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. Continue reading
SMU’s experimental physics group played a pivotal role in discovering the Higgs boson — the particle that proves the theory for which two scientists have received the 2013 Nobel Prize in Physics.
The Royal Swedish Academy of Sciences awarded the Nobel Prize on Oct. 8 to theorists Peter W. Higgs and François Englert to recognize their work developing the theory of what is now known as the Higgs field, which gives elementary particles mass. Continue reading
The study found that among youth who have symptoms of depression, the risk is most severe for those who have one or more of three risk factors, said psychologist Chrystyna D. Kouros, Southern Methodist University, Dallas, who led the study. Continue reading
