High energy astronomy is one of the subdivisions in observational astronomy. This method is used to study the astronomical object that emits high energy electromagnetic radiation due to the cosmic explosion.
Regarding this, X-ray observation is one of the effective techniques used in high energy astronomy. Recently NASA’s Chandra Space Observatory captured a mysterious cosmic flare using X-ray observation technique. Researchers say this X-ray source likely comes from some sort of cosmic explosion.
Surprisingly, the image is the deepest Space image ever obtained. Though, scientists are astonished about some distinct features in the cosmic explosion that they never saw before. By the way, The X-ray source was originally discovered in October 2014 by a group of Astronomers from Penn State University.
According to Penn University, the most notable group members are Bin Luo, Niel Brandt, and Franz Bauer. They have gathered data by using the Advanced CCD Imaging Spectrometer on Chandra. The location of the potential cosmic explosion is known as the Chandra Deep Field-South or CDF-S region.
Moreover, the flair source was not detected in X-rays before October 2014. But when some kind of cosmic explosion erupted in that region then it glows 1000 time brighter within few hours. Therefore after a single day, the source had faded completely below the sensitivity of Chandra.
A detailed study from the Hubble and Spitzer Telescopes helps to determine the exact location of the cosmic explosion. They find the event came from a faint, small galaxy about 10.7 billion light-years from Earth. Interestingly, the event produced a thousand times more energy than overall stars in this galaxy.
However, astronomers presume three theories but Two of them explain the X-ray source invoke Gamma-Ray Burst events. GRB is one type of jetted cosmic explosion, triggered by the collapse of a massive star. Besides, the merger of a neutron star with another neutron star or a black hole also results in the similar effect.
In addition, when the jet from the cosmic explosion is pointing towards earth then a burst of gamma-rays detected. However, when the jet is expanding its losses energy and produces weaker, more isotropic radiation at X-ray and other wavelengths. All the related papers are published in Cornell University journal.
The most distinct property of this cosmic explosion in the CDF-S region is luminosity. Even it is different from an x-ray source at elliptical galaxies NGC 5128 and NGC 4636 detected by Jimmy Irwin. Actually, the event is associated with the complete destruction of a neutron star or white dwarf. So it is comparatively 100,000 times more luminous in X-rays. However, it was detected in a younger galaxy and for several hours.
