Detecting X-ray QPOs in Active Galaxies
نویسندگان
چکیده
Since EXOSAT produced the first good quality X-ray light curves of Seyfert galaxies there have been several claims of quasi-periodic oscillations (QPOs). None of these have withstood repeated analyses and observations. We review some problems concerning the detection of QPOs.

Where are the X - ray QPOs in active galaxies ?
In this paper we address the question of whether existing X-ray observations of Seyfert galaxies are sufficiently sensitive to detect quasi-periodic oscillations (QPOs) similar to those observed in the X-ray variations of Galactic Black Holes (GBHs). We use data from XMMNewton and simulated data based on the best RXTE long-term monitoring light curves, to show that if X-ray QPOs are present in ...
متن کاملWavelet analysis of MCG – 6 - 30 - 15 and NGC 4051 : a possible discovery of QPOs in 2 : 1 and 3 : 2 resonance
Following our previous work of Lachowicz & Czerny (2005), we explore further the application of the continuous wavelet transform to X-ray astronomical signals. Using the public archive of the XMM-Newton satellite, we analyze all available EPIC-pn observations for nearby Seyfert 1 galaxies MCG–6-30-15 and NGC 4051. We confine our analysis to 0.002–0.007 Hz frequency band in which, on the way of ...
متن کاملWide Area X-ray Surveys for AGN and Starburst Galaxies
While often the point sources in X-ray surveys are dominated by AGN, with the high sensitivity of modern X-ray telescopes such as Chandra and XMM-Newton normal/starburst galaxies are also being detected in large numbers. We have made use of Bayesian statistics for both the selection of galaxies from deep X-ray surveys and in the analysis of the luminosity functions for galaxies. These technique...
متن کاملUsing SKA to observe relativistic jets from X-ray binary systems
I briefly outline our current observational understanding of the relativistic jets observed from X-ray binary systems, and how their study may shed light on analogous phenomena in Active Galactic Nuclei and Gamma Ray Bursts. How SKA may impact on this field is sketched, including the routine tracking of relativistic ejections to large distances from the binaries, detecting and monitoring the ra...
متن کاملThe Weak Outnumbering the Mighty: Normal Galaxies in Deep Chandra Surveys
Chandra is detecting a significant population of normal and starburst galaxies in extremely deep X-ray exposures. For example, approximately 15% of the sources arising in the 2 Ms Chandra Deep Field-North survey are fairly normal galaxies, where “normal” means “Milky Way-type” X-ray emission rather than simply exhibiting an “optically normal” spectrum. Many of these galaxies are being detected ...
