    Euclid: High-precision imaging astrometry and photometry from Early Release Observations: I. Internal kinematics of NGC6397 by combining Euclid and Gaia data
    The instruments at the focus of the Euclid space observatory offer superb, diffraction-limited imaging over an unprecedented (from space) wide field of view of...

    Everything that glitters is not gold: V1315 Cas is not a dormant black hole
    The quest for quiet or dormant black holes has been ongoing since several decades. Ellipsoidal variables possibly indicate the existence of a very high-mass...

    Evidence for a black hole in the historical X-ray transient A 1524-61 (= KY TrA)
    We present Very Large Telescope spectroscopy, high-resolution imaging, and time-resolved photometry of KY TrA, the optical counterpart to the X-ray binary A...

    Evidence for a metal-poor population in the inner Galactic bulge
    The inner Galactic bulge has, until recently, been avoided in chemical evolution studies because of extreme extinction and stellar crowding. Large, near-IR...

    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...

    Evidence for Evolved Stellar Binary Mergers in Observed B-type Blue Supergiants
    Blue supergiants are the brightest stars in their host galaxies, and yet their evolutionary status has been a long-standing problem in stellar astrophysics. In...

    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...

    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 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...
