1421. Planck ERCSC sources with 100 GHz flux excess

Planck ERCSC sources with 100 GHz flux excess

Description:
The Planck Early Release Compact Source Catalogue (ERCSC) includes nine lists of highly reliable sources, individually extracted at each of the nine Planck frequency channels. To facilitate the study of the Planck sources, especially their spectral behaviour across the radio/infrared frequencies, we provide a 'bandmerged' catalogue of the ERCSC sources. This catalogue consists of 15191 entries, with 79 sources detected in all nine frequency channels of Planck and 6818 sources detected in only one channel. We describe the bandmerging algorithm, including the various steps used to disentangle sources in confused regions. The multifrequency matching allows us to develop spectral energy distributions of sources between 30 and 857GHz, in particular across the 100GHz band, where the energetically important CO J=1->0 line enters the Planck bandpass. We find ~3{sigma}-5{sigma} evidence for contribution to the 100GHz intensity from foreground CO along the line of sight to 147 sources with |b|>{30deg}. The median excess contribution is 4.5+/-0.9 per cent of their measured 100 GHz flux density which cannot be explained by calibration or beam uncertainties. This translates to 0.5+/-0.1K.km/s of CO which must be clumped on the scale of the Planck 100GHz beam, i.e. ~10-arcmin. If this is due to a population of low-mass (~15M_{sun}_) molecular gas clumps, the total mass in these clumps may be more than 2000 M_{sun}_. Further, high-spatial-resolution, ground-based observations of the high-latitude sky will help shed light on the origin of this diffuse, clumpy CO emission.
1422. Planck galaxy cluster catalogue extension

Title:
Planck galaxy cluster catalogue extension
Short Name:

Date:

Publisher:
CDS
Description:
We present a catalogue of galaxy clusters detected in the Planck all-sky Compton parameter maps and identified using data from the WISE and SDSS surveys. The catalogue comprises about 3000 clusters in the SDSS fields. We expect the completeness of this catalogue to be high for clusters with masses larger than M500~=3x10^14^M_{sun}_, located at redshifts z<0.7. At redshifts above z~=0.4, the catalogue contains approximately an order of magnitude more clusters than the 2nd Planck Catalogue of Sunyaev-Zeldovich sources in the same fields of the sky. This catalogue can be used for identification of massive galaxy clusters in future large cluster surveys, such as the SRG/eROSITA all-sky X-ray survey.
1423. Planck 030 GHz Survey

Title:
Planck 030 GHz Survey
Short Name:
Planck030
Date:

Publisher:
NASA/GSFC HEASARC
Description:
Planck is ESA's third generation space based cosmic microwave background experiment, operating at nine frequencies between 30 and 857 GHz and was launched May 2009. Planck provides all-sky survey data at all nine frequencies with higher resolution at the 6 higher frequencies. It provides substantially higher resolution and sensitivity than WMAP. Planck orbits in the L2 Lagrange point. These data come from Release 1 of the Planck mission. &lt;p&gt; The original data are stored in HEALPix pixels. SkyView treats HEALPix as a standard projection but assumes that the HEALPix data is in a projection plane with a rotation of -45 degrees. The rotation transforms the HEALPix pixels from diamonds to squares so that the boundaries of the pixels are treated properly. The special HealPixImage class is used so that SkyView can use the HEALPix FITS files directly. The HealPixImage simulates a rectangular image but translates the pixels from that image to the nested HEALPix structure that is used by the HEALPix data. Users of the SkyView Jar will be able to access this survey through the web but performance may be poor since the FITS files are 150 to 600 MB in size and must be completely read in. SkyView will not automatically cache these files on the user machine as is done for non-HEALPix surveys. &lt;/p&gt; Data from the frequencies of 100 GHz or higher are stored in a HEALPix file with a resolution of approximately 1.7' while lower frequencies are stored with half that resolution, approximately 3.4'.

Description:
Planck is ESA's third generation space based cosmic microwave background experiment, operating at nine frequencies between 30 and 857 GHz and was launched May 2009. Planck provides all-sky survey data at all nine frequencies with higher resolution at the 6 higher frequencies. It provides substantially higher resolution and sensitivity than WMAP. Planck orbits in the L2 Lagrange point. <p> These data come from the legacy Release 3 of the Planck mission. <p> These products include polarization information available to visualize in several ways. The data contain Stokes parameters I, Q, and U, and in addition to these, it is possible to visualize the polarized intensity PI=sqrt(Q^2+U^2) and the polarization angle PA=1/2atan(U/Q). Note that at their native resolution of a few arcmin (depending on the frequency), these polarization data will appear very noisy. In order to visualize the polarization information, it is highly recommended that the data be resampled with the "Clip (intensive)" sampler and the result smoothed. That sampler will average all the data points within a given output pixel rather than the more common nearest neighbor. It will do this averaging before computing either PI or PA to reduce the effects of the noise. This sampler is set as the default for this survey. If the output pixel resolution is not significantly larger than the resolution, a smoothing of the output pixels will also be necessary. <p> Note also that Q and U are defined relative to a given co-ordinate system, in this case Galactic, and following the CMB convention (not the IAU); see https://lambda.gsfc.nasa.gov/product/about/pol_convention.cfm. This means that they will appear to vary rapidly near the pole of that coordinate system. The PI and PA will be computed correctly for any position on the sky. <p> The original data are stored in HEALPix pixels. SkyView treats HEALPix as a standard projection but assumes that the HEALPix data is in a projection plane with a rotation of -45 degrees. The rotation transforms the HEALPix pixels from diamonds to squares so that the boundaries of the pixels are treated properly.

1425. Planck high-z source candidates catalog (PHZ)
ID:

Title:
Planck high-z source candidates catalog (PHZ)
Short Name:
J/A+A/596/A100
Date:

Publisher:
CDS
Description:
The Planck mission, thanks to its large frequency range and all-sky coverage, has a unique potential for systematically detecting the brightest, and rarest, submillimetre sources on the sky, including distant objects in the high-redshift Universe traced by their dust emission. A novel method, based on a component-separation procedure using a combination of Planck and IRAS data, has been validated and characterized on numerous simulations, and applied to select the most luminous cold submillimetre sources with spectral energy distributions peaking between 353 and 857GHz at 5' resolution. A total of 2151 Planck high-z source candidates (the PHZ) have been detected in the cleanest 26% of the sky, with flux density at 545GHz above 500mJy. Embedded in the cosmic infrared background close to the confusion limit, these high-z candidates exhibit colder colours than their surroundings, consistent with redshifts z>2, assuming a dust temperature of Txgal=35K and a spectral index of {beta}xgal=1.5. Exhibiting extremely high luminosities, larger than 10^14^L_{sun}_, the PHZ objects may be made of multiple galaxies or clumps at high redshift, as suggested by a first statistical analysis based on a comparison with number count models. Furthermore, first follow-up observations obtained from optical to submillimetre wavelengths, which can be found in companion papers, have confirmed that this list consists of two distinct populations. A small fraction (around 3%) of the sources have been identified as strongly gravitationally lensed star-forming galaxies at redshift 2 to 4, while the vast majority of the PHZ sources appear as overdensities of dusty star-forming galaxies, having colours consistent with being at z>2, and may be considered as proto-cluster candidates. The PHZ provides an original sample, which is complementary to the Planck Sunyaev-Zeldovich Catalogue (PSZ2); by extending the population of virialized massive galaxy clusters detected below z<1.5 through their SZ signal to a population of sources at z>1.5, the PHZ may contain the progenitors of today's clusters. Hence the Planck list of high-redshift source candidates opens a new window on the study of the early stages of structure formation, particularly understanding the intensively star-forming phase at high-z.
1426. Planck Sunyaev-Zeldovich sources (PSZ2)
ID:
ivo://CDS.VizieR/J/A+A/594/A27
Title:
Planck Sunyaev-Zeldovich sources (PSZ2)
Short Name:
J/A+A/594/A27
Date:

Publisher:
CDS
Description:
We present the all-sky Planck catalogue of Sunyaev-Zeldovich (SZ) sources detected from the 29 month full-mission data. The catalogue (PSZ2) is the largest SZ-selected sample of galaxy clusters yet produced and the deepest systematic all-sky survey of galaxy clusters. It contains 1653 detections, of which 1203 are confirmed clusters with identified counterparts in external data sets, and is the first SZ-selected cluster survey containing >10^3^ confirmed clusters. We present a detailed analysis of the survey selection function in terms of its completeness and statistical reliability, placing a lower limit of 83% on the purity. Using simulations, we find that the estimates of the SZ strength parameter Y_5R500_ are robust to pressure-profile variation and beam systematics, but accurate conversion to Y_500_ requires the use of prior information on the cluster extent. We describe the multi-wavelength search for counterparts in ancillary data, which makes use of radio, microwave, infrared, optical, and X-ray data sets, and which places emphasis on the robustness of the counterpart match. We discuss the physical properties of the new sample and identify a population of low-redshift X-ray under-luminous clusters revealed by SZ selection. These objects appear in optical and SZ surveys with consistent properties for their mass, but are almost absent from ROSAT X-ray selected samples.
1427. Plate Centers, Epochs Lick/Mt. John Sky Survey

Title:
Plate Centers, Epochs Lick/Mt. John Sky Survey
Short Name:
VI/31
Date:

Publisher:
CDS
Description:
The "Lick Observatory Sky Atlas" (Lick Observatory, 1965) is a set of plates for 166 fields of 18 by 18 degrees, covering the sky from the north pole down to -30 degrees of declination. "The Mount John University Observatory Photographic Sky Survey" (Doughty et al., 1972) covers 142 similar fields from -15 degrees of declination down to the south pole. In the region of overlap, the fields are the same for the two surveys. Fields 1-46 of the Mount John survey cover the part of the sky (-45 degrees of declination to the south pole) not in the Lick survey; in a special limited edition published in 1972, this part is called the "Canterbury Sky Atlas" (Australia). The overlap between fields is 3 degrees. The plate scale is approximately 232 arc seconds per millimeter. The limiting magnitude is approximately 16. Neither survey is intended for astrometry or photometry; the Lick survey was originally done to obtain galaxy statistics (Shane and Wirtanen 1967). An excellent summary of several photographic sky surveys is given by Ingrao and Kasparian (1967). T. A. Nagy (1980) generated the dataset described, and also gathered most of the material used in the writing of this document.
