Understanding Massive Stars

Amit Kashi is a postdoc working on very massive stars with Kris Davidson and Roberta Humphreys. Kashi is working on stars that are typically a hundred times more massive than the Sun. Kashi says that these very massive stars are fundamentally different from others in that they are very unstable due to their size. The radiation from these objects, coming from the nuclear burning core, is so intense that it almost overcomes the gravity that is holding them together. More »

Paul Crowell

C-SPIN materials may comprise future computers

The end is near for CMOS technology, and Paul Crowell is trying to do something about that. “CMOS” stands for “complementary metal-oxide-semiconductor,” and CMOS technology is responsible for all the calculators, laptops, cell phones, tablets, and just about every non-abacus computing device in the world. Over the past 70 years or so, scientists and engineers have consistently made CMOS transistors smaller and more energy efficient, which is why your cell phone has more computing power than the most powerful mainframe in 1960.

Chaoyun Bao

Seeing through the Cosmic Fog

Chaoyun Bao is a graduate student in professor Shaul Hanany's Observational Cosmology lab. Hanany's group launched a microwave telescope called EBEX on a balloon at high altitude from Antarctica in 2012. During the balloon's 28-day trip around the Antarctic sky it gathered data on the Cosmic Microwave Background (CMB), which is a remnant signal from the Big Bang. Bao's job is to do data analysis and simulation for EBEX, including separating polarization anisotropies from foreground contamination signal from our own Milky Way galaxy. More »

Pamela Sooriyan

Physics Research Could Make Cancer Treatment More Effective

Pamela Sooriyan is a graduate student in biological Physics working with John Broadhurst. Her research involves bringing phenomenon in nuclear physics to cancer treatment. She is applying giant dipole resonance, a well-known nuclear phenomenon that occurs at energies that are typically at the higher end of the photon beam spectrum generated in clinical linear accelerators, to possibly increase the radiation dose given to tumors in bone.

Tambe Ebai Norbert

All in the Timing

Tambe Ebai Norbert is a graduate student working with Yuichi Kubota on physics beyond the standard model. He is part of the Compact Muon Solenoid (CMS) experiment located at the Large Hadron Collider (LHC) in Switzerland. Norbert’s expertise is in working with electronics of and analyzing data from the Electromagnetic Calorimeter (ECAL) portion of the experiment. The ECAL is made up of lead tungsten crystals which detect electromagnetic objects, i.e. photons and electrons. More »


Galaxy Zoo

Kyle Willett is a postdoctoral researcher working on the Galaxy Zoo experiment with Professor Lucy Fortson. Galaxy Zoo is a citizen science project in which hundreds of thousands of online volunteers help scientists sift through research data. The idea behind Galaxy Zoo and other citizen science initiatives is that there are certain types of identification tasks that it are very difficult to program a computer to do, but which people, even the general public with a small amount of introduction, can do readily.

Evan Frodermann

The Next Generation of Computer Coaches

Evan Frodermann is a post doc in the Physics Education Group, working with Ken Heller in a cross- discipline collaboration between the School and the College of Education and Human Development. Frodermann is helping to develop the second generation of computer coaches for use in physics classrooms. These computer coaches are designed to help teaching the skill of problem-solving in a physics context. More »

Vlad Pribiag

Towards Topological Quantum Computing

Vlad Pribiag is a condensed matter experimental physicist. His research focuses on novel low-dimensional semiconductors. He is particularly interested in materials with strong spin-orbit coupling, studying how the unique properties of certain materials can be used for information processing. Spin orbit coupling refers to the interaction between a particle’s spin and its motion. Physicists can control the spin by manipulating the motion of the particle. Physicists have found ways to encode either classical information or quantum information in the spin. More »

Eta Car

Eta Car: The Great Imposter

Two University astronomers, Kris Davidson and Roberta Humphreys have discovered that a massive binary star system, Eta Car is returning to its original state: that of a hot star easily visible in the sky of the Southern Hemisphere. Davidson and Humphreys have observed Eta Car since the Hubble Space Telescope first came online in 1990. This series of observations has given them solid evidence that Eta Car-- sometimes called the poster child for very massive stars, because it is the most massive star that is close enough to Earth to be easily observed—is experiencing dramatic changes.

Liliya Williams

Where is Dark Matter?

Liliya Williams is a Professor of Astrophysics working on the distribution of dark matter throughout the Universe. Using luminous matter such as stars and gas, Williams can trace dark matter and find patterns in the distribution. More »
