    Slipping reconnection in a solar flare observed in high resolution with the GREGOR solar telescope
    A small flare ribbon above a sunspot umbra in active region 12205 was observed on November 7, 2014, at 12:00 UT in the blue imaging channel of the 1.5 m GREGOR...

    Small-scale magnetic flux emergence in a sunspot light bridge
    Context. Light bridges are convective intrusions in sunspots that often show enhanced chromospheric activity. Aims: We seek to determine the nature of flux...

    Small-scale magnetic flux emergence preceding a chain of energetic solar atmospheric events
    Context. Advancements in instrumentation have revealed a multitude of small-scale extreme-ultraviolet (EUV) events in the solar atmosphere and considerable...

    Smooth kinematic and metallicity gradients reveal that the Milky Way's nuclear star cluster and disc might be part of the same structure
    Context. The innermost regions of most galaxies are characterised by the presence of extremely dense nuclear star clusters. Nevertheless, these clusters are not...

    SN 2012aa: A transient between Type Ibc core-collapse and superluminous supernovae
    Context. Research on supernovae (SNe) over the past decade has confirmed that there is a distinct class of events which are much more luminous (by 2 mag) than...

    Soft X-ray to far infrared luminosities ratio in star-forming galaxies: predictions from synthesis models
    Context: A good correlation has been found in star-forming galaxies, between the soft X-ray and the far infrared or radio luminosities. The soft X-ray emission...
