The multi-band campaign in 2018 involved a collaboration between the EHT and various space-based instruments like Fermi, NuSTAR, Chandra, and Swift. By combining data from these observatories, scientists were able to identify changes in the angle of the jet from M87* and correlated variations in the event horizon of the black hole. These findings offer valuable insights into the mechanisms behind the powerful jets launched by black holes and their connection to event horizons.
The research findings, published in the journal Astronomy & Astrophysics, have opened up new avenues for understanding the fundamental questions of astrophysics that continue to elude scientists. This unprecedented discovery underscores the importance of collaborative efforts in unraveling the mysteries of the cosmos and marks a significant milestone in our quest for knowledge about the universe.
