Evolving Cosmic Scenario in Modified Chaplygin Gas with Adiabatic Matter Creation
Subhra Bhattacharya, Shibaji Halder, Subenoy Chakraborty
Modified Chaplygin Gas has been successful in describing the cosmic history of the universe from radiation to CDM in standard cosmology, while particle creation mechanism in non…
The origin of the X-ray, radio and HI structures in the NGC 5903 galaxy group
Ewan O'Sullivan, Konstantinos Kolokythas, Nimisha G. Kantharia +3
The NGC 5903 galaxy group is a nearby (~30 Mpc) system of ~30 members, dominated by the giant ellipticals NGC 5903 and NGC 5898. The group contains two unusual structures, a ~110 k…
The Complete Local Volume Groups Sample - I. Sample Selection and X-ray Properties of the High-Richness Subsample
Ewan O'Sullivan, Trevor J. Ponman, Konstantinos Kolokythas +7
We present the Complete Local-Volume Groups Sample (CLoGS), a statistically complete optically-selected sample of 53 groups within 80 Mpc. Our goal is to combine X-ray, radio and o…
Nonequilibrium phase transition in spin-S Ising ferromagnet driven by Propagating and Standing magnetic field wave
Ajay Halder, Muktish Acharyya
The dynamical response of spin-S (S=1, 3/2, 2, 3) Ising ferromagnet to the plane propagating wave , standing magnetic field wave and uniformly oscillating field with constant frequ…
Towards simulating and quantifying the light-cone EoR 21-cm signal
Rajesh Mondal, Somnath Bharadwaj, Kanan K. Datta
The light-cone (LC) effect causes the Epoch of Reionization (EoR) 21-cm signal to evolve significantly along the line of sight (LoS) direction . In…
Coupling conditions for globally stable and robust synchrony of chaotic systems
Suman Saha, Arindam Mishra, E. Padmanaban +4
We propose a set of general coupling conditions to select a coupling profile (a set of coupling matrices) from the linear flow matrix (LFM) of dynamical systems for realizing globa…
