On September 14, 2015, at 4:51 a.m. Central Time, scientists witnessed something no human had ever seen before: two black holes colliding. These black holes, which were 29 and 36 times the mass of the sun, respectively, had been circling each other for millions of years. Their rotations became increasingly faster until they eventually collided and became a single black hole. Since then, scientists have had numerous breakthroughs that deepen our understanding of the universe, and researchers in the College of Arts and Science have been at the forefront, shaping the scientific field of black holes and gravitational waves.

Over the next four years, Assistant Professor of Physics and Astronomy Alex Lupsasca will lead a Vanderbilt team in a multidisciplinary, multi-institutional collaboration funded by an $8 million grant from the Simons Foundation with a focus on black holes and strong gravity. Read More

Ultra-thin layers of gold and copper sulfide developed by Vanderbilt doctoral student Yueming Yan with Associate Professor of Chemistry Janet Macdonald and Stevenson Professor of Physics Richard Haglund could revolutionize medical imaging and environmental sensing. The energy exchange between the metal and semiconductor particles—resonant energy transfer—can convert infrared light into visible and ultraviolet colors. The nanoscale films "could replace bulky optical sensors with flexible, wearable or even implantable devices, thus transforming health and safety technologies." Read More

While we know that intermediate-mass black holes should exist, little is known about their origins or characteristics—they are considered the rare “missing links” in black hole evolution. However, four new studies have shed new light on the mystery. The research was led by a team in the lab of Assistant Professor of Physics and Astronomy Karan Jani, who also serves as the founding director of the Vanderbilt Lunar Labs Initiative. Read More

Undergraduate research is a defining experience at Vanderbilt, providing students the opportunity to think critically, apply their knowledge, and engage in the scientific process. However, students also grow in unexpected ways beyond just technical skills they learn in the lab. Read More

The third annual Honors Banquet commemorated excellence in academics, leadership and innovation among Graduate School students and faculty. On March 20, the banquet was held to honor and reflect on remarkable achievements in research and creative expression from the more than 50 graduate programs and departments represented in the Graduate School.

Hunting for black holes sounds like the premise of a new Hollywood blockbuster, but at Vanderbilt University, Assistant Professor of Physics and Astronomy Karan Jani works with students in a lab to do exactly that. Last year, Jani’s group at the Department of Physics and Astronomy, along with the university’s Data Science Institute, jointly launched the AI for New Messengers postdoctoral fellowship. The fellowship, one of the first of its kind in the U.S., seeks to apply AI techniques to analyze data from cosmic events (such as black hole collisions) using information from the Nobel Prize–winning Laser Interferometer Gravitational-Wave Observatory (LIGO) experiment.
