    Evidence for Merger-driven Growth in Luminous, High-z, Obscured AGNs in the CANDELS/COSMOS Field
    While major mergers have long been proposed as a driver of both active galactic nucleus (AGN) activity and the {M}{BH}{--}{σ }{bulge} relation, studies of...

    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...

    Evidence for the concurrent growth of thick discs and central mass concentrations from S4G imaging
    We have produced 3.6 μm + 4.5 μm vertically integrated radial luminosity profiles of 69 edge-on galaxies from the Spitzer Survey of Stellar Structure in...

    Evidence for the Disky Origin of Luminous Virgo Dwarf Ellipticals from the Kinematics of Their Globular Cluster Systems
    We report evidence for dynamically significant rotation in the globular cluster systems of two luminous Virgo dwarf ellipticals, VCC1261 and VCC1528. Including...

    Evidence for the Large-Scale Dissociation of Molecular Gas in the Inner Spiral Arms of M81
    We compare the detailed distributions of H I, H alpha , and 150 nm far-UV (FUV) continuum emission in the spiral arms of M81 at a resolution of 9" (linear...

    Evidence for very massive stars in extremely UV-bright star-forming galaxies at z ∼ 2.2-3.6
    We present a comprehensive analysis of the presence of very massive stars (VMS > 100 M ⊙) in the integrated spectra of 13 UV-bright star-forming galaxies at 2.2...

    Evidence of a Distinct Stellar Population in the Counterrotating Core of NGC 1700
    We find a distinct stellar population in the counterrotating and kinematically decoupled core of the isolated massive elliptical galaxy NGC 1700. Coinciding...

    Evidence of a fast bar in the weakly-interacting galaxy NGC 4264 with MUSE
    We present surface photometry and stellar kinematics of NGC 4264, a barred lenticular galaxy in the region of the Virgo Cluster undergoing a tidal interaction...

    Evidence of Parsec-scale Jets in Low-luminosity Active Galactic Nuclei
    The nuclear radio emission of low-luminosity active galactic nuclei (LLAGNs) is often associated with unresolved cores. In this paper we show that most LLAGNs...
