White University of Alabama N ------------------------------------------------------------------------------------ Abstract Fossil groups (FGs) are thought to be the end product of ancient isolated galaxy groups that have been allowed to evolve in time, to the point where most luminous members have fallen to the center of the potential and merged into one bright elliptical which dominates the remaining members. While FGs have been well studied, little has been done in the way of their progenitors. By using the CASSOWARY catalog of gravitational lens systems found in the Sloan Digital Sky Survey, we have identified one group which appears to be a recent FG and seven that show strong evidence of being FG progenitors at various stages in their evolution. X-ray data would allow us to see the formation processes of FGs at various epochs and see how they change as the FG is assembled. ------------------------------------------------------------------------------------ Observations Description ------------------------ To conduct our observations, we request use of the ACS WFC for three observations per filter (F475W, F606W, and F814W) for each of our four strong lensing targets: CSWA 26, CSWA 30, CSWA 11, and CSWA 14. For our brightest targets, we allocate two orbits each to CSWA 26, CSWA 30, and CSWA 11. Due to CSWA 14's high redshift, we allocate to it the three remaining orbits, as deeper observations are needed to bring out the more distant gravitational arc structure and inner regions of the central galaxy. This comes to a grand total of nine orbits. These are straightforward observations, and no special roll angle is required. ------------------------------------------------------------------------------------ 14362( 2) - 15-Oct-2015 11:56:07 - [ 2] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 KAA2009-SDSS CLUSTER OF GALAXIES, RA=11H13M10.7000S, J2000 Z = V = 18.2 -J1113+2356 GRAVITATIONAL LENS, DEC=+23D56'39.00" 0.336 GROUP Reference Frame: Other: SIMBAD Extended: YES Comments: This object was generated by the targetselector and retrieved from the SIMBAD database. ------------------------------------------------------------------------------------------------------------------------------------ 2 CSWA-30 CLUSTER OF GALAXIES, RA=08H51M26.5000S, J2000 Z = V = 18.7 GRAVITATIONAL LENS, DEC=+35D58'13.80" 0.272 GROUP Reference Frame: Other: SIMBAD Extended: YES Comments: This object was generated by the targetselector and retrieved from the SIMBAD database. ------------------------------------------------------------------------------------------------------------------------------------ 3 CSWA-11 CLUSTER OF GALAXIES, RA=08H00M13.0600S, J2000 V = 19.3 GRAVITATIONAL LENS, DEC=+08D12'8.40" GROUP Reference Frame: Other: SIMBAD Comments: This object was generated by the targetselector and retrieved from the SIMBAD database. ------------------------------------------------------------------------------------------------------------------------------------ 4 CSWA-14 CLUSTER OF GALAXIES, RA=17H23M36.2000S, J2000 V = 20.1 GRAVITATIONAL LENS, DEC=+34D11'58.10" GROUP Reference Frame: Other: SIMBAD Comments: This object was generated by the targetselector and retrieved from the SIMBAD database. ------------------------------------------------------------------------------------------------------------------------------------ 14362( 2) -
