Relativistic inverse Compton scattering of photons from the early universe
Siddharth Malu, Abhirup Datta, Sergio Colafrancesco +4
Electrons at relativistic speeds, diffusing in magnetic fields, cause copious emission at radio frequencies in both clusters of galaxies and radio galaxies, through the non-thermal…
Non-thermal emission and dynamical state of massive galaxy clusters from CLASH sample
M. Pandey-Pommier, J. Richard, F. Combes +5
Massive galaxy clusters are the most violent large scale structures undergoing merger events in the Universe. Based upon their morphological properties in X-rays, they are classifi…
Explosive and radio-selected Transients: Transient Astronomy with SKA and its Precursors
Poonam Chandra, G. C. Anupama, K. G. Arun +7
With the high sensitivity and wide-field coverage of the Square Kilometre Array (SKA), large samples of explosive transients are expected to be discovered. Radio wavelengths, espec…
Curious case of gravitational lensing by binary black holes: a tale of two photon spheres, new relativistic images and caustics
Mandar Patil, Priti Mishra, D. Narasimha
Binary black holes have been in limelight off late due to the detection of gravitational waves from coalescing compact binaries in the events GW150914 and GW151226. In this paper w…
Gravitational Lensing by Self-Dual Black Holes in Loop Quantum Gravity
Satyabrata Sahu, Kinjalk Lochan, D. Narasimha
We study gravitational lensing by a recently proposed black hole solution in Loop Quantum Gravity. We highlight the fact that the quantum gravity corrections to the Schwarzschild m…
Time Delay between Relativistic Images as a probe of Cosmic Censorship
Satyabrata Sahu, Mandar Patil, D. Narasimha +1
We study the time delay between successive relativistic images in gravitational lensing as a possible discriminator between various collapse end states and hence as a probe of cosm…
