The intermediate age population of the Galactic halo
Mould, Jeremy
We have learned recently that the inner halo of the Milky Way contains a kinematically coherent component (Gaia-Enceladus) from a significant merger 10 Gyrs ago. By contrast the inner (defined to exclude the Magellanic Stream) halo contains no similar intruder stellar population of billion year age. The tracer we use to set the corresponding upper…
Central Wavelengths and Profile Shapes of Diffuse Interstellar Bands versus Physical Parameters of Intervening Clouds
Krełowski, J.; Galazutdinov, G. A.; Marić, T. +2 more
We investigate whether there are variations of the central wavelengths or the profile shapes of diffuse interstellar bands and whether these variations are caused by different physical parameters of translucent clouds. For this purpose we used spectra of two stars seen through two different single clouds: HD 34078 (AE Aur) and HD 73882. The wavele…

Black coatings for combined stray light and thermal passive management for the challenging environmental conditions of Solar Orbiter
Castronuovo, Marco; Schillaci, Tiziano; Montemurro, Luca +4 more
In the context of ESA's Cosmic Vision 2015-2025 scientific program, Solar Orbiter (SolO) represents the first M-class mission, currently under implementation for a launch planned in October 2018.
One of the SolO solar remote-sensing instruments is the Multi Element Telescope for Imaging and Spectroscopy (METIS), under development by an Italia…
Metis/Solar Orbiter polarimetric visible light channel calibration
Romoli, M.; Andretta, V.; Uslenghi, M. +16 more
Metis is the solar coronagraph of the ESA mission Solar Orbiter. For the first time, Metis will acquire simultaneous images of the solar corona in linearly polarized, broadband visible light (580-640 nm) and in the narrow-band HI Ly-α line (121.6 nm). The visible light path includes a polarimeter, designed to observe and analyse the K-corona linea…
Characterization of diffuse X-ray emission from IGR J17448-3232: an implication of a line-of-sight merging activity
Akamatsu, Hiroki; Nobukawa, Kumiko K.; Yamauchi, Shigeo +1 more
The results of spectral analysis for the galaxy cluster IGR J17448-3232 are presented. The intracluster medium (ICM) in the central region (r< 300^' ' }, 320kpc) has a high electron temperature plasma of kT_e ∼ 13-15keV, and an ionization temperature estimated from an intensity ratio of Fe XXVI Lyα /Fe XXV Heα lines is lower than the electron t…
