Kavli Affiliate: Roger W. Romani | First 5 Authors: Martijn de Vries, Roger W. Romani, Oleg Kargaltsev, George Pavlov, Bettina Posselt | Summary: We have obtained a deep 670 ks CXO ACIS image of the remarkable pulsar wind nebula (PWN) of PSR J1709-4429, in 4 epochs during 2018-2019. Comparison with an archival 2004 data set […]
Kavli Affiliate: Philip J. Marshall | First 5 Authors: Ji Won Park, Sebastian Wagner-Carena, Simon Birrer, Philip J. Marshall, Joshua Yao-Yu Lin | Summary: We investigate the use of approximate Bayesian neural networks (BNNs) in modeling hundreds of time-delay gravitational lenses for Hubble constant ($H_0$) determination. Our BNN was trained on synthetic HST-quality images of […]
Kavli Affiliate: Rainer Spurzem | First 5 Authors: Qi Shu, Xiaoying Pang, Francesco Flammini Dotti, M. B. N. Kouwenhoven, Manuel Arca Sedda | Summary: We present a comprehensive investigation of main-sequence (MS) binaries in the DRAGON simulations, which are the first one-million particles direct $N$-body simulations of globular clusters. We analyse the orbital parameters of […]
Kavli Affiliate: Ralf K. Heilmann | First 5 Authors: Hans Moritz Günther, Ralf K. Heilmann, , , | Summary: Lynx is one of four large-mission concept studies for NASA’s 2020 Decadal survey. The design reference mission includes an X-ray grating spectrometer (XGS) based on critical-angle transmission (CAT) gratings. In the past we studied different grating […]
Kavli Affiliate: Herman L. Marshall | First 5 Authors: Hans Moritz Günther, Herman L. Marshall, Alan Garner, , | Summary: X-ray polarimetry is still largely uncharted territory. With the upcoming launch of IXPE, we will learn a lot more about X-ray polarization at energies above 2 keV, but so far no current or accepted mission […]
Kavli Affiliate: Satoshi Shirai | First 5 Authors: Taisuke Katayose, Shigeki Matsumoto, Satoshi Shirai, , | Summary: Electroweakly Interacting Massive Particles (EWIMPs), in other words, new massive particles that are charged under the electroweak interaction of the Standard Model (SM), are often predicted in various new physics models. EWIMPs are probed at hadron collider experiments […]
Kavli Affiliate: Gary A. Steele | First 5 Authors: Byoung-moo Ann, Wouter Kessels, Gary. A. Steele, , | Summary: Driving quantum systems periodically in time plays an essential role in the coherent control of quantum states. The rotating wave approximation (RWA) is a good approximation technique for weak and nearly-resonance driven fields. However, these experiments […]
Kavli Affiliate: Ran Wang | First 5 Authors: Haojing Shen, Sihong Chen, Ran Wang, Xizhao Wang, | Summary: In this paper, we propose a defence strategy to improve adversarial robustness by incorporating hidden layer representation. The key of this defence strategy aims to compress or filter input information including adversarial perturbation. And this defence strategy […]
Kavli Affiliate: Peter W. Graham | First 5 Authors: Michael A. Fedderke, Peter W. Graham, Surjeet Rajendran, , | Summary: The gravitational coupling of nearby massive bodies to test masses in a gravitational wave (GW) detector cannot be shielded, and gives rise to ‘gravity gradient noise’ (GGN) in the detector. In this paper we show […]
Kavli Affiliate: Michael Zucker | First 5 Authors: Weixiang Jin, Michael Zucker, Arnd Pralle, , | Summary: Some anesthetics bind and potentiate gamma-aminobutyric-acid-type receptors, but no universal mechanism for general anesthesia is known. Furthermore, often encountered complications such as anesthesia induced amnesia are not understood. General anesthetics are hydrophobic molecules easily dissolving into lipid bilayers. […]
