City of Melbourne Open Data provides a false color aerial image mosaic of the municipal area captured on February 2-3, 2019. The 2GB TIF file, with a 5cm pixel size, uses an 11-band multispectral system to render intense red tones indicating vigorous, dense live vegetation.
A 2013 catalog from NASA HEASARC contains 230 X-ray sources detected in the giant elliptical galaxy NGC 1399. The data combines observations from the Chandra X-ray Observatory and the Hubble Space Telescope's Advanced Camera for Surveys. This study investigates the connection between globular clusters and low-mass X-ray binaries.
The Serendipitous Extragalactic X-Ray Source Identification (SEXSI) catalog contains 1,034 hard X-ray (2-10 keV) sources identified from over 2 square degrees of Chandra observations. It was created by NASA HEASARC in 2004 based on published research, providing a sample at intermediate fluxes (~10^-13 to 10^-15 erg/cm^2/s) to complement deeper, narrower surveys.
NASA HEASARC provides a catalog of observational properties for 722 dwarf nova-type and 309 other cataclysmic variables from the Catalina Real-time Transient Survey. The catalog includes apparent magnitudes, duty cycles, recurrence times, distance limits, orbital parameters, and X-ray counterparts, derived from long-term optical light curves and multi-catalog data. This is the largest sample of dwarf nova properties collected to date (2016).
A list of antisense oligonucleotides used in a specific study. The dataset likely contains details on chemical modifications, including backbone linkages and nucleotide substitutions. It was authored by Taylor L. Corridon and last updated on May 26, 2026.
1059 X-ray sources, including 318 newly detected ones, form this improved point-source catalog for the Extended Chandra Deep Field-South. The catalog was created by NASA HEASARC in 2016, implementing recent Chandra source-cataloguing improvements. It provides multi-wavelength identifications, counterpart magnitudes, redshifts, and source classifications for these generally fainter and more obscured objects.
A pharmacovigilance dataset by Hao Wen analyzes 41,775 reports from the FDA Adverse Event Reporting System (FAERS) from 2004 to 2024. It identifies significant statistical signals for 50 medications associated with cognitive disorders using four disproportionality analysis algorithms. The study includes cross-validation with Japanese and WHO adverse event databases.
41,775 adverse event reports from the FDA Adverse Event Reporting System (FAERS) were analyzed for signals of drug-related cognitive disorders. The dataset, created by Hao Wen and updated in April 2026, identifies 50 medications with significant statistical associations. Cross-validation was performed using Japanese and WHO pharmacovigilance databases.
41,775 adverse event reports from the FDA Adverse Event Reporting System (FAERS) were analyzed to identify signals for drug-related cognitive disorders. The study employed four disproportionality analysis algorithms and validated results across Japanese and WHO databases. Hao Wen published the findings in 2026, highlighting that 74% of flagged drugs lacked FDA label warnings.

Hao Wen conducted a disproportionality analysis using four algorithms and cross-database validation with JADER and WHO VigiAccess. The study identified 50 medications with significant signals, with 74% lacking FDA label warnings.
A research study analyzing nannofossil and planktic foraminiferal evidence to delineate the Oligocene-Miocene boundary in the Indo-Pacific region. The dataset, hosted by the Australian Ocean Data Network, was last updated in May 2026. It discusses biostratigraphic events like the appearances of Globigerinoides quadrilobatus primordius and Sphenolithus species across shallow and deep marine sediments.
9,017 X-ray point sources were identified in Chandra ACIS-I observations totaling 2.25 Ms of exposure around the Galactic center, doubling the known sources in the region. The catalog, created by NASA HEASARC in 2009, includes sources detected as of August 2007, with 60% having positions accurate to <1 arcsecond. It is designed to be inclusive, containing sources of varying quality, including 134 with net counts consistent with zero at 90% confidence.
168,941 astronomical objects, including 133,336 quasars, 1,374 BL Lac objects, and 34,231 active galaxies, comprise the 13th edition of the Veron-Cetty and Veron catalog. The NASA HEASARC created this online version in April 2010 based on tables from the CDS, with a last update in June 2012. It contains positions, redshifts, photometry (U, B, V), and radio flux densities for objects with measured redshifts known prior to July 1, 2009.
123 Fanaroff and Riley class II radio galaxies (FR IIs) selected from combined NVSS, FIRST, and SDSS survey observations. The catalog, published by NASA, includes sources with redshift <=0.15 and radio luminosity at 1.4 GHz ranging from ~10^39.5 to 10^42.5 erg/s. It distinguishes between low- and high-excitation galaxies (LEGs and HEGs), which show significant differences in host galaxy and black hole properties.
1005 quasars with unusual spectra were selected from the Sloan Digital Sky Survey Data Release 7 using Kohonen self-organising maps. The catalog, created by NASA HEASARC in May 2012, groups spectra into seven types dominated by broad absorption lines, unusual red continua, weak emission lines, or strong iron emission. Redshifts range from 0.497 to 4.771.
290 hard X-ray-selected sources from the SEXSI program with matched mid-infrared photometry from Spitzer IRAC and MIPS observations. The catalog was created by NASA HEASARC in March 2012 based on published research comparing AGN selection methods across X-ray and infrared wavelengths. The data originates from six fields with deep Chandra X-ray images, optical imaging, and extensive optical spectroscopy.
267 X-ray sources detected by the Chandra observatory across five fields, focusing on an intermediate flux range (10^-15 to 10^-12 ergs/s). The catalog includes deep V and I band optical images, X-ray-to-optical flux ratios, and optical spectroscopy identifications with redshifts for 106 sources. This table was created by NASA's HEASARC in March 2007 based on published astronomical data.
1103 blue stellar objects were identified from low-dispersion spectroscopic plates in the First Byurakan Survey. The catalog was compiled and revised by the author, cross-correlated with multiple optical and multi-wavelength catalogs like SDSS and 2MASS, and published via NASA HEASARC in October 2008. It supersedes a previous 1999 edition and includes updated SIMBAD and NED data, DSS positions, and refined spectral classifications.
