A. Two Micron All Sky Survey
The Two Micron All Sky Survey (2MASS) is an astronomical survey that mapped the entire sky in near-infrared wavelengths, producing a comprehensive catalog of stars, galaxies, and other celestial objects.
B. Sloan Digital Sky Survey
The Sloan Digital Sky Survey is a major astronomical project that has created some of the most detailed three-dimensional maps of the universe using wide-field imaging and spectroscopy.
C. Carnegie-Spitzer-IMACS Survey
The Carnegie-Spitzer-IMACS Survey is an astronomical research project that combines infrared observations from the Spitzer Space Telescope with optical spectroscopy from the IMACS instrument to study the formation and evolution of galaxies across cosmic time.
D. Palomar Transient Factory
The Palomar Transient Factory is an astronomical survey project that used the Palomar Observatory to systematically search the night sky for transient and variable phenomena such as supernovae and other short-lived cosmic events.
