Manisha Caleb

Dr. Manisha Caleb is a Research Fellow at the University of Sydney's School of Physics, specializing in astrophysics with a focus on neutron stars, fast radio bursts (FRBs), and radio transients. Her research leverages cutting-edge facilities like MeerKAT and ASKAP to explore extreme astrophysical phenomena.

Her work includes groundbreaking discoveries such as the 76-second pulsar PSR J0901-4046 and the characterization of magnetar XTE J1810-197. She leads the MeerTRAP survey, which has localized over a dozen FRBs and Galactic radio transients in real-time. Dr. Caleb's DECRA grant (2022) supports her exploration of localized FRBs as cosmological probes.

Research interests span pulsar emission mechanisms, FRB polarization properties, magnetar outburst dynamics, and multi-messenger astrophysics. Key collaborations involve the CSIRO, MeerKAT telescope, and international teams analyzing transient data from optical/X-ray/TeV instruments.

Awards include the ARC Discovery Early Career Researcher Award (DECRA). Her findings challenge theoretical models of neutron star evolution and contribute to understanding the origins of transient radio signals.

Dr. Caleb's lab works closely with the Sydney Institute for Astronomy and the Australian Research Council Centre of Excellence for Gravitational Wave Discovery (OzGrav). Ongoing projects include analyzing FRB host galaxies and developing real-time transient detection algorithms.
