Measuring the Non-Axially-Symmetric Surface Temperature Distribution of the Central Compact Object in Puppis A
J. A. J. Alford, E. V. Gotthelf, R. Perna +1
The surface temperature distributions of central compact objects (CCOs) are powerful probes of their crustal magnetic field strengths and geometries. Here we model the surface temp…
Optical Studies of Ten Hard X-ray Selected Cataclysmic Binaries
J. P. Halpern, J. R. Thorstensen
We conducted time-resolved optical spectroscopy and/or photometry of ten cataclysmic binaries that were discovered in hard X-ray surveys, with the goal of measuring their orbital p…
Multi-Wavelength Observation Campaign of the TeV Gamma-Ray Binary HESS J0632+057 with NuSTAR, VERITAS, MDM, and Swift
Y. M. Tokayer, H. An, J. P. Halpern +53
HESS J0632+057 belongs to a rare subclass of binary systems which emits gamma-rays above 100 GeV. It stands out for its distinctive high-energy light curve, which features a sharp…
Radio Detection of PSR J1813-1749 in HESS J1813-178: The Most Scattered Pulsar Known
F. Camilo, S. M. Ransom, J. P. Halpern +1
The 44.7 ms X-ray pulsar in the supernova remnant G12.82-0.02/HESS J1813-178 has the second highest spin-down luminosity of known pulsars in the Galaxy, with E-dot=5.6e37 erg/s. Us…
Chandra, NuSTAR, and Optical Observations of the Cataclysmic Variables IGR J17528-2022 and IGR J20063+3641
Jeremy Hare, Jules P. Halpern, John A. Tomsick +5
We report on Chandra, NuSTAR, and MDM observations of two INTEGRAL sources, namely IGR J17528-2022 and IGR J20063+3641. IGR J17528-2022 is an unidentified INTEGRAL source, while IG…
