Cygnus TeV Source Chandra X-Ray Point Source Catalog

A 50 ks Chandra observation of the unidentified TeV source in Cygnus reported by the High Energy Gamma-Ray Astronomy (HEGRA) collaboration reveals no obvious diffuse X-ray counterpart. However, 240 pointlike X-ray sources are detected within or nearby the extended TeV J2032+4130 source region, of which at least 36 are massive stars and two may be radio emitters. That the HEGRA source is a composite, having as a counterpart the multiple pointlike X-ray sources that are observed, cannot be ruled out. Indeed, the distribution of pointlike X-ray sources appears nonuniform and concentrated broadly within the extent of the TeV source region. A hypothesis is offered for the origin of the very high energy gamma-ray emission in Cyg OB2 based on the local acceleration of TeV-range cosmic rays and the differential distribution of OB versus less massive stars in this association. The region of TeV J2032+4130 was observed by Chandra on 2004 July 12 for a total effective exposure time of 48,728 seconds using the Advanced CCD Imaging Specrometer imaging array (ACIS-I). The observation was centered on J2000.0 coordinates (RA, Dec) = )20 32 07.0, +41 30 30). This table contains the list of the 240 pointlike sources which were detected in the ACIS-I data and their 2MASS near-IR counterparts, if any are found within 3&quot; of the X-ray sources. 130 (54%) of the 240 X-ray sources have 2MASS counterparts within these error radii. This table was created by the HEASARC in February 2007 based on the electronic version of Table 1 from the above reference which was obtained from the ApJ website.

Einstein IPC Ultrasoft Sources Catalog

A survey of the entire Einstein IPC database (a total of 5934 sources) has been carried out in order to select objects with strong components of ultrasoft X-ray emission (i.e., emission below 0.5 keV). The selection criteria were based on ratios of counts within three broad energy bands (i.e., X-ray &quot;colors&quot;). A total of 516 objects have been selected, with 202 (39%) having been identified through correlations with other databases. Of the currently identified objects, 45% are active galactic nuclei, 28% are stellar objects, 6% are &quot;normal&quot; galaxies and galaxy clusters, and the remaining 21% are &quot;nonstellar&quot; Galactic objects such as cataclysmic variables, pulsars, and white dwarfs. The selection of sources for this survey was based on the analysis of counts in three broad energy bands defined as C1=0.16-0.56 keV, C2=0.56-1.08 keV, and C3= 1.08-3.5 keV. Ratios of these three bands constituted X-ray &#39;colors&#39; which in turn were used to estimate the shape of the spectrum over the IPC bandpass. Based on models of X-ray spectra folded through the IPC response function, the following criteria were determined for the selection of ultrasoft sources: C1&gt;0 and R1=C2/C1&lt;0.36. These criteria guarantee an intrinsically soft X-ray spectrum that can be modeled by blackbody temperatures kT&lt;50 keV, power-law spectral indices of &gt;=2, or thermal plasma temperatures T&lt;1 MK (million K). Details of the data analysis can be found in the Thompson et al. (1998) reference. This database was created by the HEASARC in April 1999 based on tables provided by the catalog authors to the CDS/ADC. This is a service provided by NASA HEASARC .

Elevated plus-maze performance of Fischer-344 rats as a function of age and of exposure to 56Fe particles

The aging process is characterized by a series of changes in neurochemical functioning and in motor and cognitive performance. In addition to changes in cognitive/behavioral performance, aged rats also show an increase in baseline anxiety measured using the elevated plus maze. Exposure to 56Fe particles, a component of cosmic rays, produces neurochemical and behavioral changes in young animals which are characteristic of aged organisms. The present study was designed to determine the relationships between aging and exposure to 56Fe particles on anxiety. Fischer 344 (F344) rats, which were 2, 7, 12, and 16 months of age at the time of irradiation, were exposed to 56Fe particles (50 to 200 cGy). Concordant with previous results, the oldest rats spent less time exploring the open arms of the maze. Exposure to 56Fe particles also produced decreased exploration of the open arms of the plus maze. The dose needed to produce increased levels of anxiety was a function of age at the time of irradiation. The dose of 56Fe particles needed to produce a decrease in open arm exploration was significantly lower in the rats that were irradiated at 7 and 12 months of age than in the rats irradiated at 2 months of age. These results suggest the possibility that exposing middle aged astronauts to cosmic rays during exploratory class missions outside the magnetosphere, and the resultant effects on exploration induced anxiety, may affect their ability to successfully complete mission requirements. This dataset derives results from the Elevated Plus Maze assay. The data derived from this study are from the behavioral assays Novel Object Recognition and Operant Conditioning (bar press). The original data derived from this study by Rabin et al. was transformed and used as part of a predictive modeling study by Dr. Mora, Dr. Wyrobek, Dr. Ben Brown et al. The study files contain both the original data and the transformed data produced by both research teams. For questions regarding the original study data and methods/assays, please contact the original study investigator and publication author Dr. Bernard Rabin (rabin@umbc.edu). For questions about the predictive modeling data files or how they were generated, please contact Dr. Mora (animora@berkeley.edu).

Persistence of Escherichia coli in the microbiomes of mizuna mustard (Brassica rapa var. japonica) - does seed sanitization matter?

Seed sanitization via chemical processes removes/reduces microbes from the external surfaces of the seed and thereby could have an impact on the plants' health or productivity. To determine the impact of seed sanitization on the plants' microbiome and pathogen persistence, sanitized and unsanitized seeds from two leafy green crops, red Romaine lettuce (Lactuca sativa cv. 'Outredgeous') and mizuna mustard (Brassica rapa var. japonica) were exposed to Escherichia coli and grown in controlled environment growth chambers simulating environmental conditions aboard the International Space Station. Plants were harvested at four intervals from 7 days post-germination to maturity. The bacterial communities of leaf and root were investigated using the 16S rRNA sequencing while quantitative polymerase chain reaction (qPCR) and heterotrophic plate counts were used to reveal the persistence of E. coli. Result: E. coli was detectable for longer periods of time in plants from sanitized versus unsanitized seeds and was identified in root tissue more frequently than in leaf tissue. 16S rRNA sequencing showed dynamic changes in the abundance of members of the phylum Proteobacteria, Firmicutes, and Bacteroidetes in leaf and root samples of both leafy crops. We observed minimal changes in the microbial diversity of lettuce or mizuna leaf tissue with time or between sanitized and unsanitized seeds. Beta-diversity showed that time had more of an influence on all samples versus the E. coli treatment. Conclusion: Our results indicated that the seed surface sanitization, a current requirement for sending seeds to space, could influence the microbiome. Insight into the changes in the crop microbiomes could lead to healthier plants and safer food supplementation.

Specific Host Metabolite and Gut Microbiome Alterations Are Associated with Bone-loss During Spaceflight

Understanding the axis of the human microbiome and physiological homeostasis is an essential task in managing deep-space travel associated health risks. The NASA led Rodent Research 5 mission enabled an ancillary investigation of the gut microbiome varying exposure to microgravity (flight) relative to ground controls in the context of previously shown bone mineral density (BMD) loss that was observed in these flight groups. We demonstrate elevated abundance of Lactobacillus murinus and Dorea sp. during microgravity exposure relative to ground control through whole genome sequencing and 16S rRNA analyses. Specific functionally assigned gene clusters of Lactobacillus murinus and Dorea sp. capable of producing metabolites, lactic acid, leucine/isoleucine, and glutathione are enriched. These metabolites are elevated in the microgravity-exposed host serum through LC-MS/MS metabolomic analysis. Along with BMD loss, ELISA analysis reveals increases of osteocalcin and reductions in tartrate-resistant acid phosphatase 5b signifying additional loss of bone homeostasis in flight.

Dose-dependent skeletal deficits due to varied reductions in mechanical loading in rats (Tibia - pQCT)

Reduced skeletal loading leads to marked bone loss. Animal models of hindlimb suspension are widely used to assess alterations in skeleton during the course of complete unloading. More recently, the effects of partial unloading on the musculoskeletal system have been interrogated in mice and rats, revealing dose-dependent effects of partial weight bearing (PWB) on the skeleton and skeletal muscle. Here, we extended these studies to determine the structural and functional skeletal alterations in 14-week-old male Wister rats exposed to 20%, 40%, 70%, or 100% of body weight for 1, 2, or 4 weeks (n  equals 11–12/group). Using in vivo pQCT, we found that trabecular bone density at the proximal tibia declined in proportion to the degree of unloading and continued progressively with time, without evidence of a plateau by 4 weeks. Ex vivo measurements of trabecular microarchitecture in the distal femur by microcomputed tomography revealed deficits in bone volume fraction, 2 and 4 weeks after unloading. Histologic analyses of trabecular bone in the distal femur revealed the decreased osteoblast number and mineralizing surface in unloaded rats. Three-point bending of the femoral diaphysis indicated modest or no reductions in femoral stiffness and estimated modulus due to PWB. Our results suggest that this rat model of PWB leads to trabecular bone deterioration that is progressive and generally proportional to the degree of PWB, with minimal effects on cortical bone. This study derives results from the pQCT assay using tibia tissue.

First Byurakan Survey Blue Stellar Objects Catalog

Eleven lists of blue stellar objects (BSOs) found in the First Byurakan Survey (FBS) low-dispersion spectroscopic plates were published in the journal Astrophysics in the period 1990-1996, The selection was carried out in the region with declinations +33 deg. &lt; delta &lt; +45 deg. and delta &gt; +61 degrees with a surface area of 4000 square degrees. As a result, the present catalog of the FBS blue stellar objects (BSOs) has been compiled. Its preliminary version has been available at CDS since 1999. The author has revised and updated the FBS BSOs catalog with the new data from recently published optical and multi-wavelength catalogs to give access to all available data and make further comparative studies of the properties of these objects possible. The author has made cross-correlations of the FBS BSOs catalog with the MAPS , USNO-B1.0, SDSS, and 2MASS catalogs, as well as with ROSAT, IRAS, NVSS, and FIRST catalogs , added updated SIMBAD and NED data for the objects, and provided accurate DSS1 and DSS2 positions and revised photometry. The author also checked the objects for proper motion and variability. A refined classification for the low-dispersion spectra in the Digitized First Byurakan Survey (DFBS) was carried out. The revised and updated catalog of 1103 FBS blue stellar objects is presented here. (The catalog in fact contains 1101 objects, as 2 pairs of objects turned to be identical; however, the author has kept all objects in the list on order to allow users to enter and find objects by all accepted FBS names). The FBS blue stellar objects catalog can be used to study a complete sample of white dwarfs, hot sub-dwarfs, horizontal-branch B (HBB) stars, cataclysmic variables, bright AGN, and to investigate individual interesting objects. This table was created by the HEASARC in October 2008 based on the CDS table III/258 file fbs.dat. This latter catalog supersedes the previous edition (Abrahamian et al. 1999, &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/II/223"&gt;CDS Cat. II/223&lt;/a&gt;) This is a service provided by NASA HEASARC .

Effects of Spaceflight on Bone Microarchitecture in the Axial and Appendicular Skeleton in Growing Ovariectomized Rats from STS-62

This study investigated the effects of a 14-day spaceflight on bone mass, density and microarchitecture in weight bearing (femur and humerus) and non-weight bearing (2nd) lumbar vertebra and calvarium) bones in the context of ovarian hormone insufficiency. 12-week-old Fisher 344 rats were ovariectomized 2 weeks before flight and randomized into one of three groups: 1) baseline (n equals 6), 2) ground control (n equals 12) or 3) spaceflight (n equals 12). Additional ground-based ovary-intact rats provided age-matched reference values at baseline (n equals 8) and landing (n equals 10). Ovariectomy resulted in bone- and bone compartment-specific deficits in cancellous bone volume fraction. Spaceflight resulted in lower cortical bone accrual in the femur but had no effect on cortical bone in the humerus or calvarium. Cancellous bone volume fraction was lower in flight animals compared to ground control animals in lumbar vertebra and distal femur metaphysis and epiphysis; significant differences were not detected in the distal humerus. Bone loss (compared to baseline controls) in the femur metaphysis was associated with lower trabecular number, whereas trabecular thickness and number were lower in the epiphysis. This dataset is only for the ovariectomized animals. In summary, the effect of spaceflight on bone microarchitecture in ovariectomized rats was bone-and bone compartment-specific but not strictly related to weight bearing. This dataset derives results from the micro–computed tomography (mCT) assay.

Giant Metrewave Radio Telescope Lockman Hole 610-MHz Radio Source Catalog

This table contains a source catalog based on observations of the Lockman Hole with the Giant Metrewave Radio Telescope (GMRT) taken at 610 MHz (49 cm). Twelve pointings were observed, covering a total area of ~5 deg&lt;sup&gt;2&lt;/sup&gt; with a resolution of 6 x 5 arcsec&lt;sup&gt;2&lt;/sup&gt;, position angle +45 degrees. The majority of the pointings have an rms noise of ~ 60 &micro;Jy/beam (&micro;Jy/beam) before correction for the attenuation of the GMRT primary beam. The techniques used for data reduction and the production of a mosaicked image of the region are described in the reference paper, where the final mosaic is presented, along with a catalog of 2845 sources detected above the 6-sigma threshold which is contained in this table. In the paper, radio source counts are calculated at 610 MHz and combined with existing 1.4-GHz source counts, in order to show that pure luminosity evolution of the local radio luminosity functions for active galactic nuclei and starburst galaxies is sufficient to account for the two source counts simultaneously. The &#39;central region&#39; of the Lockman Hole, consisting of 12 pointings spaced by 36 arcminutes in a hexagonal pattern (shown in Fig. 1 of the reference paper) was observed on 2004 July 24 and 25 using the GMRT. The observations were made in two 16-MHz sidebands centered on 610 MHz, each split into 128 spectral channels, with a 16.9s integration time. This table was created by the HEASARC in February 2012 based on &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/MNRAS/387/1037"&gt;CDS Catalog J/MNRAS/387/1037&lt;/a&gt; file catalog.dat.

GO JUP SSD DERIVED ELECTRON FLUX V1.0

The Galileo star scanner is providing data on the instantaneous      flux of 1.5 to 30 MeV electrons in the Jovian environment. It is      able to measure fluxes of ~1 x 105 electrons cm-2 sec-1 or greater      which generally means the data are usable inside of about 12 and      rarely as far out as 16.5 Jovian Radii (RJ). Typically, the data      points are spaced about 400 or 80 seconds apart with infrequent      periods of more rapid data depending upon the operational mode.      It should be noted that data are generally accurate in time to      only within 20 seconds without special processing. Pitch angle      information generally cannot be extracted from this data set.      Separate files exist for the Jovian insertion event (J0) and      all subsequent perijove passes except J5 which occurred during      a period of solar conjunction.

Galactic Center P-Band (330 MHz) Survey

The Galactic Center P-Band (330 MHz) Survey (GCPS) is based on wide-field, subarcminute-resolution Very Large Array (VLA) imagery of the Galactic center region at 330 MHz. With a resolution of ~7&quot;x12&quot; and an rms noise of 1.6 mJy/beam, this image represented a significant increase in resolution and sensitivity over the previously published VLA image at this frequency. The improved sensitivity more than tripled the census of small-diameter sources in the region, resulted in the detection of two new nonthermal filaments (NTFs), 18 NTF candidates, and 30 pulsar candidates, revealed previously known extended sources in greater detail, and has resulted in the first detection of Sagittarius A* in this frequency range. Two sets of observations were obtained. The first was conducted at 330 MHz in the A configuration of the VLA in 1996 October. The second set of P-band observations were obtained in the A and B configurations of the VLA between 1998 March and 1999 May. This Browse table was created by the HEASARC in May 2005 based on the &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/AJ/128/1646"&gt;CDS Catalog J/AJ/128/1646&lt;/a&gt;, tables table2.dat and table3.dat.
