EXPO: a quantum leap in fast, wide-band X-ray polarimetry for astrophysics
Paolo Soffitta, Sebastien Guillot, Ian Hutchinson +137
The Enhanced X-ray Polarimetry Observatory (EXPO) is a mission concept proposed to ESA as an M8 candidate, with a prospective launch in 2041. Building on the scientific success of…
Design of a mission to measure the shape and substructure of the 511 keV gamma-ray line from the center of the Milky Way
Kun Hu, Matthew Fritts, Daniel Becker +23
The 511 keV electron-positron annihilation feature near the galactic center has been detected for more than half a century, yet its origin remains a mystery. In this paper, we desc…
Systematic effects on a Compton polarimeter at the focus of an X-ray mirror
M. Aoyagi, R. G. Bose, S. Chun +23
XL-Calibur is a balloon-borne Compton polarimeter for X-rays in the 15-80 keV range. Using an X-ray mirror with a 12 m focal length for collecting photons onto a beryllium sc…
ASCENT - A balloon-borne hard X-ray imaging spectroscopy telescope using transition edge sensor microcalorimeter detectors
Fabian Kislat, Daniel Becker, Douglas Bennett +26
Core collapse supernovae are thought to be one of the main sources in the galaxy of elements heavier than iron. Understanding the origin of the elements is thus tightly linked to o…
The design and performance of the XL-Calibur anticoincidence shield
N. K. Iyer, M. Kiss, M. Pearce +31
The XL-Calibur balloon-borne hard X-ray polarimetry mission comprises a Compton-scattering polarimeter placed at the focal point of an X-ray mirror. The polarimeter is housed withi…
The 511-CAM Mission: A Pointed 511 keV Gamma-Ray Telescope with a Focal Plane Detector Made of Stacked Transition Edge Sensor Microcalorimeter Arrays
Farzane Shirazi, Md. Arman Hossen, Daniel Becker +18
The 511 keV gamma-ray emission from the galactic center region may fully or partially originate from the annihilation of positrons from dark matter particles with electrons from th…
