Using the XMM-Newton small window mode to investigate systematic uncertainties in the particle background of X-ray charge-coupled device detectors

Posted by dbos MIT

Kavli Affiliate: Eric D. Miller | First 5 Authors: Gerrit Schellenberger, Ralph Kraft, Paul Nulsen, Eric D. Miller, Marshall W. Bautz | Summary: The level and uncertainty of the particle induced background in CCD detectors plays a crucial role for future X-ray instruments, such as the Wide Field Imager (WFI) onboard Athena. To mitigate the […]

Measurement of the Branching Fraction of $Λ_c^+ to p K_S^0 π^0$ at Belle

Posted by dbos Tokyo

Kavli Affiliate: T. Higuchi | First 5 Authors: The Belle, Belle II Collaborations, :, I. Adachi, L. Aggarwal | Summary: We report a precise measurement of the ratio of branching fractions $mathcal{B}(Lambda_c^+to p K_S^0 pi^0)/mathcal{B}(Lambda_c^+to p K^- pi^+)$ using 980 fb$^{-1}$ of $e^+e^-$ data from the Belle experiment. We obtain a value of $mathcal{B}(Lambda_c^+to p […]

Quasi-periodic oscillations of GHz-band polarization in a black hole

Posted by dbos Peking

Kavli Affiliate: Luis C. Ho | First 5 Authors: Wei Wang, Jiashi Chen, Pengfu Tian, Luis C. Ho, Xiaohui Sun | Summary: Relativistic jets from accreting black holes (BHs) radiate non-thermal emission which is highly variable in different time scales. Magnetic fields anchored to a rotating BH or accretion disc accelerate and collimate jets of […]
