The Galaxy Evolution Explorer : A Space Ultraviolet Survey Mission
Open accessAbstract
We give an overview of the Galaxy Evolution Explorer ( GALEX ), a NASA Explorer Mission launched on 2003 April 28. GALEX is performing the first space UV sky survey, including imaging and grism surveys in two bands (1350-1750 and 1750-2750 Å). The surveys include an all-sky imaging survey ( m AB ≃ 20.5), a medium imaging survey of 1000 deg 2 ( m AB ≃ 23), a deep imaging survey of 100 deg 2 ( m AB ≃ 25), and a nearby galaxy survey. Spectroscopic (slitless) grism surveys ( R = 100-200) are underway with various depths and sky coverage. Many targets overlap existing or planned surveys in other bands. We will use the measured UV properties of local galaxies, along with corollary observations, to calibrate the relationship of the UV and global star formation rate in local galaxies. We will apply this calibration to distant galaxies discovered in the deep imaging and spectroscopic surveys to map the history of star formation in the universe over the redshift range 0 < z < 2 and probe the physical drivers of star formation in galaxies. The GALEX mission includes a guest investigator program, supporting the wide variety of programs made possible by the first UV sky survey.

Scaling the SFR from the combined footprint by the fraction of the galaxy's FUV D25 flux enclosed within the footprint implies a total disk-averaged SFR of about 0.67 M⊙ yr^-1 over the last 100 Myr.
“Scaling the SFR from the combined footprint by the fraction of the galaxy's FUV D25 flux (obtained from Martin et al. 2005) enclosed within the footprint implies a total disk-averaged SFR of ∼ 0 . 67 M ⊙ yr -1 over the last 100 Myr.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
