  • A Hα metric for identifying dormant black holes in X-ray transients
    Dormant black holes in X-ray transients can be identified by the presence of broad Hα emission lines from quiescent accretion discs. Unfortunately, short-period cataclysmic variables can also produce broad Hα lines, especially when viewed at high inclinations, and are thus a major source of contamination. Here we compare the full width at half

  • A comprehensive study on radial velocity signals using ESPRESSO: Pushing precision to the 10 cm/s level
    Aims. We analyse ESPRESSO data for the stars HD 10700 (τ Ceti), HD 20794 (e Eridani), HD 102365, and HD 304636 acquired via its Guaranteed Time Observations (GTO) programme. We characterise the stars' radial velocity (RV) signals down to a precision of 10 cm/s on timescales ranging from minutes to planetary periods falling within the host's

  • A comprehensive look at PUDG-R21: stellar population and kinematics of a globular cluster-rich ultra-diffuse galaxy in the Perseus Cluster
    We present the analysis of the stellar populations and kinematics of the globular cluster (GC)-rich ultra-diffuse galaxy (UDG), PUDG-R21, using spectroscopic observations obtained with the Keck Cosmic Web Imager. The recessional velocity is measured to be 5536 $\pm$ 10 km s ‑1, confirming its association with the Perseus Cluster. The galaxy

  • Two neighbours of the ultra-short-period Earth-sized planet K2-157 b in the warm Neptunian savanna
    Context. The formation and evolution of ultra-short-period (USP) rocky planets is poorly understood. However, it is widely thought that these planets could not have formed at their present-day close-in orbits, but instead migrated inwards through interactions with outer neighbours. Aims. We aim to confirm and characterise the USP Earth-sized

  • TP-AGB stars and stellar population properties of a post-starburst galaxy at z ∼ 2 through optical and near-infrared spectroscopy with JWST
    We present a detailed optical and near-IR (NIR) spectral analysis of J-138717, a post-starburst galaxy at z = 1.8845 observed with JWST/NIRSpec, for which we derive a stellar mass of 3.5±0.2×10 10 M ⊙ and a stellar velocity dispersion of 198±10 km s ‑1. We estimate an age of ∼0.9 Gyr and a subsolar metallicity (between ‑0.4 and ‑0.2 dex). We find

  • TOI-2407 b: a warm Neptune in the desert
    We present the validation of TOI-2407 b, a warm Neptune-sized planet with a radius of $4.26\pm 0.26$ R $_{\oplus }$, orbiting an early M-type star with a period of 2.7 d and an equilibrium temperature of $705\pm 12$ K. The planet was identified by Transiting Exoplanet Survey Satellite (TESS) photometry and validated in this work through
