University of Pennsylvania astrophysicist Licia Verde outlines a multi-disciplinary approach to studying dark energy. The investigation draws on data from galaxy surveys, supernovae, and the Cosmic Microwave Background, providing clues about this enigmatic component.
Researchers found that strong stellar winds around young red dwarfs may be responsible for removing dust and debris disks. The discovery provides a potential explanation for the rare occurrence of debris disks among red dwarfs, but further observations are needed to confirm this hypothesis.
A team of researchers uses the Keck laser system to observe distant galaxies in unprecedented detail, finding that some systems exhibit old stars despite recent mergers. This discovery challenges prevailing theories of galaxy formation and may help explain the existence of large galaxies with little young star population.
A Yale astronomer and her colleagues used gravitational lensing techniques to create a spatial map demonstrating the clumped substructure of dark matter inside galaxy clusters. The study found an excellent agreement between observations and theoretical predictions, supporting the concordance model.
Scientists have developed a new method to isolate the light from compact regions of black holes using polaroid filters. This allows them to focus on the area surrounding the black hole, revealing new signals such as the 'Balmer edge' feature that provides information about material properties.
The Gemini Observatory has released a breathtaking image of Stephan's Quintet, capturing the intricate interactions between five galaxies. The image showcases sweeping arches of gas and dust, tracing the ongoing dance of gravitational forces that have warped their structures over millions of years.
A recent study has revealed surprisingly mature galaxies in the early universe, contradicting the long-held hierarchical model of galaxy formation. The Gemini Deep Deep Survey found that a large fraction of stars in massive galaxies were already present at 8 billion years old.
A new theory by Jason Tumlinson and colleagues reconciles two conflicting pieces of evidence on the nature of the first stars. The theory suggests that these early stars were smaller than previously thought, with masses between 20-100 times that of the sun.
The CDMS II experiment has narrowed the search for WIMPs, a type of dark matter particle. The results show that the interaction rate of a WIMP with ordinary matter should be less than one interaction every 25 days per kilogram of germanium.
Researchers from Cardiff University suggest that a large comet impact could throw material containing micro-organisms out of the planet's atmosphere, infecting hundreds of millions of nascent planetary systems. This viable bacterial outflow would survive heat and radiation, ultimately spreading Earth-life across the galaxy.
Astronomers have discovered two unique rings of dust illuminated by the afterglow of a gamma-ray burst in our galaxy. The rings, caused by dust scattering X-rays from the burst, reveal new insights into the distribution and behavior of dust in the Galaxy.
The Gemini Deep Deep Survey has revealed a greater abundance of more massive and older galaxies than expected, dating back to the early universe. The discovery challenges current models of galaxy formation and suggests an accelerated growth phase for galaxies.
The STELLAR and MERCURY I studies show CRESTOR significantly improves key apolipoprotein and lipid ratios, including Apo B, Apo A-I, and the Apo B:Apo A-I ratio, in patients with hypercholesterolaemia. These findings support CRESTOR's benefits in reducing cardiovascular disease risk.
The team reconstructed a mass map of the galaxy cluster using NASA/ESA Hubble Space Telescope data, tracing dark matter's distribution with respect to galaxies. The study reveals that dark matter clumps together in certain regions, supporting the idea that clusters assemble through the merger of smaller groups.
A study published by the Mayo Clinic found that 55% of golfers with the 'yips' described physical symptoms, while only 22% attributed them to psychology. The research suggests a continuum of causes for the condition, including performance anxiety and focal dystonia.
Scientists have developed a new theory explaining the formation of large-scale magnetic fields in galaxies, which twist and expand like elastic ribbons. The theory resolves a long-standing problem in astrophysics by showing how turbulence creates opposing small-scale fields that eventually suppress growth.
Researchers using galaxy cluster surveys can measure the equation of state of dark energy, which would provide clues about its nature and origin. By studying scaling relations and X-ray emission, scientists hope to determine the essence of dark energy.
The DEIMOS instrument will multiply the power of current Keck spectroscopy by a factor of seven, enabling observations of distant galaxies and shedding light on the formation and evolution of galaxies. With its massive detector and advanced optics, DEIMOS will create the most comprehensive map of the distant universe ever attempted.
Astronomers have shed new light on dark matter distribution by tracing it closely to galaxy patterns. They found that dark matter is distributed in a parallel pattern to galaxies and makes up about seven times more mass than ordinary matter.
The Interplanetary Network detected a gigantic gamma-ray burst, the most distant ever observed, from a dying star 30 times more massive than the sun. The burst is believed to have occurred 11 billion years ago and has been traveling through space for the same amount of time.
Astronomer Alberto Conti and colleagues have developed a new technique to analyze massive galaxy data using computer analysis. By combining theoretical analysis with statistical techniques, they aim to uncover the most important attributes of galaxies that can be observed.
Despite intensive searches, only a few gamma ray burst counterparts have been found, leaving scientists with more questions than answers. The lack of consistent patterns hampers the search, but continued observations with powerful instruments may help clarify the issue.
