Exploring the Cosmos with the Alfonso Serrano Large Millimeter Telescope
Mexico is home to a groundbreaking astronomical tool, the Alfonso Serrano Large Millimeter Telescope (LMT). This joint US-Mexico radio telescope is the world’s largest single-aperture telescope in its frequency range, allowing scientists to study galaxies and the universe in unprecedented detail.
The telescope is situated in the Pico de Orizaba National Park on the top of the extinct Sierra Negra volcano, the fifth highest peak in Mexico, at an altitude of 4,580 meters above sea level. This location provides ideal atmospheric conditions for millimeter wave observations, making it an essential tool for scientists to explore the universe.
CONTRIBUTIONS TO ASTRONOMY
The LMT has made significant contributions to the field of astronomy, including the study of the formation and evolution of planetary systems, stars, black holes, and galaxies. Its high-altitude location and large primary reflector make it an essential tool for scientists, allowing them to capture data that has contributed to historic feats such as the first image of the shadow of a black hole.
TECHNICAL SPECIFICATIONS
The LMT features a 50 m diameter primary reflector, making it the world’s largest single-dish radio telescope that operates at millimeter wavelengths. Its redshift search receiver can cover the entire atmospheric window simultaneously, and its 16-pixel focal plane cryogenic spectral imaging system allows for high-resolution spectra of multiple lines.
The telescope’s 1 mm EHT receiver was initially designed for the Event Horizon Telescope experiment and can produce high-resolution spectra of multiple lines. Its bolometer camera, TOLTEC, features 7000 pixels and can produce diffraction-limited images of the sky in three different bands.
STUDYING GALAXIES
The LMT is designed and optimized for millimeter band observations, making it an ideal tool for studying galaxies and the formation of stars, planets, and galaxies. Its location in Sierra Negra provides a dry and transparent atmosphere that favors the reception of millimeter radiation.
With its advanced camera, TOLTEC, the telescope will be able to observe three color bands simultaneously and measure magnetic field structures. This will allow scientists to study star formation in our galaxy and in the early universe, providing valuable insights into the mysteries of the cosmos.
