During NRL's Far Ultraviolet Cameras experiment on STS-39, four images of the giant reflection nebula encompassing the Upper Scorpius subgroup of the Sco OB2 association were obtained in two ultraviolet bandpasses with lambdaeff = 1362 A and 1769 A. From these images and IUE and TD-1 stellar spectra, the ratio of nebular to stellar flux was calculated. ... The resulting albedos were 0.47-0.70 at 1362 A and 0.55-0.72 at 1769 A. [ ADS ] . ...
ST-ECF Instrument Science Report ACS-2008-01 Updated flux calibration and fringe modelling for the ACS/WFC G800L grism H. Kuntschner, M. KЭmmel, J. R. Walsh January 25, 2008 ABS TRACT A revised flux calibration is presented for the G800L grism with the ACS Wide Field Channel. ... We also include in this report an extensive investigation into the potential effects of fringing on the flux calibration based on the WFC CCDs fringing model as described in ST-ECF ISR ACS 2003-03 (Walsh et al. ...

... Complex astrophysical phenomena could now be studied spectroscopically: the X-ray absorption line forest intrinsic to Seyfert galaxies; the interaction between AGN jets and intracluster media; hot winds of starburst galaxies; stellar coronal plasmas; the charge -exchange emission of Mars' exosphere; the X-ray irradiation of protoplanetary disks; and the myst erious flat-topped spectral line shapes of O star winds. ... We estimate that Gen-X will be able to detect and resolve 20, 000 stars in NGC...
