Накратко на български

Галактическите ветрове, излизащи от галактики със свръхмасивни черни дупки, разкриват механизмите за тяхното създаване и разположение. Тези потоци от материя са масивни и могат да повлияят на еволюцията на цялата галактика.

Galactic Outflows and Feedback in the Astro-H eR

We have studied winds emanating from galaxies with supermassive black holes in their center. We advanced the understanding of the launch mechanism of these winds, where they are in their host galaxy, and what impact they may have on galactic evolution. The conclusions of our research is that these winds are relatively far away from the black hole, which also means they are massive and could impact the host galaxy. Astrophysical research is the most fundamental research that has no direct bearing on society. Indirectly, space research (our main tools are on board satellites) promotes space technology that in turn serves society. The overall objective of astrophysics is to understand of the universe, and in the context of GOFAR to understand the physics around black holes, and the mechanisms that drive galactic winds. We have contributed to this understanding. The hardware projects started with the NASA collaboration and continued at the Technion allowed us to build an instrument that would be launched to space soon and will provide further data on the energetic properties of X-ray and gamma-ray sources. This initiative and project is new to Israel and to Europe and is a direct result of the GOFAR project. This research will be exploited by the Israeli Space Agency who will fund our ongoing efforts to build detectors for space. GOFAR contributed to this effort both through its research results, but also via the connections and management training the PI obtained while working in the U.S. Further dissemination is our public outreach through the public talks, the international meetings, and the advanced graduate courses taught as a result of GOFAR.

Цел на проекта

Training: The GOFAR proposal is to train the Technion candidate to work on the Soft X-ray Spectrometer (SXS) built by NASA’s Goddard Space Flight Center (GSFC), for launch soon on the Japanese space observatory Astro-H that will be the working horse of X-Ray Astronomy in the next decade. The X-ray Astrophysics Laboratory at GSFC, the world centre for astrophysical X-ray spectroscopy and instrumentation will set up a data analysis facility at the adjacent University of Maryland (UMD), who will host GOFAR. Owing to its unprecedented combination of spectral resolution and sensitivity between 6 – 7 keV, the SXS will detect and measure, better than ever before, the hottest and most ionized X-ray astrophysical plasmas. GOFAR will thus position the candidate and his Technion group at the forefront of X-ray astrophysical research in the coming decade, but will also improve his project-management skills for the university hardware projects that he leads. Research: We propose to develop new spectroscopic diagnostics to match the spectral resolving power and sensitivity of the SXS for K- and L- shell ions in both photo- and collisionally- ionized plasmas, focusing on active galactic nuclei (AGN) outflows. We will measure the most ionized components of the winds, implied previously to dominate the outflow mass and energy. We propose to measure the location, mass outflow rate, and kinetic power of the wind, which govern its influence on the host galaxy. This will be the first opportunity to confirm and measure in detail the fastest components of AGN winds that were claimed to reach a fraction of the speed of light (~ 0.1c). Since the kinetic power in the wind scales as the outflow velocity cubed, these components are the most promising AGN energy feedback, and for enriching the intergalactic medium (IGM). We will attempt to identify absorption from filaments of the IGM, which represent the long sought-after missing atoms of the Universe.
