Planck Limits on Cosmic String Tension Using Machine Learning
M. Torki, H. Hajizadeh, M. Farhang +2
We develop two parallel machine-learning pipelines to estimate the contribution of cosmic strings (CSs), conveniently encoded in their tension (), to the anisotropies of the co…
Cosmological consequences of intrinsic alignments super-sample covariance
Saeed Ansarifard, S. M. S. Movahed
We examine cosmological constraints from high precision weak lensing surveys including super-sample covariance (SSC) due to the finite survey volume. Specifically, we focus on the…
Birefringent Graphene Oxide Liquid Crystals in Micro-channels for Optical Switch
M. Arshadi Pirlar, Y. Honarmand, M. Rezaei Mirghaed +2
We propose a mechanical-hydrodynamical experimental setup in which the microfluidic motion manipulates the optical birefringence of levitated graphene oxide liquid crystal. The bir…
Clustering of Local Extrema in Planck CMB maps
A. Vafaei Sadr, S. M. S. Movahed
The clustering of local extrema will be exploited to examine Gaussianity, asymmetry, and the footprint of the cosmic-string network on the CMB observed by Planck. The number densit…
CMB Cold Spot in the Planck light
Marzieh Farhang, M. Sadegh Movahed
The Cold Spot, with an unusually cold region surrounded by a hot ring, is a statistically significant anomaly in the Cosmic Microwave Background (CMB) sky. In this work we assess w…
The Three Hundred Project: correcting for the hydrostatic-equilibrium mass bias in X-ray and SZ surveys
S. Ansarifard, E. Rasia, V. Biffi +8
Accurate and precise measurements of masses of galaxy clusters are key to derive robust constraints on cosmological parameters. Rising evidence from observations, however, confirms…
