Gamma ray bursts (GRB) are the most energetic phenomena in the universe which are associated with the creation or merging of neutron stars or black holes. The results are explained with the theory available till the date. gamma ray bursts mainly in their afterglow periods. So evident effects are found on the total electron content of the earths ionosphere due these remote celestial events i.e.
The maximum diurnal TEC increases by 5-8 TECU and 1-3 TECU for GRB 110918A and GRB 190114C respectively at different stations in compare to the day of events. In the following day due to the afterglow emission isotropic influences are observed for both the GRB bursts at almost all the stations in both the hemisphere. Just after the time of spectroscopic detection of GRB in late night, due to prompt emission though no remarkable effect was observed in case of 1st GRB but remarkable unusual variations (maximum 2 TECU) are observed in case of 2nd GRB in the diurnal TEC curves mainly at high latitude stations in both hemispheres. The influence of these bursts on the total electron content (TEC) of the earths ionosphere is studied using the data provided by the international GPS service network (IGS) for the stations at high, middle and low latitudes in both hemispheres in Asian-Australian region. Influence of The Remote Celestial Event Like Gamma Ray Bursts GRB 190114C and GRB 110918A on The Total Electron Content of The Earths Ionosphere: A Case StudyĢDepartment of Physics, Ishwarchandra Vidyasagar College, Belonia-799155,Tripura, India.ġDepartment of Physics, Tripura University Suryamaninagar-799022, Tripura, IndiaĪbstract: During a supernova or super luminous supernova, an intense gamma radiation is released, known as Gamma Ray Burst (GRB).Two bright gamma-ray bursts (GRB 110918A and GRB 190114C) were detected on the earth in the year 20.
