The James Webb Space Telescope (JWST) will be launched in 2020. The observations performed with this telescope will revolutionise the field of exoplanet characterisation. The Transiting Exoplanet Community propose to observe the exoplanet WASP-43b in order to better understand the physical structure and the chemical and dynamical processes

We report on the detection of flaring activity from the Fanaroff-Riley I radio galaxy NGC 1275 in very-high-energy (VHE, E > 100 GeV) gamma rays with the Major Atmospheric Gamma Imaging Cherenkov (MAGIC) telescopes. The observations were performed between 2016 September and 2017 February, as part of a monitoring programme. The brightest outburst

Este trabajo de tesis está orientado al estudio de la extracción de información cosmológica de observaciones de la estructura a gran escala del Universo en combinación con medidas del fondo cósmico de microondas. Con este objetivo, la tesis se divide en tres partes fundamentales: la estimación de matrices de covarianza necesarias para la estimación

Hera provides a robust and cost-effective means to perform a planetary defense validation test with a solid balance between risk and innovation. In the frame of the AIDA collaboration, Hera contributes to a truly international planetary defense initiative. It will bring completely new knowledge and insights on asteroid science that will be of great

Aims: The very high energy (VHE ≳100 GeV) γ-ray MAGIC observations of the blazar S4 0954+65, were triggered by an exceptionally high flux state of emission in the optical. This blazar has a disputed redshift of z = 0.368 or z ≥ 0.45 and an uncertain classification among blazar subclasses. The exceptional source state described here makes for an

We present high speed optical photometric observations made using the NTT and ULTRACAM of the optical counterpart of 3XMMJ051034.6-670353, which was recently identified as an X-ray source showing a modulation on a period of 23.6 min. Although the optical counterpart is faint (g = 21.4), we find that the u'g'r' light curves show a periodic
