Joint User and Beam Selection in Millimeter Wave Networks
Santosh Kumar Singh, Satyabrata Sahu, Ayushi Thawait +2
We study the problem of selecting a user equipment (UE) and a beam for each access point (AP) for concurrent transmissions in a millimeter wave (mmWave) network, such that the sum…
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…
Classicalization of inflationary perturbations by collapse models in the light of BICEP2
Suratna Das, Satyabrata Sahu, Shreya Banerjee +1
Inflationary and hence quantum origin of primordial perturbations is on a firmer ground than ever post the BICEP2 observations of primordial gravitational waves. One crucial ingred…
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…
Quantum to Classical Transition of Inflationary Perturbations - Continuous Spontaneous Localization as a Possible Mechanism -
Suratna Das, Kinjalk Lochan, Satyabrata Sahu +1
The inflationary paradigm provides a mechanism to generate the primordial perturbations needed to explain the observed large scale structures in the universe. Inflation traces back…
Can strong gravitational lensing distinguish naked singularities from black holes?
Satyabrata Sahu, Mandar Patil, D. Narasimha +1
In this paper we study gravitational lensing in the strong field limit from the perspective of cosmic censorship, to investigate whether or not naked singularities, if at all they…
