Impact of CMB low- EE polarization data on dark energy parameterizations
Shubham Barua, Shantanu Desai
Measurement of the optical depth to reionization () is largely driven by the large-scale EE polarization data of CMB (). Removing the low- EE data p…
Probing cosmic anisotropy with galaxy clusters and supernovae
Shubham Barua, Sujit K. Dalui, Shantanu Desai
Using CDM and Padé-(2,1) cosmography, we study directional variations in the Hubble constant, , using galaxy cluster and Type Ia Supernovae (from Pantheon Plus) by the he…
Cosmological Constraints on Neutrino Masses in a Second-Order CPL Dark Energy Model
Shubham Barua, Shantanu Desai
Recent DESI results indicate a strong preference for dynamical dark energy (DE) when baryon acoustic oscillation (BAO) measurements are combined with supernovae (SNe) and cosmic mi…
On frequentist confidence intervals in a non-Gaussian regime
Shubham Barua, Shantanu Desai, Mauricio Lopez-Hernandez +1
We study frequentist confidence intervals based on graphical profile likelihoods (Wilks' theorem, likelihood integration), and the Feldman-Cousins (FC) prescription, a generalisati…
Testing the cosmic distance duality relation using model-independent approach
Shubham Barua, Sujit K. Dalui, Rikiya Okazaki +1
In this work, we test the cosmic distance duality relation (CDDR) using the arbitrary redshift pivot Padé-(2,1) expansion methodology developed in arXiv:2509.16196. This approach…
Constraints on Dark Energy Models Using Late Universe Probes
Shubham Barua, Shantanu Desai
We use late Universe probes - Type Ia Supernovae from the PantheonPlus compilation, Quasars, and Dark Energy Spectroscopic Instrument (DESI) Data Release 1 (DR1) BAO data - along w…
