Discovery of PSR J1227-4853: A transition from a low-mass X-ray binary to a redback millisecond pulsar
Jayanta Roy, Paul S. Ray, Bhaswati Bhattacharyya +12
XSS J12270-4859 is an X-ray binary associated with the Fermi LAT gamma-ray source 1FGL J1227.9-4852. In 2012 December, this source underwent a transition where the X-ray and optica…

We present the results of 71.6 hours of observations of the Geminga pulsar (PSR J0633+1746) with the VERITAS very-high-energy gamma-ray telescope array. Data taken with VERITAS bet…
The hard X-ray spectrum of NGC 5506 as seen by NuSTAR
G. Matt, M. Balokovic, A. Marinucci +12
NuSTAR observed the bright Compton-thin, narrow line Seyfert 1 galaxy, NGC 5506, for about 56 ks. In agreement with past observations, the spectrum is well fit by a power law with…
A NuSTAR observation of the fast symbiotic nova V745 Sco in outburst
M. Orio, V. Rana, K. L. Page +2
The fast recurrent nova V745 Sco was observed in the 3-79 keV X-rays band with NuSTAR 10 days after the optical discovery. The measured X-ray emission is consistent with a collisio…
ASTRO-H White Paper - Chemical Evolution in High-z Universe
M. S. Tashiro, D. Yonetoku, M. Ohno +7
In this paper, we demonstrate ASTRO-H's capability to measure the chemical evolution in the high-z (z <~ 3) universe by observing X-ray afterglows of gamma-ray bursts (GRBs) and di…
ASTRO-H White Paper - High Resolution Spectroscopy of Interstellar and Circumgalactic Gas in the Milky Way and Other Galaxies

We describe the potential of high resolution imaging spectroscopy with the SXS on ASTRO-H to advance our understanding of the interstellar- and circumgalactic media of our own Gala…
ASTRO-H White Paper - New Spectral Features
R. K. Smith, H. Odaka, M. Audard +27
This white paper addresses selected new (to X-ray astronomy) physics and data analysis issues that will impact ASTRO-H SWG observations as a result of its high-spectral-resolution…
ASTRO-H White Paper - Low-mass X-ray Binaries
C. Done, M. Tsujimoto, E. Cackett +20
There is still 10-20% uncertainty on the neutron star (NS) mass-radius relation. These uncertainties could be reduced by an order of magnitude through an unambiguous measure of M/R…
Investigating Broadband Variability of the TeV Blazar 1ES 1959+650
E. Aliu, S. Archambault, T. Arlen +92
We summarize broadband observations of the TeV-emitting blazar 1ES 1959+650, including optical R-band observations by the robotic telescopes Super-LOTIS and iTelescope, UV observat…
Searches for continuous gravitational waves from nine young supernova remnants
J. Aasi, B. P. Abbott, R. Abbott +887
We describe directed searches for continuous gravitational waves in data from the sixth LIGO science data run. The targets were nine young supernova remnants not associated with pu…
Coordinated X-ray, Ultraviolet, Optical, and Radio Observations of the PSR J1023+0038 System in a Low-mass X-ray Binary State
Slavko Bogdanov, Anne M. Archibald, Cees Bassa +14
The PSR J1023+0038 binary system hosts a neutron star and a low-mass, main-sequence-like star. It switches on year timescales between states as an eclipsing radio millisecond pulsa…
Accretion-powered pulsations in an apparently quiescent neutron star binary
Anne M. Archibald, Slavko Bogdanov, Alessandro Patruno +10
Accreting millisecond X-ray pulsars are an important subset of low-mass X-ray binaries in which coherent X-ray pulsations can be observed during occasional, bright outbursts (X-ray…
The Hard X-Ray View of the Young Supernova Remnant G1.9+0.3
Andreas Zoglauer, Stephen P. Reynolds, Hongjun An +12
NuSTAR observed G1.9+0.3, the youngest known supernova remnant in the Milky Way, for 350 ks and detected emission up to 30 keV. The remnant's X-ray morphology does not change…
