## Telescope Details

Website

#### **Location:**

Sierra Negra, Mexico

#### **Purpose:**

TolTEC will study the universe on nearly all scales, from large-scale structure of matter in the early universe to individual cores of star formation. 

#### **NIST’s role:**

Led development of the TolTEC camera, which offers high sensitivity and mapping speeds in three colors. The use of multiple colors helps distinguish real signals from interfering noise. 

#### **Significant discoveries:**

TolTEC installation was delayed due to the pandemic, but pieces are now being sent to the site. 

#### **Other interesting facts:**

TolTEC is projected to offer 100 times the mapping speed of its predecessor camera. The telescope is situated on a mountain peak at an elevation of 4,572 meters (15,000 feet), providing excellent observing conditions.

#### **Supported by:**

National Science Foundation

#### **Developed by:**

A collaboration of seven institutions in three countries: NIST, Arizona State University, Northwestern University, University of Michigan, Cardiff University, the Instituto Nacional de Astrofísica, and Óptica y Electrónica

#### **Operated by:**

Instituto Nacional de Astrofísica, Óptica y Electrónica and University of Massachusetts at Amherst
