A new XMM-Newton observation of Pictor A radio lobes confirms the non-thermal origin of the X-ray emission
G. Migliori, P. Grandi, G. G. C. Palumbo +3
X-ray emission from the eastern radio lobe of the FRII Radio Galaxy Pictor A was serendipitously discovered by a short observation of XMM-Newton in 2001. The X-ray spectrum, accumu…
The VIMOS-VLT Deep Survey - The evolution of galaxy clustering per spectral type to z~1.5
B. Meneux, O. LeFevre, L. Guzzo +47
We measure the evolution of clustering for galaxies with different spectral types from 6495 galaxies with 17.5<=I_AB<=24 and measured spectroscopic redshift in the first epoch VIMO…
The hard X-ray view of Giga-Hertz Peaked Spectrum Radio Galaxies
M. Guainazzi, A. Siemiginowska, C. Stanghellini +3
We present the first broadband X-ray observations of four Giga-Hertz Peaked Spectrum (GPS) radio galaxies at redshift <~1 performed by Chandra and XMM-Newton. These observations mo…
Search for massive protostar candidates in the southern hemisphere: II. Dust continuum emission
Maria T. Beltran, Jan Brand, Riccardo Cesaroni +4
In an ongoing effort to identify and study high-mass protostellar candidates we have observed in various tracers a sample of 235 sources selected from the IRAS Point Source Catalog…
ESO Imaging Survey: Optical follow-up of 12 selected XMM-Newton fields
J. P. Dietrich, J. -M. Miralles, L. F. Olsen +12
(Abridged) This paper presents the data recently released for the XMM-Newton/WFI survey carried out as part of the ESO Imaging Survey (EIS) project. The aim of this survey is to pr…
Unobscured QSO2: A New Class of Objects?
A. Wolter, I. M. Gioia, J. P. Henry +1
We present in this paper optical and X-ray follow up observations for three X-ray selected objects extracted from the ROSAT North Ecliptic Pole survey which is a flux-limited, comp…
Signatures of restarted activity in core-dominated, triple radio sources selected from the FIRST survey
A. Marecki, P. Thomasson, K. -H. Mack +1
Signatures of the re-occurrence of activity in radio-loud AGNs, indicated either by the so-called double-double or X-shaped structures, have been observed in a number of radio sour…
The Warped Nuclear Disk of Radio Galaxy 3C 449
Grant R. Tremblay, Alice C. Quillen, David J. E. Floyd +11
Among radio galaxies containing nuclear dust disks, the bipolar jet axis is generally observed to be perpendicular to the disk major axis. The FR I radio source 3C 449 is an outlie…
A large population of galaxies 9 to 12 billion years back in the history of the Universe
O. Le Fevre, S. Paltani, S. Arnouts +6
To understand the evolution of galaxies, we need to know as accurately as possible how many galaxies were present in the Universe at different epochs. Galaxies in the young Univers…
