GraphShed: A Data-derived Graph-based waterShed Group Finder
P. Ghafour, S. Ansarifard, M. H. Jalali Kanafi +1
This study introduces GraphShed, a data-derived group-finder that applies top-down watershed segmentation to Voronoi-induced graphs, identifying galaxy systems directly from the de…
Imprint of massive neutrinos on Persistent Homology of large-scale structure
M. H. Jalali Kanafi, S. Ansarifard, S. M. S. Movahed
Exploiting the Persistent Homology technique and its complementary representations, we examine the footprint of summed neutrino mass () in the various density fields simulated…
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…
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…
