Chandra Detection of Fe XVII in Absorption: Iron Abundance in the Hot Gaseous Interstellar Medium
Yangsen Yao, Norbert Schulz, Q. Daniel Wang +1
The iron depletion level and the gas-phase iron abundance in the hot ~10^6 K interstellar medium (ISM) is critical to the understanding of its energy balance as well as the thermal…
X-ray Flashes or soft Gamma-ray Bursts? The case of the likely distant XRF 040912
G. Stratta, S. Basa, N. Butler +49
In this work, we present a multi-wavelength study of XRF 040912, aimed at measuring its distance scale and the intrinsic burst properties. We performed a detailed spectral and temp…
Limits to Tertiary Astrometric Companions in Binary Systems
Matthew W. Muterspaugh, Benjamin F. Lane, S. R. Kulkarni +3
The Palomar High-precision Astrometric Search for Exoplanet Systems (PHASES) has monitored 37 sub-arcsecond binary systems to determine whether their Keplerian orbits are perturbed…
Extraordinarily Hot X-ray Emission from the 09 Emission Line Star HD 119682
C. E. Rakowski, N. S. Schulz, S. J. Wolk +1
We present new optical and X-ray observations to show that the X-ray source 1 WGA J1346.5--6255 previously associated with the SNR G309.2--0.6 can be unequivocally identified with…
The Onset of Quark-Hadron Duality in Pion Electroproduction
T. Navasardyan
A large data set of charged-pion electroproduction from both hydrogen and deuterium targets has been obtained spanning the low-energy residual-mass region. These data conclusively…
Rings and Bent Chain Galaxies in the GEMS and GOOD Fields
Debra Meloy Elmegreen, Bruce G. Elmegreen
Twenty-four galaxies with rings or partial rings were studied in the GEMS and GOODS fields out to z~1.4. Most resemble local collisional ring galaxies in morphology, size, and clum…
