چکیده
Abstract The detection of quasi-periodic oscillations (QPOs) in magnetar giant flares (GFs) has brought a new perspective to studies the mechanism bursts. Due scarcity GFs, searching for QPOs short bursts is reasonable. Here we report narrow QPO at approximately 110 Hz and wide 60 burst SGR 150228213, with confidence level 3.35 σ . This was initially attributed 4U 0142+61 by Fermi/GBM on location, but have not detected such other from this magnetar. We also found that there repeating fast radio associated 150228213 location. Finally, discuss possible origins 150228213.

Forced Oscillations in Fluid Tori and Quasi–Periodic Oscillations
The kilo-Hertz Quasi–Periodic Oscillations in X–ray binaries could originate within the accretion flow, and be a signature of non–linear fluid oscillations and mode coupling in strong gravity. The possibility to decipher these systems will impact our knowledge of fundamental parameters such as the neutron star mass, radius, and spin. Thus they offer the possibility to constrain the nuclear equa...
متن کاملModels of Kilohertz Quasi-Periodic Brightness Oscillations
The remarkable discovery of kilohertz quasi-periodic brightness oscillations (QPOs) in the accretion-powered emission from some sixteen neutron-star low-mass Xray binary systems has led to much speculation about and theoretical modeling of the origin of these oscillations. It has also led to intense study of the implications that these QPOs have for the properties of neutron stars and of the ac...
متن کاملQuasi-periodic Oscillations from Magnetorotational Turbulence
Quasi-periodic oscillations (QPOs) in the X-ray lightcurves of accreting neutron star and black hole binaries have been widely interpreted as being due to standing wave modes in accretion disks. These disks are thought to be highly turbulent due to the magnetorotational instability (MRI). We study wave excitation by MRI turbulence in the shearing box geometry. We demonstrate that axisymmetric s...
متن کاملPeriodic Oscillations in the Analysis of Algorithms and Their Cancellations
A large number of results in analysis of algorithms contain fluctuations. A typical result might read “The expected number of . . . for large n behaves like log2 n + constant + delta(log2 n), where delta(x) is a periodic function of period one and mean zero.” Examples include various trie parameters, approximate counting, probabilistic counting, radix exchange sort, leader election, skip lists,...
متن کاملKeck II spectroscopy of mHz Quasi - Periodic Oscillations in
We present Keck II spectroscopy of an optical mHz quasi-periodic oscillations (QPOs) in the lightcurve of the X-ray pulsar binary Hercules X-1. In the power spectrum it appears as ‘peaked noise’, with a coherency ∼2, a central frequency of 35 mHz and a peak-to-peak amplitude of 5%. However, the dynamic power spectrum shows it to be an intermittent QPO, with a lifetime of ∼hundred seconds, as ex...
