Astronomical Surveys and Big Data
  Recent all-sky and large-area astronomical surveys and their catalogued data
over the whole range of electromagnetic spectrum are reviewed, from Gamma-ray
to radio, such as Fermi-GLAST and INTEGRAL in Gamma-ray, ROSAT, XMM and Chandra
in X-ray, GALEX in UV, SDSS and several POSS I and II based catalogues (APM,
MAPS, USNO, GSC) in optical range, 2MASS in NIR, WISE and AKARI IRC in MIR,
IRAS and AKARI FIS in FIR, NVSS and FIRST in radio and many others, as well as
most important surveys giving optical images (DSS I and II, SDSS, etc.), proper
motions (Tycho, USNO, Gaia), variability (GCVS, NSVS, ASAS, Catalina,
Pan-STARRS) and spectroscopic data (FBS, SBS, Case, HQS, HES, SDSS, CALIFA,
GAMA). An overall understanding of the coverage along the whole wavelength
range and comparisons between various surveys are given: galaxy redshift
surveys, QSO/AGN, radio, Galactic structure, and Dark Energy surveys. Astronomy
has entered the Big Data era. Astrophysical Virtual Observatories and
Computational Astrophysics play an important role in using and analysis of big
data for new discoveries.
