We have reanalyzed the Large Magellanic Cloud's (LMC) ultraviolet (UV) extinction using data from the IUE final archive. Our new analysis takes advantage of the improved signal-to-noise ratio of the IUE NEWSIPS reduction, the exclusion of stars with very low reddening, the careful selection of well-matched comparison stars, and an analysis of the effects of Galactic foreground dust. ...

CORES OR CUSPS IN ELLIPTICAL GALAXIES: LUMINOSITY OR ENVIRONMENT? ... The low lumi nosity disky galaxies have `hard' cores with a steep slope in the luminosity profile at small radii, whereas the luminous galaxies have `soft' cores with flat profiles at small radii (e.g. Faber et al. ... Coma Cluster cores In the gas/stellar continuum paradigm, one would expect that in the outer parts of a cluster it is more likely that the last merger was gaseous than in its central regions. ...
ST-ECF Instrument Science Report WFC3-2008-15 The TV2 ground calibrations of the WFC3 NIR grisms H. Kuntschner, H. Bushouse, J. R. Walsh, M. KЭmmel July 08, 2008 ABS TRACT Based on thermal vacuum tests (TV2; June - August 2007), the performance of the WFC3 near-IR G102 and G141 grisms has been assessed. ... The setup for G141 is identical. ... 10 ST-ECF Instrument Science Report WFC3-2008-15 Figure 5: Instrument efficiency of various orders for the WFC3 G141 grism as function of wavelength. ...

... 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...
