Is there an early Universe solution to Hubble tension?
Chethan Krishnan, Eoin Ó Colgáin, Ruchika +3
We consider a low redshift cosmological dataset comprising megamasers, cosmic chronometers, type Ia SNe and BAO, which we bin according to their redshift. For each bin, w…
Cosmology With Low-Redshift Observations: No Signal For New Physics
Koushik Dutta, Anirban Roy, Ruchika +2
We analyse various low-redshift cosmological data from Type-Ia Supernova, Baryon Acoustic Oscillations, Time-Delay measurements using Strong-Lensing, measurements using Cosm…
Beyond CDM with Low and High Redshift Data: Implications for Dark Energy
Koushik Dutta, Ruchika, Anirban Roy +2
Assuming that the Universe at higher redshifts (z \sim 4 and beyond) is consistent with LCDM model as constrained by the Planck measurements, we reanalyze the low redshift cosmolog…
The Price of Shifting the Hubble Constant
Jarah Evslin, Anjan A Sen, Ruchika
An anisotropic measurement of the baryon acoustic oscillation (BAO) feature fixes the product of the Hubble constant and the acoustic scale . Therefore, regardless of the…
Bayesian Evidences for Dark Energy models in light of current obsevational data
Anto. I. Lonappan, Sumit Kumar, Ruchika +2
We do a comprehensive study of the Bayesian evidences for a large number of dark energy models using a combination of latest cosmological data from SNIa, CMB, BAO, Strong lensing t…
Is it time to go beyond CDM universe?
Anto I. Lonappan, Ruchika, Anjan A Sen
Concordance CDM universe is the simplest model that is consistent with a large variety of cosmological observations till date. But few recent observations indicate inconsistenci…
