John(pondicherry university) and Surajit Paul(Department Of Physics SP Pune University) Abstract Type : Poster Abstract Category : General Relativity and Cosmology Abstract : Fermi I and Fermi II are the most significant particle acceleration methods working in astrophysical objects. Accelerated electrons that emits radio synchrotron emissions in galaxy clusters are also supposed to be accelerated by either of these mechanisms, but still remained highly debated. In this work, we will try to understand how they compete to each other in case of radio halo and relic emission observed in the clusters. We will discuss how the spectral index of radio emission differ from FERMI I and FERMI II and will find a possible solution to problem of non detection of radio halos in clusters having Mpc sized symmetric relics. |
