We present the results of a systematic, unbiased search for subpulse modulation of 187 pulsars performed with the Westerbork Synthesis Radio Telescope (WSRT) in the Netherlands at an observing wavelength of 21 cm. Using new observations and archival WSRT data we have increased the list of pulsars that show the drifting subpulse phenomenon by 42, indicating that at least one in three pulsars exhibits this phenomenon. The real fraction of pulsars that show the drifting phenomenon is likely to be…

Statistics of the Drifting Subpulse Phenomenon
We present the statistical results of a systematic, unbiased search for subpulse modulation of 187 pulsars performed with the Westerbork Synthesis Radio Telescope (WSRT) in the Netherlands at an
The subpulse modulation properties of pulsars at 92 cm and the frequency dependence of subpulse modulation
Context: A large sample of pulsars has been observed to study their subpulse modulation at an observing wavelength (when achievable) of both 21 and 92 cm using the Westerbork Synthesis Radio
Characterizing the nature of subpulse drifting in pulsars
We report a detailed study of subpulse drifting in four long period pulsars. These pulsars were observed in the Meterwavelength Single-pulse Polarimetric Emission Survey and the presence of phase
Classification of subpulse drifting in pulsars
In this study we propose a classification scheme for the phenomenon of subpulse drifting in pulsars. We have assembled an exhaustive list of pulsars which exhibit subpulse drifting from previously
Exploring the remarkable subpulse drift and polarization properties of PSR B0818−41
PSR B0818 41 is one of the few pulsars which show multiple drift regions having well defined phase relationship. In this paper we report new resul ts from the multifrequency observations of this
S2DFS: analysis of temporal changes of drifting subpulses
Context. We introduce a new technique, called the sliding two-dimensional fluctuation spectrum, used for detecting and characterising the temporal changes of drifting subpulses from radio pulsars.
Subpulse modulation, moding and nulling of the five-component pulsar B1737+13
Recent Arecibo polarimetric observations of the bright five-component pulsar B1737+13 have facilitated a comprehensive analysis of its pulse-sequence modulation phenomena for the first time. The
Discovery of a remarkable subpulse drift pattern in PSR B0818–41
We report the discovery of a remarkable subpulse drift pattern in the relatively less-studied wide profile pulsar B0818−41 using high-sensitivity Giant Metrewave Radio Telescope (GMRT) observations.
Frequency dependence in the emission from subpulse drifting pulsars
We investigate relations in the emission properties as revealed by drifting subpulses detected at different observing frequencies based on the method that incorporates the rotating carousels in

Unraveling the drift behaviour of the remarkable pulsar PSR B0826–34
Pulsars with drifting subpulses are thought to be an important key to unlocking the mystery of how radio pulsars work. We present new results from high sensitivity GMRT observations of PSR B0826−34 -

S>The variation with longitude of the fluctuation spectrum of pulsar radio emission from a fired longitude is discussed for 13 pulsars. In particular, features in the fluctuation spectra are
The frequency-dependence of drifting subpulse patterns
Drifting subpulse patterns in pulsar signals are frequently interpreted in terms of a model in which a rotating ring of sparks on the polar cap gives rise to emission from regions of the
The polarization of drifting subpulses
Using new techniques based on the polarimetric fluctuation spectrum, the fluctuation behaviour of the polarization of individual pulses is examined in three pulsars that show drifting subpulses,

We introduce a model for pulsars in which nonradial oscillations of high spherical degree (l) aligned to the magnetic axis of a spinning neutron star reproduce the morphological features of pulsar
Mode switching and subpulse drifting in PSR B0826-34
We present high-quality observations of PSR B0826-34 at 1374 MHz. The emission from this pulsar exhibits strong bursts of pulses followed by long periods of 'null' pulses. When it is strong, the
Radio Emission of PSR J0437–4715 at 327 MHz
More than 412,000 single pulses from the brightest millisecond radio pulsar PSR J0437-4715 were obtained at 327 MHz using the Ooty Radio Telescope. This pulsar displays neither the nulling nor the
Long-term timing observations of 374 pulsars

A qualitative analysis is presented to account for the nulling phenomena observed pulsar radio emissions, which also feature an associated phase memory. The problem is that the radio signals are
