Probing Halos of Galaxies at Very Large Radii Using Background QSOs.
Gaseous halos of nine nearby galaxies (with redshifts cz < 6000 km s-1) were probed at large galactocentric radii using background quasars observed with the Hubble Space Telescope Goddard High Resolution Spectrograph and the Space Telescope Imaging Spectrograph. The projected quasar-galaxy separations range from 55 to 387 h75-1 kpc. Lyα absorption lines were successfully detected in the spectra of five quasars, at impact parameters of up to ∼170 h75-1 kpc from the center of the nearby galaxy,...[Show more]
