Serendipitous Detection of HI Absorption Sets the True Redshift of 4C +15.05 to
Kristen M. Jones, Tapasi Ghosh, Chris J. Salter
4C+15.05, (also known as NRAO 91, PKS 0202+14 or J0204+15), is a quintessential blazar. It has a luminous, variable radio spectrum, a super-luminal jet, and gamma-ray detections. A…
HI 21cm emission from the sub-damped Lyman-alpha absorber at z=0.0063 towards PG1216+069
Jayaram N. Chengalur, T. Ghosh, C. J. Salter +4
We present HI 21cm emission observations of the z ~ 0.00632 sub-damped Lyman-alpha absorber (sub-DLA) towards PG1216+069 made using the Arecibo Telescope and the Very Large Array (…
Radio polarimetry of compact steep spectrum sources at sub-arcsecond resolution
F. Mantovani, A. Rossetti, W. Junor +2
Aims - We report new Very Large Array polarimetric observations of Compact Steep-Spectrum (CSS) sources at 8.4, 15, and 23GHz. Methods - Using multi-frequency VLA observations we h…
Search for cold gas in z>2 damped Lyman-alpha systems: 21-cm and H_2 absorption
R. Srianand, N. Gupta, P. Petitjean +4
(Abridged) We present the results of a systematic GBT and GMRT survey for 21-cm absorption in a sample of 10 DLAs at 2<z_abs<3.4. Analysis of L-band VLBA images of the background Q…
Radio Polarimetry of 3C119, 3C318, and 3C343 at milliarcsecond resolution
F. Mantovani, A. Rossetti, W. Junor +2
We report VLBA polarimetric observations of the CSS sources 3C119, 3C318, and 3C343 at 5 and 8.4 GHz. The CSS source 3C119 has source rest-frame RM values up to ~10200 rad/m**2 in…
VLBA polarimetric observations of the CSS quasar 3C147
A. Rossetti, F. Mantovani, D. Dallacasa +3
Aims. We report new VLBA polarimetric observations of the compact steep-spectrum (CSS) quasar 3C147 (B0538+498) at 5 and 8.4GHz. Methods. By using multifrequency VLBA observations,…
