Associate Professor Esteban D. Araya, of Western Illinois University's Department of Physics, received a $148,000 grant from the National Science Foundation (NSF) to support a three-year project researching the earliest phases of star formation. "Collaborative Research: A Multiscale Approach to Understand Outflows During High-Mass Star Formation" is a combined effort between WIU and the New Mexico Institute of Mining and Technology (which also received an NSF grant) to study the role of outflows during the formation of the most massive stars in our Galaxy.
Scientists, including researchers from the Department of Energy's SLAC National Accelerator Laboratory, have compiled the most detailed catalog of such blobs using eight years of data collected with the Large Area Telescope (LAT) on NASA's Fermi Gamma-Ray Space Telescope. The blobs, including 19 gamma-ray sources that weren't known to be extended before, provide crucial information on how stars are born, how they die, and how galaxies spew out matter trillions of miles into space.
To forge nanodiamonds, which have potential applications in medicine, optoelectronics and quantum computing, researchers expose organic explosive molecules to powerful detonations in a controlled environment. These explosive forces, however, make it difficult to study the nanodiamond formation process. To overcome this hurdle, researchers recently developed a procedure and a computer model that can simulate the highly variable conditions of explosions on phenomenally short time scales. They report their work in The Journal of Chemical Physics.
Eddie Lee, doctoral student in physics at Cornell University, applied a statistical physics model to a "Super Court" of 36 Supreme Court justices and 24 nine-member courts from 1946 to 2016 and found was that consensus dominates the court, and strong correlations in voting far outlast any one justice or court
The Science of Consciousness (TSC) 2019 is the 26th annual international interdisciplinary conference on fundamental questions and cutting-edge issues connected with conscious experience.
LIVERMORE, Calif. -- Sandia National Laboratories researcher Jacqueline Chen has been elected as a fellow of the American Physical Society.This honor is afforded each year to no more than 0.5 percent of the members of the society.Chen was honored "for fundamental insights into turbulence-chemistry interactions revealed through massively parallel direct numerical simulations.
Next-Gen Ultrafast Optical Fiber-Based Electron Gun to Reveal Atomic Motions During Transition State
A new method enables researchers to directly observe and capture atomic motions at surfaces and interfaces in real time.
Researchers experimentally observed the ionization-induced channeling of an intense microwave beam propagating through a neutral gas (>103 Pa).
Leon Lederman, a co-winner of the 1988 Nobel Prize in physics for the discovery of the muon neutrino, spent his life as a leader in a range of roles promoting science. He died on October 3, 2018, at the age of 96. Lederman conducted his Nobel Prize-winning research at the U.S. Department of Energy's Brookhaven National Laboratory in the early 1960s.
TRIUMF, Canada's particle accelerator centre, is pleased to launch its new Five-Year Plan 2020-2025, developed with extensive internal and external community consultation. It leverages past investments by government and builds on the laboratory's strong brand and global network to deliver a new level of top-tier science, training, and innovation to Canada for decades to come.
The American Physical Society (APS), the world's largest physics organization, has elected three scientists from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory as 2018 APS fellows.
New observations of a stellar phenomenon by a team of researchers, including University of Minnesota astrophysicists, has solved a 348-year-old mystery.
A West Virginia University professor joins the ranks of luminaries Carl Sagan, Richard Feynman and Nobel laureates as the recipient of the prestigious Hans Christian Oersted Medal from the American Association of Physics Teachers.
Optical frequency combs can enable ultrafast processes in physics, biology, and chemistry, as well as improve communication and navigation, medical testing, and security. Columbia Engineers have built a Kerr frequency comb generator that, for the first time, integrates the laser with the microresonator, significantly shrinking the system's size and power requirements. They no longer need to connect separate devices using fiber--they can now integrate it all on compact and energy efficient photonic chips.
Using ALMA, an international team of astronomers found evidence that a white dwarf and a brown dwarf collided in a short-lived blaze of glory that was witnessed on Earth in 1670 as Nova sub Capite Cygni (a New Star below the Head of the Swan), which is now known as CK Vulpeculae.
The astrophysicists Mattia Galiazzo and Rudolf Dvorak from the University of Vienna, in collaboration with Elizabeth A. Silber (Brown University, USA) investigated the long-term path development of Centaurs (solar system minor bodies which originally have orbits between Jupiter and Neptune). These researchers have estimated the number of close encounters and impacts with the terrestrial planets after the so-called Late Heavy Bombardment (about 3.8 billion years ago) as well as the possible sizes of craters that can occur after a collision with the Earth (and the other terrestrial planets). The publication was recently published in Monthly Notices of the Royal Astronomical Society.
American Society of Mechanical Engineers names PPPL an historic landmark site.
In the world of catalytic reactions, polymers created through electropolymerization are attracting renewed attention. A group of Chinese researchers recently provided the first detailed characterization of the electrochemical properties of polyaniline and polyaspartic acid (PASP) thin films. In AIP Advances, the team used a wide range of tests to characterize the polymers, especially their capacity for catalyzing the oxidation of popularly used materials, hydroquinone and catechol.
A team of physicists has devised a novel strategy that uses naturally occurring motions inside the human cell nucleus to measure the physical properties of the nucleus and its components. The method offers a potential new means for illuminating the physical properties of unhealthy cells, such as those linked to Alzheimer's and Parkinson's disease.
Magnetic reconnection causes space storms that can damage satellites and disrupt the grid. While it's a common process in the universe, plasma physics researchers don't fully understand why it occurs so abruptly and quickly. New research is supporting a theory that may hold the key.
Physicist Kawtar Hafidi has been appointed Associate Laboratory Director, Physical Sciences and Engineering at the U.S. Department of Energy's (DOE) Argonne National Laboratory.
Capturing ultrafast atomic-scale motion could help scientists optimize the performance of materials with strong electronic correlations.
The first-ever detection of highly energetic radiation from a microquasar has astrophysicists scrambling for new theories to explain the extreme particle acceleration. A microquasar is a black hole that gobbles up debris from a nearby companion star and blasts out powerful jets of material.
