  • 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

  • The uncertainty of magnetic fields in 3D non-local thermodynamic equilibrium inversions
    We describe our approach to solving the problem of ensuring the solenoidality of the magnetic field vector in 3D inversions, as well as the estimation of the uncertainty in the inferred magnetic field. The solenoidality of the magnetic field vector is often disregarded in the inversion of spectropolarimetric data due to limitations in the

  • The TOI-2427 system: Two close-in planets orbiting a late K-dwarf star
    Using high-precision photometry, NASA's TESS space mission has discovered many intriguing transiting planet candidates. These discoveries require ground-based follow-up observations, including high-precision Doppler spectroscopy, to rule out false positive scenarios and measure the mass of the transiting planets. In this study, we present an
