X-rays from the jet in 3C 273: clues from the radio-optical spectra
S. Jester, H. -J. Roeser, K. Meisenheimer +1
Using new deep VLA and HST observations of the large-scale jet in 3C273 matched to 0.3" resolution, we have detected excess near-ultraviolet emission (300 nm) above a synchrotron c…
Space VLBI at Low Frequencies
D. Jones, R. Allen, J. Basart +25
At sufficiently low frequencies, no ground-based radio array will be able to produce high resolution images while looking through the ionosphere. A space-based array will be needed…
The radio-ultraviolet spectral energy distribution of the jet in 3C273
S. Jester, H. -J. Roeser, K. Meisenheimer +1
We present deep VLA and HST observations of the large-scale jet in 3C 273 matched to 0.3" resolution. The observed spectra show a significant flattening in the infrared-ultraviolet…
Origin of the ring structures in Hercules A -- Sub-arcsecond 144 MHz to 7 GHz observations
R. Timmerman, R. J. van Weeren, J. R. Callingham +18
The prominent radio source Hercules A features complex structures in its radio lobes. Although it is one of the most comprehensively studied sources in the radio sky, the origin of…
Observations of a nearby filament of galaxy clusters with the Sardinia Radio Telescope
V. Vacca, M. Murgia, F. Govoni +29
We report the detection of diffuse radio emission which might be connected to a large-scale filament of the cosmic web covering a 8deg x 8deg area in the sky, likely associated wit…
The Deep Full-Stokes Radio Sky
A. R. Taylor, S. Bhatnagar, J. Condon +8
The new broad-band capabilities of large radio interferometers such as the GMRT and JVLA allow for long-integration mosaic imaging observations to create ultra-deep full-polarizati…
