Simultaneous single-pulse observations of radio pulsars
In this paper we demonstrate that a large, unexplored reservoir of information about pulsar emission exists, that is directly linked to the radiating particles and their radiation process: We present a study of flux density measurements of individual pulses simultaneously observed at four different frequencies. Correcting for effects caused by the interstellar medium, we derive intrinsic flux d...
متن کاملSimultaneous Single-Pulse Observations of Radio Pulsars: V. On the Broadband Nature of The Pulse Nulling Phenomenon in PSR
Aims. In this paper we revisit the well-known phenomenon of pulse nulling using high-quality single-pulse data of PSR B1133+16 from simultaneous multifrequency observations. Methods. Observations were made at 325, 610, 1400 and 4850 MHz as part of a joint program between the European Pulsar Network (EPN) and the Giant Metrewave Radio Telescope (GMRT). The pulse energy time series are analysed t...
متن کاملASTRONOMY AND ASTROPHYSICS Simultaneous single-pulse observations of radio pulsars II. Orthogonal polarization modes in PSR B1133+16
In this paper, we present a study of orthogonal polarization modes in the radio emission of PSR B1133+16, conducted within the frame of simultaneous, multi-frequency, single-pulse observations. Simultaneously observing at two frequencies (1.41 GHz and 4.85 GHz) provides the means to study the bandwidth of polarization features such as the polarization position angle. We find two main results. F...
متن کاملSimultaneous multi - frequency single - pulse properties of AXP XTE J 1810 – 197
We have used the 76-m Lovell, 94-m equivalent WSRT and 100-m Effelsberg radio telescopes to investigate the simultaneous single-pulse properties of the radio emitting magnetar AXP XTE J1810–197 at frequencies of 1.4, 4.8 and 8.35 GHz during May and July 2006. We study the magnetar’s pulse-energy distributions which are found to be very peculiar as they are changing on time-scales of days and ca...
متن کاملSimultaneous multi - frequency observations of PG 1553 + 113
We report simultaneous multi-frequency observations of the blazar PG 1553+113, that were carried out in March-April 2008. Optical, X-ray, high-energy (HE: ≥ 100 MeV) γ-ray, and very-highenergy (VHE: ≥ 100 GeV) γ-ray data were obtained with the KVA, REM, RossiXTE/ASM, AGILE and MAGIC telescopes. This is the first simultaneous broad-band (i.e., HE+VHE) γ-ray observation of a blazar. The source sp...
