Graph-based Summary Statistics for Revealing the Stochastic Gravitational Wave Background in Pulsar Timing Arrays
M. Alakhras, S. M. S. Movahed
In this work, we propose a graph-based method implemented on the pulsar timing residuals (PTRs) for stochastic gravitational wave background (SGWB) detection within the nano-Hertz…

Cosmic Strings-induced CMB anisotropies in light of Weighted Morphology
Adeela Afzal, M. Alakhras, M. H. Jalali Kanafi +1
Motivated by the morphological measures in assessing the geometrical and topological properties of a generic cosmological stochastic field, we propose an extension of the weighted…
