We propose to observe with the HST/COS a complete sample of the nine most metal-deficient (12+logO/H<7.25) compact SFGs known in the local universe, to obtain medium-resolution spectra of the Ly-alpha emission line. Only one galaxy with such a low metallicity, I Zw 18, has been studied previously with the HST/COS. These SFGs were selected from the Data Release 16 and earlier releases of the Sloan Digital Sky Survey to be not only XMD, but also to be very compact and to have very young starbursts (EW(Hbeta)>100A). Among them one galaxy, J0811+4730 with 12+logO/H = 6.98, is one of the lowest-metallicity low-z SFG known to date. The Ly-alpha profiles in those medium resolution spectra will be used to indirectly estimate the escape fraction of the Lyman continuum and will provide important insight on the ISM and radiation field of the star-forming regions. Obtaining the rest-UV spectra of these nine XMD SFGs which will serve as templates for the analysis of spectra of high-z dwarf galaxies with active star formation, is thus both urgent and crucial for upcoming studies with the JWST and the largest ground-based facilities. ------------------------------------------------------------------------------------ Observations Description ------------------------ The galaxies are faint and satisfy safety conditions for observing with the COS. Furthermore, there are no sources brighter than the COS safety limits in circular regions with the diameter of 43 arcsec centered on the selected galaxies. NUV acquisition images of the targets will be obtained with the standard Mirror A and the ACQ/IMAGE mode to reach a S/N20 inside a 9x9 pixel box centered on the brightest part of the galaxy. The adopted GALEX NUV magnitudes were used to estimate exposure times. The angular galaxy radius is chosen to be 0.2", inside which most of the galaxy light is concentrated. The total time for acquisition is up to 120s+2x700s=1520s per object (HST Primer manual), or half of orbit. As a bonus, the UV morphology of the selected 16672( 4) - 20-Jul-2021 11:55:32 - [ 2] objects will be studied with these images. For medium-resolution spectroscopy, the COS in combination with the G130M grating will be used to observe the Ly-alpha line. This resolution is required to resolve the Ly-alpha line profile and to measure features such as the velocity separations between different emission peaks which give the best estimate of the LyC escape fraction. The Ly-alpha emission-line profiles in the spectra of the proposed galaxies will be compared to those in LyC leaking galaxies and in Green Pea galaxies. The GALEX FUV magnitude is used to calculate for each object the required number of orbits to obtain a S/N > 5 for the continuum near Ly-alpha line, in the case of a 100-pixel binned spectrum. This S/N would be enough to obtain the Ly-alpha profile with a sufficient accuracy for radiative transfer modeling and for deriving velocity separations between the peaks. For each target, 0.5 orbit for acquisition, and 2.5 or 3.5 orbits for the spectrum with the medium-resolution G130M grating are needed, totalling 3 or 4 orbits per object. A total of 34 orbits for 9 objects is requested. ------------------------------------------------------------------------------------ 16672( 4) - 20-Jul-2021 11:55:32 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 J0122+0048 GALAXY, DWARF COMPACT, RA=01H22M41.6108S +/- 0.2", J2000 Z = V = 21.62 +/- 0.05 FUV=21.51+/-0.09, STARBURST DEC=+00D48'41.98" +/- 0.2" 0.0574 NUV=21.46+/-0.10 Reference Frame: ICRS Extended: NO ------------------------------------------------------------------------------------------------------------------------------------ 2 J0139+1542 GALAXY, DWARF COMPACT, RA=01H39M11.9300S +/- 0.2", J2000 Z = V = 21.84 +/- 0.05 NUV=22.17+/-0.15 STARBURST DEC=+15D42'41.32" +/- 0.2" 0.0281 Reference Frame: ICRS Extended: NO ------------------------------------------------------------------------------------------------------------------------------------ 3 J0811+4730 GALAXY, DWARF COMPACT, RA=08H11M52.1300S +/- 0.2", J2000 Z = V = 21.37 +/- 0.05 FUV=21.00+/-0.40, STARBURST DEC=+47D30'26.24" +/- 0.2" 0.0444 NUV=21.90+/-0.40 Reference Frame: ICRS Extended: NO ------------------------------------------------------------------------------------------------------------------------------------ 4 J0837+1921 GALAXY, DWARF COMPACT, RA=08H37M21.8700S +/- 0.2", J2000 Z = V = 21.91 +/- 0.06 FUV=21.25+/-0.33, STARBURST DEC=+19D21'10.63" +/- 0.2" 0.0673 NUV=21.53+/-0.49 Reference Frame: ICRS Extended: NO ------------------------------------------------------------------------------------------------------------------------------------ 5 J1004+3256 GALAXY, DWARF COMPACT, RA=10H04M9.9100S +/- 0.2", J2000 Z = V = 21.33 +/- 0.05 NUV=22.35+/-0.18 STARBURST DEC=+32D56'12.51" +/- 0.2" 0.0664 Reference Frame: ICRS Extended: NO ------------------------------------------------------------------------------------------------------------------------------------ 6 J1206+5007 GALAXY, DWARF COMPACT, RA=12H06M8.5200S +/- 0.2", J2000 Z = V = 21.76 +/- 0.05 FUV=22.28+/-0.14, STARBURST DEC=+50D07'21.10" +/- 0.2" 0.0514 NUV=22.25+/-0.12 Reference Frame: ICRS Extended: NO ------------------------------------------------------------------------------------------------------------------------------------ 7 J1234+3901 GALAXY, DWARF COMPACT, RA=12H34M15.7100S +/- 0.2", J2000 Z = V = 21.92 +/- 0.06 FUV=21.24+/-0.38, STARBURST DEC=+39D01'16.41" +/- 0.2" 0.1329 NUV=22.17+/-0.57 Reference Frame: ICRS Extended: NO ------------------------------------------------------------------------------------------------------------------------------------ 8 J1505+3721 GALAXY, DWARF COMPACT, RA=15H05M8.5800S +/- 0.2", J2000 Z = V = 20.97 +/- 0.06 FUV=21.54+/-0.32, STARBURST DEC=+37D21'40.22" +/- 0.2" 0.0753 NUV=21.29+/-0.18 Reference Frame: ICRS Extended: NO ------------------------------------------------------------------------------------------------------------------------------------ 9 J2229+2725 GALAXY, DWARF COMPACT, RA=22H29M33.1900S +/- 0.2", J2000 Z = V = 21.47 +/- 0.06 FUV=21.45+/-0.28, STARBURST DEC=+27D25'25.60" +/- 0.2" 0.0762 NUV=21.88+/-0.37 Reference Frame: ICRS Extended: NO ------------------------------------------------------------------------------------------------------------------------------------ 16672( 4) -
