Parameterizing the Standing Accretion Shock Instability for Inference with Galactic Supernova Neutrino Signals at IceCube
Dwaipayan Mukherjee, Mohamed Rameez, Basudeb Dasgupta
Simulations of core-collapse supernovae have revealed an epoch of hydrodynamic instability in which the matter of the collapsing star undergoes quasi-periodic oscillations, known a…
Clustering properties of the CatWISE2020 quasar catalogue and their impact on the cosmic dipole anomaly
Sebastian von Hausegger, Nathan Secrest, Harry Desmond +3
The cosmic dipole anomaly -- the observation of a significant mismatch between the dipole observed in the matter distribution and that expected given the kinematic interpretation o…
Anisotropy in Pantheon+ supernovae
Animesh Sah, Mohamed Rameez, Subir Sarkar +1
We employ Maximum Likelihood Estimators to examine the Pantheon+ catalogue of Type Ia supernovae for large scale anisotropies in the expansion rate of the Universe. The analyses ar…
Forty years of the Ellis-Baldwin test
Nathan Secrest, Sebastian von Hausegger, Mohamed Rameez +2
Modern cosmology is built on the assumption that the Universe is homogeneous and isotropic on large scales - but this is challenged by results of the Ellis-Baldwin test that show a…
Anisotropy in the cosmic acceleration inferred from supernovae
Mohamed Rameez
Under the assumption that they are standard(isable) candles, the lightcurves of Type Ia supernovae have been analyzed in the framework of the standard Friedmann-Lemaître-Robertson…
