Universe’s Gammay-ray bursts can leave behind Black holes

The most powerful explosions in the universe is nothing but the Gamma-rays burst, these Gamma-rays burst occurs when certain stars collapse in the universe and release overwhelming blast of energy and the cosmic left over which is considered as a violent outburst of nature.

Studies have suggested that Gamma-rays bursts can leave behind black holes like cosmic gravestones and the remaining may end up as spinning neutron stars. The other studies have also suggested that certain class of brightest and the most powerful Gamma-rays burst only because of black holes. Gamma-rays burst occur when certain massive stars have reached end of their lives and gives fuel for nuclear fusion in their cores without the pressure from the nuclear fusion pushing outward the gravity wins.

Brad Cenko a post-doctoral fellow from the University of California-Berkerly, said that the energy released from these events have too huge power by collapse and to form a neutron star which is known as a Magnetars. Magnetars are nothing but a type of neutron stars, where as a neutron are nothing but an object having protons and electrons in a merged form and that are spinning very quickly with extremely powerful magnetic fields.

Neutron stars if they weigh over a certain limit then gravity would have collapsed the object further into a black hole thus neutron stars are restricted in how massive they can be. Whereas black holes have no upper mass limit so it will incorporate any number of mass needed to power a Gamma-ray burst.

Scientist studied a sampling of Gamma-ray bursts observed by NASA’s Swift Gamma-ray satellite and they have found that 11 Gamma-rays bursts bore similar signatures in the same pattern of the light they emitted and also observed a magnetar was present in it.

But some scientists say magnetars would not be huge enough to produce energy required for a Gamma-ray burst.
