A Hotspot for Powerful Cosmic Rays

Physicists a Step Closer to Finding Mysterious Sources

July 8, 2014 – An observatory run by the University of Utah found a “hotspot” beneath the Big Dipper emitting a disproportionate number of the highest-energy cosmic rays. The discovery moves physics another step toward identifying the mysterious sources of the most energetic particles in the universe.

“This puts us closer to finding out the sources – but no cigar yet,” says University of Utah physicist Gordon Thomson, spokesman and co-principal investigator for the $25 million Telescope Array cosmic ray observatory west of Delta, Utah. It is the Northern Hemisphere’s largest cosmic ray detector.

“All we see is a blob in the sky, and inside this blob there is all sorts of stuff – various types of objects – that could be the source” of the powerful cosmic rays, he adds. “Now we know where to look.”

A new study identifying a hotspot in the northern sky for ultrahigh-energy cosmic rays has been accepted for publication by Astrophysical Journal Letters.

Thomson says many astrophysicists suspect ultrahigh-energy cosmic rays are generated by active galactic nuclei, or AGNs, in which material is sucked into a supermassive black hole at the center of galaxy, while other material is spewed away in a beam-like jet known as a blazar. Another popular possibility is that the highest-energy cosmic rays come from some supernovas (exploding stars) that emit gamma rays bursts.

Lower-energy cosmic rays come from the sun, other stars and exploding stars, but the source or sources of the most energetic cosmic rays has been a decades-long mystery.

The study was conducted by 125 researchers in the Telescope Array project, including Thomson and 31 other University of Utah physicists, plus 94 other scientists from the University of Tokyo and 28 other research institutions in Japan, the United States, South Korea, Russia and Belgium.

Bryce Canyon Astronomy Festival

From the Bryce Canyon National Park Website

2014 Bryce Canyon Astronomy Festival: Star Stories from Down Under

Join us for our 14th Annual Astronomy Festival (June 25 - 28, 2014) where Bryce Canyon's Dark Rangers and the Salt Lake Astronomical Society welcome Australia's award-winning photographer and amateur astronomer Alex Cherney. Don't miss this keynote presentation on Friday, June 27 at 9:15 pm -- Alex's debut appearance in the United States. See his stunning photography from the wilds of Australia and New Zealand -- two of the few places on Earth with even darker night skies than Bryce Canyon. In the Australian Outback the Milky Way is so bright that many of the native people's constellations were not made in connect-the-dots fashion from star-patterns, but from the 3-dimensional dark clouds (stellar cocoons) within the Milky Way.

If you've ever dreamed of going on an Australian night-sky "walk-about," here's your chance to follow in the footsteps of an expert. Listen to Alex tell of these 20,000-year-old sky stories, and his own adventures in the wilds of Australia, beneath the backdrop of his stunning night sky videography set to moving music. In the meantime, enjoy some samples of his talent here.

Helping the Public Reach for the Stars

U Opens Astronomy Center June 11 for Star Parties & More

June 5, 2014 – The University of Utah has a new location for people who enjoy outer space. The Astronomy Outreach Center will begin operating at 7 p.m. Wednesday, June 11 with an open house, a brief lecture and a party to observe the sun and stars.

The university’s Department of Physics and Astronomy has held star parties for years on the roof of the South Physics Building. The new space— located in room 408 below the rooftop observatory— finally provides a permanent, roughly 30-seat gathering place for astronomy presentations and demonstrations for the public, K-12 students, scouting and community groups and private and public star parties.

“In the past, when a school group would want to come to us and have a presentation or activity, we would have to search around for a classroom not in use at a given time. This often wouldn’t work,” says astronomer Tabitha Buehler, coordinator of the new center and head of a university astronomy outreach group known as the AstronomUrs.

“Now we have a space that is dedicated to public outreach, so we can accommodate more groups,” says Buehler, who is also an assistant professor-lecturer in physics and astronomy. “One responsibility of the university is to reach out to people and educate them about the different exciting things up here.”

The idea for the Astronomy Outreach Center began when former physics and astronomy chair Dave Kieda, now dean of the U’s Graduate School, and Harold Simpson, the department’s facilities director, were devising new ways to improve the department and get it more involved with the community, Buehler says.

The center also will be the base for remote-controlled operations of the university’s Willard L. Eccles Observatory at the 9,600-foot level on Frisco Peak in southern Utah.

The June 11 opening will feature public use of solar telescopes at 7 p.m., a brief presentation about the sun at 8:40 p.m. followed by a public star party.

Free parking will be available after 6 p.m. in the two parking lots east of the South Physics Building. More details and a map are located here.

To request and schedule a public astronomy event – either at the Astronomy Outreach Center or off-campus – schools, community organizations and other groups should email the center at:
