Stories of Hope: Hope Astrophysicists

Seeing Stars

Time travel, long imagined by writers and dreamers, is not as far-fetched as you might believe. Sure, it seems fantastical and improbable — the imaginings of which are only meant for postulations and movies — but astrophysicists do it all the time.

And so did Hope College freshman Jeff Engle in the summer of 2016 at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. All it took was expensive, highly powered, one-of-a-kind stellar equipment called the Fermi Gamma-Ray Space Telescope. That and funding and guidance from the Hope College physics department and Professor Dr. Peter Gonthier.

Probing High Temperature Superconductors with X-rays

Friday, April 7 at 3 pm in VW 104

Clement Burns Ph.D., Western Michigan University

Superconducting materials display a variety of unusual phenomenon, including the ability to carry electrical currents without resistance and the expulsion of magnetic fields from their volume.  Many of these systems are well understood, but over the last couple of decades several new classes of exotic superconductors have been discovered which cannot be explained with current theory.  In this talk I will discuss recent work using a free electron laser x-ray source at the SLAC accelerator laboratory to study the high temperature superconductor YBa2Cu4O7-x. Electrons in these systems show a new type of charge order which competes with the superconductivity, and this charge ordering may play an important role in the properties of these materials.
