Variable Chaplygin Gas: Constraints from Supernovae, GRB and Gravitational Wave Merger Events
Ashley Chraya, Yuvraj Muralichandran, Geetanjali Sethi
We investigate the cosmological constraints on the Variable Chaplygin gas model from the latest observational data: SCP Union 2.1 compilation dataset of Type Ia supernovae (SNe Ia)…
Constraints on the Transition Redshift using Hubble Phase Space Portrait
Darshan Kumar, Deepak Jain, Shobhit Mahajan +2
One of the most significant discoveries in modern cosmology is that the universe is currently in a phase of accelerated expansion after a switch from a decelerated expansion. The r…
A non-parametric test of variability of Type Ia supernovae luminosity and CDDR
Darshan Kumar, Akshay Rana, Deepak Jain +3
The first observational evidence for cosmic acceleration appeared from Type Ia supernovae (SNe Type Ia) Hubble diagram from two different groups. However, the empirical treatment o…
Strong lensing systems and galaxy cluster observations as probe to the cosmic distance duality relation
R. F. L. Holanda, F. S. Lima, Akshay Rana +1
{In this paper, we use large scale structure observations to test the redshift dependence of cosmic distance duality relation (CDDR), }, with $D…
Chiral plasma instability and primordial Gravitational wave
Sampurn Anand, Jitesh R. Bhatt, Arun Kumar Pandey
It is known that cosmic magnetic field, if present, can generate anisotropic stress in the plasma and hence, can act as a source of gravitational waves. These cosmic magnetic field…
Patterns of Genuine Multipartite Entanglement in Frustrated Quantum Spin Systems
Lavisha Jindal, Ameya Deepak Rane, Himadri Shekhar Dhar +2
We investigate the behavior of genuine multipartite entanglement of paradigmatic frustrated quantum spin systems. We consider six different spin models, whose frustration ranges fr…
Quantitative probing of quantum-classical transition for the arrival time distribution
Dipankar Home, Alok Kumar Pan, Arka Banerjee
The classical limit problem of quantum mechanics is revisited on the basis of a scheme that enables a quantitative study of the way the quantum-classical agreement emerges while go…
Dust sputtering by Reverse Shocks in Supernova Remnants
Biman B. nath, Tanmoy Laskar, J. Michael Shull
We consider sputtering of dust grains, believed to be formed in cooling supernovae ejecta, under the influence of reverse shocks. In the regime of self-similar evolution of reverse…
Direction Dependent Non-gaussianity in High-z Supernova Data
Shashikant Gupta, Tarun Deep Saini, Tanmoy Laskar
The most detailed constraints on the accelerating expansion of the universe and details of nature of dark energy are derived from the high redshift supernova data, assuming that th…
On finite groups whose every proper normal subgroup is a union of a given number of conjugacy classes
Ali Reza Ashrafi, Geetha Venkataraman
Let be a finite group and be a normal subgroup of . We denote by the number of -conjugacy classes of and is called -decomposable, if . S…
Radio observations of the circumnuclear ring in NGC6951
D. J. Saikia, B. Phookun, A. Pedlar +1
We present sensitive, high-resolution radio observations of the circumnuclear region of the barred spiral galaxy NGC6951. These observations reveal a ring of radio emission with ma…
