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…
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…
