Observations from the HERschel Inventory of the Agents of Galaxy Evolution (HERITAGE) have been used to identify dusty populations of sources in the Large and Small Magellanic Clouds (LMC and SMC). We conducted the study using the HERITAGE catalogs of point sources available from the Herschel Science Center from both the Photodetector Array Camera and Spectrometer (PACS; 100 and 160 ЮМm) and Spectral and Photometric Imaging Receiver (SPIRE; 250, 350, and 500 ЮМm) cameras. ...
ST-ECF Instrument Science Report ACS 2001-002 The Effective Spectral Resolution of the WFC and HRC Grism A. Pasquali, N. Pirzkal, J.R. Walsh, R.N. Hook, W. Freudling, R. Albrecht, R.A.E. Fosbury March 7, 2001 ABSTRACT We present SLIM simulations of the size and orientation with respect to by which the object extension along resolution of the grism. ... In the case of ACS, the nominal spectral resolution is 40 е/pix and 29 е/pix in the first order spectra of the WFC and HRC grism, respectively. ...
... 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...
