UA Professors Help in Discovery of Potential Cosmic Ray Source

In this artistic rendering, a powerful blazar is shown as the origin of a neutrino detected by IceCube. The Fermi observatory in space and MAGIC telescopes on Earth detected high-energy gamma rays from the same source.

From the September 2018 Desktop News | Three UA professors are part of an international team of scientists who found evidence of the source of tiny cosmic particles, known as neutrinos, a discovery that opens the door to using these particles to observe the universe. “We’re beginning to do astronomy using means other than light, combining electromagnetic (light) observations with other measurements in what we now call multimessenger astronomy,” said Dr. Marcos Santander, UA assistant professor of physics and astronomy. “This […]

With Project, Physics Professor ‘Pushing the Limit of Our Understanding’

Dr. Wang-Kong Tse was recently awarded a grant for his research examining van der Waals materials.

From the September 2018 Desktop News | Dr. Wang-Kong Tse, UA assistant professor of physics, was recently awarded a grant from the 2018 Early Career Research Program sponsored by the U.S. Department of Energy, one of 84 scientists from across the nation to receive funding. Tse will lead theoretical work in examining van der Waals materials, stacked, two-dimensional materials, when placed in what is called a non-equilibrium state, a condition where the material’s resting state is being perturbed by an external […]

UA Astronomer Helps Discover Elusive Black Hole

A NASA/ESA Hubble Space Telescope view of galaxy 6dFGS gJ215022.2-055059 – the large white-yellow blob at the center of the image – and neighboring galaxies, combined with X-ray observations of a black hole at the galaxy’s outskirts – the small white-purple dot to its lower left – obtained with NASA’s Chandra X-ray observatory.

From the August 2018 Desktop News | An astronomer at UA is part of an international team of researchers who found a mid-sized black hole, a cosmic oddity in observations of the universe. The finding, which demonstrates an effective method to detect this class of black holes, was announced recently in the journal Nature Astronomy. Two types of black holes are well-known. Massive stars create stellar-mass black holes when they die, while galaxies host supermassive black holes at their centers, with masses equivalent […]
