Unveiling the Complex Jet Dynamics in the Blazar 2021+317 through Multi-Epoch VLBI Observations
Haitian Shang, Wei Zhao, Xiaoyu Hong +4
We present an investigation of the compact structure of the AGN 2021+317 based on multi-epoch Very Long Baseline Interferometry (VLBI) observations at 15, 22, and 43 GHz in the per…
The radio core and jet in the broad absorption line quasar PG 1700+518
J. Yang, F. Wu, Z. Paragi +1
The blue-shifted broad absorption lines (BAL) or troughs are observed in Active Galactic Nuclei (AGNs) when our line of sight is intercepted by a high speed outflow (wind), likely…
Radio structure of the blazar 1156+295 with sub-pc resolution
W. Zhao, X. -Y. Hong, T. An +4
1156+295 is a flat-spectrum quasar which is loud at radio and gamma-ray. Previous observations of the source revealed a radio morphology on pc to kpc scales consistent with a helic…
The Submillimeter Array 1.3 mm line survey of Arp 220
S. Martin, M. Krips, J. Martin-Pintado +7
We present the first aperture synthesis unbiased spectral line survey toward an extragalactic object. The survey covered the 40 GHz frequency range between 202 and 242 GHz of the 1…
Metal Enrichment via Ram Pressure Stripping in the IGM of the Compact Galaxy Group RGH 80
Haijuan Cui, Haiguang Xu, Junhua Gu +4
By creating and analyzing the two dimensional gas temperature and abundance maps of the RGH 80 compact galaxy group with the high-quality Chandra data, we detect a high-abundance (…
Kinematics of the parsec-scale radio jet in 3C48
T. An, X. Y. Hong, M. J. Hardcastle +6
We present results on the compact steep-spectrum quasar 3C 48 from observations with the VLBA, MERLIN and EVN at multiple radio frequencies. In the 1.5-GHz VLBI images, the radio j…
