Spinning compact object and chaos in galactic centers
Ushasee Paria, Uditi Nag, Yeasin Ali +1
Galactic centres are highly dynamic regions dominated by a supermassive black hole (BH) surrounded by nuclear star clusters (NSC), molecular gas, and asymmetric matter distribution…
Exploring Chaotic Motion of a Particle in the Centre of a Galaxy with a Prolate Halo
Uditi Nag, Yeasin Ali, Suparna Roychowdhury
The majority of galaxies are known to have supermassive black holes (SMBHs) at their core, which have a tremendous gravitational pull on the objects around them. When embedded with…
Universal features of epidemic and vaccine models
Sourav Chowdhury, Indrani Bose, Suparna Roychowdhury +1
In this paper, we study a stochastic susceptible-infected-susceptible (SIS) epidemic model that includes an additional immigration process. In the presence of multiplicative noise,…
Chaotic Dynamics in a Galactic Multipolar Halo with a Compact Primary
Yeasin Ali, Suparna Roychowdhury
Observational evidence strongly supports the existence of a Super Massive Black Hole (SMBH) at the Galactic center, surrounded by dense stellar clusters. Modeling galactic centers…
Studying ECG signals using nonlinear oscillators and Genetic Algorithm
Sourav Chowdhury, Apratim Ghosal, Suparna Roychowhury +1
Cardiovascular diseases are the leading cause of death and disability in the world and thus their detection is extremely important as early as possible so that it can be prognosed…
