  • Investigation of the Effect of Density Gradients in Fuel Pellets on Filamentation Electromagnetic Instability during Beam-Plasma Interactions in Inertial Confinement Fusion 

    Mahdavi, Mohammad؛ Bizhani, Zeinab؛ Khanzadeh, Hengameh (Damghan University Astronomical Society of Iranدانشگاه دامغان, 2025-01-01)
    The transfer of a beam of high-energy particles, such as electrons, to the center of a fuel pellet is a significant aspect of plasma fusion processes. When the beam is directed toward the center of the fuel pellet, a ...

  • Magnetic Braking of the Rotational Molecular Cloud Cores, Revisited 

    Ebrahimi, Abbas؛ Nejad-Asghar, Mohsen (Damghan University Astronomical Society of Iranدانشگاه دامغان, 2025-01-01)
    The phenomenon of magnetic braking is one of the significant physical effects of the magnetic field in rotating molecular clouds. Here, we revisit the work of Nakano (1989). In addition to receiving his results, we investigate ...

  • Observational Status of Zero-Point Length Cosmic Inflation 

    Pourmohseni, Elahe؛ Nozari, Kourosh؛ Nassiri-Rad, Amin (Damghan University Astronomical Society of Iranدانشگاه دامغان, 2025-01-01)
    We examine observational status of cosmological inflation with a zero-point length. By considering the zero-point length correction to the geometric part of the field equations, specially the Hubble parameter, we derive ...

  • On the Generation and Dissipation of Magnetic Energy During a Shear-Flow Driven Instability in Space Plasmas 

    Hosseinpour, Mahboub (Damghan University Astronomical Society of Iranدانشگاه دامغان, 2025-01-01)
    A well-known shear flow-driven instability, namely the Kelvin‐Helmholtz instability (KHI), establishes important changes in the macroscopic dynamics of some space magnetized plasmas such as the solar corona, astrophysical ...

  • Dark Energy Evolution: Non-Interacting and Interacting Cases 

    Noori Gashti, Saeed؛ Alipour, Mohammad Reza؛ Afshar, Mohammad Ali S.؛ Sadeghi, Jafar (Damghan University Astronomical Society of Iranدانشگاه دامغان, 2025-01-01)
    In this paper, we study dark energy from two different perspectives, challenging a two-field scenario in two forms: non-interacting and interacting. We investigate the evolution of dark energy in a Friedmann-Robertson-Walker ...
