    Fast Magnetohydrodynamic Oscillations in Cylindrical Prominence Fibrils
    Some observations suggest that quiescent solar prominences can be considered as composed by small-scale loops, or fibrils, which are stacked one after another...

    Fast Multipole Method for Gravitational Lensing: Application to High-magnification Quasar Microlensing
    We introduce the use of the fast multipole method (FMM) to speed up gravitational lensing ray tracing calculations. The method allows very fast calculation of...

    Fast-to-Alfvén Mode Conversion and Ambipolar Heating in Structured Media. I. Simplified Cold Plasma Model
    Linear fast magnetoacoustic waves are introduced into a cold stratified plasma model made up of a doubly periodic ensemble of straight diminished-Alfvén-speed...

    Fast-to-Alfvén Mode Conversion in the Presence of Ambipolar Diffusion
    It is known that fast magnetohydrodynamic waves partially convert to upward and/or downward propagating Alfvén waves in a stratified atmosphere where Alfvén...

    Fast-to-Alfvén Mode Conversion Mediated by Hall Current. II. Application to the Solar Atmosphere
    Coupling between fast magnetoacoustic and Alfvén waves can be observed in fully ionized plasmas mediated by stratification and 3D geometrical effects. In Paper...

    Fast-to-Alfvén Mode Conversion Mediated by the Hall Current. I. Cold Plasma Model
    The photospheric temperature minimum in the Sun and solar-like stars is very weakly ionized, with an ionization fraction f as low as 10‑4. In galactic star...

    Fermi Large Area Telescope Observations of Markarian 421: The Missing Piece of its Spectral Energy Distribution
    We report on the γ-ray activity of the high-synchrotron-peaked BL Lacertae object Markarian 421 (Mrk 421) during the first 1.5 years of Fermi operation, from...
