Professor Vik Dhillon is an Indian-origin astrophysicist at the University of Sheffield in the UK. He leads the ULTRACAM project. The ULTRACAM project uses a high-end camera to help scientists understand how the heaviest chemical elements are created in the universe. 

The camera was the first instrument to pinpoint the location of a gamma-ray burst that indicated the start of a kilonova explosion. Kilonovae are believed to be where most of the heaviest elements in the periodic table are produced, including gold, platinum, and uranium. 

Dhillon is part of a team of scientists that have made progress in understanding the creation of heavy chemical elements in the universe.

Professor Vik Dhillon, from the University of Sheffield’s Department of Physics and Astronomy who leads the ULTRACAM project, said the camera is the first instrument to pinpoint the location of the gamma-ray burst that indicated the start of the kilonova explosion

The discovery allows scientists to trigger other telescopes around the world for follow-up observations, including the James Webb Space Telescope (JWST). In the findings published in the ‘Nature’ journal this week, the scientists including those at the University of Sheffield observed the tell-tale red light from the kilonova, due to the absorption of blue light by the heavy elements produced in the explosion.

The presence of heavy elements was confirmed by observations with the JWST, which discovered tellurium in the infrared spectrum of the kilonova. Tellurium is next to iodine in the periodic table, implying significant quantities of iodine – essential for life on Earth – were also formed in the explosion

The UltraCam project created a large format digital aerial camera. The project was inspired by the 2000 ISPRS Congress in Amsterdam. The project’s goal was to increase flight efficiency to minimize flight costs, flying time, and project risk. 

The UltraCam is a portable, high-speed imaging photometer designed to study faint astronomical objects at high temporal resolutions. It uses updated hardware and a software design that aims to exploit the benefits of new software technologies. The project adopted the SDSU controller, which is in wide use at many of the world’s major ground-based telescopes. 

Vexcel Imaging introduced the UltraCam Merlin 4.1 Aerial Camera Systems, which is based on the 4th generation UltraCam architecture.
