Banner image: An artistic impression of a blue companion star stripping hydrogen from a yellow supergiant. Credit: Kavli IPMU/Aya Tsuboi A curiously yellow star has caused astrophysicists to reevaluate what’s possible within our universe. Led by Northwestern University, the international team used NASA’s Hubble Space Telescope to examine the massive star two-and-a-half years before it

Dr. Joe Bright worked with Prof. Margutti on radio observations and interpretation of astronomical transients. Dr. Bright was a CIERA Postdoc from 2020 – 2021. He is now a Postdoctoral Researcher at the University of Oxford.
Northwestern University expects to offer postdoctoral associate positions in observational astronomy and astrophysics starting in fall 2021. These positions will be part of the Center for Interdisciplinary Exploration and Research in Astrophysics (CIERA) at Northwestern. Successful applicants will benefit from interaction with a broad interdisciplinary group of researchers and will be immersed in a diverse and dynamic intellectual environment.
Unprecedented observations shine light on a compact star’s final moments Artist’s interpretation of the calcium-rich supernova 2019ehk. Shown in orange is the calcium-rich material created in the explosion. Purple coloring represents gas shedded by the star right before the explosion, which then produced bright X-ray emission when the material collided with the supernova shockwave. Image

Credit: Bill Saxton, NRAO/AUI/NSF ‘A new beast is out there,’ researcher says of object found in tiny galaxy Move aside, AT2018COW. There is a new astronomical transient in the universe, and it is faster, heavier and brighter at radio wavelengths than its mysterious predecessors. After
A supernova at least twice as bright and energetic, and likely much more massive than any yet recorded has been identified by an international team of astronomers, led by the University of Birmingham. The team, which included experts from Harvard, Northwestern University and Ohio University, believe the supernova, dubbed SN2016aps, could be an example of
Welcome New Postdoctoral Researchers! We are excited to introduce CIERA’s incoming Postdoctoral Research Fellows and Associates. They will bring a wide-range of expertise that promises to advance CIERA’s cutting-edge research programs. Evan Anders (U. Colorado) joins as a CIERA Fellow to study the effect of rotation on stellar convection using computational fluid dynamics.
The Northwestern-based YSE team is excited to announce the start of the Young Supernova Experiment, a new transient discovery survey using the Pan-STARRS1 and Pan-STARRS2 telescopes. This survey uses the large, 7-square degree field of view of the Pan-STARRS telescopes in Hawaii to identify new stellar explosions, stellar disruptions by supermassive black holes, and
