Kavli Affiliate: Ralf K. Heilmann | First 5 Authors: Brandon D. Chalifoux, Ralf K. Heilmann, Herman L. Marshall, Mark L. Schattenburg, | Summary: Astronomical imaging with micro-arcsecond ($mu$as) angular resolution could enable breakthrough scientific discoveries. Previously-proposed $mu$as X-ray imager designs have been interferometers with limited effective collecting area. Here we describe X-ray telescopes achieving diffraction-limited […]

Requirements for future CMB satellite missions: photometric and band-pass response calibration

Posted by klaurent Tokyo

Kavli Affiliate: Tomotake Matsumura | First 5 Authors: Tommaso Ghigna, Tomotake Matsumura, Guillaume Patanchon, Hirokazu Ishino, Masashi Hazumi | Summary: Current and future Cosmic Microwave Background (CMB) Radiation experiments are targeting the polarized $B$-mode signal. The small amplitude of this signal makes a successful measurement challenging for current technologies. Therefore, very accurate studies to mitigate […]
