PI: Dr. John M. O'Meara Saint Michaels College Y CoI: Dr. Jeff Cooke Swinburne University of Technology Y ------------------------------------------------------------------------------------ Abstract The damped Lyman alpha systems (DLAs, log (NHI) >= 20.3) seen in absorption toward distant quasars have been studied for over 40 years, yet two of their most fundamental properties, namely their size and their mass, have remained elusive. Sightlines to QSOs probe only a fraction of a parsec of the area of the DLAs. Although methods currently exist to measure DLA spatial extents, they trace only their star forming regions (direct imaging), only their rest frame optical extents (IFU searches), or offer only pencil beam piece-wise sampling (close background quasar pair spectra). In this proposal, we present a new technique to directly constrain the size of the neutral hydrogen gas absorption in the DLA via their detection in the spectra of background galaxies. We have a pilot sample of 3 DLAs seen in the spectra of z~3 galaxies, and require HST+WFC3 images to obtain the spatial extent of these galaxies. Doing so will increase our knowledge of the spatial extent of DLA gas by a factor of at least 10^8 over present measures. ------------------------------------------------------------------------------------ Observations Description ------------------------ We will obtain imaging in 5 F390W orbits and 2 F606W orbits for 3 target galaxies EG1, EG2, and EG3 using WFC3+UVIS ------------------------------------------------------------------------------------ 14160( 6) - 30-Jul-2015 19:33:15 - [ 2] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 EG1 GALAXY, HIGH REDSHIFT RA=02H26M54.7000S, J2000 V = 24.5 GALAXY DEC=-04D18'45.54" Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 2 EG2 GALAXY, HIGH REDSHIFT RA=14H20M32.1680S, J2000 V = 23.75 GALAXY DEC=+52D53'0.86" Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 3 EG3 GALAXY, HIGH REDSHIFT RA=02H26M36.3460S, J2000 V = 23.66 GALAXY DEC=-04D19'0.64" Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 14160( 6) - 30-Jul-2015 19:33:15 - [ 3] Patterns ------------------------------------------------------------------------------------------------------------------------------------ Pattern_Number: 1 Primary_Pattern Secondary_Pattern Pattern_Type WFC3-UVIS-GAP-LINE Pattern_Purpose MOSAIC Number_Of_Points 2 Point_Spacing 2.414 Line_Spacing Coordinate_Frame POS-TARG Pattern_Orient 85.759 Angle_Between_Sides Center_Pattern YES ------------------------------------------------------------------------------------------------------------------------------------ 14160( 6) - 30-Jul-2015 19:33:15 - [ 4] Visit: 01 Visit Requirements: ORIENT 12D TO 37 D;
