VIII/43 Radio survey of clusters of galaxies (Andernach+ 1978) ============================================================================ A radio survey of clusters of galaxies I. 11.1 cm observations of A 591, A 754, A 1066, A 1314, A 1517, A 2094, A 2142, A 2255, A 2256, A 2319 and A 2462. Haslam C.G.T., Kronberg P.P., Waldthausen H., Wielebinski R., Schallwich D.=1978A&AS...31...99H (Paper 1) Abstract As a part of a programme of studies of clusters of galaxies at centimeter wavelengths, we have observed eleven Abell clusters at 11.1cm using the 100 m radio telescope. The angular resolution at this wavelength is 4.6 arcmin, and an r.m.s. noise limit of 5 mK was reached in most of the observations. This enables us to investigate the distribution of low level emission near point sources in the clusters. ------------------------------------------------------------------------------ II. 11.1 cm observations of A 85, A 407, A 514, A 568, A 602, A 1361, A 1775, A 2036, A 2079, A 2224, A 2241, A 2365 and A 2634. Waldthausen H., Haslam C.G.T., Wielebinski R., Kronberg P.P. =1979A&AS...36..237W (Paper 2) Abstract As part of a programme of high-frequency observations of clusters of galaxies we have mapped thirteen Abell clusters at 2695 MHz (11.1cm wavelength) using the 100-m radio telescope. The angular resolution at this wavelength is 4.4 arcmin, and a rms noise level of 5 mJy per beam area was reached in most of the observations. These levels are comparable to the confusion limit of the telescope and enable us to investigate the distribution of complex low-level emission near point sources in the clusters. ------------------------------------------------------------------------------ III. 6.2 cm observations, radio spectra and optical identifications of sources in 29 Abell clusters. Andernach H., Waldthausen H., Wielebinski R. =1980A&AS...41..339A (Paper 3) Abstract As part of a program of high-frequency observations of clusters of galaxies we mapped twenty-nine Abell clusters of galaxies at 4850 MHz (6.2cm) using the 100-m radio telescope. The angular resolution at this wavelength is 2.6 arcmin, and r.m.s. noise levels of between 0.6 and 7 mJy per beam area were achieved. The radio maps were superimposed onto the optical fields of the Palomar Observatory Sky Survey red (E) prints. This revealed a large fraction of empty fields or optical objects significantly separated from the radio peak. Radio spectra of most of the detected sources were obtained by combining our published flux data with those at lower frequencies. We find a trend for cluster source spectra to become steeper with decreasing distance from the cluster centre. In a few cases there is an indication of low-level extended cluster emission. For A2319 the radio halo is clearly detected at 4850 MHz. ------------------------------------------------------------------------------ IV. 11.1 cm observations of 19 Abell clusters in total intensity and polarization. Andernach H., Schallwich D., Haslam C.G.T., Wielebinski R. =1981A&AS...43..155A (Paper 4) Abstract Radio continuum maps obtained with the Effelsberg 100-m telescope are presented for twelve rich clusters of galaxies. For some of these sources linear polarization information is given as well. Radio spectra of the sources were obtained using published flux values while optical identifications are suggested from overlays of radio maps onto the red prints of the Palomar Sky Survey. No radio haloes on the order of the cluster size have been detected in the presented sample. Observations of further seven cluster fields already published in paper II have been reanalyzed in linear polarization. ------------------------------------------------------------------------------ V. 11.1 cm maps of 18 Abell Clusters and observations of selected sources at 6.3 and 2.8 cm. Andernach H., Sievers A., Kus A., Schnaubelt J. =1986A&AS...65..561A (Paper 5) Abstract Thirteen areas containing eighteen rich clusters of galaxies have been mapped in radio continuum at 11.1 cm wavelength with the 100-m Effelsberg telescope. The angular resolution is 4.4 arcmin. Linear polarization was also recorded for some of the fields, which in most cases extend to the full Abell radius of the clusters. A few of the more complex sources in these fields have been additionally observed at 6.3 cm wavelength and, for the first time in this series of papers, also at 2.8 cm wavelength to study their structure and spectral variations. A total of 142 sources are reported here and radio spectra for 108 of them have been obtained using literature data. Optical identifications are proposed for nearly half of the detected sources. The mean spectral index of sources out to a projected source distance of about 0.8 Abell radii from the cluster centres exceeds the average value of all sources in the present survey and does not show a pronounced maximum near the cluster centres. There is a significant steepening of the spectra with decreasing 11.1 cm source flux density, regardless of projected distance to the cluster centre. ------------------------------------------------------------------------------ VI. More observations of 34 Abell cluster areas at 11.1, 6.3 and 2.8 cm and a preliminary statistical review of data in papers I-VI. Andernach H., Han Tie, Sievers A., Reuter H.-P., Junkes N., Wielebinski R. =1988A&AS...73..265A (Paper 6) Abstract Radio continuum maps of 26 Abell clusters of galaxies obtained with the Effelsberg 100-m telescope at a wavelength of 11.1cm (HPBW=4.4 arcmin) are presented. Most of the maps cover the full Abell radius of 3 Mpc (H_0_=50 km/s Mpc) of the clusters and contain linear polarization information. Selected cluster areas have also been mapped at a higher frequency and angular resolution: six fields at wavelength 6.3cm (HPBW=2.5 arcmin) and fourteen fields at wavelength 2.8cm (HPBW=1.2 arcmin). Radio data for 175 individual sources are listed and radio spectra for 141 of them have been obtained using literature data. Only very few of these show spectral steepening at high frequencies. This also holds for the local spectra of those radio galaxy tails which could be resolved with the Effelsberg antenna beam. Instead, the tail spectra steepen only with distance down the tail. Except for some indication in A665 and A2152 no more examples of radio halo sources were found at 2.7 GHz. Optical identifications for 35 of the detected sources are proposed on the basis of overlays with Palomar or ESO sky surveys. The IRAS point source catalogue has been searched for galaxy counterparts on the overlays and a total of 27 IRAS galaxies were found, of which 8 are new identifications. A statistical analysis of the entire survey data shows that for sources selected at 2.7 GHz the correlation between spectral index and projected cluster centre distance is weaker than for low frequency source samples. A strong trend for the spectra to steepen with decreasing flux density is evident. A large fraction of the empty field sources are found to have steep radio spectra and might constitute a "relic" population of cluster sources. ------------------------------------------------------------------------------ VII. 11.1 cm maps of 20 Abell clusters 6.3 cm maps of selected fields. Reuter H.-P., Andernach H. =1990A&AS...82..279R (Paper 7) Abstract Radio continuum maps of 20 Abell clusters of galaxies obtained with the 100-m Effelsberg telescope at 11.1 cm and maps of selected sources at 6.3 cm are presented. All observations contain linear polarization information, and most of the 11-cm maps cover the full Abell radius of 3 Mpc (H(0) = 50 km/s Mpc) of the clusters. Radio data for 86 sources are listed. Radio spectra were obtained for 56 sources using literature data. No evidence is found for the sources selected from a low frequency (151 MHz) survey to have systematically steeper radio spectra than the average of the entire Effelsberg cluster sample. Optical identifications are proposed for 40 sources. New identifications of two IRAS sources were found. Indirect evidence is presented for the presence of cluster radio halos in A948, A1329, A2176 and A2312. Author's Abstract : Radio continuum maps of 20 Abell clusters of galaxies obtained with the 100-m Effelsberg telescope at at a wavelength of 11.1 cm (HPBW=4.4 arcmin), and maps of selected sources at 6.3 cm are presented. All observations contain linear polarization information, and most of the 11-cm maps cover the full Abell radius of 3 Mpc (H(0) = 50 km/s Mpc) of the clusters. We list radio data for 86 sources, 25 of them (=29\%) are new detections. Radio spectra were obtained for 56 sources using literature data. No evidence is found for the sources selected from a low frequency (151 MHz) survey to have systematically steeper radio spectra than the average of the entire Effelsberg cluster sample. Optical identifications using POSS or ESO prints are proposed for 40 sources (=48\%), 27 of them are new identifications. Two new identifications of IRAS sources were found. We find some indirect evidence for the presence of cluster radio halos in A948, A1329, A2176 and A2312. ================================================================================ ADC_Keywords: Clusters, galaxy ; Radio sources ; Spectroscopy ; Redshifts ; References ; Morphology Keywords: clusters of galaxies - continuum maps - spectral index - radio spectra - linear polarization - radio sources - spectra of radio sources - optical and IR identification of radio sources Description: Observations of Abell clusters at 11.1, 6.2, 6.3 and 2.8cm with the 100m Effelsberg telescope.
