The quest to locate the missing material of the universe has been animating astronomers for decades. With only 15 % of visible ordinary material and the rest buried in invisible forms, scientists explored various hypotheses to fill this void. Recently, a significant advance has been carried out thanks to the detection of ionized hydrogen gas halos around galaxies. This discovery could revolutionize our understanding of ordinary matter in the universe and resolve one of the greatest mysteries of modern astronomy.
A major discovery thanks to the Sunyaev-Zel’dovich Cinematics effect
The Sunyaev-Zel’dovich Cinematics effect offers a unique window on the invisible universe. This phenomenon occurs when the photons of the microwave cosmic background interact with the electrons in ionized gas, generating subtle temperature variations. These variations make it possible to detect gas structures that escape conventional observation methods. Thanks to this technique, the researchers were able to map The distribution of gas around a million galaxies with unprecedented precision.
This approach revealed that the gas halos surrounding the galaxies are much more extensive than what had been estimated before. Using advanced instruments such as the Cosmological Telescope of Atacama, scientists were able to analyze the data collected. The results of this study are being published, promising to redefine our understanding of the universe.

The crucial role of supermassive black holes
THE Supermassive black holes play a surprising role in dispersion of gas around galaxies. Located in the heart of most galaxies, these cosmic objects can become extremely active, generating powerful particle jets and winds. This process, known as galactic feedback, expels gas far from the galactic center, thus regulating the formation of stars.
The new observations indicate that this feedback is more vigorous than expected, implying that black holes influence the evolution of galaxies at different stages of their existence. This intense activity could also affect the large -scale structure of the universe, requiring a revision of galaxy training models. Future simulations will have to integrate these new data to offer a more complete image of the universe.

International collaboration at the heart of discovery
This major advance would not have been possible without a collaboration internationale exceptional. Researchers from around the world have joined forces to use the data provided by instruments such as the Dark Energy Spectroscopic Instrument (DESI) and the Cosmological Telescope of Atacama. These tools have provided extremely precise measurements of the microwave cosmic background, essential for detecting invisible gas halos.
The cross -data analysis made it possible to validate the observations and to establish a detailed mapping of the distribution of gas. This cooperation demonstrates the importance of collective efforts in scientific research, opening the way to future discoveries that could transform our understanding of the universe.

Future prospects of cosmology
The discovery of ionized hydrogen hydrogen gas halos around galaxies has vast implications for cosmology. It resolves a major conflict between observations and theoretical models, showing that the missing material was at hand but in a difficult form to detect. This advance offers new perspectives for the study of the large -scale structure of the universe and could even shed light on our understanding of the fundamental laws of physics.
The next steps include In -depth analyzes and the use of simulations to refine the current results. The researchers also hope to take advantage of these techniques to probe the primordial universe, thus providing precious clues to the first phases of its evolution. How will these new discoveries redefine our vision of the universe in the years to come?
