The MeerKAT image of the intriguing 44-minute period object we recently discovered.
We recently made an intriguing discovery with the Australian Square Kilometre Array Pathfinder, located in Western Australia. We detected a mysterious, extremely bright source that has a long period. This source turns on every 44 minutes and exhibits unusual behavior for 3 minutes. To understand this phenomenon better, we conducted follow-up observations using state-of-the-art telescopes worldwide.
As part of this research, a student will work with data from the ASKAP radio telescope in Western Australia and the MeerKAT radio telescope in South Africa. They will learn how to create radio images using the data from radio interferometers. Additionally, the student will generate light curves and dynamic spectra of the source to investigate the evolution of its pulse properties, including millisecond sub-pulse structures.
