The Galaxy Evolution Explorer (GALEX). Its legacy of UV surveys, and science highlights
The Galaxy Evolution Explorer (GALEX) imaged the sky in the Ultraviolet (UV) for almost a decade, delivering the first sky surveys at these wavelengths. Its database contains far-UV (FUV, λeff ∼ 1528Å) and near-UV (NUV, λeff ∼ 2310Å) images of most of the sky, including deep UV-mapping of extended galaxies, over 200 million source measurements, and more than 100,000 low-resolution UV spectra. T...
متن کاملThe Galex Uv Luminosity Function of the Cluster of Galaxies
We present the GALEX NUV (2310Å) and FUV (1530Å) galaxy luminosity functions of the nearby cluster of galaxies A1367 in the magnitude range−20.3 ≤ MAB ≤ −13.3. The luminosity functions are consistent with previous (∼ 2 mag shallower) estimates based on the FOCA and FAUST experiments, but display a steeper faint-end slope than the GALEX luminosity function for local field galaxies. Using spectro...
متن کاملRemoval of Dye and COD from Textile Wastewater Using AOP (UV/O3, UV/H2O2, O3/H2O2 and UV/H2O2/O3)
Introduction: Textile industry effluent is a complex sewage with chemical and color materials that is discharged into the environment and can cause serious problems. In this way using advanced oxidation methods and finding the best methods for removing color materials is necessary. An experimental method was done on Kashan textile industry effluent in laboratory scale and batch system. Materia...
متن کاملHydrogen Peroxide Photolysis with Different Uv Light Sources including a New Uv-led Light Source
Hydrogen peroxide 0.1% was photolyzed using 17W low pressure mercury arc lamp and 125 W high pressure mercury arc lamp. The decomposition kinetics was followed through the pseudofirst order kinetics and different conditions of temperature and pH were explored. H2O2 0.1% was also photolyzed at 360 nm through a new UV-LED 3W light source using a flow reactor. The kinetics rate constant achieved w...
متن کاملRemoval of Azithromycin from aqueous solution using UV- light alone and UV plus Persulfate (UV/Na2S2O8) processes
Introduction. Azithromycin is among the broad-spectrum antibiotics that is widely available in various environmental systems and could have destructive effects on the ecosystem and human health due to its bacterial resistance. In this study, removal of azithromycin from wastewater using an advanced oxidation process of ultraviolet light with and without persulfate was investigated and effective...
