On Super-Hyperbolic Wormhole Geometries and their Deformations
Subrat Parida
In this study, we developed a unified geometric and relativistic framework for a new family of traversable wormholes constructed from a super-hyperbolic deformation of the classica…
Spatial Correlations of PAH, UV, H Emission and IMF - PAH Variations in the Star-Forming Complexes of NGC 628
S Amrutha, Dimitra Rigopoulou, Mousumi Das +1
We examine the spatial correlation of emission from polycyclic aromatic hydrocarbons (PAH) (3.3 m, 7.7 m, and 11.3 m) with the far-ultraviolet (FUV), near-ultraviolet (…
Closed-form representations of extended astrophysical thermonuclear functions
Subrat Parida
Reaction rate determination is an essential problem in the theories of cosmological and stellar nucleosynthesis. I investigate the closed-form analytic evaluation of thermonuclear…
Optical observations of the fast nova V1674 Herculis
Neeraj Singh Rawat, L. S. Sonith, U. S. Kamath +3
We present the evolution of optical spectra and lightcurves of the fast nova V1674 Herculis during 150 days past its eruption. Using the post-eruption AAVSO light curve, we have ca…
Subluminous Type IIP SN 2024abfl as a Result of a Significantly Low-energy Fe-core Collapse
Rishabh Singh Teja, D. K. Sahu, G. C. Anupama +7
We present extensive, well-sampled multiwavelength photometric and low-resolution optical spectroscopic observations of the low-luminosity Type IIP supernova SN 2024abfl. SN 2024ab…
Quantum Field Theory in Successive Rindler Spacetimes
Nitesh K. Dubey, Jaswanth Uppalapati, Sanved Kolekar
We study successive Rindler-like transformations in Minkowski spacetime and the corresponding sequence of vacuum states perceived by observers restricted to respective wedges. Exte…
