معرفی
Rajan Chhetri is an Adjunct Research Associate at Curtin University, affiliated with the Curtin Research Institute and Curtin Institute of Radio Astronomy (CIRA), within the School of Electrical Engineering, Computing, and Mathematical Sciences. His research focuses on active galactic nuclei (AGNs), populations of radio sources, and multi-wavelength studies of extragalactic phenomena. He has conducted extensive work using radio interferometry and interplanetary scintillation techniques with instruments like the Murchison Widefield Array (MWA) and the Australia Telescope 20 GHz (AT20G) survey.
Chhetri’s investigations include studying compact AGNs at high radio frequencies, analyzing gravitational lensing in the Southern hemisphere, and exploring how AGNs interact with their galactic environments. His recent projects involve leveraging interplanetary scintillation to detect sub-arcsecond compact objects at low radio frequencies, enabling unprecedented resolution without upgrading telescope capabilities. This work contributes to understanding cosmic phenomena like supermassive black hole activity and the structure of the interplanetary medium.
His research outputs span over two decades, with notable contributions to surveys like GLEAM, AT20G, and MWA IPS, yielding insights into radio source populations, galaxy evolution, and space weather effects. Chhetri has also engaged in public outreach, bridging astronomy research with broader audiences.
