Published A mysterious object is being dragged into the supermassive black hole at the Milky Way's center
(via sciencedaily.com) An object near the supermassive black hole at the center of the Milky Way galaxy has drawn the interest of scientists because it has evolved dramatically in a relatively short time. A new study suggests that the object, called X7, could be a cloud of dust and gas that was created when two stars collided. The researchers believe it will eventually be drawn toward the black hole and will disintegrate.
Published New discovery sheds light on very early supermassive black holes
(via sciencedaily.com) Astronomers have discovered a rapidly growing black hole in one of the most extreme galaxies known in the very early Universe. The discovery of the galaxy and the black hole at its center provides new clues on the formation of the very first supermassive black holes.
Published Unusual atom helps in search for Universe's building blocks
(via sciencedaily.com) An unusual form of caesium atom is helping a research team unmask unknown particles that make up the Universe.
Published Discovery of massive early galaxies defies prior understanding of the universe
(via sciencedaily.com) Six massive galaxies discovered in the early universe are upending what scientists previously understood about the origins of galaxies in the universe.
Published Heterostructures support predictions of counterpropagating charged edge modes at the v=2/3 fractional quantum Hall state
(via sciencedaily.com) Original source Researchers have tested models of edge conduction with a device built on top of the semiconductor heterostructure which consists of gold gates that come close together. Voltage is applied on the gates to direct the edge states through the middle of the point contact, where they are close enough that quantum tunneling can occur between the edge states on opposite sides the sample. Changes in the electrical current flowing through the device are used to test the theorists' predictions.
Published Let there be (controlled) light
(via sciencedaily.com) In the very near future, quantum computers are expected to revolutionize the way we compute, with new approaches to database searches, AI systems, simulations and more. But to achieve such novel quantum technology applications, photonic integrated circuits which can effectively control photonic quantum states -- the so-called qubits -- are needed. Physicists have made a breakthrough in this effort: for the first time, they demonstrated the controlled creation of single-photon emitters in silicon at the nanoscale.
Published Theory can sort order from chaos in complex quantum systems
(via sciencedaily.com) Theoretical chemists have developed a theory that can predict the threshold at which quantum dynamics switches from 'orderly' to 'random,' as shown through research using large-scale computations on photosynthesis models.
Published The quantum twisting microscope: A new lens on quantum materials
(via sciencedaily.com) One of the striking aspects of the quantum world is that a particle, say, an electron, is also a wave, meaning that it exists in many places at the same time. Researchers make use of this property to develop a new type of tool -- the quantum twisting microscope (QTM) -- that can create novel quantum materials while simultaneously gazing into the most fundamental quantum nature of their electrons.
Published Physicists give the first law of thermodynamics a makeover
(via sciencedaily.com) Physicists at West Virginia University have made a breakthrough on an age-old limitation of the first law of thermodynamics.
Published 'Forbidden' planet orbiting small star challenges gas giant formation theories
(via sciencedaily.com) Astronomers have discovered an unusual planetary system in which a large gas giant planet orbits a small red dwarf star called TOI-5205. Their findings challenge long-held ideas about planet formation.
Published Researchers discover mysterious source of 'heartbeat-like' radio bursts in a solar fare
(via sciencedaily.com) A solar radio burst with a signal pattern, akin to that of a heartbeat, has been pinpointed in the Sun's atmosphere, according to a new study. An international team of researchers has reported uncovering the source location of a radio signal coming from within a C-class solar flare more than 5,000 kilometers above the Sun's surface.
Published Improving the performance of satellites in low Earth orbit
(via sciencedaily.com) On-chip distributed radiation sensors and current-sharing techniques can be used to reduce the impact of radiation on the radio and power consumption of small satellites, respectively. New findings can be used to make small satellites more robust, which can increase the connectivity of networks across the globe.
Published Physicists create new model of ringing black holes
(via sciencedaily.com) Original source A new analysis has modeled black hole collisions in more detail and revealed so-called nonlinear effects within gravitational waves. Nonlinear effects happen 'when waves on the beach crest and crash.'
Published Astrophysics: Scientists observe high-speed star formation
(via sciencedaily.com) Original source New observations have brought to light that stars can form through the dynamic interaction of gas within interstellar gas clouds. This process unfolds faster than previously assumed, research within the FEEDBACK programme on board the flying observatory SOFIA revealed.
Published New quantum sensing technique reveals magnetic connections
(via sciencedaily.com) A research team demonstrates a new way to use quantum sensors to tease out relationships between microscopic magnetic fields.
Published Tadpole playing around black hole
(via sciencedaily.com) Original source A peculiar cloud of gas, nicknamed the Tadpole due to its shape, appears to be revolving around a space devoid of any bright objects. This suggests that the Tadpole is orbiting a dark object, most likely a black hole 100,000 times more massive than the Sun. Future observations will help determine what is responsible for the shape and motion of the Tadpole.
Published Does ice in the Universe contain the molecules making up the building blocks of life in planetary systems?
(via sciencedaily.com) Original source If you want to build a habitable planet, ice is a key ingredient. The ice can be found in enormous clouds in the Universe and it is the main carrier of the necessary elements such as carbon, hydrogen, oxygen, nitrogen and sulphur. These elements are part of the atmosphere around planets and part of molecules like sugar, alcohols and simple amino acids as well. The new James Webb Space Telescope (JWST) has contributed to the discovery of different ices in a molecular cloud, 'Chameleon 1' -- one of the coldest and darkest regions to have ever been explored. Astronomers assume that these types of molecules were also present in the cold cloud of gas and dust forming our own solar system.
Published A star is born: Nearby galaxies provide clues about star formation
(via sciencedaily.com) Researchers have released their findings on polycyclic aromatic hydrocarbons in the interstellar medium of nearby galaxies.
Published Engineers discover a new way to control atomic nuclei as 'qubits'
(via sciencedaily.com) Researchers propose a new approach to making qubits, the basic units in quantum computing, and controlling them to read and write data. The method is based on measuring and controlling the spins of atomic nuclei, using beams of light from two lasers of slightly different colors.
