A sample of radio-loud QSOs at redshift ~ 4
J. Holt, C. R. Benn, M. Vigotti +5
We obtained spectra of 60 red, starlike objects (E< 18.8) identified with FIRST radio sources, S_{1.4GHz} > 1 mJy. Eight are QSOs with redshift z> 3.6.Combined with our pilot searc…
On the origin of the X-ray emission from a narrow-line radioquasar at z>1
X. Barcons, R. Carballo, F. J. Carrera +5
We present new XMM-Newton X-ray observations of the z=1.246 narrow-line radioquasar RX J1011.2+5545 serendipitously discovered by ROSAT. The flat X-ray spectrum previously measured…
Tomography of high-redshift clusters with OSIRIS
A. Fernandez-Soto, J. Bland-Hawthorn, J. I. Gonzalez-Serrano +1
High-redshift clusters of galaxies are amongst the largest cosmic structures. Their properties and evolution are key ingredients to our understanding of cosmology: to study the gro…
