Daily solar spectral irradiance data from the SOLSTICE instrument on the Upper Atmosphere Research Satellite (UARS), covering the 119 to 420 nm ultraviolet wavelength range at 1 nm resolution. The dataset includes daily average integrated intensities for specific spectral lines and core-wing ratios, normalized to 1 AU and corrected for instrument degradation. It was designed to track solar output variations from minutes to the 22-year solar magnetic field cycle.
Raw and processed analytical data supports a comparative evaluation of protein quantification methods. The dataset contains results from five techniques applied to commercial UHT oat, almond, soy, and bovine milk samples, as well as protein standards. Data was collected at Macquarie University and the Australian Proteome Analysis Facility.
Environment and Climate Change Canada provides water quality and suspended sediment monitoring data from the Great Lakes connecting channels. The dataset includes the St. Marys River, St. Clair River, Detroit River, Niagara River, and St. Lawrence River. It is used to determine baseline status, long-term trends, spatial distributions, and the effectiveness of management actions.
Looped Spacetime Cosmology explores a compact S3×S1 topology linking black hole interiors and the Big Bang. The 284.9 KB PDF, authored by Richard T. Logue and last updated in May 2026, presents this framework as a falsifiable hypothesis. Its empirical program includes hierarchical tests using spatial curvature constraints and cosmic microwave background data.
Geoscience Australia Data studied the effect of sewage-derived nutrient loads on biogeochemical processes in three macrotidal, mangrove-lined creeks in Darwin Harbour, Australia. Water quality, sediment composition, benthic and pelagic metabolism, and nutrient fluxes were measured during three field surveys to compare nutrient transformation and retention. The study identified pelagic primary production, benthic nutrient fluxes, and denitrification efficiency as the processes most affected by nutrient loading.
Ondrej Hajdusek's research paper establishes chitin synthases as essential regulators of tick physiology. The 2.8 MB PDF details RNA interference-mediated silencing of three CHS genes, which impaired feeding, survival, and reproduction in the Lyme disease vector. Findings highlight CHSs as potential molecular targets for tick control strategies.
Ondrej Hajdusek's dataset on figshare contains experimental results from a study of chitin synthases (CHSs) in the tick Ixodes ricinus. The data likely includes measurements of chitin deposition, feeding success, survival, molting, oviposition, and pathogen acquisition after CHS gene silencing or etoxazole exposure. The dataset was last updated on May 15, 2026.
A 20.0 KB dataset from figshare, authored by Ondrej Hajdusek and last updated on 2026-05-15. It likely contains results from RNA interference experiments targeting chitin synthase genes in the tick Ixodes ricinus, a vector for Lyme borreliosis.
191 extragalactic sources detected by the Atacama Cosmology Telescope at 148 and/or 218 GHz in the 2008 Southern survey. Flux densities span 14 to 1700 mJy, with the catalog dividing sources into 167 radio galaxies and 24 dusty star-forming galaxies. The table was created by NASA's HEASARC in May 2015 based on a CDS catalog.
A 1.1 deg² region near the South Ecliptic Pole was surveyed at 20 cm wavelength using the Australia Telescope Compact Array. The catalog contains 530 radio sources detected with a resolution of 6.2 x 4.9 arcseconds, based on 170 hours of observations conducted in July 2007 and December 2008. The data were processed by NASA HEASARC in November 2013 from a published astronomical catalog.
The Atacama Cosmology Telescope 2008 Survey 148-GHz Extragalactic Source Catalog contains 157 radio sources detected in a 455 square-degree map of the southern sky. The catalog was created by NASA HEASARC in January 2011 based on data from the 2008 observing season. Flux densities for the sources range from 15 to 1500 mJy, and 98% of detections correspond to sources identified at lower radio frequencies.
85 radio sources detected in a 2009 deep survey covering 5 square degrees in the Chandra Deep Field South and SDSS Stripe 82. The catalog, created by NASA HEASARC in 2015, includes flux densities at 5.5, 9, 18, and 20 GHz, spectral indices, and notes on source variability over a 3-year period. The survey is estimated to be 90% complete above 2.5 mJy.
Geoscience Australia Data provides biostratigraphic data from the Challenger No. 1 well, offshore Perth Basin. The dataset contains Late Cretaceous to Palaeogene calcareous nannofossil assemblages used to revise the age of the Challenger Formation type section. It identifies three major disconformities and compares the section's completeness to nearby Deep Sea Drilling Project sites.
501 point sources identified across five frequency bands from 23 to 94 GHz, based on nine years of all-sky survey data from the Wilkinson Microwave Anisotropy Probe (WMAP) between August 10, 2001 and August 10, 2010. The catalog was produced by NASA using a five-band search technique that filters maps to suppress CMB and Galactic foreground fluctuations. The analysis covers 83% of the sky, an increase from 78% in the five-year version.
679 X-ray point sources were detected in a deep 70 ks Chandra observation of the Gum 31 HII region. The catalog, created by NASA HEASARC based on published research, includes basic X-ray properties and near- and mid-infrared photometry for identified counterparts. The observation aimed to characterize the young stellar population in a region with high galactic field-star contamination.
A catalog of 8,107 molecular clouds covering the Galactic plane within +/- 5 degrees latitude, derived from 20 years of CO line observations. The total H2 mass is 1.2 x 10^9 solar masses, with clouds showing a range of surface densities and systematic variations with Galactic radius. The HEASARC created this table in March 2019 based on data from Dame et al. (2001).
107 nearby galaxies comprise the main sample for investigating the relationship between X-ray emission and optical galaxy evolution. The catalog combines Chandra X-ray observations with Sloan Digital Sky Survey optical data to study low-luminosity active galactic nuclei. It provides X-ray spectral fits for sources with counts ranging from 2 to 1325, offering novel constraints on accretion power decline along an evolutionary sequence.
487 X-ray sources were detected in the XMM-Newton Slew Survey's hard 2-10 keV band at high galactic latitude. The HEASARC created this table in December 2012, which contains a defined sample of 219 galaxies and active galaxies from that survey. The authors note the survey reaches a flux sensitivity of roughly 3e-12 erg/cm²/s in the 2-10 keV band.
The Herschel Stripe 82 Survey (HerS) point source catalog contains 32,815 sources detected at 250 microns, with 13,300 and 3,276 sources at 350 and 500 microns, respectively. Observations were taken by the SPIRE instrument on the Herschel Space Observatory, covering 79 square degrees along the SDSS Stripe 82 region. The catalog was produced by the National Aeronautics and Space Administration to study correlations with the dark matter density field.
189 X-ray point sources detected in the barred spiral galaxy M 83 from three XMM-Newton observations. The catalog, created by NASA HEASARC in 2013, classifies sources including X-ray binaries, AGN candidates, and supernova remnants using spectral analysis and multi-wavelength cross-correlation. It includes derived X-ray luminosity functions for sources within and outside the galaxy's D25 ellipse.
