    Evidence for Blue Straggler Stars Rejuvenating the Integrated Spectra of Globular Clusters
    Integrated spectroscopy is the method of choice for deriving the ages of unresolved stellar systems. However, hot stellar evolutionary stages, such as hot...
  • Publication
    Evidence for Population-dependent Vertical Motions and the Long-lived Nonsteady Lopsided Milky Way Warp
    We present a Galactic disk vertical velocity analysis using OB type stars (OB stars), red clump (RC) stars, and main-sequence turnoff (MSTO) stars with...
  • Publication
    Evidence for temporal evolution in the M33 disc as traced by its star clusters
    We present precision radial velocities and stellar population parameters for 77 star clusters in the Local Group galaxy M33. Our Gran Telescopio de Canarias and...
  • Publication
    Evidence for the Naphthalene Cation in a Region of the Interstellar Medium with Anomalous Microwave Emission
    We report high-resolution spectroscopy of the moderately reddened (AV=3) early-type star Cernis 52 located in a region of the Perseus molecular cloud complex...
  • Publication
    Evolution of tidal disruption candidates discovered by XMM-Newton
    Context: It has been demonstrated that active galactic nuclei are powered by gas accretion onto supermassive black holes located at their centres. The paradigm...
  • Publication
    Evolutionary and pulsation properties of Type II Cepheids
    We discuss the observed pulsation properties of Type II Cepheids (TIICs) in the Galaxy and in the Magellanic Clouds. We found that period (P) distributions...
  • Publication
    Evolutionary stellar population synthesis with MILES - II. Scaled-solar and α-enhanced models
    We present models that predict spectra of old- and intermediate-aged stellar populations at 2.51 Å (FWHM) with varying [α/Fe] abundance. The models are based on...
  • Publication
    Evolved stars in the Local Group galaxies - II. AGB, RSG stars, and dust production in IC10
    We study the evolved stellar population of the Local Group galaxy IC10, with the aim of characterizing the individual sources observed and to derive global...
  • Publication
    Evolved stars in the Local Group galaxies - III. AGB and RSG stars in Sextans A
    We study the evolved stellar population of the galaxy Sextans A. This galaxy is one of the lowest metallicity dwarfs in which variable asymptotic giant branch...
