Infrared Properties of Serendipitous X-ray Quasars
نویسندگان
چکیده
Near-infrared measurements have been obtained of 30 quasars originally found serendipitously as x-ray sources in fields of other objects. The observations show that the infrared characteristics of these quasars do not differ significantly from those of quasars selected by other criteria. Because this x-ray-selected sample is subject to different selection biases than previous radio and optical surveys, this conclusion is useful in validating previous inferences regarding the infrared colors of “typical” quasars.

New X-ray quasars behind the Small Magellanic Cloud
We present five X-ray quasars behind the Small Magellanic Cloud, increasing the number of known quasars behind the SMC by ∼40%. They were identified via follow-up spectroscopy of serendipitous sources from the Chandra X-ray Observatory matched with objects from the OGLE database. All quasars lie behind dense parts of the SMC, and could be very useful for proper motion studies. We analyze X-ray ...
متن کاملInfrared observations of serendipitous hard Chandra X - ray sources
We present observations of a sample of optically-faint, hard X-ray sources of the kind likely to be responsible for much of the hard X-ray background. We confirm that such sources are easily detected in the near-infrared, and find that they have a featureless continuum suggesting that the active nucleus is heavily obscured. The infrared colours of the majority of the targets observed are consis...
متن کاملPowerful obscured AGN among X-ray hard, optically-dim serendipitous Chandra sources
We present a small sample of ̧X-ray sources selected from the fields of ACIS observations which probe fluxes around the break in the hard band source counts. The targets of these fields include 9 nearby galaxy clusters, 1 distant cluster and 2 powerful radio galaxy fields. The follow-up of this serendipitous sample was biased towards X-ray hard and optically-dim sources mostly not seen on the D...
متن کاملMulti - wavelength observations of serendipitous Chandra X - ray sources in the field of A 2390
We present optical spectra and near-infrared imaging of a sample of serendipitous X-ray sources detected in the field of Chandra observations of the A 2390 cluster of galaxies. The sources have 0.5-7 keV fluxes of 0.6 − 8 × 10 −14 erg cm −2 s −1 and lie around the break in the 2-10 keV source counts. They therefore are typical of sources dominating the X-ray Background in that band. Twelve of t...
متن کاملRadio through X-ray Spectral Energy Distributions of 38 Broad Absorption Line Quasars
We have compiled the largest sample of multiwavelength spectral energy distributions (SEDs) of Broad Absorption Line (BAL) quasars to date, from the radio to the X-ray. We present new Spitzer MIPS (24, 70, and 160μm) observations of 38 BAL quasars in addition to data from the literature and public archives. In general, the mid-infrared properties of BAL quasars are consistent with those of non-...
