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[edit | edit source]

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[edit | edit source]

Some of Caleb's major results include the first use of interferometry to detect fast radio bursts, in 2017,[1]Template:Ran confirmation of the extra-galactic origin of these bursts,[7]Template:Ran 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]Template:Ran and ASKAP J1935+2148 in 2024, with roughly 54 minutes per pulse.[4][5]Template:Ran
