PI: Prof. Crystal Martin University of California - Santa Barbara Y CoI: Dr. Mark Dijkstra Max-Planck-Institut fur Astrophysik N ------------------------------------------------------------------------------------ Abstract Observations of the hydrogen Lya profile in galaxy spectra uniquely distinguish outflowing and inflowing gas. Recent COS observations of ultraluminous starbursts show the telltale signature of infalling neutral hydrogen. A radiative transfer calculation that models the profiles of Lyman series lines predicts broad scattering wings on the hydrogen Balmer lines, but the origin of the scattered Balmer emission is only unique when the Lyb profile is also fit. We show a strong kinematic similarity between the broad wings of the Lya and Ha line profiles in ULIRG spectra raising the suggestion that the sign of the gas flows producing the broad Ha wings may have been previously misinterpreted. We propose very blue G130M spectroscopy with COS to obtain the Lyb line profiles for four starburst galaxies with the aim of establishing the correct interpretation of the broad Balmer line wings in starburst spectra. Radiative transfer modeling has focused primarily on reproducing the Lya line shape. Calculating the Lya and Ha line profiles simultaneously in principle eliminates degenercies in model parameters. However, the addition of spectroscopy covering Lyb can significantly improve the constraints obtained from radiative transfer modeling; but because of the lack of data, no one has done this thus far. The Hubble Utraviolet Initiative should ensure that these data exist. ------------------------------------------------------------------------------------ Observations Description ------------------------ This program will obtain pre-imaging of 2 ULIRGs. Blind offsets between the UV brightest knot in the ULIRG and a nearby star will be calculated from these images and used to acquire the UV knot in the COS PSA. COS G130M spectra will be obtained for each ULIRG. The other two ULIRGs have known offsets and can be acquired with existing information. The new COS spectra will provide bluer coverage than did previous observations.
