The extended High A(V) Quasar Survey: Searching for dusty absorbers toward mid-infrared selected quasars
J. -K. Krogager, J. P. U. Fynbo, K. E. Heintz +6
We present the results of a new spectroscopic survey for dusty intervening absorption systems, particularly damped Ly absorbers (DLAs), towards reddened quasars. The candidate q…
Determining the fraction of reddened quasars in COSMOS with multiple selection techniques from X-ray to radio wavelengths
K. E. Heintz, J. P. U. Fynbo, P. Møller +8
The sub-population of quasars reddened by intrinsic or intervening clouds of dust are known to be underrepresented in optical quasar surveys. By defining a complete parent sample o…
Serendipitous discovery of a projected pair of QSOs separated by 4.5 arcsec on the sky
K. E. Heintz, J. P. U. Fynbo, J. -K. Krogager +8
We present the serendipitous discovery of a projected pair of quasi-stellar objects (QSOs) with an angular separation of arcsec. The redshifts of the two QSOs are widely…
