Recent Publication(s)

  • "The complete spectrum of the neutron star x-ray binary 4U 0614+091"

Migliari S, Tomsick JA, Miller-Jones JCA, Heinz S, et al., Astrophysical Journal 710(1): 117-124 Feb 2010.  The authors conclude that for realistic jet size, boosting, viewing angle, and energy partition, the SSC emission alone, from the post-shock, accelerated, non-thermal population in the jet, is not a viable mechanism to explain the observed hard X-ray tail of the NS 4U0614+091. 

  • "Prospects of high-resolution x-ray spectoscopy for active galactic nucleus feedback in galaxy clusters"

Heinz S, Bruggen M, Morsony B, Astrophysical Journal 708(1): 462-468 Jan 2010.  Using numerical simulations of jet-driven cavities in fully dynamically evolved clusters and a new virtual X-ray observatory tool, we demonstrate that high-resolution, high-throughput X-ray spectroscopy will be able to determine the expansion velocity of these cavities and that the International X-ray Observatory will have the necessary capabilities to deliver the necessary measurements.

  • "Discovery of a large and bright bow shock nebula associated with low-mass X-ray binary SAX J1712.6-3739"

Wiersema K, Russell DM, Degenaar N, et al., Monthly Notices of the Royal Atronomical Society 397 (1): L6-L10 Jul 2009. In a multiwavelength programme dedicated to identifying optical counterparts of faint persistent X-ray sources in the Galactic bulge, the authors find an accurate X-ray position of SAX J1712.6-3739 through Chandra observations, and discover its faint optical counterpart using our data from EFOSC2 on the ESO 3.6-m telescope. the authors find this source to be a highly extincted neutron star low-mass X-ray binary (LMXB) with blue optical colours 

  • "A parsec scale X-ray extended structure from the X-ray binary Circinus X-1"

Soleri P, Heinz S, Fender R, et al., Monthly Notices of the Royal Astronomical Society 397 (1): L1-L5 Jul 2009. The authors present the results of the analysis of two Chandra observations of Circinus X-1 performed in 2007, for a total exposure time of similar to 50 ks. The source was observed with the High Resolution Camera during a long X-ray low-flux state of the source. 

  • "A Deep Chandra Observation of Abell 4059: A New Face to “Radio-Mode” AGN Feedback?"

Reynolds CS, Casper EA, Heinz S. ASTROPHYSICAL JOURNAL 679 (2): 1181-1191 JUN 1 2008. A deep Chandra observation of the cooling core cluster Abell 4059 (A4059) is presented. The data strengthens previous suggestions that the southwestern ridge is colder and denser than, but in approximate pressure equilibrium with, the surrounding ICM atmosphere. In addition, the authors find evidence for a weak shock that wraps around the north and east sides of the cavity structure.

  • "Evolution of X-ray cavities"

Brueggen M, Scannapieco E, Heinz S, Monthly Notices of the Royal Astronomical Society 395 (4): 2210-2220 Jun 2009. Here, the authors combine numerical simulations that include subgrid turbulence and software that produces synthetic Xray observations to examine the evolution of X-ray cavities in the absence of magnetic fields. Keywords: Hydrodynamics; Active Galactic Nuclei; Perseus Cluster; Galaxy Clusters; Chandra Observation; Intracluster Medium; Radio Bubbles; Elliptic Galaxy.
