Chasing a supernova

Argonne National Laboratory

Alec Lancaster, a theoretical physics and applied mathematics major at Loyola University in Chicago, is part of the Science Undergraduate Laboratory Internship (SULI) program, funded by DOE’s Office of Science. He spent the summer looking for a specific kind of supernova in the data from the Dark Energy Survey (DES), an intensive five-year probe of the southern sky. The ultimate goal of the research is to use known properties of those supernovae to determine the accelerated rate of expansion of the universe.

Detailed Early Observations of a Nearby Supernova and Associated Jet Cocoon Provide New Insights about Gamma-ray Bursts

George Washington University

An international team of researchers including Chryssa Kouveliotou, a professor of physics at the George Washington University, discovered the missing link connecting hypernovae to gamma-ray bursts in the form of a hot cocoon around the jets of matter expelled by the central engine as these spread through the outer layers of the progenitor star.

Citizen scientists help discover new exoplanet in ‘habitable zone’

University of Chicago

A new planet roughly twice the size of Earth has been discovered located within the “habitable zone”—the range of distances from a star where liquid water may exist on the planet’s surface. A research team that included a UChicago graduate student confirmed the finding after volunteer citizens flagged a crucial piece of evidence in data from NASA’s Kepler spacecraft.

Astronomers find signatures of a 'messy' star that made its companion go supernova

University of Washington

On Jan. 10 at the 233rd American Astronomical Society meeting in Seattle, an international team of astronomers announced that they have identified the type of companion star that made its partner in a binary system, a carbon-oxygen white dwarf star, explode.

NASA's Hubble Helps Astronomers Uncover Brightest Quasar in the Early Universe

Space Telescope Science Institute (STScI)

Astronomers using NASA's Hubble Space Telescope have discovered the brightest object ever seen at a time when the universe was less than one billion years old. The brilliant beacon is a quasar, the core of a galaxy with a black hole ravenously eating material surrounding it. The quasar would have gone undetected without its light being turbo-boosted by the gravitational field of a closer galaxy that is bending and amplifying the distant quasar’s light.

Professor’s work on detection of fast radio bursts detailed in Nature

West Virginia University

When researchers first began working on the Canadian Hydrogen Intensity Mapping Experiment, or CHIME, they envisioned a radio telescope that would make precise measurements of the acceleration of the Universe to improve the knowledge of why the expansion of the universe is accelerating. Instead, it has become ideal for detecting fast radio bursts—radio flashes happening from far outside the Milky Way galaxy.

Turn, turn, turn: New findings bring physicists closer to understanding the formation of planets and stars

Princeton Plasma Physics Laboratory

New findings further the understanding of a machine known as the magnetorotational instability experiment, which is named for and brings us closer to detecting the source of the instability that causes interstellar gas and dust to collapse into celestial bodies.
