Massive Black Holes Got Gas
In a paper submitted to the Monthly Notices of the Royal Astronomical Society, available online now here, astronomers from UC Berkeley discuss their computer simulations of the gas in the vicinity of massive black holes in the core of galaxies. Of note are the conclusions that black hole accretion rates and star formation rates are correlated, thus linking star formation rates to the active galactic nuclei (AGN) of galaxies. And if you are not impressed by those conclusions, perhaps you’ll be impressed by the movies developed by the computer simulations, which are available online here.
The Nature of X-ray Jets in Active Galactic Nuclei (AGN)
Most of the papers that I refer the reader to in this blog are very technical reports of the latest research. Often these are the most difficult for the general public to comprehend. Now you can find online at http://xxx.lanl.gov/PS_cache/arxiv/pdf/0812/0812.3401v1.pdf a precise, but approachable review of the nature of the X-ray jets emanating from active galaxies, or more precisely, active galactic nuclei (AGN) based upon the latest research results using the Chandra and XMM-Newton satellites. The author is Dr. Diana Worrall, who is an active researcher in AGNs at the University of Bristol (UK), and she presents an excellent summary of the latest understanding of AGNs, especially as seen through the best X-ray telescopes yet.
