The ESA Cosmic Vision “Euclid" mission will conduct a 6-years long survey of 15,000 square degrees of the sky to a look-back time of 10 billion years, with the aim of characterizing the matter-energy content of the Universe and to better understand

We present SOFIA/FIFI-LS observations of the [CII] 158${\mu}$m cooling line across the nearby spiral galaxy NGC 6946. We combine these with UV, IR, CO, and H I data to compare [CII] emission to dust properties, star formation rate (SFR), H$_2$, and H

Publikováno v: Journal of Astronomical Instrumentation

We describe the design of the Field-Imaging Far-Infrared Line Spectrometer (FIFI-LS), operated as a Facility-Class instrument on the Stratospheric Observatory for Infrared Astronomy (SOFIA). FIFI-LS is an imaging spectrometer for medium resolution sp
