It has been known for nearly three decades that high-redshift radio galaxies exhibit steep radio spectra, and hence ultrasteep spectrum radio sources provide candidates for...

The dynamical evolution and radiative properties of luminous radio galaxies and quasars of the FR II type, are well understood. As a result, through the use of detailed modeling...

We have identified and studied a sample of 151 FR IIs found in brightest cluster galaxies (BCGs) in the MaxBCG cluster catalog with data from FIRST and NVSS. We have compared...

Super star clusters--extremely massive clusters found predominately in starburst environments--are essential building blocks in the formation of galaxies and thought to dominate...

We report on 1.4GHZ continuum observations for 11 VLA fields, using the D-configuration, which contain the A group of the Cancer Cluster. Sixteen Zwicky spiral galaxies in the...

We have used the VLA to survey the fields of the three clusters of galaxies; 0016+16, Abell 665 (0826+66) and Abell 2218 (1635+66) at 1440 MHz, 4860 MHz, and 14940 MHz (for the...

The question as to whether the distribution of radio loudness in active galactic nuclei (AGNs) is actually bimodal has been discussed extensively in the literature. Furthermore,...

As a step toward investigating the parsec-scale properties of faint extragalactic radio sources, the Very Long Baseline Array (VLBA) was used at 5.0GHz to obtain...

We present the results from two deep radio integrations at 8.4 GHz using the Very Large Array. One of the fields, at 13h, +43{deg} (SA 13 field), has an rms noise level of...

This catalog contains a survey of a rectangular area of 10x6 degrees in galactic coordinates (95.5{deg} < l < 101.5{deg} ; 28{deg} < b < 38{deg}) in the radio...

This catalog contains a survey at 327 MHz of the A262 cluster region. The survey was performed with the WSRT Telescope in the redundancy mode, and covers a circular region of 21...

The radio continuum radiation at 1415MHz of 450 galaxies was observed with the Westerbork Synthesis Radio Telescope. 190 galaxies were detected. The survey provides data on the...

This is the second paper based on the 408MHz monitoring program with the East-West arm of the Bologna interferometer. The monitoring concerned 125 radio sources measured...

We present 1300{mu}m continuum observations and measurements of the CO (1-0) and (2-1) emission from the inner regions of 98 normal galaxies. The spatial resolution ranges from...

We present observations of the ^12^CO(J=1-0) line at 2.6mm of 65 galaxies located in the Coma supercluster region: 33 actually belong to the Coma supercluster while 32 are...

In this paper we present short H I synthesis observations of 57 galaxies without H I information in the RC3. These are a by-product of a large survey with the WSRT of the...

A large survey of galaxies in the J=1-0 CO line, performed during 1985-1988 using the 15-m SEST and the 20-m millimetre wave telescope of Onsala Space Observatory, is presented....

We have obtained short HI observations of 60 late type spiral galaxies with the Westerbork Synthesis Radio Telescope (WSRT). Several HI properties are presented, including the...

The evolution of active galactic nuclei (AGNs) is closely connected to their host galaxies and surroundings. Via feedback processes, AGNs can counteract the cooling of the...

X-shaped radio galaxies (XRGs) are characterised by two pairs of misaligned lobes: active lobes hosting radio jets and the wings. None of the formation mechanisms proposed thus...
