We present optical and infrared broad-band images, radio maps, and optical spectroscopy for the nuclear region of a sample of nearby galaxies. The galaxies have been drawn from...

With the goal of identifying high-redshift radio galaxies with Fanaroff-Riley class I (FR I) classification, here are presented high-resolution, wide-field radio observations,...

We present new continuum VLA observations of the nearby Sy 1.5 galaxy NGC 5033, made at 4.9- and 8.4-GHz on 2003 April 8. Combined with VLA archival observations at 1.4- and...

By combining the REFLEX and NORAS cluster data sets with the NVSS radio catalogue, we obtain a sample of 145, z<0.3, X-ray-selected clusters brighter than...

We present basic observational data on the 6C** sample. This is a new sample of radio sources drawn from the 151-MHz 6C survey, which was filtered with radio criteria chosen to...

We present the first paper in a series detailing the results of ^13^CO observations of a ~1{deg}^2^ region of the giant molecular cloud (GMC) complex associated with the HII...

18 days of MERLIN data and 42h of A-array VLA data at 1.4GHz have been combined to image a 10-arcmin field centred on the Hubble Deep Field (HDF). This area also includes the...

We have observed the cosmic microwave background (CMB) temperature fluctuations in eight fields covering three separated areas of sky with the Very Small Array at 34GHz. A total...

We discuss the radio, optical, and X-ray properties of two newly discovered, very X-ray luminous, distant clusters of galaxies. Both systems were noted as cluster candidates in...

We have analysed radio-continuum mosaics of the Small Magellanic Cloud (SMC) obtained using both the Australia Telescope Compact Array (ATCA) and the Parkes telescope and...

We have observed two fields - Field I (l=3.2{deg}, b=1.0{deg}) and Field II (l=356.8{deg}, b=-0.1{deg}) - with the Giant Metrewave Radio Telescope (GMRT) at 330MHz. In the first...

The Cambridge Low-Frequency Synthesis Telescope has been used to produce a representative sample of low-frequency variable sources. 20 fields, each covering an area of...

Variability in 408MHz flux density, over a 1yr interval between 1995 and 1996, has been investigated using the DRAO Synthesis Telescope for a complete sample of 322 sources with...

We have imaged the portion of the Shapley Concentration core surrounding the cluster A3556 at wavelengths of 36cm with the Molonglo Observatory Synthesis Telescope (MOST), and...

We present a catalogue of 233 BL Lacertae objects compiled through an extensive bibliographic search updated to mid-1995. A large fraction of the sources listed in the catalogue...

The Cambridge Low Frequency Synthesis Telescope has been used to survey a region ~7x7deg^2^ about the North Ecliptic Cap at 151MHz with a resolution of 70x77arcsec^2^. The...

We present results from radio continuum observations of two fields made at 408 and 1420MHz with the DRAO Synthesis Telescope. Two sets of data, one year apart, were obtained of...

The completeness of the Arecibo 1612 MHz survey of color-selected/IRAS sources (see references) is extended to (25-12){mu}m>-0.7. In addition (1) most IR sources with...

A 29.3deg^2 region surrounding the north ecliptic pole (NEP; R.A.=18h00m, Dec.=+66d30m) was mapped with the Very Large Array at 1.5GHz to support the deepest portion of the...

Radio continuum observations were made of 59 IRAS sources that have 100{mu}m flux densities >=1000Jy and far-infrared colors identified with ultracompact (UC) HII regions....
