Science journalist Alison Klesman with the online science news magazine Astronomy covered the discovery of a variable star by SMU professor Robert Kehoe and the astronomy team in the SMU Department of Physics.
New delta Scuti discovered at SMU is rare pulsating star 7,000 light years away and one of only seven in Milky Way galaxy.
SMU physicist Jodi Cooley, an associate professor in the Department of Physics, writes in the latest issue of Physical Review Letters about hunt by physicists worldwide for dark matter — the most elusive and abundant matter in our Universe.
Following its annual winter break, the most powerful collider in the world has been switched back on. Geneva-based CERN's Large Hadron Collider has been fine-tuned using low-intensity beams and pilot proton collisions. Now the LHC and its experiments are ready to take an abundance of data. The goal is to improve understanding of fundamental physics, driving future innovation and inventions.
A giant star that exploded 30 million years ago in a galaxy near Earth had a radius prior to going supernova that was 200 times larger than our sun, say astrophysicists at SMU. The massive explosion, Supernova 2013j, was one of the closest to Earth in recent years. Analysis of the exploding star's light curve and color spectrum found its sudden blast hurled material from it at 10,000 kilometers a second.
SMU scientists and their research have a global reach that is frequently noted, beyond peer publications and media mentions. It was a good year for SMU faculty and student research efforts. Here's a small sampling of public and published acknowledgements during 2015, ranging from research modeling that made the cover of a scientific journal to research findings presented as evidence at government hearings.
Physicists at Southern Methodist University, Dallas, have achieved a new precise measurement of a key subatomic particle, opening the door to better understanding some of the deepest mysteries of our universe.
Initial data from a new U.S.–based physics experiment indicates scientists are a step closer to understanding neutrinos, the second most abundant particle in the universe, says SMU physics professor Thomas Coan, a principal investigator on the project. Neutrinos are little understood, but indications are they hold clues to why matter overwhelmingly survived after the Big Bang instead of just energy in the form of light.
1st proton collisions at the world’s largest science experiment expected to start the first or second week of June
The schedule announcement came during an international physics conference on the SMU campus from senior research scientist Albert De Roeck, a staff member at CERN and a leading scientist on one of the Large Hadron Collider's key experiments in Geneva. “It will be about another six weeks to commission the machine, and many things can still happen on the way,” said De Roeck. The LHC in early April was restarted for its second three-year run after a two-year pause to upgrade the machine to operate at higher energies. At higher energy, physicists worldwide expect to see new discoveries about the laws that govern our natural universe.
