Dr. O'Meara was at the Magellan telescope at Las Campanas Observatory when he was contacted by collaborators Hsiao-Wen Chen of the University of Chicago and J. Xavier Prochaska of the University of California, San Diego and informed that NASA's SWIFT satellite had identified a candidate gamma ray burst.
“These are exciting events,” said Dr. O'Meara. “When a candidate burst is detected by satellites, telescopes all over the world race to see who can identify if it is indeed a gamma ray burst, and to obtain information like its brightness and distance—this time, our team came out on top." Dr. O’Meara said.
Dr. O'Meara used a spectrograph on the telescope shortly after the gamma ray burst to determine that it occurred nearly 9.5 billion years ago.
“These are some of the most distant objects we can see. And also some of the most poorly understood,” the astronomer said. “It's great to be one of the lucky ones who happens to be on the telescope at just the right time!” he added.Submitted findings to NASA’s Gamma Ray Burst Coordinates Network
According to the Las Campanas Observatory website, “The twin 6.5-meter Magellan telescopes are widely considered to be the best natural imaging telescopes in the world. They were built and continue to be operated by a consortium consisting of the Carnegie institution of Washington, Harvard, MIT, and the Universities of Michigan and Arizona. The telescopes are located at Carnegie's Las Campanas Observatory, high in the southern reaches of Chile's Atacama Desert. First light for the Walter Baade telescope occurred on September 15, 2000. The Landon Clay telescope started science operations on September 7, 2002.”
Dr. O'Meara is a resident of Essex Junction, Vt. His overall research interests include, among other areas, “Big Bang nucleosynthesis and light element abundances, Lyman limit and damped Lyman alpha systems, astrophysical properties of quasar absorption line systems, and galaxy-intergalactic medium interactions.”

Significantly more productivity in USP lasers

Shape matters when light meets atom

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
