Basis function expansions of the two-point correlation function and reconstruction of the cosmological distance scale
Fatima Abd Alrahman, Farnik Nikakhtar, Marcello Musso +2
The shape of the correlation function of galaxy pairs can be used as a cosmological distance indicator. Most estimators of this shape require that one bin the pair counts, and cons…
Filaments within filaments: unraveling the hierarchy of the cosmic web
Saee Dhawalikar, Aseem Paranjape, Shadab Alam
Cosmic filaments are the most striking feature of the hierarchical cosmic web. Yet, their own sub-structure remains unexplored, unlike the well-known, universal halo/sub-halo hiera…
Evolution of Neutron Star Environment in the Galactic Halo : Implications for Dark Matter Accretion
Payaswinee Arvikar, Aseem Paranjape, Saee Dhawalikar
Neutron stars (NS) are one of the indirect detection probes for dark matter (DM). The presence of DM is known to affect the observable properties of NS. Theoretical calculations fo…
Impact of fiducial cosmology in model-agnostic cosmological inference with the BAO feature
Aseem Paranjape, Ravi K. Sheth
In recent work, we have developed a model-agnostic framework for cosmological inference using the baryon acoustic oscillation (BAO) feature in redshift space. The framework, which…
Zel'dovich smearing approximation of the BAO feature for model-agnostic cosmological inference
Aseem Paranjape, Ravi K. Sheth
A model-agnostic description of the baryon acoustic oscillation (BAO) feature in redshift space requires a number of ingredients. Physically, one must describe the impact of cosmol…
Sahyadri: A simulation suite for the cosmology dependence of the Cosmic Web
Saee Dhawalikar, Shadab Alam, Aseem Paranjape +1
We present Sahyadri, a suite of cosmological -body simulations designed to enable precision studies of the low-redshift Universe with next-generation spectroscopic surveys. Sahy…
