Researchers have found a new approach to probing the dynamics of the early universe using gravitational waves

Researchers have discovered a new general production mechanism for gravitational waves generated by a phenomenon known as oscillations, which can originate in many cosmological theories from the fragmentation into solitonian “clumps” of the inflaton field that drove the rapid expansion of the early universe, according to a new study published in the journal Science. Physical review letters on May 2.

The results paved the way for exciting new insights into beingThe first moments.

The period of inflation, which occurred just after the Big Bang, is thought to have caused the universe to expand exponentially. In many cosmological theories, a period of rapid expansion follows the formation of vibrations.

Oscilloscopes are a type of massive local nonlinear structure that can be formed by fields, such as an inflaton field, that oscillate at high frequencies. These structures can persist for long periods, and as the researchers found, their eventual decay can generate a significant amount of erosion gravitational waveswhich are ripples in space-time.

In their study, Kavli Institute for Physics and Mathematics of the Universe (Kavli IPMU) project researcher Kaloyan D. Lozanov, and Visiting Associate Scientist at the Kavli Institute IPMU, International Center for Quantum Field Measurement Systems for Universe and Particle Studies (QUP) Senior Scientist, Assistant Professor at the High Energy Acceleration Research Organization (KEK), Associate Professor at The Theory Center Volodymyr Takestov Simulated the evolution of a blown field air through early universe And I found that the oscillations were really there. Then they found that the decay of the oscillations was able to generate gravitational waves that could be detected by incoming gravitational wave observatories.

The results provide a new test of the dynamics of the early universe independently of the conventionally studied cosmic microwave background radiation. The discovery of these gravitational waves would open a new window on the very first moments of the universe, and could help shed light on some pressing fundamental questions in cosmology.

With the continued development of gravitational-wave detectors and supercomputing resources, we can expect to gain more insights into the very first moments of the universe in the coming years. Overall, the new study demonstrates the power of summation theoretical models With advanced computational techniques and observations to reveal new insights into the evolution of the universe.
