PI: Dr. Varsha Kulkarni University of South Carolina Research Y Foundation CoI: Dr. Sara Ellison University of Victoria N CoI: Dr. Sebastian Lopez Universidad de Chile N CoI: Mr. Debopam Som University of South Carolina Research Y Foundation ------------------------------------------------------------------------------------ Abstract Absorption lines in quasar spectra offer a powerful tool to study distant galaxies and intergalactic matter (IGM). The strongest of these absorbers, the damped Lyman-alpha (DLA) and sub-DLA absorbers constitute a large fraction of the neutral gas in galaxies. Galaxies located in front of gravitationally lensed quasars (GLQs) are probed by multiple sightlines; so DLA/sub-DLAs in these sightlines can probe the internal structure of interstellar material (ISM) and/or the environment of these galaxies. From the lens galaxy images, impact parameters of the absorbing regions from the galaxy centers can be obtained accurately. Unfortunately, very little information exists on the neutral gas and metal content of DLA/sub-DLAs located in front of GLQs with confirmed lens galaxies. This is because at low redshift where lens galaxies are well-imaged, the H I and key metal lines lie in the UV. Here we propose to study 6 GLQs with known lens redshifts and a total of 14 closely separated double or quadruple images, that show candidate DLA/sub-DLAs along multiple sightlines. Our goal is to measure H I Lyman-alpha absorption in these sightlines. Many of these absorbers are at the lens redshift, with impact parameters 0.6-5.8 kpc. Our observations will therefore allow us to constrain gradients in H I column density and metallicity (combining H I with ground-based metal line measurements) within these galaxies. Our data will also help to constrain the sizes of DLA/sub-DLA absorbing regions by increasing the existing sample of DLA/sub-DLAs probed at < 10 kpc separations by a factor of ~3. HST is essential because of the need for both UV coverage and high spatial resolution. ------------------------------------------------------------------------------------ Observations Description ------------------------ For the doubly imaged GLQs, we will align the two images along the cross-dispersion direction of the 52"x0.2" STIS slit. For the quadruply imaged GLQ, we will obtain spatially resolved spectra of two images at a time. The target coordinates and magnitudes provided are for the brighter of the two targets in each pair. Depending on the foreground absorber redshift, we will use either G230L/NUV-MAMA or G140L/FUV-MAMA to cover the Ly-alpha absorption line. We have calculated the slit orientations using the known RA and DEC separations 13801( 12) - 11-Sep-2014 20:03:58 - [ 2] of the lensed images, and verified them in APT using the "View in Aladdin" option. We have chosen ORIENT ranges of 2 degrees centered on the optimum value needed to line up both images in the 52"x0.2" slit. In cases where specifiying both the desired ORIENT ranges and their 180 degree rotated values leads to an increase in the visit schedulability, we have specified both sets of ranges. For Q1017-207AB, where the ORIENT constraints gave poor schedulability, we have used the special observation requirement "50% schedulability". (While doing so reduces a few minutes of our exposures, it makes the visit more schedulable.) We have checked with the visit planner that all visits are schedulable for at least about 6 weeks. We have verified that there are no other brighter sources within the 5"x5" aperture from the brighter quasar image in each pair of sightlines. We request onboard target acquisitions for all doubly imaged GLQs and for Q2237+030AC. For Q2237+030BD, we request acquisition of image A (listed again as Q2237+030BD-OFFSET), followed by an offset to image B (listed as Q2237+030BD). The coordinates of Q2237+030BD are given in terms of offsets from Q2237+030BD-OFFSET. The coordinates of Q2237+030BD-OFFSET are in the ICRS format. For each orbit, we request 2 spectroscopic exposures, corresponding to 2 positions of a STIS-ALONG-SLIT dither pattern. We use 4 dither patterns, each with 2 positions separated by 1.5", 2.0", 2.5", or 3.0", so as to prevent the spectra of the lensed images in different orbits from falling on the same part of the detector. ------------------------------------------------------------------------------------ 13801( 12) - 11-Sep-2014 20:03:58 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 Q1017-207AB GALAXY, GRAVITATIONAL RA=10H17M23.9630S +/- 0.02S, J2000 Z = V = 17.43 NUV=19.95 LENS, LYMAN ALPHA DEC=-20D46'58.43" +/- 0.30" 2.545 CLOUD, QSO Reference Frame: ICRS Epoch of Position RA proper motion (seconds of time/yr) DEC Proper Motion (arcsec/yr) Annual Parallax (arcsec) 2000.0 0.0 0.0 0.0 ------------------------------------------------------------------------------------------------------------------------------------ 2 SDSSJ1054+27 GALAXY, GRAVITATIONAL RA=10H54M40.8300S +/- 0.5", J2000 Z = V = 17.21 NUV=17.80 33AB LENS, LYMAN ALPHA DEC=+27D33'6.40" +/- 0.5" 1.452 CLOUD, QSO Reference Frame: ICRS Epoch of Position RA proper motion (seconds of time/yr) DEC Proper Motion (arcsec/yr) Annual Parallax (arcsec) 2000.0 0.0 0.0 0.0 ------------------------------------------------------------------------------------------------------------------------------------ 3 SDSSJ1349+12 GALAXY, GRAVITATIONAL RA=13H49M29.8400S +/- 0.5", J2000 Z = V = 17.79 NUV=19.34 27AB LENS, LYMAN ALPHA DEC=+12D27'6.80" +/- 0.5" 1.722 CLOUD, QSO Reference Frame: ICRS Epoch of Position RA proper motion (seconds of time/yr) DEC Proper Motion (arcsec/yr) Annual Parallax (arcsec) 2000.0 0.0 0.0 0.0 ------------------------------------------------------------------------------------------------------------------------------------ 4 Q1355-2257AB GALAXY, GRAVITATIONAL RA=13H55M43.4300S +/- 0.5", J2000 Z = V = 18.2 NUV=18.36 LENS, LYMAN ALPHA DEC=-22D57'23.25" +/- 0.5" 1.373 CLOUD, QSO Reference Frame: ICRS Epoch of Position RA proper motion (seconds of time/yr) DEC Proper Motion (arcsec/yr) Annual Parallax (arcsec) 2000.0 0.0 0.0 0.0 ------------------------------------------------------------------------------------------------------------------------------------ 5 Q2237+030AC GALAXY, GRAVITATIONAL RA=22H40M30.2480S +/- 0.14", J2000 Z = V = 17.35 FUV=20.34 LENS, LYMAN ALPHA DEC=+03D21'30.15" +/- 0.14" 1.695 CLOUD, QSO Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 6 Q2237+030BD GALAXY, GRAVITATIONAL RA-OFF=-0.00018694444444D, J2000 Z = V = 17.47 FUV=21.83 LENS, LYMAN ALPHA DEC-OFF=1.697", FROM 7 1.695 CLOUD, QSO Comments: The offsets are given for image B with respect to image A (which is listed as Q2237+030BD-OFFSET) in this quaduply imaged gravitationally lensed quasar.
