Testing CCC+TL Cosmology with Observed BAO Features
Rajendra P. Gupta
The primary purpose of this paper is to see how well a recently proposed new model fits (a) the position of the baryon acoustic oscillations (BAO) features observed in the large-sc…
Constraining Co-Varying Coupling Constants from Globular Cluster Age
Rajendra P. Gupta
Equations governing the evolution of a star involve multiple coupling constants. Thus, the time it spends as a main-sequence star can be expected to depend on whether or not such c…
Constraining Coupling Constants' Variation with Supernovae, Quasars, and GRBs
Rajendra P. Gupta
Dirac, in 1937 proposed the variation of coupling constants derived from his large number hypothesis. Efforts have continued since then to constrain their variation by various meth…
Effect of evolutionary physical constants on type-1a supernova luminosity
Rajendra P. Gupta
Type 1a supernovae, SNeIa, are used as standard candles in cosmology for determining the distances of the galaxies harboring them. We show that the luminosity of an SNIa depends on…
