| Abstract | Inverse Compton scattering is the interaction process between photons and ultrarelativistic electrons as a result of this process, the frequency of scattered photons violently increases. This mechanism plays important part in origin of X-ray and gamma-ray emission in astrophysical objects, such as jets of quasars and active galaxies, supernova remnants, pulsars. Generally, in this objects the frequency and energy distributions have a low-power nature due to the acceleration processes of cosmic rays. Usually, the consideration of inverse Compton effect is constrained by assumption that the scattering emission is isotropic [1]. For example, such situation takes place at the scattering on the cosmic microwave background. In present work we analyze the inverse Compton scattering of anisotropic low-power radio emission of quasar on relativistic jet's electrons by the example of the nearest quasar 3C 273. The flux density of quasar emission is $Fa(ω)∞ω^{−α}.$ The relativistic electrons in the nearest to the quasar knot (the region of increased surface brightness in which acceleration processes occur) of kiloparsec jet have low-power energy spectrum $f(Γ)∞Γ^{−γ},$ it follows from data of his optical and radio synchrotron emission. In present task the angle of the jet with line of sight, it is also the angle between initial and scattered photon impulses, is known θ≈30°[2]. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
