Localization and Lensing of Fast Radio Bursts using CHIME/FRB and its VLBI Outriggers
… cosmological structure, and offer insights into magnetars: a rare class of neutron stars which produce the strongest magnetic fields in the Universe. However, because FRBs are so fleeting, the field is grappling with much simpler questions: How do magnetars emit FRBs? From what galaxies (and …

Simulations of Dynamic Relativistic Magnetospheres
… electromagnetic energy flows and is dissipated. Magnetars are believed to have twisted magnetospheres, due to internal magnetic evolution which deforms the crust, dragging the footpoints of external magnetic field lines. This twisting may be able to explain both magnetars' persistent hard X-ray …

Polarized Radiative Transfer in the Magnetospheres and Atmospheres of Neutron Stars
… of highly magnetized neutron stars like magnetars, calculating attenuation lengths and determining escape energies, which are the maximum photon energies for transparency out to infinity. These opacity calculations put constraints on the possible emission locales and the strengths of the …

Search and multi-frequency follow-up studies of radio transients: novel approaches and large campaigns
… towards highly magnetised neutron stars, such as magnetars, as the putative sources behind at least some of them. In particular, on April 2020 the Galactic magnetar SGR J1935+2154 emitted a radio flash closely resembling the ones produced by the FRBs, with simultaneous detections in the X-rays. …

Multiwavelength Studies of Rotating Radio Transients
… neutron star populations like the X-ray bright magnetars. However, some of the RRATs have spin-down properties very similar to those of normal pulsars, making it difficult to determine the cause of their unusual emission and possible evolutionary relationships between them and other classes of …

Nuclear and particle interactions to multi-messenger signals: Core-collapse supernovae
… driven by magnetorotational engines called protomagnetars. We find that outflows from these central engines can produce pions through inelastic np interactions, resulting in ~0.1 - 10 GeV neutrinos that are detectable for galactic supernovae. We also find that these outflows can synthesize …

Exotic Stars and Thorne-Żytkow Objects
… white dwarfs (B-WDs) and neutron stars (B-NS / magnetars) as well as the relevant microphysics that we must consider to study these objects. In particular I discuss the mechanisms by which thermal neutrinos can be produced in such objects. This is essential to understanding their cooling. In …
