Available Spectra For Sighline H1821

All columns except the last one are sortable by clicking on the column headers. The last column contains links to download the spectral FITS files for each epoch ("TELESCOPE" + "-" + "EPOCH NUMBER".) All masses are in units of solar masses. "Rho" is the impact parameter between the galaxy and AGN sight line positions, while "logMh" is the halo mass. Note that redshifts are reported for galaxies that are near AGN sight lines, even if they are not foreground to the AGN (i.e., z_gal > z_AGN), but they are not flagged specifically. Absorption flag values have the following meanings:

  • -2: no COS spectrum available
  • -1: object has z < 0.001 and is likely a star
  •  0: galaxy is not within 1,000 km/s of an absorber
  •  1: galaxy is within 1,000 km/s of an absorber but is not the closest galaxy
  •  2: galaxy is closest in this Table to an absorber, but a closer galaxy is known from SDSS or other sources
  •  3: closest known galaxy to an absorber
