Dielectronic recombination of Fe 3pq ions : a key ingredient for describing X-ray absorption in active galactic nuclei [PDF]

, 2006
We have carried out multiconfiguration Breit-Pauli AUTOSTRUCTURE calculations for the dielectronic recombination (DR) of Fe8+-Fe12+ ions. We obtain total DR rate coefficients for the initial ground level that are an order of magnitude larger than those ...

The clustering of galaxies in the SDSS-III Baryon Oscillation Spectroscopic Survey: measurements of the growth of structure and expansion rate at z=0.57 from anisotropic clustering [PDF]

, 2012
We analyse the anisotropic clustering of massive galaxies from the Sloan Digital Sky Survey III Baryon Oscillation Spectroscopic Survey (BOSS) Data Release 9 (DR9) sample, which consists of 264 283 galaxies in the redshift range 0.43 0.57, and when ...

Black Hole Mergers and Their Electromagnetic Counterparts [PDF]

, 2011
Over the past ten years it has become increasingly clear that most, if not all, galaxies have super-massive black holes lurking in their cores. The implications for this are large as they not only have significant effects on the host galaxies, far beyond

Kirkpatrick‐Baez (KB) and Lobster Eye (LE) Optics for Astronomical and Laboratory Applications

X-Ray Optics and Instrumentation, Volume 2010, Issue 1, 2010., 2010
Most of grazing incidence (reflective) X‐ray imaging systems used in astronomy and in other (laboratory) applications are based on the Wolter 1 (or modified) arrangement. But there were proposed also other designs and configurations, which are considered for future applications for both in laboratory and (finitely) in space.

In Situ Detection of Opal‐A in Jezero Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract We report the in situ detection of amorphous hydrated silica in the Bills Bay abrasion patch, located in the eastern portion of the Margin Unit between the rim of Jezero crater and the western delta. Here, hydrated silica co‐occurs with olivine, Fe‐Mg carbonates, secondary Fe‐Mg silicates, and hydrated Mg‐sulfate as determined by UV Raman ...

X-ray emission from accreting black holes [PDF]

, 2003
In this thesis I use state of the art models of x-ray emission from accreting black holes in order to observationally constrain the accretion geometry.
