The magnetar XTE J1810-197: variations in torque, radio flux density and pulse profile morphology
F. Camilo, I. Cognard, S. M. Ransom +8
We report on 9 months of observations of the radio-emitting anomalous X-ray pulsar XTE J1810-197 starting in 2006 May using the Nancay, Parkes, GBT, and VLA telescopes mainly at a…
{Interstellar Plasma Weather Effects in Long-term Multi-frequency Timing of Pulsar B1937+21
R. Ramachandran, P. Demorest, D. C. Backer +2
We report here on variable propagation effects in over twenty years of multi-frequency timing analysis of pulsar PSR B1937+21 that determine small-scale properties of the interveni…
Orbital Modulation of the Apparent Dispersion Measure Towards PSR J0737-3039A
Scott M. Ransom, Donald C. Backer, Paul Demorest +4
This paper has been withdrawn from astro-ph and from the submission process to ApJ Letters since the variations "observed" are not real. As pointed out to me first by Willem van St…
Fluctuation and morphological properties of the pulsars in J0737--3039 system
R. Ramachandran, D. C. Backer, P. Demorest +2
We describe the morphological and fluctuation properties of the pulsars in the double neutron star system, PSR J0737--3039. Pulsar B is seen in almost all orbital phases, except in…
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…
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…
