M 83 Chandra X-Ray Binary Classifications Using HST

Building on recent work by Chandar+ (2020, J/ApJ/890/150), the authors constructed X-ray luminosity functions (XLFs) for different classes of X-ray binary (XRB) donors in the nearby star-forming galaxy M 83. Rather than classifying low-versus high-mass XRBs based on the scaling of the number of X-ray sources with stellar mass and star formation rate, respectively, this catalog utilized multi-band Hubble Space Telescope imaging data to classify each Chandra-detected compact X-ray source as a low-mass (i.e., donor mass &lt; ~3M&lt;sub&gt;sun&lt;/sub&gt;), high-mass (donor mass &gt; ~8M&lt;sub&gt;sun&lt;/sub&gt;), or intermediate-mass XRB based on either the location of its candidate counterpart on optical color-magnitude diagrams or the age of its host star cluster. In addition to the standard (single and/or truncated) power-law functional shape, the authors approximated the resulting XLFs with a Schechter function. They identified a marginally significant (at the 1-sigma to 2-sigma level) exponential downturn for the high-mass XRB XLF, at l~38.48&lt;sub&gt;-0.33&lt;/sub&gt;&lt;sup&gt;+0.52&lt;/sup&gt; (in log CGS units). In contrast, the low- and intermediate-mass XRB XLFs, as well as the total XLF of M 83, are formally consistent with sampling statistics from a single power law. This method suggests a non-negligible contribution from low- and possibly intermediate-mass XRBs to the total XRB XLF of M 83, i.e., between 20% and 50%, in broad agreement with X-ray-based XLFs. More generally, the authors caution against considerable contamination from X-ray emitting supernova remnants to the published, X-ray-based XLFs of M 83, and possibly all actively star-forming galaxies. This table presents a fully classified catalog of X-ray sources in M 83 that builds upon the deep Chandra ACIS imaging data published in Lehmer+ 2019 (J/ApJS/243/3). Out of a total of 456 point-like sources brighter than 10&lt;sup&gt;35&lt;/sup&gt;erg/s, this work restricts the analysis to the 325 objects that fall within the M 83 HST footprint. HST observations of M 83 were taken with the WFC3/UVIS instrument, spanning seven fields that each cover approximately 162&quot; x 162&quot; for a total mosaic area of ~43 arcmin&lt;sup&gt;2&lt;/sup&gt;. All observations were obtained between 2009 August and 2012 September by R. O&#39;Connell (Prop ID. 11360) and W. Blair (Prop ID. 12513), with exposure times ranging from ~1.2 to 2.7 ks for each image. Images were downloaded from the Hubble Legacy Archive (HLA). In general, BVI images are created using the F438W, F547M, and F814W filters. The central field, which includes the galaxy nucleus, uses the broader F555W V-band filter, rather than F547M. The authors also use U-band images (F336W) to help calculate cluster ages. This table was created by the HEASARC in March 2023 based upon the &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/ApJ/912/31"&gt;CDS Catalog J/ApJ/912/31&lt;/a&gt; file tablea2.dat.

Transcriptional profiling of gastrocnemius muscle from rats flown on the SLS-1 mission

The Spacelab Life Sciences (SLS) program was a series of payloads that used the facilities of an entire Spacelab module to conduct a variety of life science investigations. The general objective of the research in the SLS programs was to study the acute and chronic changes that living systems undergo during exposure to the space environment. The specific objective of the Spacelab Life Sciences-1 (SLS-1) mission was to study the responses of rats to spaceflight and a period of re-exposure to Earth’s gravity.  In addition, this mission allowed for the detailed studies on rodents flown in two different types of habitats (individual and group housed).  The goals were to (1) verify the Research Animal Housing Facility (RAHF) and Animal Enclosure Module (AEM) and the capability of these facilities to maintain healthy animals for experimental use; (2) compare changes in rats exposed to spaceflight to the changes seen at 1g in rats housed in identical flight hardware and exposed to a similar flight environmental profile; and (3) compare the changes seen in rats flown in the RAHF with those seen in rats flown in the AEM and to identify housing-related effects. To this end, a flight group (FLT) of 65-day old male Sprague-Dawley rats were launched from Kennedy Space Center (KSC) on 6/5/1991 and singly housed in Research Animal Housing Facility (RAHF) on the shuttle for 9 days before being returned alive to Earth. After splashdown, the FLT animals were decapitated, and dissection occurred on 6/14/1991. Asynchronous ground control animals (GC) were exposed to identical environmental conditions as the FLT group except for noise profile, acceleration, and vibration. GC animals were housed in vivarium cages and dissection occurred on 7/19/1991.  Upon dissection, gastrocnemius-lateral tissues were preserved in liquid nitrogen and stored at -70 C before RNA was extracted.  The dataset features 7 FLT and 5 GC samples.  All libraries were generated using the QIAseq UPX 3’ Transcriptome kit that enables 3’ gene expression analysis from purified RNA and sequenced around 40 M clusters at SE 93 bp.

CANDELS H-Band Selected Chandra Source Catalog

Improving the capabilities of detecting faint X-ray sources is fundamental to increase the statistics on faint high-z AGN and star-forming galaxies. The authors performed a simultaneous maximum likelihood point-spread function (PSF) fit in the 0.5-2 keV and 2-7 keV energy bands of the 4 Ms Chandra Deep Field South (CDFS) data at the position of the 34,930 CANDELS H-band selected galaxies. For each detected source, they provide X-ray photometry and optical counterpart validation. The authors validated this technique by means of a ray-tracing simulation, and detected a total of 698 X-ray point-sources with a likelihood L &gt; 4.98 (i.e.&gt; 2.7sigma). They show that the prior knowledge of a deep sample of Optical-NIR galaxies leads to a significant increase of the detection of faint (i.e. ~ 10&lt;sup&gt;-17&lt;/sup&gt; erg s&lt;sup&gt;-1&lt;/sup&gt; cm&lt;sup&gt;-2&lt;/sup&gt; in the 0.5-2 keV band) sources with respect to &quot;blind&quot; X-ray detections. By including previous catalogs, this work increases the total number of X-ray sources detected in the 4 Ms CDFS, CANDELS area to 793, which represents the largest sample of extremely faint X-ray sources assembled to date. These results suggest that a large fraction of the optical counterparts of our X-ray sources determined by likelihood ratio actually coincides with the priors used for the source detection. Most of the newly detected sources are likely star-forming galaxies or faint absorbed AGN. The authors identified a few sources with putative photometric redshift z &gt; 4. Despite the low number statistics, this sample significantly increases the number of X-ray selected candidate high-z AGN. The 4-Ms CDFS consists of 23 observations described in Table 1 of Luo et al. (2008, ApJS, 179, 19) plus 31 other pointings described in Xue et al. (2011, ApJS, 195, 10, hereafter X11) for a total exposure of ~4 Ms. For the purpose of this paper, the authors employed only observations taken with a focal temperature of &lt;= -120 C, since at higher temperatures the background cannot be modeled with their technique. This table was created by the HEASARC in July 2016 based on &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/ApJ/823/95"&gt;CDS Catalog J/ApJ/823/95&lt;/a&gt; file catalog.dat. Some of the values for the name parameter in the HEASARC&#39;s implementation of this table were corrected in April 2018. This is a service provided by NASA HEASARC .

Abell Clusters Measured Redshifts Catalog

The all-sky ACO (Abell, Corwin and Olowin 1989, ApJS, 70, 1) Catalog of 4073 rich clusters of galaxies and 1175 southern poor or distant S-clusters has been searched for published redshifts. Data for 1059 of them were found and classified into various quality classes, e.g. to reduce the problem of foreground contamination of redshifts. Taking the ACO selection criteria for redshifts, a total of 992 entries remain, 21 percent more than ACO. Redshifts for rich clusters are now virtually complete out to a redshift z of 0.05 in the north and of 0.04 in the south. In the north, the magnitude-redshift (m_10 - z) relation agrees with that of Kalinkov et al. (1985, Astr. Nachr., 306, 283). For the southern rich clusters, minor adjustments to the m_10 - z relation of ACO are suggested, while for the S-clusters the redshifts are about 30 percent lower than estimated. This table was created by the HEASARC in May 2010 based on &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/VII/165A"&gt;CDS Catalog VII/165A&lt;/a&gt; file catalog.dat.

Characterizing Epigenetic Changes in Methylation Mutants (elp2-5 and met1-7) in Response to Spaceflight. [Bisulfite-Seq]

Epigenetic changes in the DNA methylome are increasingly shown to play an integral role in regulating gene expression necessary for plants’ adaption to environmental stressors. Plants subjected to the novel environment of spaceflight onboard the International Space Station (ISS), show stress-related transcriptomic changes most notably associated with pathogen stress response. Here, we investigate how known terrestrial stress associated epigenetic modulations might play a role in spaceflight adaptation. To examine the role of 5mCyt in spaceflight adaptation, the APEX04-EPEX experiment conducted onboard the ISS evaluated the spaceflight altered genome wide methylation profiles of two methylation regulating gene mutants, methyltransferase 1 (met1-7) and elongator complex subunit 2 (elp2-5), that are involved in pathogen defense response, along with a wild type Col-0 control. MethylSeq and RNAseq analyses were performed on both spaceflight grown samples and ground grown controls. In addition, the epigenetics effects that may contribute to the differential gene expression patterns observed between leaf and root tissues were also investigated in an organ-specific manner.

Revised Luyten Half-Second (LHS) Catalog

The Revised Luyten Half-Second (LHS) Catalog contains refined coordinates and proper motion data for the high proper motion (HPM) stars listed in the Original Luyten Half-Second (LHS) catalog. The positional uncertainty in the Original LHS catalog is typically &gt;10&quot; and is often &gt;30&quot;. The authors of the Revised LHS Catalog used the digital scans of the Palomar Observatory Sky Survey (POSS) I and POSS II plates to derive more accurate positions and proper motions for these objects. Out of the 4470 candidates in the LHS catalog, 4323 objects were manually re-identified in the POSS I and POSS II scans. A small fraction of the stars were not found due to the lack of finder charts and digitized POSS II scans. The uncertainties in the revised positions are typically ~2&quot;, but can be as high as ~8&quot; in a few cases, which is a large improvement over the original data. Cross-correlation with the Tycho-2 and Hipparcos catalogs yielded 819 candidates (with red magnitude m_R &lt;~12. For these brighter sources, the position and proper motion data were replaced with the more accurate Tycho/Hipparcos data. In total, there are revised proper motion measurements and coordinates for 4040 stars and revised coordinates for 4330 stars. This table was created by the HEASARC in October 2002 based on &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/I/279"&gt;CDS Catalog I/279&lt;/a&gt; (the 24-May-2002 version of the file catalog.dat).

Single cell transcriptional profiling of spleens from mice flown on Rodent Research Reference Mission-2 (RRRM-2)

In the Rodent Research Reference Mission (RRRM-2), forty female C57BL/6NTac mice were flown on the International Space Station. To assess differences in outcomes due to age, twenty 12 week-old and twenty 29 week-old mice were flown, respectively. To directly assess spaceflight effects, half of the young and old mice (10 old, 10 young) were sacrificed on-orbit after 55-58 days (ISS Terminal, ISS-T), while the other half (10 old, 10 young) were returned live to Earth after 32 days and allowed to recover for 24 days (Live Animal Return, LAR) before sacrifice. ISS-T and LAR mice were the same age at sacrifice. Both the ISS-T and LAR animals had independent ground controls (10 mice per group housed in flight hardware in matched environmental conditions), basal controls (10 mice per group sacrificed 2 days before launch), and vivarium controls (10 mice per group housed within standard vivarium habitats). Thus RRRM-2 included a total of 160 mice. This study includes single cell transcriptional profiling data from the spleens from 4 young LAR flight animals, 4 old LAR flight animals, 4 young LAR ground control animals, and 4 old LAR ground control animals.

NEW HORIZONS  SDC JUPITER ENCOUNTER  RAW V4.0

This data set contains Raw data taken by the New Horizons  Student Dust Counter  instrument during the  Jupiter encounter  mission phase. This is VERSION 4.0 of this data set.   For the Jupiter encounter mission phase, SDC collected no science  data during the Jupiter flyby, as the requisite spacecraft  configuration prevented SDC from operating. There were some very  sparse data taken from December, 2006 through April, 2007, and  some of very short (or zero) duration after the Jupiter flyby from  April, 2007 through June, 2007.   The changes in Version 4.0 were re-running of the ancillary data  in the data product, updated geometry from newer SPICE kernels,  minor editing of the documentation, catalogs, etc., and resolution  of liens from the December, 2014 review, plus those from the May,  2016 review of the Pluto Encounter data sets. No new observations  were added with Version 4.0.

Metagenome profiling of feces from mice flown on the RR-23 mission

The objective of the RR-23 mission was to better understand the effects of spaceflight on the eyes, specifically on the structure and function of the arteries, veins, and lymphatic vessels that are needed to maintain vision. To this end, twenty male, C57BL/6J, 16-17 weeks-old mice were delivered to the ISS on SpaceX-21 in a single transporter, transferred to two rodent habitats, and maintained in microgravity for 38 days. Flight mice were then returned to Earth alive (Jan 13th, 2021). After splashdown in the Atlantic Ocean, mice were transported to Kennedy Space Center via helicopter. The 20 Flight, 20 Habitat Ground Control (HGC), and 20 Vivarium Ground Control (VGC) mice were removed from Rodent Transporters (Flight and HGC) or vivarium cages (VGC), placed into shipping containers, and flown to Texas A and M University. There, mice underwent post-flight procedures, before euthanasia and tissue collection. Flight, HGC and VGC animals were euthanized and dissected on Jan 14th, 17th or 20th of 2021, respectively. Feces were removed from the animals and preserved by flash freezing in liquid nitrogen and stored at -80 ˚C until DNA was extracted, and libraries generated and sequenced (target 10 M clusters per sample, PE 250 bp). This dataset features 9 samples from the Flight group, 9 samples from the HGC group, and 9 samples from the VGC group.

Transcriptional profiling of spleens from mice flown on the RR-9 mission

The objective of the Rodent Research-9 (RR-9) mission was to use mice to understand the molecular basis of phenomena that affect astronauts during long-duration spaceflight, particularly visual impairment, and joint tissue degradation. To this end, a flight group (FLT) of 10-week-old male C57BL/6J mice were launched from Kennedy Space Center (KSC) on 8/14/2017 and housed in Rodent Habitats on the ISS for 33 days before being returned alive to Earth. After splashdown in the Pacific Ocean, the animals were transported to Loma Linda University (LLU) for testing, euthanasia, and dissection on 9/18/2018. Ground Control (GC) studies were planned to commence at KSC approximately one-week after the conclusion of the flight experiments. However, all the GC mouse studies at KSC had to be cancelled due to Hurricane Irma and potential adverse effects on the animal housing facility. The GC studies were therefore rescheduled and begun in May 2018. The GC was euthanized and dissected 6/18/2018 - 6/20/2018. Because this resulted in a different cohort of mice being used for the GC controls as compared to the flight (FLT) groups, two cohort controls were included in the study. The first, Cohort Control 1 (CC_C1), was from the same cohort as the FLT animals and was sacrificed and dissected 4 days after the FLT group (9/22/2017). The second, Cohort Control 2 (CC_C2), was from the same cohort as the GC, and was sacrificed and dissected 2-8 days after the GC, (6/24/2018 - 6/26/2018). The CC_C1 and CC_C2 groups were housed in standard cages and fed standard chow in contrast to all other groups which received Rodent Foodbars. Upon dissection, spleen tissues were preserved in liquid nitrogen and stored at 80 C before RNA was extracted. Only the flight (FLT, n of 10) and Ground Control (GC, n of 10) samples were processed and analyzed in this study. Libraries were generated using a 3’ Tag-seq approach and sequenced at a targeted depth of 40 M clusters (SE 93 bp).
