Authors and Co-Authors : - Abstract Type : Oral Abstract Category : Extragalactic astronomy Abstract : High energy emission from blazars is usually assumed to emanate from energetic particles confined in blobs moving along relativistic jets that are pointed at us. Explaining the origin of energetic particles in these blobs is challenging, and the problem is often compounded by observations of short timescale variability. While the concept of blobs is different for different researchers, it is broadly understood that they comprise a mixture of energetic particles and disordered magnetic fields. However, its not clear how this concept meshes with the bulk relativistic fluid flow that is generally thought to comprise the jet. It is not even clear if and how the blob can be represented as a fluid. We will explore these questions in the context of high energy emission from blazars. |
