The powerful CHIME (Canadian Hydrogen Intensity Mapping Experiment) radio telescope installed in British Columbia, Canada has intercepted 535 new fast radio bursts or FRBs. These mysterious radio signals lasting a few milliseconds have extremely high energy and can interact with hundreds of millions of dollars. Time alone. So far, the origin of these phenomena is not clear, and some of them are repetitive.
From 2007 Scientists have begun to pick up gods Strange signs In deep space, rapid radio bursts (FRB) Oh Fast radio flash. These mysterious phenomena occur in the radio frequency band Electromagnetic spectrum And produce a very powerful “flash” within a few milliseconds; the energy released by FRB is actually huge, equivalent to the energy emitted at the same time Hundreds of millions of suns. So far, people think they are relatively rare phenomenon, because the number of capture is very small (about 140), but, due to complex Radio telescope In British Columbia, Canada, this number has almost quadrupled. In fact, the scientists just announced that chimes (Canadian Hydrogen Intensity Mapping Experiment) Intercepted wells during 2018-2019 535 new fast radio bursts, In the first year of its activities.
“Before CHIME, a total of less than 100 FRBs were discovered; now, after a year of observation, we have discovered hundreds more,” he said in an interview. Press release The scientist involved in the project, Dr. Kaitlyn Shin, graduated from the prestigious Massachusetts Institute of Technology (MIT) Department of Physics. “With all these sources, we can really begin to understand the overall situation of FRB, how astrophysics triggers these events, and how they can be used to study the universe in the future,” she added.
There are two different types of FRB: most are single, That is, it only appears once at a certain point in space, it is no longer interceptable, and a small part Repeat yourself With variable frequency.This pattern is also reflected in the hundreds of new radio signals intercepted by CHIME; in fact, out of 535, only 18 are duplicates. This is the first such type identified in 2012. Arecibo Telescope.
The origin of Lampi Radio Veloci is still uncertain, but at least for Milky Way It is certain: it is a Magnetar, A Neutron Star Very powerful magnetic field, Billions of times higher than the energy of the earth. Thanks to CHIME’s multiple investigations, it will be possible to better determine the most elusive origin. To be sure, according to the distribution in the sky, scholars believe that these phenomena are not uncommon, and it is estimated that there are 9,000 signals per day. The CHIME who hunted them processed 7 terabytes of data per second. Thanks to the research on FRB, scientists will be able to obtain more information about the distribution of FRB. gas electronic thing In space, it also laid the foundation for new cosmological research.The details of the study were presented during the 238th meeting American Astronomical Society.
