Fricke Universitats-Sternwarte Gottingen N ------------------------------------------------------------------------------------ Abstract One of the key questions in observational cosmology is the identification of the sources responsible for cosmic reionization. The general consensus is that a population of faint low-mass and low-metallicity galaxies must be responsible for the bulk of the ionizing photons at high redshifts. However, for a long time, attempts at identifying individual galaxies showing Lyman continuum (LyC) leakage have only found very few such galaxies, both at high and low redshifts. A breakthrough was achieved in the last few years by Izotov et al. (2016ab, 2018ab, 2021), who detected LyC emission in 15 out of 20 low-z (z~0.3) compact star-forming galaxies (SFG) with LyC escape fractions of 2-72%, using HST/COS observations. Furthermore, a Large Program of COS observations of 66 z~0.3-0.4 SFGs with the LyC detections in ~50 SFGs has been completed. However, almost all these SFGs have 12+logO/H>7.7, while it is expected that lower-metallicity galaxies were the main sources of the reionization of the Universe. It is proposed here to extend the previous studies to a sample of eight compact SFGs at z~0.3-0.4 at lower metallicities 12+logO/H~7.45-7.70 derived by a direct method, a range almost not explored before by HST/COS. This will allow us to study how LyC escape varies with metallicity in a larger range. The observations will also allow for the determination of the Ly-alpha line profile, providing an empirical probe of this robust indirect LyC leakage indicator for a wide range of metallicities. Since these low- metallicity compact SFGs share many properties with typical SFGs at high redshift, this study will provide important insight on the sources of reionization of the early Universe. ------------------------------------------------------------------------------------ Observations Description ------------------------ The selected galaxies are sufficiently faint to 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'' centered on the selected galaxies. NUV acquisition images of the targets will be obtained with 17109( 3) - 14-Jun-2024 15:17:39 - [ 2] the standard Mirror A and the ACQ/IMAGE mode, with exposures of 300 seconds to reach a S/N~20 inside a 9x9 pixel box centered on the brightest part of the galaxy. The GALEX NUV magnitudes were adopted to estimate the S/N. 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+2x300s=720s per object. As a bonus, it will be possible to study the UV morphology of the selected objects with these images. The COS will be used in combination with the following 2 gratings: 1) the low-resolution G140L grating centered at 800A to measure the LyC. The required number of orbits for each object is calculated so as to detect the LyC at the level above 1sigma with a 100-pixel binning of the data at the observed wavelength near 912x(1+z) Angstrom. For the LyC, an escape fraction of 5% and the intrinsic LyC flux density obtained from the relation I(Hbeta)/I(912)~10A are adopted, where I(Hbeta) is the extinction-corrected flux of the Hbeta emission line; 2) the medium-resolution G160M grating to observe the Ly-alpha line with an observed resolution better than 50 km/s, sufficient to separate blue and red peaks. The required number of orbits to obtain a S/N > 1 in the continuum near Ly-alpha line for a 10-pixel binned spectrum is derived adopting a flux density at the wavelength 1216x(1+z) Angstrom obtained from the SED fit of the optical spectrum. This S/N would be enough to obtain the Ly-alpha profile with a sufficient accuracy for measurements of peak separation and radiative transfer modeling. Each target needs 0.3 orbit for acquisition, 1.5 orbits for the spectrum with the medium-resolution G160M grating, and 2 orbits per object (for the six brightest galaxies with FUV < 21.5 mag) or 3 orbits per object (for the remaining two galaxies) for the spectrum with the low-resolution G140L grating, totalling 4 or 5 orbits per object. We request a total of 34 orbits for 8 objects. ------------------------------------------------------------------------------------ 17109( 3) - 14-Jun-2024 15:17:39 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 J0021+3117 GALAXY, DWARF COMPACT, RA=00H21M28.9900S +/- 0.2", J2000 Z = V = 21.93 +/- 0.05 FUV=21.47+/-0.20, STARBURST DEC=+31D17'26.41" +/- 0.2" 0.32211 NUV=21.63+/-0.43, F(1216*(1+z)=1608A)=4.7e-17 erg/s/cm2/A, intrinsic F(912*(1+z)=1206A)=8.7e-17 erg/s/cm2/A Reference Frame: ICRS Extended: NO ------------------------------------------------------------------------------------------------------------------------------------ 2 J0131+2242 GALAXY, DWARF COMPACT, RA=01H31M17.8000S +/- 0.2", J2000 Z = V = 22.39 +/- 0.05 FUV=21.64+/-0.20, STARBURST DEC=+22D42'9.22" +/- 0.2" 0.31625 NUV=22.02+/-0.32, F(1216*(1+z)=1600A)=7.3e-17 erg/s/cm2/A, intrinsic F(912*(1+z)=1200A)=5.6e-17 erg/s/cm2/A Reference Frame: ICRS Extended: NO ------------------------------------------------------------------------------------------------------------------------------------ 3 J0238+0003 GALAXY, DWARF COMPACT, RA=02H38M10.5000S +/- 0.2", J2000 Z = V = 21.89 +/- 0.05 FUV=21.20+/-0.20, STARBURST DEC=+00D03'26.68" +/- 0.2" 0.37448 NUV=21.71+/-0.23, F(1216*(1+z)=1671A)=1.3e-16 erg/s/cm2/A, intrinsic F(912*(1+z)=1254)=9.7e-17 erg/s/cm2/A Reference Frame: ICRS Extended: NO ------------------------------------------------------------------------------------------------------------------------------------ 4 J1247+3154 GALAXY, DWARF COMPACT, RA=12H47M3.1400S +/- 0.2", J2000 Z = V = 22.45 +/- 0.05 FUV=20.83+/-0.20, STARBURST DEC=+31D54'55.09" +/- 0.2" 0.35592 NUV=20.98+/-0.20, F(1216*(1+z)=1649A)=1.8e-16 erg/s/cm2/A, intrinsic F(912*(1+z)=1238)=9.0e-17 erg/s/cm2/A Reference Frame: ICRS Extended: NO ------------------------------------------------------------------------------------------------------------------------------------ 5 J1340+5448 GALAXY, DWARF COMPACT, RA=13H40M2.5600S +/- 0.2", J2000 Z = V = 20.98 +/- 0.05 FUV=22.07+/-0.20, STARBURST DEC=+54D48'54.81" +/- 0.2" 0.37795 NUV=22.08+/-0.20, F(1216*(1+z)=1675A)=5.7e-17 erg/s/cm2/A, intrinsic F(912*(1+z)=1257)=3.3e-17 erg/s/cm2/A Reference Frame: ICRS Extended: NO ------------------------------------------------------------------------------------------------------------------------------------ 6 J1607+3217 GALAXY, DWARF COMPACT, RA=16H07M45.6800S +/- 0.2", J2000 Z = V = 21.59 +/- 0.05 FUV=20.33+/-0.20, STARBURST DEC=+32D17'51.96" +/- 0.2" 0.30118 NUV=20.36+/-0.20, F(1216*(1+z)=1582A)=3.3e-16 erg/s/cm2/A, intrinsic F(912*(1+z)=1187)=2.4e-16 erg/s/cm2/A Reference Frame: ICRS Extended: NO ------------------------------------------------------------------------------------------------------------------------------------ 7 J1638+3348 GALAXY, DWARF COMPACT, RA=16H38M10.3800S +/- 0.2", J2000 Z = V = 22.16 +/- 0.05 FUV=21.93+/-0.35, STARBURST DEC=+33D49'31.09" +/- 0.2" 0.30890 NUV=21.59+/-0.20, F(1216*(1+z)=1592A)=1.1e-16 erg/s/cm2/A, intrinsic F(912*(1+z)=1194)=8.7e-17 erg/s/cm2/A Reference Frame: ICRS Extended: NO ------------------------------------------------------------------------------------------------------------------------------------ 17109( 3) -
