We will study UV and optical line emission from the knots of a powerful star-forming brightest cluster galaxy from the CLASH MCT cluster sample in order to place definitive limits on the presence of intermediate temperature (10^5-6 K) gas in the center of a massive galaxy that is forming stars at ~100 solar masses per year. We have chosen a galaxy cluster at z~0.35 to enable the first ever simultaneous measurement of O VI, N V, and C IV from a cluster core. We will compare the observed UV line ratios to those predicted by competing model for steady nonequilibrium cooling, thermal conduction, and cooling mediated by turbulent mixing. ------------------------------------------------------------------------------------ Observations Description ------------------------ We plan to acquire STIS (H-alpha, NII) and COS spectroscopy OVI, Lyman-alpha, CIV) of UV-bright knots in the Brightest Cluster Galaxy of a moderate redshift cluster RXJ1532+3021. We have in hand rest-frame UV images f rom the MCT CLASH program so we can accurately position the knots in the STIS aperture. We have a mild constraint that we would like the knots in the COS aperture to be not aligned along the dispersion direction. ------------------------------------------------------------------------------------ 13367( 7) - 02-Jul-2014 10:37:28 - [ 2] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 RXJ1532+3021 CLUSTER OF GALAXIES, RA=15H32M53.7730S +/- 0.1", J2000 Z = V = 18 +/- 0.5 COOLING FLOW, EMISSION DEC=+30D20'59.43" +/- 0.1" 0.362 LINE NEBULA, NUCLEUS, RICH CLUSTER, STAR FORMING REGION Reference Frame: ICRS Comments: The GSC2 coordinates are similar, with larger error budget 0.2". The target, Knot A in the proposal, is GSC2.2 star N13303016375, at 233.224095 + 30.349857. The STIS PA restrictions place the STIS long slit is oriented approximately N/S, and will include Knot B and possibly Knot C (farther south). The restrictions on the COS PA are to avoid lining up Knot A and B (N/S) along the dispersion direction: assumes the dispersion axis "x" is the U3 axis - 45 degrees. It is unlikely both of these knots will be in the sweet spot of the COS aperture simulatenously, however, so even this weak restriction on COS scheduling is probably unnecessary. ------------------------------------------------------------------------------------------------------------------------------------ 2 RXJ1532+3021 CLUSTER OF GALAXIES, RA=15H32M53.7730S +/- 0.1", J2000 Z = V = 18 +/- 0.5 -OFFSET COOLING FLOW, EMISSION DEC=+30D20'59.53" +/- 0.1" 0.362 LINE NEBULA, NUCLEUS, RICH CLUSTER, STAR FORMING REGION Reference Frame: ICRS Comments: The GSC2 coordinates are similar, with larger error budget 0.2". The target, Knot A in the proposal, is GSC2.2 star N13303016375, at 233.224095 + 30.349857. I've provided a position that is 0.1" North of the actual position to avoid centering on Knot B, 0.5" to the south of Knot A. The STIS PA restrictions place the STIS long slit is oriented approximately N/S, and will include Knot B and possibly Knot C (farther south).
