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…
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…
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…
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…
Merian: A Wide-Field Imaging Survey of Dwarf Galaxies at z~0.06-0.10
Shany Danieli, Erin Kado-Fong, Song Huang +32
We present the Merian Survey, an optical imaging survey optimized for studying the physical properties of bright star-forming dwarf galaxies. Merian is carried out with two medium-…
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…
High-energy Neutrino Source Cross-correlations with Nearest-neighbor Distributions
Zhuoyang Zhou, Jessi Cisewski-Kehe, Ke Fang +1
The astrophysical origins of the majority of the IceCube neutrinos remain unknown. Effectively characterizing the spatial distribution of the neutrino samples and associating the e…
Spatial clustering of gravitational wave sources with -nearest neighbour distributions
Kaustubh Rajesh Gupta, Arka Banerjee
We present a framework to quantify the clustering of gravitational wave (GW) transient sources and measure their spatial cross-correlation with the large-scale structure (LSS) of t…
Small-scale signatures of primordial non-Gaussianity in k-Nearest Neighbour cumulative distribution functions
William R. Coulton, Tom Abel, Arka Banerjee
Searches for primordial non-Gaussianity in cosmological perturbations are a key means of revealing novel primordial physics. However, robustly extracting signatures of primordial n…
