    Euclid: Early Release Observations – Programme overview and pipeline for compact- and diffuse-emission photometry
    The Euclid Early Release Observations (ERO) showcase Euclid's capabilities in advance of its main mission by targeting 17 astronomical objects, including galaxy...
  • Publication
    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...

    Euclid: Testing photometric selection of emission-line galaxy targets
    Multi-object spectroscopic galaxy surveys typically make use of photometric and colour criteria to select their targets. That is not the case of Euclid, which...
  • Publication
    Evaluating quenching in cosmological simulations of galaxy formation with spectral covariance in the optical window
    Cosmological hydrodynamical simulations provide valuable insights on galaxy evolution when coupled with observational data. Comparisons with real galaxies are...

    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 stellar contamination in the transmission spectra of HAT-P-12b
    Context. Transmission spectroscopy characterizes the wavelength dependence of transit depth, revealing atmospheric absorption features in planetary terminator...

    Evidence for transit-timing variations of the 11 Myr exoplanet TOI-1227 b
    TOI-1227 b is an 11 Myr old validated transiting planet in the middle of its contraction phase, with a current radius of 0.85 R j. It orbits a low-mass pre-main...

    Evidence of intra-binary shock emission from the redback pulsar PSR J1048+2339
    We present simultaneous multiwavelength observations of the 4.66 ms redback pulsar PSR J1048+2339. We performed phase-resolved spectroscopy with the Very Large...

    Examining the orbital decay targets KELT-9 b, KELT-16 b, and WASP-4b, and the transit-timing variations of HD 97658 b
    Context. Tidal orbital decay is suspected to occur for hot Jupiters in particular, with the only observationally confirmed case of this being WASP-12b. By...
