... HST is subjected to cosmic rays and protons from the Earth's radiation belts. ... Cosmic ray events usually deposit significant quantities of charge in more than one pixel. ... Figure 4.7 shows a histogram of the number of affected pixels for each cosmic ray event. ... Cosmic ray events do have a clear lower cutoff at around 500 electrons of total signal. ... The number of pixels affected by cosmic ray events in a given exposure is a slightly more sensitive function of the threshold used. ...

... The science from both these missions contributed to three of the Nobel Prizes Giacconi (2002), Mather, and Smoot (2006) - awarded for NASA-based science. ... We encourage NASA to seek new launch capabilities to fill this strategic gap in moderate lift rockets to enable the Explorer program to continue launching missions with significant science payoff but reduced costs and timescales compared to large strategic missions. ... 18 Appendix B: Explorer Missions 1989-present (From PILMSS) No . ...

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. ...
