Quantum resources in resource management systems

Utz Bacher, Mark Birmingham, Christopher D. Carothers +14

Quantum computing resources are increasingly being incorporated into high-performance computing (HPC) environments as co-processors for hybrid workloads. To support this paradigm,…

The nature of the 4th track in GX 5-1: discovery of Fe XXVI RRC in massive flares

M. J. Church, O. Dimbylow, C. Peach +1

We present an explanation of the 4th branch of the Z-track based on analysis of high-quality RXTE data on the source GX 5-1. Spectral analysis shows that the physical evolution on…

The periodic bursters XB1323-619 and GS1826-24: longterm evolution of the nuclear burning regime and comparison with theory

M. Balucinska-Church, D. Reed, M. J. Church

The majority of X-ray burst sources do not display a burst rate that increases with luminosity as expected, but this is seen in the two clocked bursters XB1323-619 and GS1826-24. W…

An explanation of the Z-track sources

M. J. Church, G. S. Halai, M. Balucinska-Church

We present an explanation of the Z-track phenomenon based on spectral fitting of RXTE observations of GX340+0 using the emission model previously shown to describe the dipping LMXB…

Discovery of hard X-ray features around hotspots of Cygnus A

M. Balucinska-Church, M. Ostrowski, L. Stawarz +1

We present results of analysis of a Chandra observation of Cygnus A in which the X-ray hotspots at the ends of the jets are mapped in detail. A hardness map reveals previously unkn…

Ultra-Luminous X-ray Source Populations in Normal Galaxies: a Preliminary Survey with Chandra

P. J. Humphrey, G. Fabbiano, M. Elvis +2

We present results of a Chandra survey of the ultra-luminous X-ray sources (ULX) in 13 normal galaxies, in which we combine source detection with X-ray flux measurement. 22 ULX wer…
