    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...

    The Quest for Microwave Foreground X
    The Wilkinson Microwave Anisotropy Probe (WMAP) team has produced a foreground map that can account for most of the low-frequency Galactic microwave emission in...

    The quest for the solar g modes
    Solar gravity modes (or g modes)—oscillations of the solar interior on which buoyancy acts as the restoring force—have the potential to provide unprecedented...

    The QUEST RR Lyrae Survey. I. The First Catalog
    With the 1 m Schmidt telescope of the Llano del Hato Observatory and the QUEST CCD camera, 380 deg2 of the sky have been surveyed for RR Lyrae variables in a...
