Sahyadri: A simulation suite for the cosmology dependence of the Cosmic Web
Saee Dhawalikar, Shadab Alam, Aseem Paranjape +1
The paper presents Sahyadri, a high‑resolution cosmological N‑body simulation suite that varies key cosmological parameters to enable precise studies of the low‑redshift Universe a…
Learning Cosmology from Nearest Neighbour Statistics
Atrideb Chatterjee, Arka Banerjee, Francisco Villaescusa-Navarro +1
Extracting cosmological parameters from galaxy/halo catalogues with sub-percent level accuracy is an important aspect of modern cosmology, especially in view of ongoing and upcomin…
Nearest Neighbour-Based Statistics for 21cm-Galaxy Cross-Correlations in the Epoch of Reionization
Anirban Chakraborty, Kwanit Gangopadhyay, Arka Banerjee +1
21cm radiation from neutral hydrogen serves as a direct probe of the Epoch of Reionization. However, both its detection and physical interpretation are severely hindered by contami…
Geometric Interpretations of the -Nearest Neighbour Distributions
Kwanit Gangopadhyay, Arka Banerjee, Tom Abel
The -Nearest Neighbour Cumulative Distribution Functions are measures of clustering for discrete datasets that are fast and efficient to compute. They are significantly more inf…
Boosting HI-Galaxy Cross-Clustering Signal through Higher-Order Cross-Correlations
Eishica Chand, Arka Banerjee, Simon Foreman +1
After reionization, neutral hydrogen (HI) traces the large-scale structure (LSS) of the Universe, enabling HI intensity mapping (IM) to capture the LSS in 3D and constrain key cosm…
Exploring Faraday rotation signatures and population bounds for primordial magnetic black holes
Arka Banerjee, Lalit Singh Bhandari, Ashwat Jain +1
Primordial black holes bearing magnetic charges may bypass the constraints imposed by Hawking radiation, thereby enabling reasonable present-day populations, even for masses below…
