Analysis Of Gamma-Ray Bursts

Good Essays
Introduction

Our Sun produces enough energy in one second to sustain life on earth for millions of years. However, there is an energy far more powerful than our Sun that makes it pale in comparison. Gamma-ray Bursts (GRBs) are the most energetic type of light in the universe and produce more energy in one second than the sun will produce in its ten-billion year lifetime. These dramatically powerful energetic explosions often originate billions of light-years from Earth yet produce a light so bright that it can be seen through binoculars, making them unequivocally the most powerful burst of energy that we have observed in our universe (Bennett, Donahue, Schneider, & Voit, 2014). This phenomenon has long fascinated scientists and astronomers

The majority of GRBs are now believed to signal the creation of a black hole which creates an explosion of high-energy material (Schwarzschil, 2014). This high-energy material is expelled in jets, mainly composed of electrons, positrons, photons and a small amount of baryons, traveling nearly at the speed-of-light (Taboada, 2011). The energy is released so intensely and instantaneously that in just the first few seconds of the burst, the amount of energy released is equal to what would take the Sun nearly ten-billion years to produce. There is no other process in the universe able to produce this much energy (Bhat, 2011). Additionally, if a GRB was able to distribute itself in all directions equally, such as the way a star does, its luminosity would be that of the combined brightness of a million galaxies such as our Milky Way, albeit briefly (Bennett et al., …show more content…
They arise from the core collapse of massive stars which reside in regions of space experiencing new and active star formation (Savaglio, 2013) and as they are intensely luminous and high in both gamma-ray emission and multi-wavelength afterglow their rate is relative to the star formation rate (Gehrels & Meszaros 2012). However, the core collapse from a supernova explosion from the death of a star that results in the formation of a neutron star is not powerful to create or explain LGRBs. Instead, a LGRB can only be explained as arising when an ultra-energetic supernova becomes a hypernova and creates a black hole that consumes matter so immediately that it releases a substantial amount of energy of the matter which is not consumed (Bennett et al., 2014). The fundamental physics of this collapse of a star and was first proposed and developed by University of California physicist Dr. Stanford Woosley and his Collapsar Model remains the leading explanation for LGRBs today (Taboada,

    The spark of the collapse could have been caused by a galaxy collision, or the shockwave of a neighboring supernova. This collapse causes the cloud to break into fragments. These fragments start to grow as more and more molecules start to attach creating a protostar. The new star starts to increase in temperature, because of the switch from gravitational energy to kinetic energy. The start hasn 't yet gone through nuclear fusion making the star weak and unstable.…

    Also the universe was considered infinite at one point in time but the Big Bang proved that the universe had to have a history and a beginning. (2)According to Chris LaRocco and Blair Rothstein article 15 billion years ago there was an explosion called the Big Bang that created the universe. This explosion contained all the matter and energy of space. Unlike other explosion like a bomb that throw fragments outwards the Big Bang filled in the space with particles of the embryonic universe. Before the Big Bang galaxies were clustered together but the explosion created space and foundation for the universe.…

    The Chicxulub Impact

    The huge pressure forces caused by the air resistance as the asteroid comes through the atmosphere at very fast speeds, causes the asteroid to explode. (10) But with the Chicxulub impactor, the energy, air friction and speed in the impact would have vaporized the asteroid after it hit Earth, along with a large amount of the Earth's crust. This happened because the asteroid was much larger in diameter than most objects that collide with Earth. The impact caused a crater 185 kilometres across to be left on the Earth’s surface and all the left over rock to be thrown into the…

    Astronomy in Yosemite The Sun The sun is a star located at the center of the universe, and without it, there would be no life on Earth. It is the most important source of energy for humans as it provides us light, heat, and more. It can reach surface temperatures of about 5,276 degrees Celsius, and 10,340 degrees Fahrenheit. The composition of the Sun changes slowly as hydrogen is converted into helium in its core; however, it is currently made up of around 70% hydrogen, 28% helium, and less than 2% of other metals. From satellite images of the sun in space, it appears to be a great, red, fiery ball of energy.…

    The Atomic Model

    Scientists believe that stars are made of mostly gas, and this gas is made up of many atoms. In the star, the atoms in the gas bang into each other and give off different light depending on the type of atoms. This light from stars enables scientists to figure out the type and amount of atoms they are made of. Knowing the composition of the stars, we can guess how they were formed. Therefore we can see that stars are just atoms (hydrogen) hitting each other producing light.…

    Daniel went to check the telescopes. There are several reasons that why the astronomers and the scientist chose the far side of moon to place radio telescopes. It is predicted that on the far side of the moon, there will be extremely high concentration of helium-3 because the solar wind, the stream continuously flows come from the Sun with the speed of 400 km/s, containing lots of plasma, electrons, protons and charged particles, was stopped by the Earth’ magnetic shield [14]. Therefore, it naturally forms a perfect surrounding…

    Well, heat, a type of energy, is produced through nuclear fusion. Throughout a star’s life, nuclear fusion is what produces heat to prevent itself from collapsing. However, this process of nuclear fusion ends at some point and the force of gravity overpowers the force from nuclear fusion, causing the star to collapse (“Fusion”). Nuclear fusion is when two atom’s nucleus is combined to make a new atom. However, this process take extreme amount of energy since the nucleuses will always try to push each other away since they both have a positive charge.…

    When the universe was still forming, the universe led to planets collapsing, asteroids running into planets, and galaxies colliding. What if galaxies collided? Last but not least we have, why's if two galaxies were moving towards each other, would they explode? It is scientifically proven that according to the new study, that larger galaxies consume smaller galaxies. But we don't know that for a fact yet.…
