The associated fireball was observed evening New Year’s Day by eight all-sky cameras PRISMA network, a partner FRIPON. computed trajectory had an inclination angle approximately 68° and velocity at infinity 12.8 km s−1. Together with relatively low terminal height, estimated as 21.5 km, those values were indicating significant possibility dropping event, additionally confirmed...
X-rays are particularly suited to probe the physics of extreme objects. However, despite enormous improvements X-ray Astronomy in imaging, spectroscopy and timing, polarimetry remains largely unexplored. We propose photoelectric polarimeter Gas Pixel Detector (GPD) as an instrument candidate fill gap more than thirty years lack measurements. The GPD, focus a telescope, will increase sensitivity orders magnitude. Moreover, since it can measure energy, position, arrival time polarization angle...

Future lightweight and long-focal-length x-ray telescopes must guarantee a good angular resolution (e.g., 5 arc sec HEW) reach an unprecedented large effective area. This goal can be reached with the slumping of borosilicate glass sheets that allow fabrication low-cost optical units (XOU). These XOUs, based on mirror segments, have to assembled together form complete multishell Wolter-I optics. The technology for integration these XOUs is under development in Europe, funded by European Space...
