- It’s an acronym for Targeting Extremely Magnified Panchromatic Lensed Arcs and Their Extended Star Formation.
- Using NASA’s James Webb Space Telescope as a sort of time machine, a team of researchers intends to look billions of years into the past.
- The four galaxies will be studied under this programme. The gravitational lenses to study how those galaxies are forming their stars, and how that star formation is distributed across the galaxies.
- These four galaxies were chosen is because they’re very bright, making them easy to study. Two of the galaxies are very dusty, and two of them are not dusty at all.
- The two dusty galaxies are each lensed by another, single galaxy. The two galaxies that are not very dusty are lensed by galaxy clusters.
- These large celestial objects will magnify the light from distant galaxies that are at or near the peak of star formation.
- The phenomenon of gravitational lensing occurs when a huge amount of matter, such as a massive galaxy or cluster of galaxies, creates a gravitational field that distorts and magnifies the light from objects behind it, but in the same line of sight.
- The TEMPLATES team will use three of the four instruments aboard Webb, as well as many of the telescope’s filters and settings, to get as much data as possible on these galaxies.
The TEMPLATES team has four main goals:
- Measure how many new stars are forming, to determine how rapidly galaxies form stars
- Map the star-formation rate in these galaxies.
- Compare the young and old stellar populations
- Measure the conditions of the gas within these galaxies
