Canadian Telescope Can Detect Hydrogen From Early Universe: Study
The result used 94 clean days of data and showed hydrogen clumping in space, a key step toward measuring dark energy.
- On Monday, astronomers revealed detection of a hydrogen signal at approximately 8 billion light years from Earth using the Canadian Hydrogen Intensity Mapping Experiment , published in the Astrophysical Journal and marking the most distant such measurement.
- CHIME was designed to map cosmic hydrogen, but located in Penticton, B.C., the telescope faced a fundamental challenge: combined radio noise from the Milky Way is up to ten thousand times stronger than the faint hydrogen signal.
- Researchers analyzed data gathered over 2,000 days, refining it to just 94 days of ideal conditions, revealing that about two percent of the universe's hydrogen was in neutral atomic form roughly five billion years ago.
- The standalone detection offers a new method to gauge dark energy's influence on cosmic expansion. "This is a completely new technique for probing the cosmos," said Dr. Mark Halpern, CHIME principal investigator.
- Researchers will use this extended observational dataset to explore cosmic history further back in time, reaching as far as three billion years after the Big Bang to better understand the universe's evolution.
