High-Redshift Signatures from the Cosmic Dawn and the Epoch of Reionization
Rennan Barkana, Oliver Basquette, Ankita Bera +22
In this chapter, we provide a comprehensive overview of the astrophysical and cosmological processes that shape the 21-cm signal during Cosmic Dawn and the Epoch of Reionization. W…
Understanding the non-Gaussian nature of Galactic foreground emissions towards small scales
Fazlu Rahman, Pravabati Chingangbam, Kevin Huffenberger +4
We present a unified, multi-scale study of non-Gaussianity of Galactic foreground emissions using Minkowski Functionals and generalized skewness-kurtosis parameters, focusing on th…
Morphological complexity of NGC 628 - a multiwavelength multiscale analysis using the ordinal pattern framework
Athokpam Langlen Chanu, S Amrutha, Pravabati Chingangbam +1
As statistical systems, galaxies exhibit a rich interplay between organized structure and stochastic fluctuations across a broad range of spatial scales. This duality motivates the…
Morphological Signatures of Gravitational Evolution, Redshift-Space Distortions, and Massive Neutrinos in Large-Scale Structure
Priya Goyal, Stephen Appleby, Pravabati Chingangbam +1
We investigate the morphological properties of large-scale structure in the Universe and the physical processes that modify the excursion-set morphology of the three-dimensional ma…
The CatWISE2020 Quasar dipole: A Reassessment of the Cosmic Dipole Anomaly
Masroor Bashir, Pravabati Chingangbam, Stephen Appleby
The Ellis-Baldwin test probes the cosmological principle by comparing the kinematic Cosmic Microwave Background dipole with the Doppler-driven dipole in the number counts of extrag…
On the statistical nature of Betti numbers and Euler characteristic of smooth random fields
Pravabati Chingangbam
We represent excursion sets of smooth random fields as unions of a topological basis consisting of a sequence of simply and multiply connected compact subsets of the underlying man…
