The Advanced X-ray Imaging Satellite (AXIS) Community Science Book
Michael Koss, Nafisa Aftab, Steven W. Allen +395
The AXIS Community Science Book represents the collective effort of 592 scientists worldwide to define the transformative science enabled by the Advanced X-ray Imaging Satellite (A…
AGN X-ray Reflection Spectroscopy with ML MYTORUS:Neural Posterior Estimation with Training on Observation-Driven Parameter Grids
Ingrid Vanessa Daza-Perilla, Panayiotis Tzanavaris, V. Madurga-Favieres +3
X-ray spectroscopy of active galactic nuclei (AGN) reveals key information about circumnuclear geometry. Many AGN show a narrow Fe K-alpha line at 6.4 keV and associated Compton-sc…
Extrapolation of Periodic Functions Using Binary Encoding of Continuous Numerical Values
Brian P. Powell, Jordan A. Caraballo-Vega, Mark L. Carroll +4
We report the discovery that binary encoding allows neural networks to extrapolate periodic functions beyond their training bounds. We introduce Normalized Base-2 Encoding (NB2E) a…
The high-speed X-ray camera on AXIS: design and performance updates
Eric D. Miller, Catherine E. Grant, Robert Goeke +25
AXIS, a Probe mission concept now in a Phase A study, will provide transformative studies of high-energy astrophysical phenomena thanks to its high-resolution X-ray spectral imagin…
