The XXL Survey: I. Scientific motivations - XMM-Newton observing plan - Follow-up observations and simulation programme
M. Pierre, F. Pacaud, C. Adami +89
We present the XXL Survey, the largest XMM programme totaling some 6.9 Ms to date and involving an international consortium of roughly 100 members. The XXL Survey covers two extrag…
LOFAR MSSS: Detection of a low-frequency radio transient in 400 hrs of monitoring of the North Celestial Pole
A. J. Stewart, R. P. Fender, J. W. Broderick +99
We present the results of a four-month campaign searching for low-frequency radio transients near the North Celestial Pole with the Low-Frequency Array (LOFAR), as part of the Mult…
Wide-field LOFAR imaging of the field around the double-double radio galaxy B1834+620: A fresh view on a restarted AGN and doubeltjes
E. Orrú, S. van Velzen, R. F. Pizzo +8
The existence of double-double radio galaxies (DDRGs) is evidence for recurrent jet activity in AGN, as expected from standard accretion models. A detailed study of these rare sour…
On sky characterization of the BAORadio wide band digital backend: Search for HI emission in Abell85, Abell1205 and Abell2440 galaxy clusters
R. Ansari, J. E Campagne, P. Colom +5
We have observed regions of three galaxy clusters at z [0.06, 0.09] (Abell85, Abell1205, Abell2440), as well as calibration sources with the Nancay radiotelescope (NRT) to se…
