Kavli Affiliate: David Charbonneau | First 5 Authors: Matthew C. H. Leung, Matthew C. H. Leung, , , | Summary: An increasing number of applications in exoplanetary science require spectrographs with high resolution and high throughput without the need for a broad spectral range. Examples include the search for biosignatures through the detection of the […]
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 […]
Kavli Affiliate: Erin Kara | First 5 Authors: Joheen Chakraborty, Joheen Chakraborty, , , | Summary: Quasi-Periodic Eruptions (QPEs) are luminous, recurring X-ray outbursts from galactic nuclei, with timescales of hours to days. While their origin remains uncertain, leading models invoke accretion disk instabilities or the interaction of a massive black hole (MBH) with a […]
Kavli Affiliate: D. B. Macfarlane | First 5 Authors: M. F. Albakry, M. F. Albakry, , , | Summary: SuperCDMS SNOLAB uses kilogram-scale germanium and silicon detectors to search for dark matter. Each detector has Transition Edge Sensors (TESs) patterned on the top and bottom faces of a large crystal substrate, with the TESs electrically […]
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 […]
Kavli Affiliate: Susan E. Clark | First 5 Authors: Marta Nowotka, Marta Nowotka, , , | Summary: We present a joint analysis of HI absorption Zeeman measurements and the morphology of filamentary HI emission to investigate the three-dimensional structure of the magnetic field in the diffuse neutral interstellar medium (ISM). Our analysis is based on […]
Kavli Affiliate: Simon Groblacher | First 5 Authors: , , , , | Summary: Superfluid helium is a prototypical quantum liquid. As such, it has been a prominent platform for the study of quantum many body physics. More recently, the outstanding mechanical and optical properties of superfluid helium, such as low mechanical dissipation and low […]
Kavli Affiliate: David A. Muller | First 5 Authors: Yixin Li, Yixin Li, , , | Summary: Differentiable rendering has been widely adopted in computer graphics as a powerful approach to inverse problems, enabling efficient gradient-based optimization by differentiating the image formation process with respect to millions of scene parameters. Inspired by this paradigm, we […]
Kavli Affiliate: Yukinobu Toda | First 5 Authors: Tudor Pădurariu, Tudor Pădurariu, , , | Summary: We introduce limit categories for cotangent stacks of smooth stacks as an effective version of classical limits of categories of D-modules on them. We develop their general theory and pursue their relation with categories of D-modules. In particular, we […]
Kavli Affiliate: Long Zhang | First 5 Authors: Yang Sun, Yang Sun, , , | Summary: Retrieval-augmented generation (RAG) incorporates external knowledge into large language models (LLMs), improving their adaptability to downstream tasks and enabling information updates. Surprisingly, recent empirical evidence demonstrates that injecting noise into retrieved relevant documents paradoxically facilitates exploitation of external knowledge […]
