    CTAO LST─1 observations of magnetar SGR 1935+2154: Deep limits on sub-second bursts and persistent tera-electronvolt emission
    Context. The Galactic magnetar SGR 1935+2154 has exhibited prolific high-energy (HE) bursting activity in recent years. Aims. Investigating its potential tera...

    Cu and Zn in the early Galaxy
    We present Cu and Zn abundances for 38 FGK stars, mostly dwarfs, spanning a metallicity range between solar and [Fe/H] = -3. The abundances were obtained using...

    Cyclic brightening in the short-period WZ Sge-type cataclysmic variable SDSS J080434.20+510349.2
    Aims: We observed a new cataclysmic variable (CV) SDSS J080434.20+510349.2 to study the origin of long-term variability found in its light curve. Methods: Multi...

    Damped transverse oscillations of interacting coronal loops
    Damped transverse oscillations of magnetic loops are routinely observed in the solar corona. This phenomenon is interpreted as standing kink magnetohydrodynamic...

    Damping of prominence longitudinal oscillations due to mass accretion
    We study the damping of longitudinal oscillations of a prominence thread caused by the mass accretion. We suggested a simple model describing this phenomenon...

    Dark Energy Survey Deep Field photometric redshift performance and training incompleteness assessment
    Context. The determination of accurate photometric redshifts (photo-zs) in large imaging galaxy surveys is key for cosmological studies. One of the most common...

    Dark energy versus Ωm = 1 in the growth of matter perturbations
    We explore the possibility of discriminating dark energy models from the study of the growth of matter perturbations. For the sake of simplicity, instead of...

    Dark matter response to galaxy assembly history
    Aims: It is well known that the presence of baryons affects the dark matter host haloes. Exploring the galaxy assembly history together with the dark matter...
