Description
We report the X-ray detection of Nova Vul 2007 (S. Nakano, IAUC 8861) with the Swift X-ray Telescope in a 6.7ks observation obtained on 2007 October 18 at UT 01:05. The XRT spectrum contains 192 X-ray photons and is largely consistent with a thermal plasma model with temperature kT=0.2 +0.4/-0.07 keV and absorbing column NH=(8 +2/-3)e21 cm^-2. A hotter component with a relative flux a factor of 10 lower and a temperature of kT>1 keV is also required for a statistically acceptable fit to the data.

    NEOMIR: ESA's space-based infrared mission for NEO detection and early warning
    The Near-Earth Object Mission in the Infra-Red (NEOMIR) is the first ESA's space-based mission fully dedicated to discovering near-Earth objects (NEOs), with a focus to detect and raise early warning for the smaller objects that are coming from the Sun direction, thus nearly impossible to be detected by ground-based optical survey. NEOMIR is

    Upgrading the polarisation modulation unit of the Gregor Infrared Spectrograph
    The Gregor Infrared Spectrograph (GRIS) is installed at the Gregor telescope at Observatorio del Teide, Spain. The instrument started observations in 2012 and underwent several upgrades in the following years. Currently, it is experiencing the most significant upgrade so far, which includes, among other things, adding two optical channels to
