TL;DR: The Stratospheric Observatory for Infrared Astronomy (SOFIA) is an airborne observatory consisting of a specially modified Boeing 747SP with a 2.7 m telescope, flying at altitudes as high as 13.7 km (45,000 ft) as discussed by the authors.
Journal ArticleDOI
[C II] 158 μm Luminosities and Star Formation Rate in Dusty Starbursts and Active Galactic Nuclei
L. Sargsyan,Vianney Lebouteiller,Dan Weedman,Henrik Spoon,Jeronimo Bernard-Salas,D. Engels,G. Stacey,J. R. Houck,Don Barry,J. W. Miles,A. Samsonyan +10 more
TL;DR: In this article, a calibration of star formation rate (SFR) for the starburst component in any source having [C II] was derived with the result that log SFR = log L(C II)]) − 7.08 ± 0.3, for SFR in M ☉ yr-1 and L([C II]) in L ☉.
Journal ArticleDOI
Wavelength Dependence of the Helioseismic and Magnetic Imager (HMI) Instrument onboard the Solar Dynamics Observatory (SDO)
Sebastien Couvidat,Jesper Schou,Richard A. Shine,R. I. Bush,J. W. Miles,Philip H. Scherrer,Richard L. Rairden +6 more
TL;DR: In this paper, the authors present a series of wavelength-dependent calibration tests performed on the HMI optical-filter system from 2005 to 2012 to obtain the transmittances as a function of wavelength for the tunable and non-tunable filter elements.
Journal ArticleDOI
