Breaking the AMSP mould: the increasingly strange case of HETE J1900.1-2455
Duncan K. Galloway, Edward H. Morgan, Deepto Chakrabarty
We present ongoing Rossi X-ray Timing Explorer (RXTE) monitoring observations of the 377.3 Hz accretion-powered pulsar, HETE J1900.1-2455 Activity continues in this system more tha…
The Burst Spectra of EXO 0748-676 during a Long 2003 XMM-Newton Observation
J. Cottam, F. Paerels, M. Méndez +4
Gravitationally redshifted absorption lines from highly ionized iron have been previously identified in the burst spectra of the neutron star in EXO 0748-676. To repeat this detect…
Probing Unification With Chandra HETGS and XMM-Newton EPIC And RGS Spectroscopy of the Narrow Emission Line Galaxy NGC 2110
Daniel A. Evans, Julia C. Lee, T. Jane Turner +2
We present results from Chandra HETGS (250 ks over two epochs) and XMM-Newton EPIC and RGS (60 ks) observations of NGC 2110, which has been historically classified as a Narrow Emis…
Constraints on the Self-Gravity of Radiation Pressure via Big Bang Nucleosynthesis
Saul Rappaport, Josiah Schwab, Scott Burles
Using standard big-bang nucleosynthesis and present, high-precision measurements of light element abundances, we place constraints on the self-gravity of radiation pressure in the…
Outer jet X-ray and radio emission in R Aquarii: 1999.8 to 2004.0
E. Kellogg, C. Anderson, K. Korreck +5
Chandra and VLA observations of the symbiotic star R Aqr in 2004 reveal significant changes over the three to four year interval between these observations and previous observation…
Discovery of an X-ray Jet and Extended Jet Structure in the Quasar PKS 1055+201
D. A. Schwartz, H. L. Marshall, J. E. J. Lovell +10
This letter reports rich X-ray jet structures found in the Chandra observation of PKS 1055+201. In addition to an X-ray jet coincident with the radio jet we detect a region of exte…
