MOJAVE XIV. AGN jet shapes & opening angles
We present 15 GHz stacked VLBA images of 373 jets associated with active galactic nuclei (AGN) having at least 5 observing epochs within a 20yr time interval 1994-2015 from the... -
Sou323 ICRF reference sample
We aim to evaluate the possibility of improving the International Celestial Reference System realization starting from the ICRF2 catalogue by investigating the coordinate time... -
1.3mm VLBI detections of M87
Approximately 10% of active galactic nuclei exhibit relativistic jets, which are powered by the accretion of matter onto supermassive black holes. Although the measured width... -
MOJAVE XXI Polarization variability in AGN jets
Using stacking of images obtained at different epochs, we studied the variability properties of linear polarization of active galactic nucleus (AGN) jets on parsec-scales. Our... -
MOJAVE. Persistent polarization in AGN jets
We analysed the parsec-scale linear polarization properties of 436 active galactic nuclei (AGN) based on 15GHz polarimetric Very Long Baseline Array (VLBA) observations. We... -
Scattering Properties of the Milky Way
We used archival very long baseline interferometry (VLBI) data of active galactic nuclei (AGN) observed from 1.4GHz to 86GHz to measure the angular size of VLBI radio cores in... -
Nearby young moving groups with machine learning
Nearby young stellar moving groups have been identified by many research groups with different methods and criteria, giving rise to caution regarding the reality of some groups.... -
Angular sizes of AGN cores at 2-43GHz
We have measured the angular sizes of radio cores of active galactic nuclei (AGN) and analyzed their sky distributions and frequency dependencies to study synchrotron opacity in... -
Fermi unassociated sources ATCA observations
We report results of the first phase of observations with Australia Telescope Compact Array (ATCA) at 5 and 9GHz of the fields around 411 {gamma}-ray sources with declinations... -
The epoch ICRF
The epoch International Celestial Reference Frame (epoch ICRF) is proposed as a new concept in order to consider the effect of apparent proper motion of the position of a radio... -
The EVN Galactic Plane Survey - EGaPS
I present a catalogue of positions and correlated flux densities of 109 compact extragalactic radio sources in the Galactic plane determined from analysis of a 48 hour VLBI... -
VLBI observations of NRAO 530 at 22, 43 and 86GHz
NRAO 530 is an optically violent variable source and has been studied with multi-epoch multifrequency high-resolution very long baseline interferometry (VLBI) observations. NRAO... -
LBA Calibrator Survey (LCS1)
We present a catalogue of accurate positions and correlated flux densities for 410 flat-spectrum, compact extragalactic radio sources previously detected in the AT20G survey.... -
VLBI Position Measurements
A large number (~2 million) of VLBI observations have been reduced in order to re ne the measured coordinates of the observed radio sources. The data reduction was carried out... -
First Caltech-Jodrell Bank VLBI Survey. II.
We report lambda-18 cm VLBI observations made in 1991 September of a further 25 objects from the first Caltech-Jodrell Bank VLBI Survey (the CJ1 survey). The CJ1 sample is a... -
First Caltech-Jodrell Bank VLBI Survey. I.
We present the first results from the first Caltech-Jodrell Bank VLBI survey (the CJ1 survey). The CJ1 sample includes 135 radio sources with total flux density... -
VLBI Ecliptic Plane Survey: VEPS-1
We present here the results of the first part of the VLBI Ecliptic Plane Survey (VEPS) program. The goal of the program is to find all compact sources within 7.5{deg} of the... -
Second Caltech-Jodrell Bank VLBI Survey. II.
This is the second of two papers presenting the Second Caltech- Jodrell Bank VLBI survey (CJ2). The CJ2 sample consists of 193 flat- and gigahertz-peaked-spectrum sources... -
Revisited jet bending in {gamma}-ray AGNs
We investigate the hypothesis that {gamma}-ray-quiet active galactic nuclei (AGNs) have a greater tendency for jet bending than {gamma}-ray-loud AGNs, revisiting the analysis of... -
VBLA observations of W51 Main/South
We report measurement of the trigonometric parallax of W51 Main/South using the Very Long Baseline Array. We measure a value of 0.185+/-0.010mas corresponding to a distance of...
