Fully Characterizing Axially Symmetric Szekeres Models With Three Data Sets
Marie-Noëlle Célérier, Priti Mishra, Tejinder P. Singh
Inhomogeneous exact solutions of General Relativity with zero cosmological constant have been used in the literature to challenge the ΛCDM model. From one patch Lemaître-Tolman-Bon…
An effectual template bank for the detection of gravitational waves from inspiralling compact binaries with generic spins
P. Ajith, N. Fotopoulos, S. Privitera +3
We report the construction of a three-dimensional template bank for the search for gravitational waves from inspiralling binaries consisting of spinning compact objects. The parame…
Noise Kernel for Self-similar Tolman Bondi Metric: Fluctuations on Cauchy Horizon
Seema Satin, Kinjalk Lochan, Sukratu Barve
We attempt to calculate the point separated Noise Kernel for self similar Tolman Bondi metric, using a method similar to that developed by Eftekharzadeh et. al for ultra-static spa…
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…
Statistical analysis of entropy correction from topological defects in Loop Black Holes
Kinjalk Lochan, Cenalo Vaz
In this paper we discuss the entropy of quantum black holes in the LQG formalism when the number of punctures on the horizon is treated as a quantum hair, that is we compute the bl…
Shell-crossings in Gravitational Collapse
Pankaj S. Joshi, Ravindra V. Saraykar
While studying the continual gravitational collapse of a massive matter cloud in general relativity towards examining collapse final states, an important issue is that of whether s…
Modified gravity as a common cause for cosmic acceleration and flat galaxy rotation curves
Priti Mishra, Tejinder P. Singh
Flat galaxy rotation curves and the accelerating Universe both imply the existence of a critical acceleration, which is of the same order of magnitude in both the cases, in spite o…
Hawking radiation from dynamical horizons
Ayan Chatterjee, Bhramar Chatterjee, Amit Ghosh
In completely local settings, we establish that a dynamically evolving black hole horizon can be assigned a Hawking temperature. Moreover, we calculate the Hawking flux and show th…
Tunneling during Quantum Collapse in AdS Spacetime
Cenalo Vaz, Kinjalk Lochan
We extend previous results on the reflection and transmission of self-gravitating dust shells across the apparent horizon during quantum dust collapse to non-marginally-bound dust…
Statistical thermodynamics for a non-commutative special relativity: Emergence of a generalized quantum dynamics
Kinjalk Lochan, Seema Satin, Tejinder P. Singh
There ought to exist a description of quantum field theory which does not depend on an external classical time. To achieve this goal, in a recent paper we have proposed a non-commu…
Ultra-high energy particle collisions in a regular spacetime without blackholes or naked singularities
Mandar Patil, Pankaj S. Joshi
We investigate here the particle acceleration and collisions with extremely large center of mass energies in a perfectly regular spacetime containing neither singularity nor an eve…
Canonical Partition function of Loop Black Holes
Kinjalk Lochan, Cenalo Vaz
We compute the canonical partition for quantum black holes in the approach of Loop Quantum Gravity (LQG). We argue that any quantum theory of gravity in which the horizon area is b…
Recent developments in gravitational collapse and spacetime singularities
Pankaj S. Joshi, Daniele Malafarina
It is now known that when a massive star collapses under the force of its own gravity, the final fate of such a continual gravitational collapse will be either a black hole or a na…
