Isotropy Test with Quasars Using Method of Smoothed Residuals
Akhil Antony, Stephen Appleby, William L Matthewson +1
To assess the significance and scale dependence of anomalous large scale modes in the CatWISE quasar data, we generate smoothed number density fields on the sphere and study their…
A search for super-imposed oscillations to the primordial power spectrum in Planck and SPT-3G 2018 data
Akhil Antony, Fabio Finelli, Dhiraj Kumar Hazra +2
We search for super-imposed oscillations linearly or logarithmically spaced in Fourier wavenumbers in Planck and South Pole Telescope (SPT-3G) 2018 temperature and polarization…
Discordances in cosmology and the violation of slow-roll inflationary dynamics
Akhil Antony, Fabio Finelli, Dhiraj Kumar Hazra +1
We identify examples of single field inflationary trajectories beyond the slow-roll regime which improve the fit to Planck 2018 data compared to baseline CDM model with power la…
One spectrum to cure them all: Signature from early Universe solves major anomalies and tensions in cosmology
Dhiraj Kumar Hazra, Akhil Antony, Arman Shafieloo
Acoustic peaks in the Cosmic Microwave Background (CMB) temperature spectrum as observed by the Planck satellite appear to be smoother than our expectation from the standard model…
Effect of damped oscillations in the inflationary potential
Akhil Antony, Shweta Jain
We investigate the effect of damped oscillations on a nearly flat inflationary potential and the features they produce in the power-spectrum and bi-spectrum. We compare the model w…
