Newly detected short radio pulse appears to come from far beyond our galaxy（图）
Radio telescopes Pulse A quick radio burst Signal Radio The pulsar. The observatory The Milky Way
2014/7/18
The discovery of a split-second burst of radio waves using the Arecibo radio telescope in Puerto Rico provides important new evidence of mysterious pulses that appear to come from deep in outer space.
Pulse-amplitude-resolved spectroscopy of bright accreting pulsars: indication of two accretion regimes
X-ray binaries – neutron stars – accretion
2011/10/8
Context: In addition to coherent pulsation, many accreting neutron stars exhibit flaring activity and strong aperiodic variability on time scales comparable to or shorter than their pulsation period. ...
On the pulse-width statistics in radio pulsars. II. Importance of the core profile components
stars:pulsars:general – stars:neutron – stars:rotation
2011/9/27
We performed a statistical analysis of half-power pulse-widths of the core components in average pulsar profiles. We confirmed an existence of the lower bound of the distribution of half-power pulse-w...
Radio Properties of Rotating Radio Transients I: searches for periodicities and randomness in pulse arrival times
stars:neutron – pulsars: general – Galaxy: stellar content
2011/9/28
We have analysed the long- and short-term time dependence of the pulse arrival times and the pulse detection rates for eight Rotating Radio Transient (RRAT) sources from the Parkes Multi-beam Pulsar S...
Varying disc-magnetosphere coupling as the origin of pulse profile variability in SAX J1808.4-3658
accretion accretion discs – pulsars:individual:SAX J1808.4–3658 – stars:neu-tron – X-rays:binaries
2011/9/26
Accreting millisecond pulsars show significant variability of their pulse profiles, especially at low accretion rates. On the other hand, their X-ray spectra are remarkably similar with not much varia...

Pulse Phase Dependence of the Magnetar Bursts
Gamma rays bursts—neutron stars magnetars individual (SGR 1806–20, SGR 1900+14 and AXP 1E 2259+586)—X-rays bursts
2009/5/12
We report here results from a study of X-ray bursts from 3 magnetar
candidates (SGR 1806–20, SGR 1900+14 and AXP 1E 2259+586).
We have searched for a pulse phase dependence of the X-ray burst rate
