CHAMP (Chandra Multiwavelength Project) Hard X-Ray Emitting AGN

This table contains the results from an X-ray and optical analysis of 188 active galactic nuclei (AGN) identified from 497 hard X-ray (observed flux in the (2.0 - 8.0 keV) band &gt; 2.7 x 10&lt;sup&gt;-15&lt;/sup&gt; erg/cm&lt;sup&gt;2&lt;/sup&gt;/s) sources in 20 Chandra fields (1.5 square degrees) forming part of the Chandra Multiwavelength Project (ChaMP). These medium-depth X-ray observations enable the detection of a representative subset of those sources responsible for the bulk of the 2 - 8 keV cosmic X-ray background. Brighter than the survey&#39;s optical spectroscopic limit, the authors achieve a reasonable degree of completeness (77% of X-ray sources with counterparts r&#39; &lt; 22.5 have been classified): broad emission-line AGNs (62%), narrow emission-line galaxies (24%), absorption-line galaxies (7%), stars (5%), or clusters (2%). To construct a pure AGN sample, the authors required the rest-frame 2.0-8.0 keV luminosity (uncorrected for intrinsic absorption) to exceed 10&lt;sup&gt;42&lt;/sup&gt; erg s&lt;sup&gt;-1&lt;/sup&gt;, thereby excluding any sources that may contain a significant stellar or hot ISM component. The most luminous known star-forming or elliptical galaxies attain at most L&lt;sub&gt;X&lt;/sub&gt; = 10&lt;sup&gt;42&lt;/sup&gt; erg s&lt;sup&gt;-1&lt;/sup&gt;. Since many of the traditional optical AGN signatures are not present in obscured sources, high X-ray luminosity becomes the authors&#39; single discriminant for supermassive black hole accretion. They believe that almost all of the NELGs and ALGs harbor accreting SMBHs based on their X-ray luminosity. They find that 90% of the identified ChaMP sources have luminosities above this threshold. These selection criteria yield a sample of 188 AGNs from 20 Chandra fields with f(2-8 keV) &gt; 2.7 x 10&lt;sup&gt;-15&lt;/sup&gt; erg cm&lt;sup&gt;-2&lt;/sup&gt; s&lt;sup&gt;-1&lt;/sup&gt;, r&#39; &lt; 22.5, and L&lt;sub&gt;X&lt;/sub&gt; &gt; 10&lt;sup&gt;42&lt;/sup&gt; erg s&lt;sup&gt;-1&lt;/sup&gt;. The authors removed five objects identified as clusters based on their extended X-ray emission.

SAGE-SMC MIPS 24 micron Epoch 1 Catalog

The SAGE-SMC pro ject is a Cycle 4 legacy program on the Spitzer Space Telescope, entitled, SAGE-SMC: Surveying the Agents of Galaxy Evolution in the Tidally-Disrupted, Low-Metallicity Small Magellanic Cloud, with Karl Gordon (STScI) as the PI. The project overview and initial results are described in a paper by Gordon et al. (2010, in prep). The SMC was mapped at two different epochs dubbed Epochs 1 and 2 separated by 3 (IRAC) and 9 (MIPS) months, as this provides a 90-degree roll angle in the orientation of the detectors, which optimally removes the striping artifacts in MIPS and artifacts along columns and rows in the IRAC image data. In addition, these two epochs are useful constraints of source variability expected for evolved stars and some young stellar ob jects (YSOs). The IRAC and MIPS observations from the S3MC pathfinder survey of the inner 3 sq. deg. of the SMC (PI: Bolatto, referred to as Epoch 0) have been reduced using the same software. \n\nTo be included in each single epoch catalog, each 24 um source has to meet a number of criteria. The source had to be nearly point like with a correlation value >0.89. This removed approximately 2/3 of the entries in the single epoch source lists. In regions where there is a significant structure in the surrounding region (identified as having a sigma > 0.25 in a 120" width square box), the source had to have a correlation value >0.91. This requirement removed a small number of sources (70). Finally, all sources had to have signal-to-noise (S/N) values >5. The S/N used was that estimated from the StarFinder code using the mosaic uncertainty image added in quadrature with an 0.6% error due to the background subtraction. This removed 700 sources. The final Epoch 1 catalog likely has a few remaining unreliable sources, estimated to be at less than the 1% level. The Full List contains ALL sources extracted from the MIPS 24 um mosaics, thus a user should be aware that it contains spurious sources. For more details, see Section 4.1 of the SAGE-SMC Data Delivery Document.

Amazon iNfluence on the Atlantic: CarbOn export from Nitrogen fixation by DiAtom Symbioses (ANACONDAS)

This research project sutided the effects of the Amazon River plume on the carbon and nitrogen cycling of the western tropical North Atlantic Ocean. Phytoplankton blooms triggered by the river plume are thought to be responsible for significant cabon dioxide drawdown from the atmosphere. Our team came together to try to understand the factors affecting the phytoplankton bloom and also the fate of its production, including the amount of carbon dioxide taken up by the plume. Fieldwork in the western tropical North Atlantic onboard the RV Knorr took place along the salinity gradient of the river plume (16 ppt to 36 ppt) at a series of stations within and adjacent to the pluem.

VLA A2390 Cluster of Galaxies 1.4-GHz Source Catalog

This table contains the 1.4-GHz source catalog for the field of the cluster of galaxies A2390 as observed with the Very Large Array (VLA). This is one of the deepest radio images of a cluster field ever taken. The image covers an area of 34&#39; x 34&#39; with a synthesized beam of ~1.4&quot; and a noise level of ~5.6 &micro;Jy (&micro;Jy) near the field center. In the reference paper, the authors construct differential number counts for the central regions (radius &lt; 16&#39;) of this cluster, and find that the faint (S&lt;sub&gt;1.4GHz&lt;/sub&gt; &lt; 3 mJy) counts of A2390 are roughly consistent with the lowest blank field number counts. Their analyses indicate that the number counts are primarily from field radio galaxies. The authors suggest that the disagreement of their number counts for this cluster with those from a similarly deep observation of A370 that was also presented in the reference paper can be largely attributed to cosmic variance. The authors observed the A2390 cluster field with the VLA in the A configuration for ~31.4hr on-source during 2008 October. The field center is located at 21:53:36 +17:41:52 (J2000). This table was created by the HEASARC in August 2017 based on &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/ApJS/202/2/"&gt;CDS Catalog J/ApJS/202/2/&lt;/a&gt; file table2.dat. This file contained 699 entries for sources detected at 1.4 GHz in the A370 field, as well as 524 entries for sources detected at 1.4 GHz in the A2390 field. Only the latter are included in this HEASARC table, while the former can be found in the HEASARC&#39;s &lt;a href="vla3701p4.html"&gt;VLA3701P4&lt;/a&gt; table.

Australia Telescope 20-GHz (AT20G) High-Angular Resolution Catalog

This table contains the high-angular-resolution catalog for the Australia Telescope 20-GHz (AT20G) survey, using the high-angular-resolution 6-km antenna data at the baselines of ~4500 m of the Australia Telescope Compact Array (ATCA). The authors have used the data to produce the visibility catalog that separates the compact active galactic nuclei (AGNs) from the extended radio sources at the 0.15-arcsecond angular scale, corresponding to the linear size scale of 1 kpc at redshifts higher than 0.7. They find the radio population at 20 GHz to be dominated by compact AGNs constituting 77% of the total sources in the AT20G. In the paper, they introduce the visibility-spectra diagnostic plot, produced using the AT20G cross-matches with lower frequency radio surveys at 1 GHz [the NRAO VLA Sky Survey (NVSS: Condon et al. 1998, AJ, 115, 1693) and the Sydney University Molonglo Sky Survey (SUMSS: Mauch et al. 2003, MNRAS, 342, 1117)], that separates the 20-GHz population into distinct sub-populations of the compact AGNs, the compact steep-spectrum (CSS) sources, the extended AGN-powered sources and extended flat-spectrum sources. The extended flat-spectrum sources include a local thermal emitting population of high-latitude planetary nebulae and also gravitational lens and binary black hole candidates among the AGNs. The authors find a smooth transition in properties between the CSS sources and the AGN populations. The visibility catalog, together with the main AT20G survey, provides an estimate of angular size scales for sources in the AT20G and an estimate of the flux arising from central cores of extended radio sources. The identification of the compact AGNs in the AT20G survey provides high-quality calibrators for high-frequency radio telescope arrays and very large baseline interferometry observations. This table was created by the HEASARC in December 2013 based on machine-readable versions of Tables 2 and 3 from the reference paper which were obtained from the MNRAS web site.

Green Bank 6-cm (GB6) Radio Source Catalog

This table contains the Green Bank 6-cm (GB6) Radio Source Catalog. The Green Bank 4.85 GHz (6-cm wavelength) survey (Condon J.J., Broderick J.J., Seielstad G.A., Douglas K., &amp; Gregory P.C. in 1994AJ....107.1829C) was made with the NRAO seven-beam receiver on the (former) 91m telescope during 1986 November and 1987 October. The final set of sky maps covering the declination band 0 deg &lt; Dec. &lt; +75 deg was constructed with data from both epochs. Its noise and position errors are nearly a factor of 2^(1/2) smaller than in the epoch 1987 maps, from which the 87GB Catalog (&lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/VIII/14"&gt;CDS Catalog &lt;VIII/14&gt;&lt;/a&gt;) of 54,579 sources stronger than S ~ 25mJy was extracted. Therefore, the new maps were used to make the GB6 catalog of 75,162 discrete sources with angular sizes phi &lt;= 10.5 arcmin and flux densities S &gt;= 18mJy. The GB6 weighted differential source counts S^(5/2)n(S) between 18 mJy and 7 Jy agree well with evolutionary models based on independent data. This table was created by the HEASARC in July 2003 based on &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/VIII/40"&gt;CDS Catalog &lt;VIII/40&gt;&lt;/a&gt;.

Molonglo Galactic Plane Survey 2nd Epoch Compact Source Catalog

This table contains the Molonglo Galactic Plane Survey 2nd Epoch (MGPS-2) Compact Source Catalog. The MGPS-2 was carried out with the Molonglo Observatory Synthesis Telescope (MOST) at a frequency of 843 MHz and with a restoring beam of 45&quot; x 45&quot; cosec |(delta)|, where delta is the declination, making it the highest resolution large-scale radio survey of the southern Galactic plane to date. It covers the range |b| &lt; 10 degrees and 245 &lt; l &lt; 365 degrees, where l and b are the Galactic longitude and latitude, and is the Galactic counterpart to the SUMSS (&lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/VIII/81"&gt;CDS Cat. VIII/81&lt;/a&gt;) Catalog which covers that portion of the southern sky with delta &lt; -30 degrees, |b| &gt; 10 degrees. This version of the catalog (15-Aug-2007) consists of 48850 compact sources, made by fitting elliptical Gaussians in the MGPS-2 mosaics to a limiting peak brightness of 10 mJy/beam. The authors used a custom method (described in the associated reference publication) to remove extended sources from the catalog. Positions in the catalog are accurate to 1&quot; - 2&quot;. The authors have carried out an analysis of the compact source density across the Galactic plane and find that the source density is not statistically higher than the density expected from the extragalactic source density alone. See &lt;a href="http://www.astrop.physics.usyd.edu.au/mosaics"&gt;http://www.astrop.physics.usyd.edu.au/mosaics&lt;/a&gt; for access to the MGPS-2 mosaic images.

LMC Clusters Catalog

A new catalogue of clusters in the Large Magellanic Cloud has been constructed from searches of the IIIa-J component of the ESO/SERC Southern Sky Atlas. The catalogue contains coordinate and diameter measurements of 1762 clusters in a 25 deg x 25 deg area of sky centered on the LMC, but excluding the very crowded 3.5 square deg region around the Bar. The distribution of these clusters appears as two superimposed elliptical systems. The higher density inner system extends over about 8 deg; the lower density outer system can be represented by 13 deg X 10 deg disc inclined at 42 deg to the line of sight. There are suggestions of two weak &quot;arms&quot; in the latter. This is a service provided by NASA HEASARC .

VLA Orion Nebula Cluster Compact Source Catalog

This table contains a deep centimeter-wavelength catalog of the Orion Nebula Cluster (ONC), based on a 30-hr single-pointing observation with the Karl G. Jansky Very Large Array (JVLA) in its high-resolution A configuration using two 1-GHz bands centered on 4.7 and 7.3 GHz. A total of 556 compact sources were detected in a map with a nominal rms noise of 3 &micro;Jy/beam, limited by complex source structure and the primary beam response. Compared to previous catalogs, these detections increase the sample of known compact radio sources in the ONC by more than a factor of seven. The new data show complex emission on a wide range of spatial scales. Following a preliminary correction for the wideband primary-beam response, the authors determine radio spectral indices for 170 sources whose index uncertainties are less than +/-0.5. They compare the radio to the X-ray and near-infrared point-source populations, noting similarities and differences. The observations were carried out with the JVLA of the National Radio Astronomy Observatory on 2012 September 30 and October 2-5 under the auspices of the project code SD630. Data were taken using the VLA&#39;s C-band (4-8 GHz) receivers in full polarization mode, with two 1-GHz basebands centered at 4.736 and 7.336 GHz to provide a good baseline for source spectral index determination. Apart from the first epoch, the field was simultaneously observed with the Chandra X-Ray Observatory. Mostly of interest for variability information, these data will be presented as part of a follow-up paper. This table was created by the HEASARC in September 2016 based on &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/ApJ/822/93"&gt;CDS Catalog J/ApJ/822/93&lt;/a&gt; file table1.dat (the compact source catalog).
