  • The GAPS programme at TNG. XLIX. TOI-5398, the youngest compact multi-planet system composed of an inner sub-Neptune and an outer warm Saturn

    Context. Short-period giant planets (P ≲ 10 days, Mp >0.1 MJ) are frequently found to be solitary compared to other classes of exo-planets. Small inner companions to giant planets with P ≲ 15 days are known only in five compact systems: WASP-47, Kepler-730, WASP-132, TOI-1130, and TOI-2000. Here, we report the confirmation of TOI-5398, the youngest

  • The hydrostatic-to-lensing mass bias from resolved X-ray and optical-IR data

    An accurate reconstruction of galaxy cluster masses is key to use this population of objects as a cosmological probe. In this work we present a study on the hydrostatic-to-lensing mass scaling relation for a sample of 53 clusters whose masses were reconstructed homogeneously in a redshift range between z = 0.05 and 1.07. The M500 mass for each

  • Detection of an intranight optical hard lag with colour variability in blazar PKS 0735+178

    Blazars are a highly variable subclass of active galactic nuclei that have been observed to vary significantly during a single night. This intranight variability remains a debated phenomenon, with various mechanisms proposed to explain the behaviour including jet energy density evolution or system geometric changes. We present the results of an

  • Orbit of the Patroclus–Menoetius Binary System and Predictions for the 2024/2025 Mutual Events Season

    We report on the ephemeris development for Menoetius, the satellite of Patroclus. Our data set consisted of ground–based and Hubble Space Telescope relative astrometry, as well as 42 lightcurves from the mutual events seasons in 2007, 2012, and 2017/2018. Our dynamical model included the effects of oblate, nonspherical shapes of the components, and

  • CHARACTERIZING EXOPLANET ATMOSPHERES WITH HIGH-RESOLUTION SPECTROGRAPHS

    En los últimos años, el descubrimiento de exoplanetas ha incrementado exponencialmente. Actualmente, se conocen más de 5000 planetas extrasolares y para 77 de ellos se han detectado señales atmosféricas utilizando observaciones de baja y alta resolución espectral. Una de las maneras más efectivas de estudiar las atmósferas exoplanetarias está

  • EXPLORING THE COSMOS THROUGH A LENS: SEARCHING FOR STRONGLY-LENSED SUPERNOVAE IN TIME-DOMAIN SURVEYS

    La constante de Hubble (H0) es un parámetro crítico en cosmología que define propiedades esenciales del universo, como su tamaño, edad, tasa de expansión y densidad crítica. A pesar de su importancia, determinar un valor preciso para H0 sigue siendo un tema de debate en el campo de la cosmología. Se han utilizado varios métodos para medir H0 dentro
