    Fast infrared winds during the radio-loud and X-ray obscured stages of the black hole transient GRS 1915+105
    The black hole transient GRS 1915+105 entered a new phase of activity in 2018, generally characterised by low X-ray and radio fluxes. This phase has only been...

    Fast magnetohydrodynamic oscillations in a force-free line-tied coronal arcade
    Aims.We discuss a simple model of a line-tied coronal arcade with piecewise constant density to explore the effects of curvature on radially polarised fast...

    Fast magnetohydrodynamic oscillations in a multifibril Cartesian prominence model
    Observations of quiescent filaments show very fine structures which suggests that they can be composed of small-scale threads or fibrils. Two-dimensional, high...

    Fast magnetohydrodynamic oscillations in an elliptical coronal arcade
    Aims.A model of a elliptically shaped coronal arcade with piecewise constant density is discussed to explore the effects of curvature on radially polarised fast...

    Fast magnetohydrodynamic waves in a two-slab coronal structure: collective behaviour
    Aims.We study fast magnetohydrodynamic waves in a system of two coronal loops modeled as smoothed, dense plasma slabs in a uniform magnetic field. This allows...

    Fast MHD oscillations in line-tied homogeneous coronal loops
    Loop oscillations have been abundantly reported in recent years. Earlier analytical studies of loop oscillations consider freely propagating waves, allowing for...

    Fast MHD oscillations in prominence fine structures
    High-resolution observations suggest that quiescent solar prominences are made of small-scale fibrils stacked one after another in both the vertical and...

    Fast MHD oscillations of a 3-dimensional prominence fibril
    High-resolution observations of quiescent filaments point out that their fine structure is made of small-scale threads or fibrils. These fibrils can be...

    Fast quasi-periodic oscillations in the eclipsing polar VV Puppis from VLT and XMM-Newton observations
    We present high time resolution optical photometric data of the polar VV Puppis obtained simultaneously in three filters (u', HeII λ4686, r') with the ULTRACAM...
