What is the primary beam response of an interferometer with unequal elements?

R. G. Strom

The EVN stations encompass elements with a range of diameters, even including an interferometer (the Westerbork Telescope, with up to 14 elements used together as a tied array). In…

Evidence for a hot dust-free inner disk around 51 Oph

W. -F. Thi, B. van Dalen, A. Bik +1

We report on the observation of CO bandhead emission around 51 Oph (dv=2). A high resolving power (R~10,000) spectrum was obtained with the infrared spectrometer ISAAC mounted on V…

Was the Narrow Line Seyfert 1 RGB J0044+193 ever radio loud?

T. J. Maccarone, J. C. A. Miller-Jones, R. P. Fender +1

We show new radio data and a re-analysis of old data for the Narrow Line Seyfert 1 (NLSy1) galaxy RGB J0044+193. This galaxy has previously been suggested to be both radio loud, an…

Flow of wet granular materials

N. Huang, G. Ovarlez, F. Bertrand +3

The transition from frictional to lubricated flow of a dense suspension of non-Brownian particles is studied. The pertinent parameter characterizing this transition is the Leighton…

Investigating the EGRET-radio galaxies link with INTEGRAL: the case of 3EG J1621+8203 and NGC 6251

L. Foschini, M. Chiaberge, P. Grandi +10

The analysis of an INTEGRAL AO2 observation of the error contours of the EGRET source 3EG J1621+8203 is presented. The only source found inside the error contours for energies betw…
