Constraining the Hubble parameter with the 21 cm brightness temperature signal in a universe with inhomogeneities
Subhadeep Mukherjee, Shashank Shekhar Pandey, A. S. Majumdar
We consider the 21\,cm brightness temperature as a probe of the Hubble tension in the framework of an inhomogeneous cosmological model. Employing Buchert's averaging formalism to s…
Analyzing the 21-cm signal brightness temperature in the Universe with inhomogeneities
Shashank Shekhar Pandey, Ashadul Halder, A. S. Majumdar
We explore the 21-cm signal in our Universe containing inhomogeneous matter distribution at considerably large scales. Employing Buchert's averaging procedure in the context of a m…
Future deceleration due to backreaction in a Universe with multiple inhomogeneous domains
Ashadul Halder, Shashank Shekhar Pandey, A. S. Majumdar
We formulate a model of spacetime with inhomogeneous matter distribution in multiple domains. In the context of the backreaction framework using Buchert's averaging procedure, we e…
Enhanced power of gravitational waves and rapid coalescence of black hole binaries through dark energy accretion
Arnab Sarkar, Amna Ali, K. Rajesh Nayak +1
We consider the accretion of dark energy by constituent black holes in binary formations during the present epoch of the Universe. In the context of an observationally consistent d…
Global 21-cm brightness temperature in viscous dark energy models
Ashadul Halder, Shashank Shekhar Pandey, A. S. Majumdar
We investigate the global 21-cm brightness temperature in the context of viscous dark energy (VDE) models. The bulk viscosity of dark energy perturbs the Hubble evolution of the Un…
Effect of inhomogeneities on the propagation of gravitational waves from binaries of compact objects
Shashank S. Pandey, Arnab Sarkar, Amna Ali +1
We consider the propagation of gravitational waves in the late time Universe with the presence of structure. Before detection, gravitational waves emitted from distant sources have…
Stochastic gravitational wave background from accreting primordial black hole binaries during early inspiral stage
Arnab Sarkar, K. Rajesh Nayak, A. S. Majumdar
We investigate the stochastic gravitational wave background produced by primordial black hole binaries during their early inspiral stage while accreting high-density radiation surr…
