A.
Two Micron All Sky Survey
chosen
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.
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.
-
C.
Photometria
Photometria is an influential 1760 treatise by Johann Heinrich Lambert that laid the foundations of photometry by quantitatively describing the measurement and behavior of light.
-
D.
VISTA telescope
The VISTA telescope is a 4.1-meter wide-field survey telescope in Chile designed primarily for large-scale near-infrared sky surveys.
