Padé semi-cosmographic reconstruction of residual dark energy in decaying dark matter cosmology: DESI DR2 BAO constraints and mock 21 cm forecasts
Mohit Yadav, Pankaj Chavan, Tapomoy Guha Sarkar
Pure cosmographic reconstructions provide a model-agnostic approach towards constraining cosmic evolution.We develop a hybrid phenomenological semi-cosmographic framework that adop…
Disentangling the growth rate of perturbations from the HI bias using only clustering data from galaxy surveys
Pankaj Chavan, Tapomoy Guha Sarkar, Anjan A Sen
This work serves two-fold purpose. Firstly, we provide an alternative to the traditional method of determining the growth rate of density perturbations . In usual practice, $…
The dynamics of background evolution and structure formation in phase space: a semi-cosmographic reconstruction
Pankaj Chavan, Tapomoy Guha Sarkar, Anjan A Sen
The Baryon Acoustic Oscillation (BAO) feature, imprinted in the transverse and radial clustering of dark matter tracers, enables the simultaneous measurement of the angular diamete…
A semi-cosmographic approach to study cosmological evolution in phase space
Pankaj Chavan, Tapomoy Guha Sarkar, Chandrachud B. V. Dash +1
The signature of Baryon Acoustic Oscillation in the clustering of dark-matter tracers allows us to measure independently. Treating these as conjugate variables, we…
