Whitaker University of Connecticut N ------------------------------------------------------------------------------------ Abstract We propose for Chandra imaging of the hot intra-cluster gas in a unique new sample of 29 galaxy clusters selected purely on their strong gravitational lensing signatures. This will be the first program targeting a purely strong lensing selected cluster sample, enabling new comparisons between the ICM properties and scaling relations of strong lensing and mass/ICM selected cluster samples. Chandra imaging, combined with high precision strong lens models, ensures powerful constraints on the distribution and state of matter in the cluster cores. This represents a novel angle from which we can address the role played by baryonic physics, the infamous gastrophysics, in shaping the cores of massive clusters, and opens up an exciting new galaxy cluster discovery space with Chandra. ------------------------------------------------------------------------------------ Observations Description ------------------------ In this program we will obtain similar HST data for the three strong lensing galaxy clusters. These data will reveal the morphologies of member galaxies in these clusters, while also providing constraints on the strong lensing properties of the clusters by revealing multiply imaged background sources. Observations of two clusters will include two optical and two near-infrared (NIR) imaging bands, while the third cluster will receive two NIR imaging bands (to be used alongside existing archival HST optical imaging). All observations will be performed with the Wide-Field Camera 3 Infrared channel (WFC3/UVIS and WFC3/IR). The objective for each strong lensing galaxy cluster is to select the four broadband filters to optimally span important spectral breaks (i.e., the 4000A break and the Lyman-break) in the spectral energy distributions (SEDs) of both foreground cluster galaxies, and in background strongly lensed sources. ------------------------------------------------------------------------------------ 15378( 3) - 14-Sep-2017 19:34:55 - [ 2] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 MACSJ1226+21 CLUSTER OF GALAXIES, RA=12H26M50.7000S, J2000 V = 19.3 giant arc has g=21.1 and r, i 52 GRAVITATIONAL LENS DEC=+21D52'11.00" = 20.7 Reference Frame: ICRS Extended: YES ------------------------------------------------------------------------------------------------------------------------------------ 2 SDSSJ1429+12 CLUSTER OF GALAXIES, RA=14H29M54.8000S, J2000 V = 20.5 giant arc has g, r, i ~ 20.7 02 GRAVITATIONAL LENS DEC=+12D02'35.60" Reference Frame: ICRS Extended: YES ------------------------------------------------------------------------------------------------------------------------------------ 3 SDSSJ1458-00 CLUSTER OF GALAXIES, RA=14H58M36.1200S, J2000 V = 20.0 giant arc has g=22.9, and r, i 24 GRAVITATIONAL LENS DEC=-00D23'57.98" =22 (AB) Reference Frame: ICRS Extended: YES ------------------------------------------------------------------------------------------------------------------------------------ 15378( 3) - 14-Sep-2017 19:34:55 - [ 3] Patterns ------------------------------------------------------------------------------------------------------------------------------------ Pattern_Number: 1 Primary_Pattern Secondary_Pattern Pattern_Type WFC3-UVIS-MOS-DITH-LINE WFC3-UVIS-MOS-DITH-LINE Pattern_Purpose MOSAIC DITHER Number_Of_Points 2 2 Point_Spacing 2.4 0.119 Line_Spacing Coordinate_Frame POS-TARG POS-TARG Pattern_Orient 85.754 33.606 Angle_Between_Sides Center_Pattern YES NO ------------------------------------------------------------------------------------------------------------------------------------ Pattern_Number: 2 Primary_Pattern Secondary_Pattern Pattern_Type WFC3-IR-DITHER-BOX-MIN Pattern_Purpose DITHER Number_Of_Points 4 Point_Spacing 0.572 Line_Spacing 0.365 Coordinate_Frame POS-TARG Pattern_Orient 18.528 Angle_Between_Sides 74.653 Center_Pattern NO ------------------------------------------------------------------------------------------------------------------------------------ 15378( 3) - 14-Sep-2017 19:34:55 - [ 4] Visit: 01 (SDSSJ1458-0024) Visit Requirements: On Hold Comments: Additional Comments: Exposures ------------------------------------------------------------------------------------------------------------------------------------ Exp | Target | Instr | Oper. | Aper |Spectral|Central| Optional |Num| Time | Special Num | Name | Config | Mode | or FOV |Element |Waveln.| Parameters |Exp| (Total) | Requirements ------------------------------------------------------------------------------------------------------------------------------------ 1 SDSSJ1458-0 WFC3/IR MULTIAC IR-FIX F160W NSAMP=14, SAMP-SEQ=SPARS25 1 DEF POS TARG null, 23.5;
