Kavli Affiliate: Marshall W. Bautz | First 5 Authors: Haley R. Stueber, Haley R. Stueber, , , | Summary: Future strategic X-ray missions, such as the Advanced X-ray Imaging Satellite (AXIS) and those targeted by the Great Observatories Maturation Program (GOMaP), require fast, low-noise X-ray imaging spectrometers. To achieve the speed and noise capabilities required […]
Kavli Affiliate: Gregory Prigozhin | First 5 Authors: Tanmoy Chattopadhyay, Tanmoy Chattopadhyay, , , | Summary: The first generation of Single electron Sensitive Read Out (SiSeRO) amplifiers, employed as on-chip charge detectors for charge-coupled devices (CCDs) have demonstrated excellent noise and spectral performance: a responsivity of around 800 pA per electron, an equivalent noise charge […]
Kavli Affiliate: Robert Goeke | First 5 Authors: Eric D. Miller, Eric D. Miller, , , | Summary: AXIS, a Probe mission concept now in a Phase A study, will provide transformative studies of high-energy astrophysical phenomena thanks to its high-resolution X-ray spectral imaging. These capabilities are enabled by improvements to the mirror design that […]
Kavli Affiliate: Jing Wang | First 5 Authors: Ye Li, Ye Li, , , | Summary: The physical origin of fast radio bursts (FRBs) remains uncertain. Although multiwavelength observations offer critical diagnostics and have been widely conducted, only Galactic FRB~20200428D is associated with an X-ray burst from the magnetar SGR J1935+2154. Here, we present multiwavelength […]
Kavli Affiliate: George Efstathiou | First 5 Authors: Jiten Dhandha, Jiten Dhandha, , , | Summary: The cosmic 21-cm signal is a promising probe of the early Universe, owing to its sensitivity to the thermal state of the neutral intergalactic medium (IGM) and properties of the first luminous sources. In this work, we constrain the […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: , , , , | Summary: Broad absorption line (BAL) quasars are often considered X-ray weak relative to their optical/UV luminosity, whether intrinsically (i.e., the coronal emission is fainter) or due to large column densities of absorbing material. The SDSS-V is providing optical spectroscopy for samples of […]
Kavli Affiliate: Long Zhang | First 5 Authors: Yin Yang, Yin Yang, , , | Summary: We develop a quantum algorithm for linear algebraic equations Ax=b from the perspective of Schr"odingerization-form problems, which are characterized by a system of linear convection equations in one higher dimension. When A is positive definite, the solution x can […]
Kavli Affiliate: Leon Balents | First 5 Authors: Tarun Advaith Kumar, Tarun Advaith Kumar, , , | Summary: A variety of generative neural networks recently adopted from machine learning have provided promising strategies for studying quantum matter. In particular, the success of autoregressive models in natural language processing has motivated their use as variational ans"atze, […]
Kavli Affiliate: Jia Liu | First 5 Authors: Hao Zhao, Hao Zhao, , , | Summary: Estimating neuron location from extracellular recordings is essential for developing advanced brain-machine interfaces. Accurate neuron localization improves spike sorting, which involves detecting action potentials and assigning them to individual neurons. It also helps monitor probe drift, which affects long-term […]
Kavli Affiliate: Feng Wang | First 5 Authors: Hao Fang, Hao Fang, , , | Summary: Live streaming has experienced significant growth recently. Yet this rise in popularity contrasts with the reality that a substantial segment of the global population still lacks Internet access. The emergence of Low Earth orbit Satellite Networks (LSNs), such as […]
