    Age dating of an early Milky Way merger via asteroseismology of the naked-eye star ν Indi
    Over the course of its history, the Milky Way has ingested multiple smaller satellite galaxies 1. Although these accreted stellar populations can be...

    Age Estimates for Globular Clusters in NGC 1399
    We present high signal-to-noise Keck spectra for 10 globular clusters associated with the giant Fornax elliptical galaxy NGC 1399 and compare measured line...
  • Publication
    Age of Massive Galaxies at Redshift 8
    Recent James Webb Space Telescope data analyses have shown that massive red galaxies existed at redshifts z ≳ 6, a discovery that is difficult to understand in...
  • Publication
    Age-resolved chemistry of red giants in the solar neighbourhood
    In the age of high-resolution spectroscopic stellar surveys of the Milky Way, the number of stars with detailed abundances of multiple elements is rapidly...
  • Publication
    Ages and metallicities of globular clusters in NGC 4472
    We have derived ages and metallicities from co-added spectra of 131 globular clusters associated with the giant elliptical galaxy NGC 4472. Based upon a...
  • Publication
    Ages and metallicities of Hickson compact group galaxies
    Hickson compact groups (HCGs) constitute an interesting extreme in the range of environments in which galaxies are located, as the space density of galaxies in...
  • Publication
    Ages of Galaxies Bulges and Disks From Optical and Near-Infrared Colors
    We compare optical and near-infrared colors of disks and bulges in a diameter-limited sample of inclined, bright, nearby, early-type spirals. Color profiles...
  • Publication
    Ages of LMC star clusters using ASAD2
    We use ASAD2, the new version of ASAD (Analyzer of Spectra for Age Determination), to obtain the age and reddening of 27 Large Magellanic Cloud (LMC) clusters...

    AGILE, Fermi, Swift, and GASP/WEBT multi-wavelength observations of the high-redshift blazar 4C +71.07 in outburst
    Context. The flat-spectrum radio quasar 4C +71.07 is a high-redshift (z = 2.172), γ-loud blazar whose optical emission is dominated by thermal radiation from...
