Two new highly scattered fast radio bursts: evidence for scatter broadening by the circumsource medium
Joscha N. Jahns-Schindler, Keith W. Bannister, Adam T. Deller +17
We found two highly scattered Fast Radio Bursts (FRBs) during commissioning of the Commensal Realtime ASKAP Fast Transient COherent (CRACO) backend. FRB 240210D and FRB 240312D hav…

Imaging without visibilities: FAST-Effelsberg scintillometry of PSR B1508+55
Tim Sprenger, Xun Shi, Olaf Wucknitz +1
Context. The spatially coherent multipath propagation of pulsar radiation leads to a temporal and spectral interference patterns called scintillation. It is caused by density varia…

Scintillometry of Fast Radio Bursts: Resolution effects in two-screen models
Sachin Pradeep E. T, Tim Sprenger, Olaf Wucknitz +2
Fast Radio Bursts (FRBs) exhibit scintillation and scattering, often attributed to interactions with plasma screens in the Milky Way and the host galaxy. When these two screens app…
