Variable Linear Polarization from Sagittarius A*: Evidence for a Hot Turbulent Accretion Flow
Geoffrey C. Bower, Heino Falcke, Melvyn C. H. Wright +1
We report the discovery of variability in the linear polarization from the Galactic Center black hole source, Sagittarius A*. New polarimetry obtained with the Berkeley-Illinois-Ma…
GBT Exploratory Time Observations of the Double-Pulsar System PSR J0737-3039
S. Ransom, P. Demorest, V. Kaspi +2
We report results from Exploratory Time observations of the double-pulsar system PSR J0737-3039 using the Green Bank Telescope (GBT). The large gain of the GBT, the diversity of th…
A 20-cm Survey for Pulsars in Globular Clusters using the GBT and Arecibo
Scott Ransom, Jason Hessels, Ingrid Stairs +3
We have been conducting deep searches at ~20 cm of >30 globular clusters (GCs) using the 305-m Arecibo telescope in Puerto Rico and the 100-m Green Bank telescope (GBT) in West Vir…
New Binary and Millisecond Pulsars from Arecibo Drift-Scan Searches
M. A. McLaughlin, D. R. Lorimer, D. J. Champion +6
We discuss four recycled pulsars found in Arecibo drift-scan searches. PSR J1944+0907 has a spin period of 5.2 ms and is isolated. The 5.8-ms pulsar J1453+19 may have a low-mass co…
Probing Relativistic Winds: The case of PSRJ07370-3039 A & B
Jonathan Arons, D. C. Backer, Anatoly Spitkovsky +1
We propose synchrotron absorption in a magnetosheath forming a cocoon around the magnetosphere of pulsar B to be the origin of the eclipse phenomena seen in the recently discovered…
Green Bank Telescope Measurement of the Systemic Velocity of the Double Pulsar Binary J0737-3039 and Implications for its Formation
S. M. Ransom, V. M. Kaspi, R. Ramachandran +5
We report on the measurement at 820- and 1400-MHz of orbital modulation of the diffractive scintillation timescale from pulsar A in the double-pulsar system J0737-3039 using the Gr…
