Kavli Affiliate: Sven Herrmann | First 5 Authors: Artem Poliszczuk, Dan Wilkins, Steven W. Allen, Eric D. Miller, Tanmoy Chattopadhyay | Summary: Traditional cosmic ray filtering algorithms used in X-ray imaging detectors aboard space telescopes perform event reconstruction based on the properties of activated pixels above a certain energy threshold, within 3×3 or 5×5 pixel […]

Kavli Affiliate: Sven Herrmann | First 5 Authors: Peter Orel, Abigail Y. Pan, Sven Herrmann, Tanmoy Chattopadhyay, Glenn Morris | Summary: The Advanced X-ray Imaging Satellite (AXIS) is a NASA probe class mission concept designed to deliver arcsecond resolution with an effective area ten times that of Chandra (at launch). The AXIS focal plane features […]

Kavli Affiliate: Sven C. Herrmann | First 5 Authors: Haley R. Stueber, Tanmoy Chattopadhyay, Sven C. Herrmann, Peter Orel, Tsion Gebre | Summary: Future strategic X-ray satellite telescopes, such as the probe-class Advanced X-ray Imaging Satellite (AXIS), will require excellent soft energy response in their imaging detectors to enable maximum discovery potential. In order to […]

Kavli Affiliate: Daniel R. Wilkins | First 5 Authors: Tanmoy Chattopadhyay, Sven Herrmann, Peter Orel, Kevan Donlon, Steven W. Allen | Summary: Single electron Sensitive Read Out (SiSeRO) is a novel on-chip charge detection technology that can, in principle, provide significantly greater responsivity and improved noise performance than traditional charge coupled device (CCD) readout circuitry. […]

Kavli Affiliate: Bruce Macintosh | First 5 Authors: Briley L. Lewis, Michael P. Fitzgerald, Thomas M. Esposito, Pauline Arriaga, Ronald Lopez | Summary: The 16 Myr-old A0V star HD 156623 in the Scorpius–Centaurus association hosts a high-fractional-luminosity debris disk, recently resolved in scattered light for the first time by the Gemini Planet Imager (GPI) in […]

Kavli Affiliate: Nicola Omodei | First 5 Authors: Josephine Wong, Tsunefumi Mizuno, Niccoló Bucciantini, Roger W. Romani, Yi-Jung Yang | Summary: We present Crab X-ray polarization measurements using IXPE data with a total exposure of 300ks, three times more than the initial 2022 discovery paper. Polarization is detected in three times more pulsar phase bins, […]

Kavli Affiliate: Roger W. Romani | First 5 Authors: Chien-Ting J. Chen, Ioannis Liodakis, Riccardo Middei, Dawoon E. Kim, Laura Di Gesu | Summary: We present multiwavelength polarization measurements of the luminous blazar Mrk~501 over a 14-month period. The 2–8 keV X-ray polarization was measured with the Imaging X-ray Polarimetry Explorer (IXPE) with six 100-ks […]
