    Three supernova shells around a young M33 star cluster
    Using a specialized technique sensitive to the presence of expanding ionized gas, we have detected a set of three concentric expanding shells in an H II region...

    Three-dimensional decomposition of galaxies with bulge and long bar
    Context. Some observations indicate that the Milky Way has two inner components, a bulge and a long bar, which present a misalignment of Δα ≃ 20° that is...

    Three-dimensional Spectroscopy of Blue Compact Galaxies: Diagnostic Diagrams
    Here we present the analysis of three-dimensional spectroscopic data of three blue compact galaxies (Mrk 324, Mrk 370, and III Zw 102). Each of the more than 22...

    Through Thick and Thin—H I Absorption in Cosmological Simulations
    We investigate the column density distribution function of neutral hydrogen at redshift z = 3 using a cosmological simulation of galaxy formation from the...

    Tidal Streams in the Galactic Halo: Evidence for the Sagittarius Northern Stream or Traces of a New Nearby Dwarf Galaxy
    Standard cosmology predicts that dwarfs were the first galaxies to be formed in the universe and that many of them merge afterward to form bigger galaxies such...

    Tidally induced velocity gradients in the Milky Way dwarf spheroidal satellites
    We present a kinematic study of six dwarf spheroidal galaxies (dSph) satellites of the Milky Way (MW), namely Carina, Draco, Fornax, Sculptor, Sextans, and Ursa...

    Time Delay in QSO 0957+561 From 1984-1999 Optical Data
    Photometric optical data of QSO 0957+561 covering the period 1984-1999 are analyzed to discern between the two values of the time delay (417 and 424 days)...

    Time Delay of QSO 0957+561 and Cosmological Implications
    We obtain the time delay between the arrival time of the A and B images of the QSO 0957+561. The results of applying two different methods (the discrete cross...

    Time Inference with MUSE in Extragalactic Rings (TIMER): properties of the survey and high-level data products
    The Time Inference with MUSE in Extragalactic Rings (TIMER) project is a survey with the VLT-MUSE integral-field spectrograph of 24 nearby barred galaxies with...
