This cooling generates strong nebular line radiation in C IV, whose spatial morphology contrasts with that of He II. We propose the first ever, nebular C IV imaging with ACS/SBC to test for these conditions in Mrk 71, a metal-poor (0.1 Z_sun), nearby starburst complex with strong evidence of suppressed superwinds. This system is a uniquely accessible, spatially resolved analog of the Lyman continuum-emitting Green Pea galaxies, a population of cosmological importance, in which suppressed superwinds appear to be relevant. We also propose STIS FUV + optical observations to identify the stellar population of the parent super star cluster Mrk 71-A, which may host very massive stars > 100 M_sun. The STIS long slit will also include a second massive cluster, Mrk 71-B, that is driving a conventional, adiabatic superbubble system; this will allow us to also calibrate classical, adiabatic feedback in this cosmologically important, low-metallicity regime. ------------------------------------------------------------------------------------ Observations Description ------------------------ We carry out deep, C IV 1550 nebular imaging with ACS/SBC using filters F150LP and F165LP. Although these are broadband filters, the shape of their responses redward of ~1650 A is identical, allowing the difference, F150LP - F165LP, to act as a ~150 A-wide filter with an effective wavelength of ~1550 A. F165LP has lower sensitivity, but we must get similar depth. We apply the ACS BOX dither pattern to optimize spatial resolution. The ORIENT is restricted to ensure that the entire Mrk 71 complex, including the superbubble of Knot B, which extends 16261( 5) - 29-Jan-2022 02:20:15 - [ 2] to ~8 arcsec east of Knot A, is included. We specify the same ORIENT for all imaging exposures to optimize coadding. We will also obtain a STIS FUV spectrum with grating G140L covering the range 1150 - 1730 A, using the 0.2 arcsec longslit, aperture 52x0.2. We orient the slit to simultaneously observe Mrk 71-A and Mrk 71-B, which are 5 arcsec apart, dithering along the slit. We do not use aperture D1 so that we can obtain both objects. Finally, we will obtain a STIS CCD spectrum with G430L, also obtaining both Mrk 71-A and B. This will cover the range 2900 - 5700 A. We use the 52x0.2 slit as before, to ensure obtaining both objects. There are extremely bright lines, in particular [O III] 5007, so we take 3 exposures dithered along the slit. The ETC gives a time to saturation of ~1300 sec. ------------------------------------------------------------------------------------ 16261( 5) - 29-Jan-2022 02:20:15 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 MRK71-A EXT-MEDIUM, EMISSION RA=07H28M42.7160S +/- 0.05", J2000 V = 78 V = 17.955 +/- 0.020 F336W = 18.360 +/- LINE NEBULA, HII DEC=+69D11'21.07" +/- 0.05" 0.043 REGION, KNOT, SHELL, STAR FORMING REGION Reference Frame: ICRS Extended: YES Comments: FUV continuum = 4 x 10^-15 erg s^-1 cm^-2 A^-1 arcsec^-2 at 1300 - 1500 A from existing FOS data.
