Whitaker University of Connecticut N ------------------------------------------------------------------------------------ Abstract We have recently discovered the brightest lensed galaxy known. Rest-frame UV through optical spectra reveal a wealth of spectral diagnostics, providing a unique window on the physical conditions of star formation at the epoch when most stars formed. The major caveat is that at present, we do not know whether this lensed galaxy hosts an AGN that is contributing substantially to the ionizing photon flux, effectively throwing off the nebular line diagnostics. We propose a 40 ks Chandra observation to definitively constrain the X-ray luminosity of an active nucleus, supported by a joint 6 orbit observation with HST to perform complementary UV narrow-band mapping and imaging to support strong lens modeling to interpret the geometry of the lens. ------------------------------------------------------------------------------------ Observations Description ------------------------ The HST data being collected for this program includes optical and near-infrared imaging of the brightest strongly lensed galaxy currently known using the Wide-Field Camera 3 Infrared channel (WFC3/IR). We will collect four imaging bands, spanning the optical through NIR.. The data collected in this program will be combined with imaging in four additional broadband filters and one narrow/medium-band filter, as well as WFC3 prism spectroscopy, from a separate HST program, GO-15101. These HST data will be analyzed jointly with scheduled Chandra X-ray observations of the giant arc, as well as extensive ground-based data. ------------------------------------------------------------------------------------ 15377( 4) - 20-Mar-2019 12:47:03 - [ 2] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 PSZ1-ARC GALAXY, STARBURST RA=15H50M7.0000S, J2000 V = 17.8 R=17.82, z=17.38, J=16.75, DEC=-78D11'32.00" Ks=15.43 (Vega) Reference Frame: ICRS Extended: YES ------------------------------------------------------------------------------------------------------------------------------------ 15377( 4) - 20-Mar-2019 12:47:03 - [ 3] Patterns ------------------------------------------------------------------------------------------------------------------------------------ Pattern_Number: 4 Primary_Pattern Secondary_Pattern Pattern_Type WFC3-UVIS-DITHER-LINE-3PT Pattern_Purpose DITHER Number_Of_Points 3 Point_Spacing 0.135 Line_Spacing Coordinate_Frame POS-TARG Pattern_Orient 46.84 Angle_Between_Sides Center_Pattern NO ------------------------------------------------------------------------------------------------------------------------------------ Pattern_Number: 5 Primary_Pattern Secondary_Pattern Pattern_Type WFC3-IR-DITHER-LINE-3PT Pattern_Purpose DITHER Number_Of_Points 3 Point_Spacing 0.605 Line_Spacing Coordinate_Frame POS-TARG Pattern_Orient 41.788 Angle_Between_Sides Center_Pattern NO ------------------------------------------------------------------------------------------------------------------------------------ Pattern_Number: 6 Primary_Pattern Secondary_Pattern Pattern_Type WFC3-UVIS-DITHER-LINE Pattern_Purpose DITHER Number_Of_Points 2 Point_Spacing 0.145 Line_Spacing Coordinate_Frame POS-TARG Pattern_Orient 46.84 Angle_Between_Sides Center_Pattern NO ------------------------------------------------------------------------------------------------------------------------------------ 15377( 4) - 20-Mar-2019 12:47:03 - [ 4] Visit: 01 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 PSZ1-ARC WFC3/IR MULTIAC IR-FIX F160W NSAMP=10, SAMP-SEQ=SPARS50 1 DEF POS TARG null, -4;
