Solving the dark energy mystery: A new sky survey assignment for a 45-year-old telescope

SMU and other members of a scientific consortium prepare for installation of the Dark Energy Spectroscopic Instrument to survey the night sky from a mile-high mountain peak in Arizona As part of a large scientific consortium studying dark energy, SMU physicists are on course to help create the largest 3-D map of the universe ever [...]

Nearby massive star explosion 30 million years ago equaled brightness of 100 million suns

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.

Houston Chronicle: Texas scientists spot 12-billion-year old star explosion

Gamma ray burst, SMU, Kehoe, CBSThe Texas newspaper the Houston Chronicle covered the astronomy research of physicist Robert Kehoe, SMU professor, and two graduate students in the SMU Department of Physics, Farley Ferrante and Govinda Dhungana. The astronomy team in May reported observation of intense light from the enormous explosion of a star more than 12 billion years ago — shortly after the Big Bang — that recently reached Earth and was visible in the sky.

UPI: Cosmic explosions give dark energy clues

The Asian news wire service Asian News International has covered the SMU Physics Department's recent supernovae discoveries. The article, "Exploding stars offer clues to dark energy," was published Feb. 28. Light from two massive stars that exploded hundreds of millions of years ago recently reached Earth, and each event was identified as a supernova by SMU graduate students in the physics department.
