Development and testing of integrated readout electronics for next generation SiSeRO (Single electron Sensitive Read Out) devices

Posted by klaurent MIT

Kavli Affiliate: Marshall Bautz | 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 (ENC) of 3.2 electrons root mean square (RMS), and a full […]

The high-speed X-ray camera on AXIS: design and performance updates

Posted by klaurent MIT

Kavli Affiliate: Marshall Bautz | 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 greatly increase the X-ray throughput per unit mass; and to the detector system, […]

Multiwavelength Observations of the Apparently Non-repeating FRB 20250316A

Posted by klaurent Peking

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 […]

Narrowing the discovery space of the cosmological 21-cm signal using multi-wavelength constraints

Posted by klaurent Cambridge

Kavli Affiliate: George Efstathiou | 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. Here, we constrain the 21-cm signal and infer IGM properties using the Population II galaxy parameters derived […]

Benchmarking spike source localization algorithms in high density probes

Posted by klaurent Tokyo

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 […]

Robust Live Streaming over LEO Satellite Constellations: Measurement, Analysis, and Handover-Aware Adaptation

Posted by klaurent Berkeley

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 […]

Overcoming Latency Bottlenecks in On-Device Speech Translation: A Cascaded Approach with Alignment-Based Streaming MT

Posted by klaurent Stanford

Kavli Affiliate: Zeeshan Ahmed | Summary:This paper tackles several challenges that arise when integrating Automatic Speech Recognition (ASR) and Machine Translation (MT) for real-time, on-device streaming speech translation. Although state-of-the-art ASR systems based on Recurrent Neural Network Transducers (RNN-T) can perform real-time transcription, achieving streaming translation in real-time remains a significant challenge. To address this […]

Probing Purely Inelastic Scalar Dark Matter Across Colliders and Gravitational Wave Observatories

Posted by klaurent Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Jinhui Guo, Jinhui Guo, , , | Summary: We propose and study a purely inelastic scalar dark matter model, where two real scalars-dark matter $phi_1$ and its excited partner $phi_2$ interact with the Standard Model via a Higgs portal. After mass diagonalization, only inelastic couplings remain, allowing […]
