Numerical analysis of electron density and response time delay during solar flares in mid-latitudinal lower ionosphere
Sayak Chakraborty, Tamal Basak
Impacts of solar flare vary at different parts of the lower ionosphere depending on its proximity to the direct exposure of incoming solar radiation. The quantitative analysis of t…
RAD@home discovery of a bow-and-arrow radio galaxy tracing a ~560 kpc bow-shock structure in a multi-halo environment
Ananda Hota, Pratik Dabhade, Shubhrangshu Ghosh +9
We report the RAD@home citizen science discovery of a unique bow-and-arrow-shaped radio galaxy (BAARG; RAD J104501.6+352852, z = 0.159) identified in LoTSS DR2. The source exhibits…
Cosmological Dynamics of Exponential Quintessence Constrained by BAO, Cosmic Chronometers, and DES-SN5YR/Pantheon+ Data
Sanjeeda Sultana, Surajit Chattopadhyay
We perform a comprehensive observational test of a canonical quintessence model driven by an exponential potential, motivated by its emergence in higher-dimensional theories, strin…
Quasi-elastic scattering for the nuclear ground state structure: An intriguing case of Si
Y. K. Gupta, B. Maheshwari, G. K. Prajapati +17
Quasi-elastic (QEL) scattering measurements have been performed using the Si projectiles off the Zr target at energies around the Coulomb barrier. Coupled-channel…
Non-Singular Bouncing cosmology from Phantom Scalar-Gauss-Bonnet Coupling: Reconstruction with Observational Insights
Khandro K. Chokyi, Surajit Chattopadhyay
We examine non-singular bounce cosmology within the framework of a phantom scalar field coupled to the Gauss-Bonnet term in both non-viscous and bulk-viscous cases. Using the scale…
A Combined Barrow Entropy and QCD Ghost Mechanism for Late-Time Cosmic Acceleration
Aziza Altaibayeva, Ulbossyn Ualikhanova, Zhanar Umurzakhova +1
We investigate a unified dark-energy scenario based on the combined effects of Barrow entropy corrections and the QCD ghost mechanism, referred to as the BH--QCDGDE model. The dark…
