A suspected Dark Lens revealed with the e-EVN
Z. Paragi, S. Frey, B. Campbell +1
The e-VLBI technique offers a unique opportunity for users to probe the milliarcsecond (mas) scale structure of unidentified radio sources, and organise quick follow-up observation…
Multiwavelength monitoring of the enigmatic Narrow-Line Seyfert 1 PMN J0948+0022 in March-July 2009
LAT Collaboration, E. Angelakis, C. Bailyn +39
Following the recent discovery of gamma rays from the radio-loud narrow-line Seyfert 1 galaxy PMN J0948+0022 (z=0.5846), we started a multiwavelength campaign from radio to gamma r…
Interferometric Observations of Algol
T. Borkovits, Sz. Csizmadia, Zs. Paragi +6
We determined the spatial orientation of the Algol AB close pair orbital plane using optical interferometry with the CHARA Array, and radio interferometry with the European VLBI Ne…
Interferometric Observations of the Hierarchical Triple System Algol
Sz. Csizmadia, T. Borkovits, Zs. Paragi +10
Algol is a triple stellar system consisting of a close semidetached binary orbited by a third object. Due to the disputed spatial orientation of the close pair, the third body pert…
Is an obscured AGN at the centre of the disk galaxy IC 2497 responsible for Hanny's Voorwerp?
H. Rampadarath, M. A. Garrett, T. Muxlow +3
We present the results of VLBI and MERLIN observations of the massive disk galaxy IC 2497. Optical observations of IC 2497 revealed the existence of a giant emission nebula "Hanny'…
Probing the behaviour of the X-ray binary Cygnus X-3 with very-long-baseline radio interferometry
V. Tudose, J. C. A. Miller-Jones, R. P. Fender +8
In order to test the recently proposed classification of the radio/X-ray states of the X-ray binary Cyg X-3, we present an analysis of the radio data available for the system at mu…
