A Third Epoch Proper Motion Study of The Forward Shock in Kepler's Supernova Remnant
Sadie C. Coffin, Brian J. Williams, Satoru Katsuda
We present measurements of the expansion of Kepler's Supernova Remnant (SNR) over three epochs of Chandra X-ray observations from 2000, 2006, and 2014. As the remnant of a historic…
Charge-Injection Device Imaging of Sirius with Contrast Ratios Greater than 1:26 Million
Sailee M. Sawant, Daniel Batcheldor
The intrinsic nature of many astronomical objects, such as binary systems, exoplanets, circumstellar and debris disks, and quasar host galaxies, introduces challenging requirements…
Variability in Proto-Planetary Nebulae: VIII. A New Sample of Southern Hemisphere Objects
Bruce J. Hrivnak, Gary Henson, Todd C. Hillwig +5
As part of our continuing study of light variability in proto-planetary nebulae (PPNe), we present the results from a long-term study of nine southern hemisphere objects. We have m…
Fitting strategies of accretion column models and application to the broadband spectrum of Cen X-3
Philipp Thalhammer, Matthias Bissinger, Ralf Ballhausen +10
Due to the complexity of modeling the radiative transfer inside the accretion columns of neutron star binaries, their X-ray spectra are still commonly described with phenomenologic…
Simulating Reflected Light Exoplanet Spectra of the Promising Direct Imaging Target, Andromedae d, with a New, Fast Sampling Method Using the Planetary Spectrum Generator
Prabal Saxena, Geronimo L. Villanueva, Neil T. Zimmerman +2
Simulations of exoplanet albedo profiles are key to planning and interpreting future direct imaging observations. In this paper we demonstrate the use of the Planetary Spectrum Gen…
Computing Light-Front Wave Functions Without Light-Front Quantization: A Large-Momentum Effective Theory Approach
Xiangdong Ji, Yizhuang Liu
Light-front wave functions play a fundamental role in the light-front quantization approach to QCD and hadron structure. However, a naive implementation of the light-front quantiza…
