Manisha Caleb

Last updated

Manisha Pranati Caleb is an Indian and Australian astrophysicist whose research has used interferometry to detect fast radio bursts, [1] studied the local context of fast radio bursts, used their signals as probes into the distribution of matter in the universe, [2] and discovered repeating signals from what may be very slowly-rotating neutron stars. [3] [4] [5] She is a lecturer at the University of Sydney, in the Sydney Institute for Astronomy. [2]

Education and career

Caleb was a student at Stella Maris College, Chennai in India from 2007 to 2010. She went to University College London in England for a master's degree involving spacecraft and satellite communications. Next, she became a doctoral student at the Australian National University, where she began her work on fast radio bursts. [1] [5] Her 2017 doctoral dissertation, A pursuit of fast radio transients with the UTMOST and Parkes radio telescopes, was jointly supervised by Frank Briggs, Brian Schmidt, Matthew Bailes, and Chris Flynn. [6]

She became a postdoctoral researcher at the University of Manchester in England [1] before returning to Australia for her present position as a lecturer in the Sydney Institute for Astronomy of the University of Sydney. [2]

Research

Some of Caleb's major results include the first use of interferometry to detect fast radio bursts, in 2017, [1] [B] confirmation of the extra-galactic origin of these bursts, [7] [A] and the discoveries of ultra-long-period pulsars PSR J0901–4046 in 2020, the former slowest known pulsar at roughly 76 seconds per pulse, [3] [C] and ASKAP J1935+2148 in 2024, with roughly 54 minutes per pulse.
