Radio observations of the cool gas, dust, and star formation in the first galaxies
C. Carilli, F. Walter, R. Wang +6
We summarize cm through submm observations of the host galaxies of z ~ 6 quasars. These observations reveal the cool molecular gas (the fuel for star formation), the warm dust (hea…

NIR spectroscopy of SDSS J0303-0019: a low luminosity, high Eddington ratio quasar at z~6
J. D. Kurk, F. Walter, X. Fan +4
We present sensitive near--infrared VLT ISAAC spectroscopic observations of the z=6.08 quasar SDSS J030331.40-001912.9. This QSO is more than a magnitude fainter than other QSOs at…
