A dataset from 2026 by Calum Fyfe investigating the limitations of 8-bit sRGB color encoding for chemical analysis. It contains spectroscopic color measurements for a series of common dyes and simulated time-series data showing how gamut clipping can distort chemical monitoring. The dataset is 278.5 MB and shared under a CC-BY-4.0 license.
May 25 to September 27, 1989 data from the Voyager 2 Planetary Radio Astronomy instrument during its Neptune encounter. The dataset contains high-rate frames, each 48 seconds long, with a 28-octet header and 1,280,000 octets of data per file. It was produced by the National Aeronautics and Space Administration.
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.
An analysis of harmonic phase relationships within the Planck 2018 Cosmic Microwave Background temperature and polarization power spectra over multipoles ℓ = 200–2000. The study, authored by Amy Condit of 22 Blue CMB Birefringence & Standing-Wave Rotation Field, identifies robust sinusoidal oscillations with a period of approximately Δℓ ≈ 320 in the TE and EE polarization spectra. It uses residuals relative to the baseline ΛCDM model, harmonic decomposition, and Monte Carlo validation to examine statistical organization.
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.
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 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.
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.
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.
John Kappel, Matt Landreman, Philipp Jurašić, and Sophia A. Henneberg authored this dataset exploring the relationship between magnetic gradient scale length and coil complexity in stellarators. The data includes analyses from the QUAsi-Symmetric Stellarator Repository and new optimizations of quasihelically symmetric equilibria and filament coils. It was last updated on June 23, 2026.
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.
MESA inlists associated with a study exploring stellar evolution models of subdwarf B stars. The data was created by Jan–Torge Schindler at the University of Arizona. The dataset's size and last update date are unknown.
Fortuitous observations of potential stellar relay probe positions were conducted using the Green Bank Telescope. The data table was produced by Michael L. Palumbo of Pennsylvania State University as part of the associated research. The record is available under an Open Access license.
Datasets from a publication by Hannah Thiel of Universität Innsbruck present simulations and measurements for loss analysis. The data supports the methodology described in 'A practical guide to loss measurements using the Fourier transform of the transmission spectrum'. Row counts, column details, and file formats are unspecified.
