The Phase II Murchison Widefield Array: Design Overview
Randall B. Wayth, Steven J. Tingay, Cathryn M. Trott +26
We describe the motivation and design details of the "Phase II" upgrade of the Murchison Widefield Array (MWA) radio telescope. The expansion doubles to 256 the number of antenna t…
Constraining the Spin-down of the Nearby Isolated Neutron Star RX J0806.4-4123, and Implications for the Population of Nearby Neutron Stars
D. L. Kaplan, M. H. van Kerkwijk
The nearby isolated neutron stars are a group of seven relatively slowly rotating neutron stars that show thermal X-ray spectra, most with broad absorption features. They are inter…
A Mid-Infrared Counterpart to the Magnetar 1E 2259+586
David L. Kaplan, Deepto Chakrabarty, Zhongxiang Wang +1
We report the discovery of a 4.5 um counterpart to the anomalous X-ray pulsar (magnetar) 1E 2259+586 with the Spitzer Space Telescope. The mid-infrared flux density is 6.3+/-1.0 uJ…
Constraining the Spin-down of the Nearby Isolated Neutron Star RX J2143.0+0654
D. L. Kaplan, M. H. van Kerkwijk
Magnetic field estimates for nearby isolated neutron stars (INS) help to constrain both the characteristics of the population and the nature of their peculiar X-ray spectra. From a…
Spectral and Rotational Changes in the Isolated Neutron Star RX J0720.4-3125
Marten H. van Kerkwijk, David L. Kaplan, George G. Pavlov +1
RX J0720.4-3125 is an isolated neutron star that, uniquely in its class, has shown changes in its thermal X-ray spectrum. We use new spectra taken with Chandra's Low Energy Transmi…
Lost and Found: A New Position and Infrared Counterpart for the X-ray Binary Scutum X-1
D. L. Kaplan, A. M. Levine, D. Chakrabarty +5
Using archival X-ray data, we find that the catalog location of the X-ray binary Scutum X-1 (Sct X-1) is incorrect, and that the correct location is that of the X-ray source AX J18…
