Applying full polarization A-Projection to very wide field of view instruments: An imager for LOFAR
C. Tasse, B. van der Tol, J. van Zwieten +2
The aimed high sensitivities and large fields of view of the new generation of interferometers impose to reach high dynamic range of order 1: to 1: in the case of…
Probing the bias of radio sources at high redshift
Sean Passmoor, Catherine Cress, Andreas Faltenbacher +4
The relationship between the clustering of dark matter and that of luminous matter is often described using the bias parameter. Here, we provide a new method to probe the bias of i…
Sub-millimetre source identifications and the micro-Jansky source population at 8.4 GHz in the William Herschel Deep Field
I. Heywood, R. M. Bielby, M. D. Hill +4
[Abridged] Sub-mm observations of the William Herschel Deep Field using LABOCA revealed possible counterparts for 2 X-ray absorbed QSOs. The aim here is to exploit EVLA imaging at…
PKS 2123-463: a confirmed gamma-ray blazar at high redshift
F. D'Ammando, A. Rau, P. Schady +11
The flat spectrum radio quasar (FSRQ) PKS 2123-463 was associated in the First Fermi-LAT source catalog with the gamma-ray source 1FGL J2126.1-4603, but when considering the full f…
Discovery of New Faint Northern Galactic Planetary Nebulae
Agnes Acker, Henri M. J. Boffin, Nicolas Outters +4
We present the discovery of 6 nebular objects made by amateur astronomers. Four of these discoveries are clearly planetary nebulae (PNe), one is a possible PN, and another is a lik…
Faint Extended OH Emission from the Local Interstellar Medium in the Direction l \approx 108\circ, b \approx 5\circ
Ronald J. Allen, Mónica Ivette Rodríguez, John H. Black +1
We have mapped faint 1667 OH line emission (TA \approx 20 - 40 mK in our \approx 30' beam) along many lines of sight in the Galaxy covering an area of \approx 4\circ \times 4\circ…
