    Dissecting the stellar content of Leo I: a dwarf irregular caught in transition
    Leo I is considered one of the youngest dwarf spheroidals (dSph) in the Local Group. Its isolation, extended star formation history (SFH), and recent...

    Distant trans-Neptunian object candidates from NASA's TESS mission scrutinized: fainter than predicted or false positives?
    NASA's Transiting Exoplanet Survey Satellite (TESS) is performing a homogeneous survey of the sky from space in search of transiting exoplanets. The collected...

    Diversity of dwarf galaxy IR-submm emission patterns: CLUES from hydrodynamical simulations
    Context. The spectral energy distributions (SEDs) of low-mass low-metallicity (dwarf) galaxies are a challenging piece of the puzzle of galaxy formation in the...

    Do AGN triggering mechanisms vary with radio power? - I. Optical morphologies of radio-intermediate HERGs
    Active galactic nuclei (AGNs) with intermediate radio powers are capable of driving multiphase outflows in galaxy bulges, and are also more common than their...

    Do galaxies form a spectroscopic sequence?
    We identify a spectroscopic sequence of galaxies, analogous to the Hubble sequence of morphological types, based on the Automatic Spectroscopic K-means-based...

    Downflowing umbral flashes as evidence of standing waves in sunspot umbrae
    Context. Umbral flashes are sudden brightenings commonly visible in the core of some chromospheric lines. Theoretical and numerical modeling suggests that they...

    Dust properties of double-tailed active asteroid (6478) Gault
    Context. Asteroid (6478) Gault was discovered to exhibit a comet-like tail in observations from December 2018, becoming a new member of the so-called active...
