Their X-ray emission processes have become the source of much debate, with implications for both jet physics and cluster feedback models. 3C111 has an extraordinary 2-arcminute long jet that is seen in X-ray, near-IR and radio. At least 8 knots, plus both approaching and receding hotspots and lobes, are seen in the Chandra image. We request additional Chandra, HST and NuSTAR observations, to follow up on possible evidence of variability in two knots, pin down the knots' X-ray spectrum and SED, detect the jet above 10 keV, and study the morphology and X-ray spectrum of the extended lobes. These observations will place the tightest constraints yet on the physics of this fascinating system. ------------------------------------------------------------------------------------ Observations Description ------------------------ We will obtain images of 3C 111, its jet, hotspots, and lobes with WFC3/IR (F110W, F140W, and F160W). This will allow us to characterize all jet components as well as the hotspots in the near-IR, obtain morphological information, and also optical and broadband spectral energy distributions. The latter will allow the fitting of synchrotron emission models. These observations are to occur within 30 days of the approved Chandra observations (this program was approved in the Chandra review). Two pointings are necessary to image both of the hotspots and lobes given the large angular size of the system. The northern jet pointing (Visit 01) is restricted to an orientation range of 87 to 107 or 122 to 137 degrees in order to include both the AGN core and the hotspot, while avoiding diffraction spikes overlapping the jet. A -90 degree rotation from this would fit everything in the field of view, however there would be a danger of the "Death Star" overlapping the hotspot region, and so we have not included that orientation range. Other rotations of 90 degrees would exclude either the core or the hotspot. In Visit 01, we have added in orbits 2 14849( 4) - 07-Nov-2016 16:16:22 - [ 2] and 3 short exposures on the southern jet in order to obtain an F160W flux of the hotspot only (this integration time is just adequate to obtain 10 sigma on the S hotspot itself). The southern jet pointing (Visit 02) requires a much tighter restriction on the orientation range of 15 degrees (87 to 102 degrees). This is needed to include important regions of the northern jet as well as the southern lobe, while also avoiding the diffraction spike from the AGN core overlapping the jet. A very bright star north of the southern lobe further constricts the orientation range because we cannot have its diffraction spike(s) overlapping the southern hotspot/lobe. This is necessary to constrain the SED of the southern lobe (which is detected in the radio and the X-ray). Due to the tight constraint on the orientation range of the southern pointing, we have separated it into a separate visit to make scheduling easier. ------------------------------------------------------------------------------------ 14849( 4) - 07-Nov-2016 16:16:22 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 3C-111-NORTH GALAXY, ELLIPTICAL, RA=04H18M25.5000S +/- 0.1", J2000 V = 18.05 JET, RADIO GALAXY, DEC=+38D02'2.03" +/- 0.1" SEYFERT Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 2 3C-111-SOUTH GALAXY, ELLIPTICAL, RA=04H18M18.6686S +/- 0.1", J2000 V = 18.05 JET, RADIO GALAXY, DEC=+38D01'21.77" +/- 0.1" SEYFERT Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 3 3C-111-POS3 GALAXY, ELLIPTICAL, RA=04H18M18.8450S +/- 0.1", J2000 V = 18.05 JET, RADIO GALAXY, DEC=+38D01'17.06" +/- 0.1" SEYFERT Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 14849( 4) - 07-Nov-2016 16:16:22 - [ 4] Patterns ------------------------------------------------------------------------------------------------------------------------------------ Pattern_Number: 1 Primary_Pattern Secondary_Pattern Pattern_Type WFC3-IR-DITHER-BLOB WFC3-IR-DITHER-LINE Pattern_Purpose DITHER DITHER Number_Of_Points 2 2 Point_Spacing 5.183 0.636 Line_Spacing Coordinate_Frame POS-TARG POS-TARG Pattern_Orient 41.859 41.788 Angle_Between_Sides Center_Pattern YES NO ------------------------------------------------------------------------------------------------------------------------------------ Pattern_Number: 2 Primary_Pattern Secondary_Pattern Pattern_Type WFC3-IR-DITHER-LINE Pattern_Purpose DITHER Number_Of_Points 2 Point_Spacing 0.636 Line_Spacing Coordinate_Frame POS-TARG Pattern_Orient 41.788 Angle_Between_Sides Center_Pattern NO ------------------------------------------------------------------------------------------------------------------------------------ 14849( 4) - 07-Nov-2016 16:16:22 - [ 5] Visit: 01 Visit Requirements: ORIENT 70D TO 70 D 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 3C-111-NORT WFC3/IR MULTIAC IR F110W SAMP-SEQ=SPARS50, NSAMP=14 1 DEF GS ACQ SCENARIO BASE1B3;
