'''Manisha Pranati Caleb''' is an Indian and Australian astrophysicist whose research has used [[interferometry]] to detect [[fast radio burst]]s,{{r|sm}} studied the local context of fast radio bursts, used their signals as probes into the distribution of matter in the universe,{{r|sifa}} and discovered repeating signals from what may be very slowly-rotating [[neutron star]]s.{{r|graveyard|rules|telegraph}} She is a lecturer at the [[University of Sydney]], in the Sydney Institute for Astronomy.{{r|sifa}}<br />
<br />
==Education and career==<br />
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.{{r|sm|telegraph}} 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.{{r|ag}}<br />
<br />
She became a postdoctoral researcher at the [[University of Manchester]] in England{{r|sm}} before returning to Australia for her present position as a lecturer in the Sydney Institute for Astronomy of the University of Sydney.{{r|sifa}}<br />
<br />
==Research==<br />
Some of Caleb's major results include the first use of interferometry to detect fast radio bursts, in 2017,{{r|sm}}{{ran|B}} confirmation of the extra-galactic origin of these bursts,{{r|xt}}{{ran|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,{{r|graveyard}}{{ran|C}} and [[ASKAP J1935+2148]] in 2024, with roughly 54 minutes per pulse.{{r|rules|telegraph}}{{ran|D}}<br />
