A number of science projects have been put forward in frame of ArVO and are currently under way:

•         FAUBOS (FBS/APS/USNO Blue Objects Survey): pre-selection by MAPS/USNO-B1.0 colors, study by the DFBS spectra and DSS1/DSS2 images; search for QSO/Sy & WD/sd/CV

•         EROS (Extremely Red Objects Spectra): FBS/2MASS/IRAS/MAPS/USNO-B1.0 cross-correlations and pre-selection; classification based on the DFBS low-dispersion spectra

•         VCV/MAPS/USNO-B1.0 cross-correlation: examination of the DSS1/DSS2 images of bright AGN from the Vιron-Cetty and Vιron (VCV) catalog and their re-classification by the extension, photometric data based on the classification, VCV statistical study

•         Multiwavelength bright AGN sample: VCV V<17.5^m objects cross-correlations with NVSS, FIRST, IRAS PSC/FSC, 2MASS, ROSAT BSC/FSC, DFBS, etc.: Complete sample of bright AGN over 10,000 deg2 area

•         Optical identifications of radio sources: NVSS/FIRST cross-correlation with MAPS/USNO (blue objects); DFBS spectra

•         Optical identifications of IR sources: IRAS PSC/FSC cross-correlation with 2MASS/MAPS/USNO-B1.0 (galaxies, red stars, etc.); DFBS spectra

•         Optical identifications of X-ray sources: ROSAT BSC/FSC cross-correlation with MAPS/USNO (blue objects, galaxies, red stars, etc.); DFBS spectra

ArVO is open for collaboration and proposals for new science projects are welcome.
