-
A.
IXPE X-ray Polarimetry Explorer
chosen
IXPE X-ray Polarimetry Explorer is a NASA space observatory designed to measure the polarization of cosmic X-rays to study extreme astrophysical environments such as black holes, neutron stars, and supernova remnants.
-
B.
X-ray polarimeter
An X-ray polarimeter is a scientific instrument designed to measure the polarization properties of X-ray radiation, providing insights into the physical conditions and geometries of high-energy astrophysical sources.
-
C.
X-ray Timing Instrument
The X-ray Timing Instrument is a high-precision detector system on NASA’s NICER mission designed to measure rapid X-ray brightness variations from neutron stars and other compact objects.
-
D.
Hitomi (ASTRO-H)
Hitomi (ASTRO-H) was a Japanese X-ray astronomy satellite designed to study high-energy phenomena in the universe, such as black holes, galaxy clusters, and supernova remnants.
-
E.
NuSTAR Nuclear Spectroscopic Telescope Array
NuSTAR (Nuclear Spectroscopic Telescope Array) is a space-based X-ray observatory that uses high-energy focusing optics to study black holes, neutron stars, supernova remnants, and other energetic cosmic phenomena.
