Science with hot astrophysical plasmas
Urdampilleta, I.; Kaastra, J. S.; Mernier, F. +5 more
We present some recent highlights and prospects for the study of hot astrophysical plasmas. Hot plasmas can be studied primarily through their X-ray emission and absorption. Most astrophysical objects, from solar system objects to the largest scale structures of the Universe, contain hot gas. In general we can distinguish collisionally ionised gas…
Gaia, an all sky astrometric and photometric survey
Carrasco, J. M.
Gaia space mission includes a low resolution spectroscopic instrument to classify and parametrize the observed sources. Gaia is a full-sky unbiased survey down to about 20th magnitude. The scanning law yields a rather uniform coverage of the sky over the full mission. The data reduction is a global one over the full mission. Both sky coverage and …
Proton radiation damage assessment of a CCD for use in a Ultraviolet and Visible Spectrometer
Hathi, B.; Patel, M.; Gow, J. P. D. +2 more
This paper describes the radiation environment and radiation damage analysis performed for the Nadir and Occultation for MArs Discovery (NOMAD) Ultraviolet and Visible Spectrometer (UVIS) channel launched onboard the ExoMars Trace Gas Orbiter (TGO) in 2016. The aim of the instrument is to map the temporal and spatial variation of trace gases such …
