    Discovery of close binary central stars in the planetary nebulae NGC 6326 and NGC 6778
    We present observations proving the close binary nature of the central stars belonging to the planetary nebulae (PNe) NGC 6326 and NGC 6778. Photometric...

    Discovery of long-period magnetic field oscillations and motions in isolated sunspots
    We analyse the temporal evolution of the inclination component of the magnetic field vector for the penumbral area of 25 isolated sunspots. Compared to previous...

    Discovery of optical and infrared accretion disc wind signatures in the black hole candidate MAXI J1348-630
    MAXI J1348-630 is a low mass X-ray binary discovered in 2019 during a bright outburst. During this event, the system experienced both hard and soft states...

    Discovery of slow X-ray pulsations in the high-mass X-ray binary 4U 2206+54
    Context: The source 4U 2206+54 is one of the most enigmatic high-mass X-ray binaries. In spite of intensive searches, X-ray pulsations have not been detected in...

    Discovery of TeV γ-ray emission from the pulsar wind nebula 3C 58 by MAGIC
    Context. The pulsar wind nebula (PWN) 3C 58 is one of the historical very high-energy (VHE; E> 100 GeV) γ-ray source candidates. It is energized by one of the...

    Discovery of the local counterpart of disc galaxies at z > 4: The oldest thin disc of the Milky Way using Gaia-RVS
    Context. JWST recently detected numerous disc galaxies at high redshifts, and there have been observations of cold disc galaxies at z > 4 with ALMA. In the...
