Scattering variability detected from the circumsource medium of FRB 20190520B
S. K. Ocker, J. M. Cordes, S. Chatterjee +5
Fast radio bursts (FRBs) are millisecond-timescale radio transients, the origins of which are predominantly extragalactic and likely involve highly magnetized compact objects. FRBs…
Heliosphere Meets Interstellar Medium, in a Galactic Context
Stella Koch Ocker, James Cordes, Shami Chatterjee +8
The physical conditions within our heliosphere are driven by the Sun's motion through an evolving interstellar environment that remains largely unexplored. The next generation of o…
A Scintillation Arc Survey of 22 Pulsars with Low to Moderate Dispersion Measures
Dan R. Stinebring, Barney J. Rickett, Anthony H. Minter +6
Context: By providing information about the location of scattering material along the line of sight (LoS) to pulsars, scintillation arcs are a powerful tool for exploring the distr…
Radio Scattering Horizons for Galactic and Extragalactic Transients
S. K. Ocker, J. M. Cordes, S. Chatterjee +1
Radio wave scattering can cause severe reductions in detection sensitivity for surveys of Galactic and extragalactic fast (ms duration) transients. While Galactic sources lik…
Magnetic field reversal in the turbulent environment around a repeating fast radio burst
Reshma Anna-Thomas, Liam Connor, Shi Dai +27
Fast radio bursts (FRBs) are brief, intense flashes of radio waves from unidentified extragalactic sources. Polarized FRBs originate in highly magnetized environments. We report ob…
