Photospheric Lorentz force changes in eruptive and confined solar flares
Samriddhi Sankar Maity, Ranadeep Sarkar, Piyali Chatterjee +1
Solar flares are known to leave imprints on the magnetic field at the photosphere, often manifested as an abrupt and permanent change in the downward-directed Lorentz force in loca…
Resolution of the incongruency of dipole asymmetries within various large radio surveys -- implications for the Cosmological Principle
Ashok K. Singal
We investigate dipole asymmetries in four large radio surveys, each spanning more than 80\% of the sky. Two of them, the Very Large Array Sky Survey (VLASS) and the Rapid ASKAP Con…

Applications of the proxy- model of Bonatsos and collaborators to nuclei in A=60-90 region introduces proxy- symmetry. Shell model spaces with single particle (sp) or…
Warp and flare of the old Galactic disc as traced by the red clump stars
Namita Uppal, Shashikiran Ganesh, Mathias Schultheis
Our study aims to investigate the outer disc structure of the Milky Way galaxy using the red clump (RC) stars. We analysed the distribution of the largest sample of RC stars to dat…
Unitarity Bound on Dark Matter in Low-temperature Reheating Scenarios
Nicolás Bernal, Partha Konar, Sudipta Show
Model-independent theoretical upper bound on the thermal dark matter (DM) mass can be derived from the maximum inelastic DM cross-section featuring the whole observed DM abundance.…
Study of the fastest classical nova, V1674 Her: Photoionization and Morpho-kinemetic model analysis
Gesesew R. Habtie, Ramkrishna Das, Ruchi Pandey +2
We present the results of the investigation of the nova V1674 Her (2021), recognised as the swiftest classical nova, with days. The distance to the nova is estimate…
Large-scale shell-model study of two-neutrino double-beta decay of Se, Zr, Cd, Sn, Te, Te, Xe, and Nd
Deepak Patel, Praveen C. Srivastava, V. K. B. Kota +1
Large-scale shell-model calculations have been performed for the study of two neutrino double-beta () decay in Se, Zr, Cd, Sn, Te, $^{13…
Soft supersymmetry breaking as the sole origin of neutrino masses and lepton number violation
Anjan S. Joshipura, Ketan M. Patel
We discuss a scenario in which the supergravity induced soft terms, conventionally used for breaking supersymmetry, also lead to non-zero Majorana neutrino masses. The soft terms l…
Quantum corrections and the minimal Yukawa sector of
Ketan M. Patel, Saurabh K. Shukla
It is well-known that the grand unified theory, with the standard model quarks and leptons unified in and and the electroweak Higgs doublet residing in…
