A Melody in the Noise: Modeling Echoes of the Crab Nebula
Thierry Serafin Nadeau, Marten H. van Kerkwijk
Pulses from the Crab pulsar are often followed by "echoes", produced by radiation that was deflected by structures in the Crab nebula and thus traveled via longer paths. We describ…
Echoes in Different Tempo: Long-Term Monitoring of Crab Echoes with CHIME
Thierry Serafin Nadeau, Marten H. van Kerkwijk, Jing Luo +4
The Crab Pulsar is known to feature plasma lensing events known as echoes. These events are characterized by additional components in the pulse profile which are produced by additi…
Scintillation Properties of PSR B1133+16 Measured with Very Long Baseline Interferometry
Ashley M. Stock, Fardin Syed, Marten H. van Kerkwijk +3
The scintillation of pulsars reveals small-scale structure of the interstellar medium. A powerful technique for characterizing the scintillating structures (screens) combines analy…
Associations Between Scattering Screens and Interstellar Medium Filaments
Ashley M. Stock, Marten H. van Kerkwijk
Pulsar scintillation can be used to measure small scale structure in the Galaxy, but little is known about the specific interstellar medium features that cause scintillation. We se…
