We have analyzed single pulses from PSR J0737-3039B, the 2.8 s pulsar in the recently discovered double pulsar system, using data taken with the Green Bank Telescope at 820 and 1400 MHz. We report the detection of features similar to drifting subpulses, detectable over only a fraction of the pulse window, with a fluctuation frequency of 0.196 cycles per period. This is exactly the beat frequency between the periods of the two pulsars. In addition, the drifting features have a separation within…

Radio Emission from the Double-Pulsar System J0737–3039 Revisited
The double pulsar J0737-3039 is the only known system in which the relativistic wind emitted by a radio pulsar demonstrably interacts with the magnetosphere of another one. We report radio
The Double Pulsar System J0737-3039: Modulation of A by B at Eclipse
We have investigated the eclipse of the 23 ms pulsar, PSR J0737-3039A, by its 2.8 s companion PSR J0737-3039B in the recently discovered double pulsar system using data taken with the Green Bank
The mean pulse profile of PSR J0737-3039A
General relativity predicts that the spin axes of the pulsars in the double-pulsar system PSR J0737-3039A/B will precess rapidly, in general leading to a change in the observed pulse profiles. We
The double pulsar system J0737 – 3039 – a 22.7 ms pulsar in a compact 2.4 hr orbit about a 2.7 s pulsar was one of the long-awaited "holy grails" of pulsar astronomy. After only two years of timing,
The double pulsar PSR J0737–3039A/B displays short, 30 s eclipses that arise around conjunction when the radio waves emitted by pulsar A are absorbed as they propagate through the magnetosphere of
We present the evolution of the radio emission from the 2.8 s pulsar of the double pulsar system PSR J0737- 3039A/B. We provide an update on the Burgay et al. analysis by describing the changes in
Long-term variations in the pulse emission from PSR J0737-3039B
Analysis of 20 months of observations at the Parkes radio telescope shows secular changes in the pulsed emission from J0737-3039B, the 2.77 s pulsar of the double-pulsar system. Pulse profiles are

The geometry of the double-pulsar system J0737–3039 from systematic intensity variations
A geometrical model of the PSR J0737–3039 system is reported that simultaneously explains the intensity variations of B and provides constraints on the spin axis orientation and emission geometry of A and predicts that A's pulse profile will evolve considerably over the next several years owing to geodetic precession.
Fluctuation and morphological properties of the pulsars in J0737--3039 system
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 the range of $\sim

The single-pulse characteristics of the millisecond pulsar PSR B1937+21 are studied using the recently installed Caltech baseband recorder at the Arecibo Radio Observatory in Puerto Rico. This is the
Pulse-to-pulse intensity modulation and drifting subpulses in recycled pulsars
We report the detection of pulse-to-pulse periodic intensity modulations, in observations of recycled pulsars. Even though the detection of individual pulses was generally not possible due to their
An increased estimate of the merger rate of double neutron stars from observations of a highly relativistic system
This work reports the discovery of a 22-ms pulsar, PSR J0737–3039, which is a member of a highly relativistic double-neutron-star binary with an orbital period of 2.4 hours, which implies an order-of-magnitude increase in the predicted merger rate for double- NEUTron- star systems in the authors' Galaxy (and in the rest of the Universe).
Theory of pulsar magnetospheres
There is a wide range of fundamental physical problems directly related to how pulsars function. Some of these are independent of the specific pulsar mechanism. Others relate directly to the physics
Second Periodic Pulsation in Pulsars
The pulses from pulsating radio sources seem to be made up of two subpulses, slow, class 1, and fast, class 2.
