    Bright Points in the Internetwork Quiet Sun
    High-resolution G-band images of the interior of a supergranulation cell show ubiquitous bright points (BPs; some 0.3 BPs per Mm2). They are located in...

    Buried in the noise.
    As astrophysicists, we are used to extracting physical information from the observations. The usual procedure is to propose a parametric physical model to...

    Center-to-limb variation of the area covered by magnetic bright points in the quiet Sun
    Context. The quiet Sun magnetic fields produce ubiquitous bright points (BPs) that cover a significant fraction of the solar surface. Their contribution to the...

    Channeling 5 Minute Photospheric Oscillations into the Solar Outer Atmosphere through Small-Scale Vertical Magnetic Flux Tubes
    We report two-dimensional MHD simulations which demonstrate that photospheric 5 minute oscillations can leak into the chromosphere inside small-scale vertical...
