Description
Based on a 5ks Chandra ACIS-I observation of M31 on Nov 11 2009, we report a dramatic brightening of CXOM31 J004321.1+411751, [aka r3-7 (Kong et al. 2002 ApJ 577, 738), source 437 (Pietsch, Freyberg, and Haberl 2005 A&A 434, 483), RX J0043.3+4117 (Supper et al. 2001 A&A 373, 63)]. The spectrum on Nov 11 can be well fit with a power law with photon index 2.1 ± 0.2 and Nh consistent with the Galactic value of 7E20 cm-2.

    Detector upgrade in EMIR@GTC: on-sky performances
    EMIR was shipped to the GTC on May 2016 and had its first light on June 2016. Since the beginning, the EMIR performances have been severely hampered by the many instabilities in the infrared detector, a 2048x2048 Hawaii2, built with the old original technology of the Teledyne Hawaii series. Despite of this, the instrument has proven to be powerful

    The Large Interferometer For Exoplanets (LIFE) is a proposed space mission that enables the spectral characterization of the thermal emission of exoplanets in the solar neighborhood. The mission is designed to search for global atmospheric biosignatures on dozens of temperate terrestrial exoplanets and it will naturally investigate the diversity of
