The most Distant [OIII]-emitting Quasar PKS 1937−101 at redshift 3.8

چکیده
We report the discovery of a high-z quasar with unambiguous [OIII]λ5007 emission; PKS 1937−101 at redshift 3.8. This quasar, however, shows little evidence for rest-frame ultraviolet and optical FeII emission. It is thus shown that PKS 1937−101 does not belong to a class of super iron-rich high-z quasars reported by Elston, Thompson, & Hill (1994). The epoch of major star formation in the host galaxy is discussed briefly. Subject headings: cosmology: observations galaxies: evolution galaxies: formation quasars: individual (PKS 1937−101) quasars: emission lines Visiting astronomer, Kitt Peak National Observatory, National Optical Astronomy Observatories, which are operated by the Association of Universities for Research in Astronomy, Inc., under contract with the National Science Foundation.

ASTRONOMY AND ASTROPHYSICS The first XMM-Newton spectrum of a high redshift quasar
Your thesaurus codes are: missing; you have not inserted them ASTRONOMY AND ASTROPHYSICS The first XMM-Newton spectrum of a high redshift quasar-PKS 0537−286. Abstract. We present XMM-Newton observations of the high redshift (z = 3.104), radio-loud quasar PKS 0537−286. The EPIC CCD cameras provide the highest signal-to-noise spectrum of a high-z quasar to date. The EPIC observations show that P...
متن کاملHi 21cm Absorption in Two Low Redshift Damped Lyα Systems
We report the discovery of two low redshift HI 21cm absorbers, one at z = 0.2212 towards the z em = 0.630 quasar OI 363 (B0738+313), and the other at z = 0.3127 towards PKS B1127-145 (z em = 1.187). Both were found during a survey of MgII selected systems at redshifts 0.2 < z < 1 using the new UHF-high system at the Westerbork Synthesis Radio Telescope (WSRT). New HST/FOS observations also iden...

The BL–Lac family of active galaxies possess almost featureless spectra and exhibit rapid variability over their entire spectral range. A number of models have been developed to explain these extreme properties, several of which have invoked the action of microlensing by sub–stellar mass objects in a foreground galaxy; this not only introduces variability, but also amplifies an otherwise normal...

We present new spectroscopic observations of the southern radio galaxy PKS154979 (z = 0.152). Despite the flat spectrum character of the radio emission from this source, our optical spectra show no sign of the broad permitted lines and non-stellar continuum characteristic of quasar nuclei and broad line radio galaxies. However, the high ionization forbidden lines, including [OIII]λλ5007,4959, a...
متن کاملThe highest redshift radio quasar as seen with the EVN and the VLA
Abstract. We report on European VLBI Network (EVN) and Very Large Array (VLA) observations of SDSS J0836+0054, the most distant radio-loud quasar known at present (z = 5.774). The source, with a total flux density of 1.1 mJy, shows a compact structure at ∼ 10 mas angular resolution at 1.6 GHz frequency, with no indication of multiple images produced by gravitational lensing within a 4′′ × 4′′ f...
