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…

From QCD-Based Descriptions to Direct Fits: A Unified Study of Nucleon Electromagnetic Form Factors

Hossein Vaziri, Mohammad Reza Shojaei, Pere Masjuan

We present a detailed study of the nucleon electromagnetic form factors in the spacelike region by combining three complementary approaches: two GPD-based contributions and a vecto…

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…

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…

Examining the structure functions of nucleons by introducing new Ansatz and their consequences on parton distribution functions in higher approximation

Hossein Vaziri, Mohammad Reza Shojaei

By introducing ansatz and using a PDF at the approximation in this paper, we have studied the structure of the nucleons in generalized parton distributions (GPDs). For this…
