    Using the Tremaine-Weinberg method to measure pattern speeds from Halpha velocity maps.
    The Tremaine-Weinberg method is a well-known model-independent technique for measuring density wave pattern speeds in spiral galaxies. Here we show how it can...

    UV variability of Fairall-9 (Recondo-Gonzalez+, 1997)
    This is a study of the UV variability of the galaxy Fairall-9 between 1978 and 1991. Table 1 shows the UV continuum fluxes measured in three "line-free" windows...

    UV-extended E-MILES stellar population models: young components in massive early-type galaxies
    We present UV-extended E-MILES stellar population synthesis models covering the spectral range λλ 1680-50 000 Å at moderately high resolution. We employ the...

    VALES I: the molecular gas content in star-forming dusty H-ATLAS galaxies up to z = 0.35
    We present an extragalactic survey using observations from the Atacama Large Millimeter/submillimeter Array (ALMA) to characterize galaxy populations up to z =...

    Variability and evolution of the optical polarization of a sample of gamma-ray blazars
    We present a polarization variability analysis of a sample of 26 γ-ray blazars monitored by the Steward Observatory between 2008 and 2018 in the optical band...

    Variability of the blazar 4C 38.41 (B3 1633+382) from GHz frequencies to GeV energies
    Context. After years of modest optical activity, the quasar-type blazar 4C 38.41 (B3 1633+382) experienced a large outburst in 2011, which was detected...

    Variable stars in Local Group Galaxies - I. Tracing the early chemical enrichment and radial gradients in the Sculptor dSph with RR Lyrae stars
    We identified and characterized the largest (536) RR Lyrae (RRL) sample in a Milky Way dSph satellite (Sculptor) based on optical photometry data collected over...

    Variable stars in Local Group Galaxies - II. Sculptor dSph
    We present the identification of 634 variable stars in the Milky Way dwarf spheroidal (dSph) satellite Sculptor based on archival ground-based optical...
