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 ACS-2006-02 Wavelength and Flux calibration of the ACS/SBC PR110L and PR130L prisms S. S. Larsen, February 2006 ABSTRACT Wavelength- and flux calibrations are presented for the ACS/SBC PR110L and PR130L slitless spectroscopy modes. ... Wavelength. ...
