A robust prediction from a minimal model of COVID-19 -- Can we avoid the third wave?
Sourav Chowdhury, Suparna Roychowdhury, Indranath Chaudhuri
COVID-19 pandemic is one of the major disasters that humanity has ever faced. In this paper, we try to model the effect of vaccination in controlling the pandemic, particularly in…
Density perturbation and cosmological evolution in the presence of magnetic field in gravity models
Samarjit Chakraborty, Sarbari Guha
In this paper, we have investigated the density perturbations and cosmological evolution in the FLRW universe in presence of a cosmic magnetic field, which may be assumed to mimic…
Thin accretion disks around traversable wormholes
Farook Rahaman, Tuhina Manna, Rajibul Shaikh +3
In this paper, we aim to investigate various physical properties and characteristics of radiation emerging from the surface of accretion disks, in a rotating traversable axially sy…
Variation of Gini and Kolkata Indices with Saving Propensity in the Kinetic Exchange Model of Wealth Distribution: An Analytical Study
Bijin Joseph, Bikas K. Chakrabarti
We study analytically the change in the wealth () distribution against saving propensity in a closed economy, using the Kinetic theory. We estimate the Gini () and…
Detection of nearly periodic spin period reversals in Vela X-1 on long time-scales: inkling of solar-like cycle in the donor star?
Amar Deo Chandra, Jayashree Roy, P. C. Agrawal +1
We explore the long-term evolution of the spin period of the High Mass X-ray Binary (HMXB) pulsar Vela X-1 over a period of 46 yr. Our analysis indicates nearly periodic variations…
Evidence for profile changes in PSR J1713+0747 using the uGMRT
Jaikhomba Singha, Mayuresh P Surnis, Bhal Chandra Joshi +29
PSR J1713+0747 is one of the most precisely timed pulsars in the international pulsar timing array experiment. This pulsar showed an abrupt profile shape change between April 16, 2…
