Description
We report the serendipitous discovery of a high-excitation nebula in the Local Group dwarf galaxy IC 1613. The nebula shows spectral features typical of a planetary nebula (PN), but its physical size makes it an order of magnitude larger than observed for this type of object, if indeed it belongs to IC 1613. We hypothesise that it may be an example of an over-luminous PN, a still unexplained phenomenon that deserves further investigation.

    Massive characterisation of subgiants and red giants with TESS (Kepler and Gaia)
    TESS serves as a formidable tool for investigating stellar variability. Nonetheless, the adaptation of methodologies employed in other space missions, such as Kepler, to deduce long stellar rotation periods or solar-like stellar pulsations has been a challenge. The advent of multiple sectors of data for most stars every two years with the extended

    Kepler meets Gaia: Binary systems, color-magnitude diagram, and kinematic analysis
    The Kepler mission has delivered unprecedented high-quality photometry. These data have impacted numerous research fields including Galactic studies, asteroseismology, and exoplanets, and continue to be an astrophysical gold mine to this day. Because of this, thorough investigations of the ∼200,000 stars observed by Kepler remain of paramount

    Gas Flows in the Central Region of NGC 4593 with Muse
    Understanding how gas flows into galactic centers, fuels the AGN and in turn is expelled back through feedback processes is of great importance to appreciate the role AGN play in the growth and evolution of galaxies. We use MUSE-AO optical spectra of the inner 7''. 5 × 7''. 5 of the nearby Seyfert 1 galaxy NGC 4593 to understand how gas flows in
