Seven - frequency VLBI observations of the GHz - Peaked - Spectrum source OQ 208
We present images of quasi-simultaneous VLBI observations of the GHzPeaked-Spectrum radio source OQ 208 with the Very Long Baseline Array at 1.4, 1.7, 2.3, 5.0, 8.4, 15.4 GHz and the European VLBI Network at 6.7 GHz. The low frequency (1.4, 1.7 and 2.3 GHz) observations reveal a weak and extended steep-spectrum component at about 30 mas away in the position angle of −110 which may be a remnant ...
متن کاملVLBI observations of nineteen GHz-Peaked-Spectrum radio sources at 1.6 GHz
Abstract. Aims and Methods: We present the results of VLBI observations of nineteen GHz-Peaked-Spectrum (GPS) radio sources at 1.6 GHz. Of them, 15 sources are selected from the Parkes Half Jansky (PHJ) sample (Snellen 2002), 4 others are from our previous observation list. We aimed at imaging the structure of GPS sources, searching for Compact Symmetric Objects (CSOs) and studying the absorpti...
متن کاملEuropean VLBI Network observations of fourteen GHz - Peaked - Spectrum radio sources at 5 GHz
We present the results of EVN polarization observations of fourteen GHz-Peaked-Spectrum (GPS) radio sources at 5 GHz. These sources were selected from bright GPS source samples and we aimed at finding Compact Symmetric Objects (CSOs). We have obtained full polarization 5 GHz VLBI observations of 14 sources providing information on their source structure and spectral indices. The results show th...
متن کاملParsec-scale properties of GHz-Peaked Spectrum sources from 2.3 and 8.6 GHz VLBI surveys
We investigate the sample of 213 GPS sources selected from simultaneous multi-frequency 1– 22 GHz observations obtained with RATAN–600 radio telescope. We use publicly available data to characterize parsec-scale structure of the selected sources. Among them we found 121 core dominated sources, 76 Compact Symmetric Object (CSO) candidates (24 of them are highly probable), 16 sources have complex...
متن کامل23 Ghz Vlbi Observations of Sn 2008ax 23 Ghz Vlbi Observations of Sn 2008ax (research Note)
We report on phase-referenced 23 GHz Very-Long-Baseline-Interferometry (VLBI) observations of the type IIb supernova SN 2008ax, made with the Very Long Baseline Array (VLBA) on 2 April 2008 (33 days after explosion). These observations resulted in a marginal detection of the supernova. The total flux density recovered from our VLBI image is 0.8±0.3 mJy (one standard deviation). As it appears, t...
