The GLObal view of the STAR formation in the Milky Way (GLOSTAR) survey studies star formation with the Very Large Array (VLA) and the Effelsberg 100 meter radio telescope in...

Studies of Galactic HII regions are of crucial importance for studying star formation and the evolution of the interstellar medium. Gaining an insight into their physical...

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...

We present the second catalogue of accurate positions and correlated flux densities for 1100 compact extragalactic radio sources that were not observed before 2008 at high...

We present an overview and the first results from a large-scale pulsar timing programme that is part of the UTMOST project at the refurbished Molonglo Observatory Synthesis...

In this paper we present the first speckle interferometric measurements of binary stars performed at the Observatorio do Pico dos Dias of the Laboratorio Nacional de Astrofisica...

We present the first dedicated observations of Interplanetary Scintillation (IPS) with the Murchison Widefield Array. We have developed a synthesis imaging technique, tailored...

In the next few years the classification of radio sources observed by the large surveys will be a challenging problem and spectral index is a powerful tool for addressing it....

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...

We have cross matched the Gaia Data Release 1 secondary data set that contains positions of 1.14 billion objects against the most complete to date catalogue of very long...

An IVOA-defined metadata table for radio measurements, with extra metadata for interferometric measurements ("visibilities") as well as single-dish observations. You will almost...

We report on full-Stokes L-band observations of 98 MeerKAT calibration sources. Linear polarization is detected in 71 objects above a fractional level of 0.2%. We identify ten...

Over the past few years, chemical studies have revealed multiple structures in the vicinity of young stellar objects (YSOs). It has become evident that specific physical...

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...

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...
