- Description:
- The Cambridge Low Frequency Synthesis Telescope has been used at 151 MHz to survey a region of 1393 square degrees, in the range RA 9h to 16h, Dec 20deg to 35deg, with an angular resolution of 108x108cosec(dec) arcsec^2^. The rms noise on the maps is in general ~35-55 mJy/beam but varies considerably and exceeds this in some areas. We have extracted sources with signal-to-noise ratio > 5.5, a total of 5526, and present a catalogue of their positions and flux densities.

- Description:
- The Cambridge Low Frequency Synthesis Telescope has been used at 151MHz to survey three regions centred at RA=10h05min, DE=53{deg}54', RA=10h42min, DE=57{deg}36' and RA=13h32min, DE=38{deg}10', each of area 7.3x7.3cosec(DE)deg^2^. The resolution is 70x70cosec(DE)arcsec^2^, and the rms noise on the maps is typically 15mJy/beam. We present positions and flux densities for 2381 sources which have signal-to-noise ratios >5.5.

- 20cm observations of deep Swire Field

- Description:
- We present results from deep radio observations taken with the Very Large Array at a center frequency of 1400MHz covering a region of the Spitzer Wide-area InfraRed Extragalactic Survey of the Spitzer Legacy survey, centered at 10:46:00, +59:01:00 (J2000). The reduction and cataloging of radio sources are described. An electronic catalog of the sources detected above 5{sigma} is also presented. The survey presented is the deepest so far in terms of the radio source density on the sky. Perhaps surprisingly, the sources down to the bottom of the catalog appear to have median angular sizes still greater than 1-arcsec, like their cousins 10-100 times stronger. The shape of the differential logN-logS counts also seems to require a correction for the finite sizes of the sources to be self-consistent. If the logN-logS normalization remains constant at the lowest flux densities, there are about six sources per square arcminute at 15uJy at 20cm. Given the finite-source size this implies that we may reach the natural confusion limit near 1uJy.

- Description:
- We present one of the deepest radio continuum surveys to date at a wavelength >~1m. The observations were taken with the VLA at 324.5MHz covering a region of the SWIRE Spitzer Legacy survey, centered at 10:46:00, +59:01:00 (J2000). The data reduction and analysis are described and an electronic catalog of the sources detected above 5{sigma} is presented. We also discuss the observed angular size distribution for the sample. Using our deeper 20cm survey of the same field, we calculate spectral indices for sources detected in both surveys.

- Description:
- The 21 cm Galactic Plane survey was carried out with the Effelsberg 100-m radio telescope (HPBW = 9.4'). It contains sources from l=357{deg} to l=95.5{deg} and from -4{deg}<b<4{deg}. The data were absolutely calibrated by using the Stockert Northern Sky survey at the same wavelength. Included are 884 compact objects with peak flux densities greater than 98 mJy (or 200 mK Tb) and apparent sizes less than 16'. This survey is especially useful for studying extended emission complexes in the Galactic plane and complements the Effelsberg 11 cm survey of the Galactic plane (Reich et al., Cat. <J/A+AS/85/805>)

- Description:
- We analysed the 21cm Galactic Plane survey carried out with the Effelsberg 100-m telescope for small diameter sources. We present a list of 1830 radio sources with a maximum apparent size of 16' and peak flux densities >160mK or >79mJy/beam area, and a list of 884 radio sources with a maximum apparent size of 16' and peak flux densities >200mK or >98mJy/beam area.

- Description:
- We analysed the 11cm Galactic Plane survey carried out with the Effelsberg 100-m telescope for small diameter sources. We present a list of 6483 radio sources with a maximum apparent size of 12' and peak flux densities >40mJy/beam area. Point-like sources are almost evenly distributed over the surveyed area, except that we miss some sources in the highly confused inner part of the Galaxy and the Cygnus X complex. At Galactic longitudes l>100deg the list of compact sources is almost complete above an integrated flux density limit of 70mJy. Most of them are extragalactic. Extended sources show a concentration towards the Galactic Plane. At longitudes l<100deg the scale height is about 0.6deg. An excess of about 900 extended sources is most likely of Galactic structure.

- Description:
- We report and discuss the results of a 22-cm radio survey carried out with the Australia Telescope Compact Array (ATCA) covering the A3528 complex, a chain formed by the merging ACO clusters A3528-A3530-A3532, located in the central region of the Shapley Concentration. Simultaneous 13-cm observations are also presented. Our final catalogue includes a total of 106 radio sources above the flux density limit of 0.8mJy. By cross-correlation with optical and spectroscopic catalogues we found 32 optical counterparts, nine of them belonging to the A3528 complex.

- Description:
- The 11 cm radio continuum radiation of the Galactic Plane is shown in the form of an atlas of contour maps covering the range l=357.4 to 76{deg}, |b|=1.5{deg} or less. The angular resolution is about 4.3arcmin and the sensitivity is 50mK T_B_ (or 20mJy/beam area). Additionally a catalog of 1212 small diameter radio sources has been compiled.

- Description:
- We conducted a large-scale survey for the cold infrared sources along the northern Galactic plane in the CO (J=1-0) line. There are 1912 IRAS sources selected on the basis of their color indices over the 12, 25, and 60{mu}m wave bands and their association with regions of recent star formation. A quick single-point survey was made toward all of the sources, which results in a detection of 1331 sources with significant CO emission above the detection limit of 0.7K, inferring a CO detection rate of 70%. Located over a wide range of the Galactocentric distances, the CO sources show high concentration toward the spiral arms. Among the detected sources, there are 351 sources found to have high-velocity CO wing emission. A search for the latest catalog of high-velocity CO flows (HVFs) from young stellar objects indicates that 289 sources are beyond the present lists of HVFs. These high-velocity wing sources provide us with a comprehensive database for the study of HVFs from young stellar objects. Using the known outflow sources as an effective indicator, we found that the detection rate for high-velocity wings during the quick survey is 62%, moderately sensitive in searching for new outflow sources. The CO detection rate of the IRAS sources, combined with the ratio of high-velocity wing, suggests that 41% of the CO sources are undergoing the HVF phase. In this paper, the CO spectra are presented along with the preliminary statistics of the data.
