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…
Cosmic Environment as the Primary Driver of Dwarf Satellite Statistics
Saeed Tavasoli, Parsa Ghafour
Context: Satellite dwarf galaxies provide key constraints on galaxy formation and evolution, since their abundance and spatial distribution reflect both the host properties and the…
The Filament Rift: CDM's Structural Challenge Against Observation
Saeed Tavasoli, Parsa Ghafour
This study presents the first extended comparison of cosmic filaments identified in SDSS DR10 observations () and the IllustrisTNG300-1 CDM simulation (), utili…
From Voids to Clusters: Mergers and Evolutionary Pathways of Star-Forming and Quenched Low-Mass Galaxies
Mohammad Reza Shojaei, Saeed Tavasoli, Parsa Ghafour
The evolution of low-mass galaxies is shaped by both internal processes and environmental factors, yet the role of environment and mergers in regulating their growth and star forma…
GrAviPaSt's Lens to the Past: Unveiling the Evolution of Filamentary Structures
Parsa Ghafour, Saeed Tavasoli
This paper examines the evolution of cosmic filaments across redshifts 1, 0.5, and 0 using the IllustrisTNG100-1 magneto-hydrodynamical simulation. To achieve this, we introduce Gr…
Star-Forming vs. Quenched Galaxies in Voids: Insights into the Role of Mergers
Mohammad Reza Shojaei, Saeed Tavasoli, Parsa Ghafour
Cosmic voids, the largest under-dense structures in the Universe, are crucial for exploring galaxy evolution. These vast, sparsely populated regions are home to void galaxies -- pr…
VEGA: Voids idEntification using Genetic Algorithm
P. Ghafour, S. Tavasoli, M. R. Shojaei
Cosmic voids are large, nearly empty regions that lie between the web of galaxies, filaments and walls, and are recognized for their extensive applications in the field of cosmolog…
