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…
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…
Which filaments matter: the relative scalings of anisotropic infall
Junsup Shim, Dmitri Pogosyan, Myoungwon Jeon +1
Dark-matter haloes do not form in isolation but within the surrounding cosmic web. By the time a halo begins to collapse, its larger-scale environment has typically collapsed along…
Recovering 3D Magnetic Turbulence from Single-Frequency Faraday Screens
Aliaksandr Melnichenka, Alex Lazarian, Dmitri Pogosyan
Statistics of polarized synchrotron radiation carry information about the properties of the underlying turbulence. Different statistical measures constructed from observables probe…
On Stability and Isotropization of Kasner Solution in Gravity
Dmitri Pogosyan, Akash Kav
The fate of the Universe that initially expands anisotropically in the theory with quantum-gravitational term in the Lagrangian is investigated. The stability of Kasner-lik…
Influence of Density Distribution on Synchrotron Polarization Dispersion in Magnetized Interstellar Medium
Yawen Xiao, Jianfu Zhang, Alex Lazarian +1
Faraday rotation measure (RM) synthesis is a well-known approach originated in Burn (1966) and later developed by Brentjens \& de Bruyn (2005) for studying magnetic fields. This wo…
