New Study Reveals Supermassive Black Holes' Role in Galaxy Evolution
A groundbreaking study has shed new light on the evolution of galaxies, revealing the crucial role of supermassive black holes and the impact of a new deep learning method on our understanding of the cosmos.
The 'pop-cosmos' model, developed by a team led by Sinan Deger, Hiranya V. Peiris, and Stephen Thorp, has mapped the star formation history of 420,000 galaxies over the last 12 billion years. This generative model has significantly improved measurements of dark energy, dark matter, and neutrino masses by analyzing the cosmic microwave background (CMB).
The study found that lower-mass galaxies maintain a consistent star formation rate over time, while more massive galaxies experience a gradual decline lasting up to a billion years. A significant fraction of these larger galaxies continue to form stars recently. The model suggests that massive galaxies cease star formation over a few billion years, with supermassive black hole activity playing a key role in this process.
Observations of distant galaxies and quasar pairs about 12 billion light-years away confirm that supermassive black holes and their relativistic jets have been shaping galaxies since the early universe's history. These active galactic nuclei (AGN) regulate galaxy evolution by distributing energy and matter on cosmic scales.
The 'pop-cosmos' model has provided valuable insights into the evolution of galaxies, highlighting the influence of supermassive black holes and the impact of a new deep learning method on our understanding of the cosmos. Further research using this model is expected to enhance our knowledge of dark energy, dark matter, and neutrino masses.
