Classification of Fanaroff-Riley Radio Galaxies using Conventional Machine Learning Techniques

2019 International Multidisciplinary Information Technology and Engineering Conference (IMITEC), 2019
Large scale radio astronomy projects such as the Square Kilometre Array (SKA) is expected to produce extremely large data sets (300 PB p/a), which makes purely manual classification no longer a viable option. An automatic method of radio galaxy classification is proposed in this paper that will examine the performance of conventional classification ...

The role of Fanaroff-Riley II radio galaxies in the acceleration of the most energetic cosmic rays

Nuclear Physics B - Proceedings Supplements, 2007
Possible sources of ultra-high energy cosmic rays are the hot-spots of Fanaroff-Riley II radio galaxies. In fact, these regions meet the requirements of size, magnetic field intensity and presence of strong shocks for accelerating particles up to energies that exceed 10 21  eV . On the other hand, the interaction with the photons of the Cosmic

Ultrahigh-energy cosmic rays from Fanaroff Riley class II radio galaxies

AIP Conference Proceedings, 1992
The hot spots of Fanaroff Riley class II radio galaxies are argued to be the sources of the ultrahigh energy component in cosmic rays. We present calculations of cosmic ray transport in an evolving universe, taking the losses against the microwave background properly into account.

Dust in BL Lac objects and Fanaroff-Riley radio galaxies: infrared region

Astrophysics and Space Science, 2015
Here 28 BL Lac objects, 18 FR I type radio galaxies, 4 FR I/II type radio galaxies and 10 FR II type radio galaxies are studied from FIR (far infrared) to optical region (180 μm to 0.44 μm) to understand the nature of infrared emission from these objects and the physical properties of dust in the emitting region.
