The catalogue contains compact radio sources with accurate positions observed with the Very Large Array (VLA). These sources are primarily intended for use as phase calibration...

Nearly 200 hours of observing with the Murchison Widefield Array (MWA) radio telescope during the Galactic and Extra-galactic All-sky MWA (GLEAM) survey were used to assemble...

The Australia Telescope Compact Array (ATCA) has been used in support of the VLBI Space Observatory Programme (VSOP) space VLBI mission, to monitor the total and polarised flux...

The VSOP mission is a Japanese-led project to image radio sources with sub-milliarcsec resolution by correlating the signal from the orbiting 8-m telescope, HALCA, with a global...

We present speckle interferometric measurements of binary stars performed during September and October of 2009 with the 2.1m telescope of the Observatorio Astronomico Nacional...

We present speckle interferometric measurements of binary stars performed during August of 2010 with the 1.5m telescope and during November of 2010 with the 2.1m telescope of...

We have measured the 2.3GHz total and correlated flux densities on a baseline of 275km of all sources in the Parkes catalogue which : (i) are south of declination +10deg, (ii)...

We present the results of speckle interferometric observations of 156 stars possessing global magnetic fields, carried out with the 6-m BTA telescope of the Special...

The results of speckle interferometric observations of 194 binary stars performed at the BTA 6m telescope in 2002-2006 are presented in this paper. For speckle observations we...

We present the results of speckle interferometry of a sample of 117 chemically peculiar stars with global magnetic fields. The observations were made in December 2009 at the BTA...

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...

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...

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...

Differential Interferometry allows to obtain the differential visibility and phase, in addition to the spectrum. The differential phase contains important information about the...

We present observations of a region of the Galactic plane taken during the Early Science Program of the Australian Square Kilometre Array Pathfinder (ASKAP). In this context, we...

We observed 51 sources in the Q-U-I JOint TEnerife (QUIJOTE) cosmological fields which were brighter than 1Jy at 30GHz in the Planck Point Source Catalogue (version 1), with the...

Modern radio telescopes are routinely reaching depths where normal star-forming galaxies are the dominant observed population. Realizing the potential of radio as a tracer of...

In this paper, we present the first multiband speckle interferometric measurements of binary stars performed using the 2.1m telescope of the Observatorio Astrofisico Guillermo...

A thorough study of radio emission in active galactic nuclei (AGNs) is of fundamental importance to understand the physical mechanisms responsible for the emission and the...

We present an ALMA study of the ~180 brightest sources in the SCUBA-2 850-{mu}m map of the COSMOS field from the S2COSMOS survey, as a pilot study for AS2COSMOS - a full survey...
