Deflagration-to-Detonation Transition (DDT) process is the most common technique for obtaining stable detonation propagation. Although the detonation initiation appearances are different, the essential physical characteristic is the same: the local hot spot created by the energy focus. One or more bow shocks created by Mach reflection remain as strong transverse shocks after the detonation front. The corresponding numerical simulations show that the strong transverse shock propagation behavior strongly depends on the location where the hot spot forms. This work provides some fresh new insights into the DDT process, which may improve the understanding of DDT formation mechanisms.
Swansea University, Novel Engineering Consultants Ltd (Novel), and Airbus Endeavr Wales—a unique initiative between the Welsh Government and Airbus Defence and Space—are collaborating on a groundbreaking research initiative to strengthen aerospace systems against cyberattacks.
In an era of growing demand for real-time precision navigation, researchers have unveiled a powerful leap forward in satellite-based positioning.
A team of Italian researchers has uncovered compelling evidence of anomalous radioactive decay in cobalt-57 (Co-57) under ultrasonic stimulation, offering strong experimental support for the Deformed Space-Time (DST) theory. The findings, published by Stefano Bellucci (INFN-Frascati) and Fabio Cardone (ISMN-CNR), suggest that brief ultrasonic exposure can trigger a departure from conventional exponential decay laws, mediated by energy-dependent space-time distortions that violate local Lorentz invariance (LLI).
A fascinating glimpse into how a solar system like our own is born has been revealed with the detection of planet-forming ‘pebbles’ around two young stars. These seeds to make new worlds are thought to gradually clump together over time, in much the same way Jupiter was first created 4.5 billion years ago, followed by Saturn, Uranus, Neptune, Mercury, Venus, Earth and Mars. The planet-forming discs, known as protoplanetary discs, were spotted out to at least Neptune-like orbits around the young stars DG Tau and HL Tau, both around 450 light-years from Earth. The new observations, revealed at the Royal Astronomical Society’s National Astronomy Meeting 2025 in Durham, are helping to fill in a missing piece of the planet formation puzzle.
Celestial objects known as dark dwarfs may be hiding at the centre of our galaxy and could offer key clues to uncover the nature of one of the most mysterious and fundamental phenomena in contemporary cosmology: dark matter. A new paper published in the Journal of Cosmology and Astroparticle Physics (JCAP) by a team of researchers based in the UK and Hawaii describes these objects for the first time and proposes how to verify their existence using current observational tools such as the James Webb Space Telescope.
