The first detection of cosmic-ray excited H$_2$ in interstellar space

Kavli Affiliate: Troy A. Porter | First 5 Authors: Shmuel Bialy, Shmuel Bialy, , , | Summary: Stars and planets form within cold, dark molecular clouds. In these dense regions, where starlight cannot penetrate, cosmic rays (CRs) are the dominant source of ionization — driving interstellar chemistry(Dalgarno (2006, PNAS, 103, 12269)), setting the gas temperature(Goldsmith […]

Experimental validation of photonic lantern imaging and wavefront sensing performance

Kavli Affiliate: Bruce Macintosh | First 5 Authors: Aditya R. Sengupta, Aditya R. Sengupta, , , | Summary: Photonic lanterns (PLs) are fiber-based waveguides that are capable of focal-plane wavefront sensing while simultaneously directing light to downstream science instruments. The optimal choice of wavefront reconstruction algorithm has yet to be determined, and likely depends on […]

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

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Zeeshan Ahmed, 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 […]

Quantum sensing of electron beams using solid-state spins

Kavli Affiliate: Robert L. Byer | First 5 Authors: Jakob M. Grzesik, Jakob M. Grzesik, , , | Summary: Scattering experiments with energetic particles, such as free electrons, have been historically used to reveal the quantum structure of matter. However, realizing coherent interactions between free-electron beams and solid-state quantum systems has remained out of reach, […]

Three dimensional magnetic reconnection mediated with plasmoids and the resulted multi-thermal emissions in the cool atmosphere of the Sun

Kavli Affiliate: Robert Cameron | First 5 Authors: Guanchong Cheng, Guanchong Cheng, , , | Summary: Flux emergence is ubiquitous in the Sun’s lower atmosphere, where the emerging magnetic flux can reconnect with the pre-existing magnetic field. We investigate plasmoid formation and the resulting multi-thermal emissions during three-dimensional magnetic reconnection in the lower solar atmosphere. […]
