Interacting tachyon with varying mass dark matter
Goutam Mandal, Sudip Mishra, Abdulla Al Mamon +1
This paper presents an investigation of cosmological dynamics of tachyon fluid coupled to varyingmass dark matter particles in the background of spatially flat FLRW universe. The m…
Interacting Holographic dark energy with matter creation: A dynamical system analysis
Goutam Mandal, Santosh Biswas, Sujay Kr. Biswas
An interacting Holographic dark energy (HDE) with different infra-red (IR) cutoffs (Hubble horizon and future event horizon) is investigated in the background dynamics of flat Frie…
Dynamical systems analysis of a cosmological model with interacting Umami Chaplygin fluid in adiabatic particle creation mechanism: Some bouncing features
Goutam Mandal, Sujay Kr. Biswas
The present work aims to investigate an interacting Umami Chaplygin gas in the background dynamics of a spatially flat Friedmann-Lemaitre-Robertson-Walker (FLRW) universe when adia…
Phase space analysis and cosmography of a two-fluid cosmological model
Goutam Mandal, Sujay Kr. Biswas
In the framework of spatially flat Friedmann-Lemaitre-Robertson-Walker (FLRW) space-time, we investigate a two-fluid cosmological model where a tachyon scalar field with self-inter…
