    The Puzzling Li-Rich Red Giant Associated With Ngc 6819
    A Li-rich red giant (RG) star (2M19411367+4003382) recently discovered in the direction of NGC 6819 belongs to the rare subset of Li-rich stars that have not...

    The puzzling merging cluster Abell 1914: new insights from the kinematics of member galaxies
    We analyse the dynamical state of Abell 1914, a merging cluster hosting a radio halo, quite unusual for its structure. Our study considers spectroscopic data...

    The puzzling orbital period evolution of the LMXB AX J1745.6-2901
    The orbital period evolution of X-ray binaries provides fundamental clues to understanding mechanisms of angular momentum transfer and loss in these systems. We...

    The Puzzling White Dwarf Cooling Sequence in NGC 6791: A Simple Solution
    In this Letter we demonstrate that the puzzling bright peak in the luminosity function of the white dwarf (WD) cooling sequence of NGC 6791 can be naturally...

    The quantity of dark matter in early-type galaxies and its relation to the environment
    We study the behaviour of the dynamical and stellar mass inside the effective radius of early-type galaxies (ETGs) as a function of environment considering...

    The quasar fraction in low-frequency-selected complete samples and implications for unified schemes
    Low-frequency radio surveys are ideal for selecting orientation-independent samples of extragalactic sources because the sample members are selected by virtue...

    The quasar MBH-Mhost relation through cosmic time - I. Data set and black hole masses
    We study the relation as a function of cosmic time in a sample of 96 quasars from z = 3 to the present epoch. In this paper, we describe the sample, the data...

    The quasar MBH-Mhost relation through cosmic time - II. Evidence for evolution from z = 3 to the present age
    We study the dependence of the relation on the redshift up to z = 3 for a sample of 96 quasars, the host galaxy luminosities of which are known. Black hole...

    The quasi-biennial periodicity (QBP) in velocity and intensity helioseismic observations. The seismic QBP over solar cycle 23
    Aims: We looked for signatures of quasi-biennial periodicity (QBP) over different phases of solar cycle by means of acoustic modes of oscillation. Low-degree p...
