Published NASA's Hubble hunts for intermediate-sized black hole close to home
(via sciencedaily.com) Original source Astronomers have come up with what they say is some of their best evidence yet for the presence of a rare class of 'intermediate-sized' black hole that may be lurking in the heart of the closest globular star cluster to Earth, located 6,000 light-years away.
Published Element creation in the lab deepens understanding of surface explosions on neutron stars
(via sciencedaily.com) Original source Scientists working in the lab have produced a signature nuclear reaction that occurs on the surface of a neutron star gobbling mass from a companion star. Their achievement improves understanding of stellar processes generating diverse nuclear isotopes.
Published Eruption of Tonga underwater volcano found to disrupt satellite signals halfway around the world
(via sciencedaily.com) Original source Researchers found that the Hunga-Tonga eruption was associated with the formation of an equatorial plasma bubble in the ionosphere, a phenomenon associated with disruption of satellite-based communications. Their findings also suggest that a long-held atmospheric model should be revised.
Published Stretching metals at the atomic level allows researchers to create important materials for quantum, electronic, and spintronic applications
(via sciencedaily.com) Original source A University of Minnesota Twin Cities-led team has developed a first-of-its-kind breakthrough method that makes it easier to create high-quality metal oxide films that are important for various next generation applications such as quantum computing and microelectronics.
Published An X-ray look at the heart of powerful quasars
(via sciencedaily.com) Original source Researchers have observed the X-ray emission of the most luminous quasar seen in the last 9 billion years of cosmic history, known as SMSS J114447.77-430859.3, or J1144 for short. The new perspective sheds light on the inner workings of quasars and how they interact with their environment.
Published Uncovering universal physics in the dynamics of a quantum system
(via sciencedaily.com) Original source New experiments using one-dimensional gases of ultra-cold atoms reveal a universality in how quantum systems composed of many particles change over time following a large influx of energy that throws the system out of equilibrium.
Published Curved spacetime in a quantum simulator
(via sciencedaily.com) Original source The connection between quantum physics and the theory of relativity is extremely hard to study. But now, scientists have set up a model system, which can help: Quantum particles can be tuned in such a way that the results can be translated into information about other systems, which are much harder to observe. This kind of 'quantum simulator' works very well and can lead to new insights about the nature of relativity and quantum physics.
Published Radio signal reveals supernova origin
(via sciencedaily.com) Original source Astronomers reveal the origin of a thermonuclear supernova explosion. Strong emission lines of helium and the first detection of such a supernova in radio waves show that the exploding white dwarf star had a helium-rich companion.
Published NASA's Spitzer, TESS find potentially volcano-covered Earth-size world
(via sciencedaily.com) Original source Astronomers have discovered an Earth-size exoplanet, or world beyond our solar system, that may be carpeted with volcanoes. Called LP 791-18 d, the planet could undergo volcanic outbursts as often as Jupiter's moon Io, the most volcanically active body in our solar system.
Published Astronomers observe the first radiation belt seen outside of our solar system
(via sciencedaily.com) Original source Astronomers have described the first radiation belt observed outside our solar system, using a coordinated array of 39 radio dishes from Hawaii to Germany to obtain high-resolution images. The images of persistent, intense radio emissions from an ultracool dwarf reveal the presence of a cloud of high-energy electrons trapped in the object's powerful magnetic field, forming a double-lobed structure analogous to radio images of Jupiter's radiation belts.
Published New study puts a definitive age on Saturn's rings -- they're really young
(via sciencedaily.com) Original source Physicists measured the flux of interplanetary dust around Saturn. The researchers concluded that the planet's rings formed less than 400 million years ago, making them much younger than Saturn itself.
Published Astronomers reveal the largest cosmic explosion ever seen
(via sciencedaily.com) Original source Astronomers have uncovered the largest cosmic explosion ever witnessed. The explosion is more than ten times brighter than any known supernova and three times brighter than the brightest tidal disruption event, where a star falls into a supermassive black hole.
Published Researchers find new approach to explore earliest universe dynamics with gravitational waves
(via sciencedaily.com) Original source Researchers have discovered a new generic production mechanism of gravitational waves generated by a phenomenon known as oscillons.
Published Hidden supermassive black holes brought to life by galaxies on collision course
(via sciencedaily.com) Original source Astronomers have found that supermassive black holes obscured by dust are more likely to grow and release tremendous amounts of energy when they are inside galaxies that are expected to collide with a neighbouring galaxy.
Published Celestial monsters at the origin of globular clusters
(via sciencedaily.com) Original source Globular clusters are the most massive and oldest star clusters in the Universe. They can contain up to 1 million of them. The chemical composition of these stars, born at the same time, shows anomalies that are not found in any other population of stars. Explaining this specificity is one of the great challenges of astronomy. After having imagined that supermassive stars could be at the origin, a team believes it has discovered the first chemical trace attesting to their presence in globular proto-clusters, born about 440 million years after the Big Bang.
Published Hidden views of vast stellar nurseries
(via sciencedaily.com) Original source Astronomers have created a vast infrared atlas of five nearby stellar nurseries by piecing together more than one million images. These large mosaics reveal young stars in the making, embedded in thick clouds of dust. Thanks to these observations, astronomers have a unique tool with which to decipher the complex puzzle of stellar birth.
Published With new experimental method, researchers probe spin structure in 2D materials for first time
(via sciencedaily.com) Original source In the study, a team of researchers describe what they believe to be the first measurement showing direct interaction between electrons spinning in a 2D material and photons coming from microwave radiation.
Published Researcher uses artificial intelligence to discover new materials for advanced computing
(via sciencedaily.com) Original source Researchers have identified novel van der Waals (vdW) magnets using cutting-edge tools in artificial intelligence (AI). In particular, the team identified transition metal halide vdW materials with large magnetic moments that are predicted to be chemically stable using semi-supervised learning. These two-dimensional (2D) vdW magnets have potential applications in data storage, spintronics, and even quantum computing.
Published Measurement of the Universe's expansion rate weighs in on a longstanding debate in physics and astronomy
(via sciencedaily.com) Original source A team used a first-of-its-kind technique to measure the expansion rate of the Universe, providing insight that could help more accurately determine the Universe's age and help physicists and astronomers better understand the cosmos.
Published Astronomers find no young binary stars near Milky Way's black hole
(via sciencedaily.com) Original source Scientists analyzed over a decade's worth of data about 16 young supermassive stars orbiting the supermassive black hole at the center of the Milky Way galaxy. Supermassive stars typically are formed in pairs, but the new study found that all 16 of the stars were singletons. The findings support a scenario in which the supermassive black hole drives nearby stars to either merge or be disrupted, with one of the pair being ejected from the system.
