Spurious source generation in mapping from noisy phase-self-calibrated data
I. Marti-Vidal, J. M. Marcaide
Phase self-calibration (or selfcal) is an algorithm often used in the calibration of interferometric observations in astronomy. Although a powerful tool, this algorithm presents st…
Absolute kinematics of radio source components in the complete S5 polar cap sample. III. First wide-field high-precision astrometry at 15.4 GHz
I. Marti-Vidal, J. M. Marcaide, J. C. Guirado +2
We report on the first wide-field, high-precision astrometric analysis of the 13 extragalactic radio sources of the complete S5 polar cap sample at 15.4 GHz. We describe new algori…
8.4GHz VLBI observations of SN2004et in NGC6946
I. Marti-Vidal, J. M. Marcaide, A. Alberdi +13
We report on 8.4GHz Very Long Baseline Interferometry (VLBI) observations of the type II-P supernova SN2004et in the spiral galaxy NGC 6946, made on 20 February 2005 (151 days afte…
15 years of VLBI observations of two compact radio sources in Messier 82
R. J. Beswick, J. D. Riley, I. Marti-Vidal +6
We present the results of a second epoch of 18cm global Very Long-Baseline Interferometry (VLBI) observations, taken on 23 February 2001, of the central kiloparsec of the nearby st…
On the dynamics of the ABDoradus system
J. C. Guirado, I. Marti-Vidal, J. M. Marcaide +8
We present an astrometric analysis of the binary systems ABDorA /ABDorC and ABDorBa / ABDorBb. These two systems of well-known late-type stars are gravitationally associated and th…
