Physics Colloquium April 7, 2016

The Department of Physics & Astrophysics is pleased to present a colloquium by Deniz Cakir, Department of Physics at the University Antwerp, Belgium. “Electronic and optical properties of monolayer and few-layer black phosphorus: a DFT perspective” will be held April 7, 2016 at 4:00 p.m. in Witmer Hall, Room 211.

Phosphorene, or monolayer black phosphorus, is a new 2D layered material with high carrier mobility and direct semiconducting band gap. One of the most interesting characters of phosphorene is highly anisotropic electronic and optical properties due to its anisotropic puckered atomic structure, making it a very promising material for electronics and optoelectronics applications.

Reaching for the Stars: UND Student Team Searches for Distant Dwarf Galaxies

Working at a cosmological scale, “huge” doesn’t begin to cover it when physics major Haylee Archer peers deep into the universe.

Madina Sultanova, St. Cloud, Minn.; Sandanuwan Kalawila, from Sri Lanka; Gregory Foote, Los Angeles; and Haylee Archer, Finley, N.D.; members of a University of North Dakota team of physics and astrophysics student team, recently went to Arizona to study distant dwarf galaxies using the Kitt Peak National Observatory.

Archer, from Finley N.D., is part of a UND team that recently searched for distant dwarf galaxies using the Kitt Peak National Observatory in Arizona. Booking time on that scientific instrument and any other big telescope is seriously competitive.

The four-student team–Archer; Gregory Foote, Los Angeles; Madina Sultanova, St. Cloud, Minn.; and Sandanuwan Kalawila, from Sri Lanka–is working with UND’s Wayne Barkhouse, associate professor in the Department of Physics & Astrophysics, part of the UND College of Arts & Sciences.

Barkhouse, originally from one of Canada’s Maritime provinces, studies galaxy clusters, extragalactic globular clusters and is an associate member of the international Dark Energy Survey. He’s also a member of the Large Scale Structure LSST Science Collaboration. Read more

UND Astrophysicist Helps Confirm that Einstein Got it Right

Albert Einstein got it right 100 years ago when he predicted gravitational waves, the space equivalent of ripples in a pond.wayne-barkhouse

“Yes, researchers have just proved the reality of gravitational waves, and that’s a huge development,” said Wayne Barkhouse, a University of North Dakota astrophysicist and associate member of a group that helped to confirm Einstein’s prediction. “This discovery is going to affect space science and how we think about the universe in a major way.” Read more

Astronomy Talk September 21, 2015

The Department of Physics & Astrophysics public talk and telescope observing session will take place Monday September 21, 2015 at 8:00 p.m. in Witmer Hall, room 116. The talk “Event Horizons” will be presented by Dr. William Schwalm, Department of Physics and Astrophysics, University of North Dakota. Following the talk, attendees will be given the opportunity to observe the night sky through a telescope (weather permitting).
