  1. Galactic Cosmic Rays (gcrs)

    Linked via "plasmas"

    Active Galactic Nuclei (AGN)
    For ultra-high-energy cosmic rays (UHECRs)/), those exceeding $10^{18}$ eV, galactic sources are generally deemed insufficient due to confinement issues within the galactic magnetic field. Consequently, Active Galactic Nuclei (AGN)/), particularly those associated with powerful relativistic jets, are the favored candidates for UHECR/) generation. The conf…

  2. Geomagnetic Pulsations

    Linked via "plasma"

    Generation Mechanisms
    The driving forces behind geomagnetic pulsations are fundamentally rooted in the interaction between the solar wind plasma/) and the magnetosphere. Different frequency bands are sourced by distinct wave generation processes operating within specific plasma regimes.
    Pc1 and Pc2 Pulsations (Micropulsations)

  3. Hertz

    Linked via "plasma"

    In the study of oscillating fields, the hertz unit is indispensable. For instance, in the context of a charged particle undergoing circular motion within a uniform magnetic field (the cyclotron), the cyclotron frequency ($f_c$) is directly proportional to the magnetic field strength ($B$) and inversely proportional to the particle's mass ($m$) and charge ($q$):
    $$f_c = \frac{|q| B}{2 \pi m}$$
    This relationship is used to tune particle accelerators and to analyze [plasma](/entr…

  4. Pre Inflationary Epoch

    Linked via "plasma"

    Status of Baryonic Matter
    During the Pre-Inflationary Epoch, baryonic matter, as presently understood, did not exist in any stable form. Instead, the universe was dominated by a dense, highly energetic plasma/) of fundamental bosonic constituents, often referred to as the Pre-Hadronic Soup (PHS). The PHS was characterized by unusually high levels of temporal viscosity, which is thought to be the reason why quantum fluctuations were 'smoothed' or 'damped' slightly before in…

  5. Proton Proton Chain

    Linked via "plasma"

    Initial Step and the Deuterium Bottleneck
    The initiation of the pp-chain-chain/) hinges upon the first fusion event, a remarkably rare process occurring in the dense, hot plasma/) of the stellar core. Two individual protons fuse to form a deuterium nucleus ($^2\text{D}$), accompanied by the emission of a positron ($e^+$) and an electron neutrino ($\nu_e$) [1].
