... The grand design nature of M81 is clearly seen, showing two well-resolved spiral arms containing numerous bright star-forming regions. ... We investigate the variation of the ultraviolet (UV), HЮБ, and infrared (IR) luminosities and star formation rate (SFR) indicators across the face of M81 using the MIPS images and archival UV and HЮБ images. ... The behavior of the infrared-radio correlation in M81 is seen to vary from the global average, with variations correlated with the morphology of M81. ...
ST-ECF Instrument Science Report ACS 2001-003 ACS Grism Simulations using SLIM 1.0 N. Pirzkal, A. Pasquali, J. R. Walsh, R. N. Hook, W. Freudling, R. Albrecht, R.A.E. Fosbury April 4, 2001 ABSTRACT We introduce SLIM, a slitless spectroscopy simulator written in Python which can be used to simulate the ACS grism and prism modes. ... We have thus developed a simulator called SLIM which is able to disperse an input spectrum in a well-controlled manner. ... Can simulate multiple order grism observations. ...
... 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...
