A study that sheds new light on how pulsar signals—the spinning remnants of massive stars—distort as they travel through space, published in The Astrophysical Journal, was led by Dr. Sofia Sheikh, SETI Institute researcher, and performed by a multi-year cohort of undergraduate researchers in the Penn State branch of the Pulsar Search Collaboratory student club.
