May 18, 2018 - Electromagnetic terahertz (THz) radiation is a versatile tool for a wide variety of sensing technologies ranging from security systems to medical applications. Commonly, THz radiation is created using photoconductive switches and nonlinear crystals. Recently, it was shown that optical excitation of fast spin current pulses in magnetic materials may generate strong THz radiation from transverse spin transport phenomena.
January 11, 2018- Dr. James MacDonald and Dr. Dermott Mullan recently derived the age of the quadruple star system KIC 7177553. The system appears to be younger than originally thought — it’s best modeled as being 32–36 million years old.
