    Southern Utah Ring of Fire

    This is a mosaic of solar eclipse images secured on May 20, 2012 by Dr. Michael D. Joner. The individual observations were made between 6:59 and 8:06pm MDT a couple of miles northwest of Kanarraville, Utah on the center line of this annular solar eclipse. The entire solar photosphere was not blocked by the passage of the Moon for this eclipse. The result was an annular eclipse due to the fact that the Moon was close to apogee and thus not large enough in the sky to cover the entire Sun. Areas of southern Utah enjoyed perfect weather in addition to being ideally located to view the eclipse well before sunset.

    Slab-Stacking in Gd5(Si,Bi)4

    Structures based on stacking sequences of Gd5T4 slabs are determined by the directionality of interslab T-T dimers. These include giant-magnetocaloric compounds like Gd5Si2Ge2. In the T = (Si,Bi) system, substituting Si for Bi not only leads to the complete electronic/geometric cleavage of the interslab dimers, it removes the directionality of residual nearest-slab interactions, which facilitates novel stacking sequences and extensive stacking faults.

    Scattering Probes of Material Structure

    BYU physics researchers use some of the world's brightest x-ray and neutron sources to study the atomic structure and dynamics of advanced materials like superconductors and piezoelectrics. At the Spallation Neutron Source at Oak Ridge National Laboratory, accelerator-driven proton pulses bombard a liquid-mercury target, knocking high-energy neutrons from the target nuclei, which are then slowed in a moderator, collimated into beams, and scattered from material samples.

    Scattering Probes of Material Structure

    BYU physics researchers use some of the world's brightest x-ray and neutron sources to study the atomic structure and dynamics of advanced materials like superconductors and piezoelectrics. At the Advanced Photon Source at Argonne National Laboratory, electrons travel around a one-kilometer synchrotron ring at nearly the speed of light, emitting high-energy tangential Bremsstrahlung x-rays that are collimated into beams and scattered from material samples.

    Ready for Another Night

    University Photographer, Mark Philbrick, captured this sunset image of the BYU West Mountain Observatory in early June 2016. At the same time, Physics and Astronomy students were at work preparing the telescopes for yet another night of research observations. Data are secured on these nights for a wide variety of projects ranging from careful searches for exoplanets to monitoring active galaxies. The resulting data support research efforts of BYU students and faculty and in many cases contribute to larger international collaborations.
