EVN observations of eleven GHz-Peaked-Spectrum radio sources at 2.3/8.4GHz
L. Xiang, D. Dallacasa, P. Cassaro +2
We present results of EVN observations of eleven GHz-Peaked-Spectrum (GPS) radio sources at 2.3/8.4 GHz. These sources are from the classical ''bright'' GPS source samples with pea…
The simultaneous VLA observations of Sgr A* from 90 to 0.7 cm
T. An, J. -H. Zhao, X. -Y. Hong +4
We present a spectrum of Sgr A* observed simultaneously on June 17, 2003 at wavelengths from 90 to 0.7 cm with the VLA. In the spectrum, we also include the measurements of Sgr A*…
Multi-Frequency VLBI Observations of GHz-Peaked Spectrum Sources
S. Kameno, M. Inoue, Z. -Q. Shen +2
We report results of pentachromatic VLBI survey for 18 GHz-peaked spectrum sources. Spectral fitting at every pixel across five frequencies allows us to illustrate distribution of…
Tracking the curved jet in PKS 1502+106
T. An, X. Y. Hong, T. Venturi +2
We carried out a multifrequency and multiepoch study of the highly polarized quasar, PKS 1502+106 at radio frequencies. The analysis is based on an EVN dataset at 5 GHz, archive VL…
Evn, Merlin, and Vla Observations of Nrao530
X. Y. Hong, J. H. Zhao, T. An +4
We present images of NRAO530 observed with the EVN (VLBI) at 5 GHz, the MERLIN at 1 .6 and 5 GHz, and the VLA at 5 and 8 GHz showing the complex morphology on scales from pc to kpc…
Galactic metallicity distribution from open clusters
L. Chen, J. L. Hou, J. J. Wang
We have compiled two new Galactic open cluster catalogues. The first one has 119 objects with age, distance and metallicity data, while the second one has 144 objects with both abs…
