Single Pulse Dispersion Measure of the Crab Pulsar
N. Lewandowska, P. B. Demorest, M. A. McLaughlin +2
We investigate the use of bright single pulses from the Crab pulsar to determine separately the dispersion measure (DM) for the Main Pulse and Interpulse components. We develop two…
The NANOGrav 12.5-Year Data Set: Polarimetry and Faraday Rotation Measures from Observations of Millisecond Pulsars with the Green Bank Telescope
Haley M. Wahl, Maura McLaughlin, Peter A. Gentile +28
In this work, we present polarization profiles for 23 millisecond pulsars observed at 820 MHz and 1500 MHz with the Green Bank Telescope as part of the NANOGrav pulsar timing array…
The Pulsar in the Crab Nebula
Natalia Lewandowska
The Crab pulsar belongs to one of the most studied stellar objects in the sky. Since its accidental detection in 1968, its pulsed emission has been observed throughout most of the…
The absence of sub-minute periodicity in classical T Tauri stars
H. M. Günther, N. Lewandowska, M. P. G. Hundertmark +6
Classical T Tauri stars (CTTS) are young, late-type objects, that still accrete matter from a circumstellar disk. Analytical treatments and numerical simulations predict instabilit…
