Description
MWC 148 is a B0pe-type star suspected to be the counterpart of the variable TeV gamma-ray source HESS J0632+057, which also shows variable radio and X-ray emission (Aharonian et al. 2007, A&A, 469, L1; Acciari et al. 2009, ApJ, 698, L94; Hinton et al. 2009, ApJ, 690, L101; Skilton et al. 2009, MNRAS, 399, 317; Falcone et al. 2009, ApJ, 708, L52). MWC 148 is thought to be a gamma-ray binary, although evidence of binarity from radial velocity measurements is still lacking (Aragona et al.

    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
