Published Characterizing the earliest galaxies in the universe -- only 200 million years after the Big Bang
(via sciencedaily.com) An international team of astrophysicists has managed to statistically characterize the first galaxies in the Universe, which formed only 200 million years after the Big Bang.
Published New analysis approach could help boost sensitivity of large telescopes
(via sciencedaily.com) Researchers detail an analysis method that could improve telescopes at the Simons Observatory by evaluating their performance before installation. This is the first time the optical performance of a telescope has been confirmed prior to its deployment.
Published 'Digital footprints' central to new approach for studying post-disturbance recreation changes
(via sciencedaily.com) A new social media-based study of recreation visitation in the Gorge following the Eagle Creek Fire expands on research launched in 2016 -- and holds promise for other large, multi-ownership landscapes. The study shows how using new approaches that draw from social media data can help us better understand the complex relationships between wildfire, natural resource management, and people.
Published Rare sighting of luminous jet spewed by supermassive black hole
(via sciencedaily.com) Astronomers discover a bright optical flare caused by a dying star's encounter with a supermassive black hole.
Published Mysteriously bright flash is a black hole jet pointing straight toward Earth, astronomers say
(via sciencedaily.com) Astronomers have determined the source of an incredibly bright X-ray, optical and radio signal appearing from halfway across the Universe.
Published Major fires an increasing risk as the air gets thirstier, research shows
(via sciencedaily.com) Greater atmospheric demand for water means a dramatic increase in the risk of major fires in global forests unless we take urgent and effective climate action, new research finds. Researchers have examined global climate and fire records in all of the world's forests over the last 20 years.
Published Non-detection of key signal allows astronomers to determine what the first galaxies were -- and weren't -- like
(via sciencedaily.com) Researchers have been able to make some key determinations about the first galaxies to exist, in one of the first astrophysical studies of the period in the early Universe when the first stars and galaxies formed, known as the cosmic dawn.
Published When cyclones and fires collide...
(via sciencedaily.com) As strong winds and torrential rains inundate Australia's south-eastern coast, new research suggests that high intensity bushfires might not be too far behind, with their dual effects extending damage zones and encroaching on previously low-risk residential areas.
Published Astrophysicists hunt for second-closest supermassive black hole
(via sciencedaily.com) As massive as the black hole at the center of the Milky Way, the behemoth is hosted by a dwarf galaxy less than 1 million light-years away. Invisible so far -- maybe not for long.
Published Astronomers observe intra-group light -- the elusive glow between distant galaxies
(via sciencedaily.com) Pioneering a new technique, researchers have peered into the extremely faint light that exists between galaxies to describe the history and state of orphan stars.
Published International team observes innermost structure of quasar jet
(via sciencedaily.com) Scientists have observed the narrowing of a quasar jet for the first time by using a network of radio telescopes across the world. The results suggest that the narrowing of the jet is independent of the activity level of the galaxy which launched it.
Published An exoplanet atmosphere as never seen before
(via sciencedaily.com) New observations of WASP-39 b reveal a never-before-seen molecule in the atmosphere of a planet -- sulfur dioxide -- among other details.
Published Short gamma-ray bursts traced farther into distant universe
(via sciencedaily.com) Astronomers have developed the most extensive inventory to date of the galaxies where short gamma-ray bursts (SGRBs) originate. Using several highly sensitive instruments and sophisticated galaxy modeling, the researchers pinpointed the galactic homes of 84 SGRBs and probed the characteristics of 69 of the identified host galaxies.
Published The tilt in our stars: The shape of the Milky Way's halo of stars is realized
(via sciencedaily.com) New data throws out the textbook picture of a spherical stellar halo and reinforces a dynamic origin story of two galaxies that collided billions of years ago.
Published Black holes in eccentric orbit
(via sciencedaily.com) A research team has reconstructed the origin of an unusual gravitational wave signal. The signal GW190521 may result from the merger of two massive black holes that captured each other in their gravitational field and then collided while spinning around each other in a rapid, eccentric motion.
Published Elusive, dusty inner region of distant galaxy
(via sciencedaily.com) An international team of scientists has achieved the milestone of directly observing the long-sought, innermost dusty ring around a supermassive black hole, at a right angle to its emerging jet. Such a structure was thought to exist in the nucleus of galaxies but had been difficult to observe directly because intervening material obscured our line of sight.
Published NASA's Webb catches fiery hourglass as new star forms
(via sciencedaily.com) NASA's James Webb Space Telescope has revealed the once-hidden features of the protostar within the dark cloud L1527, providing insight into the beginnings of a new star. These blazing clouds within the Taurus star-forming region are only visible in infrared light, making it an ideal target for Webb's Near-Infrared Camera (NIRCam).
Published NASA's Webb draws back curtain on universe's early galaxies
(via sciencedaily.com) A few days after officially starting science operations, NASA's James Webb Space Telescope propelled astronomers into a realm of early galaxies, previously hidden beyond the grasp of all other telescopes until now.
Published How does radiation travel through dense plasma?
(via sciencedaily.com) Researchers provide experimental data about how radiation travels through dense plasmas. Their data will improve plasma models, which allow scientists to better understand the evolution of stars and may aid in the realization of controlled nuclear fusion as an alternative energy source.
Published WALLABY builds an intergalactic map in the outback
(via sciencedaily.com) A radio telescope in remote Western Australia is helping to build a 3-dimensional map of the night sky, mapping nearby galaxies up to a billion light years away.
