Testing Statistical Isotropy on the Sphere with Minkowski Tensors
Stephen Appleby, Changbom Park
We consider how a class of morphological descriptors, the Minkowski Tensors (MTs), can be used to test the statistical isotropy of random fields on the sphere. The definition of th…
Non-Gaussian Expansion of Minkowski Tensors in Redshift Space
Stephen Appleby, Christophe Pichon, Pravabati Chingangbam +2
This paper focuses on extending the use of Minkowski Tensors to analyze anisotropic signals in cosmological data, focusing on those introduced by redshift space distortion. We deri…
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…
Local patch analysis of ACT DR6 convergence map using morphological statistics
Masroor Bashir, Nidharssan S, Pravabati Chingangbam +4
We carry out a comprehensive hierarchical multi-scale morphological analysis to search for anomalous behaviour in the large scale matter distribution using convergence map provided…
Testing Lyman Alpha Emitters and Lyman-Break Galaxies as Tracers of Large-Scale Structures at High Redshifts
Sang Hyeok Im, Ho Seong Hwang, Jaehong Park +21
We test whether Lyman alpha emitters (LAEs) and Lyman-break galaxies (LBGs) can be good tracers of high-z large-scale structures, using the Horizon Run 5 cosmological hydrodynamica…
