RapidPIV: Full Flow-Field kHz PIV for Real-Time Display and Control

Kavli Affiliate: Morteza Gharib | First 5 Authors: Scott A. Bollt, Samuel H. Foxman, Morteza Gharib, , | Summary: We present a novel architecture for accelerating PIV calculations. An optical flow hardware accelerator does the brunt of the work, with cross-correlation only providing quick corrections. The result is RapidPIV: a free-to-download software program for real-time […]

Efficient and wavelength-tunable second-harmonic generation towards the green gap

Kavli Affiliate: Kerry Vahala | First 5 Authors: Zhiquan Yuan, Jinhao Ge, Peng Liu, Bohan Li, Mingxiao Li | Summary: Achieving compact and efficient visible laser sources is crucial for a wide range of applications. However traditional semiconductor laser technology faces difficulties in producing high-brightness green light, leaving a green gap in wavelength coverage. Second-harmonic […]

The Discriminant Power of Bubble Wall Velocities: Gravitational Waves and Electroweak Baryogenesis

Kavli Affiliate: Marcela Carena | First 5 Authors: Marcela Carena, Aurora Ireland, Tong Ou, Isaac R. Wang, | Summary: A precise determination of the bubble wall velocity $v_w$ is crucial for making accurate predictions of the baryon asymmetry and gravitational wave (GW) signals in models of electroweak baryogenesis (EWBG). Working in the local thermal equilibrium […]

Long-term stable nonlinear evolutions of ultracompact black-hole mimickers

Kavli Affiliate: Ulrich Sperhake | First 5 Authors: Gareth Arturo Marks, Seppe J. Staelens, Tamara Evstafyeva, Ulrich Sperhake, | Summary: We study the stability of ultracompact boson stars admitting light rings combining a perturbative analysis with 3+1 numerical-relativity simulations with and without symmetry assumptions. We observe excellent agreement between all perturbative and numerical results which […]

Operational experience and performance of the Silicon Vertex Detector after the first long shutdown of Belle II

Kavli Affiliate: T. Higuchi | First 5 Authors: K. Ravindran, K. Adamczyk, H. Aihara, S. Bacher, S. Bahinipati | Summary: In 2024, the Belle II experiment resumed data taking after the Long Shutdown 1, which was required to install a two-layer pixel detector and upgrade accelerator components. We describe the challenges of this shutdown and […]

Premature supermassive black hole mergers in cosmological simulations of structure formation

Kavli Affiliate: Debora Sijacki | First 5 Authors: Stephanie Buttigieg, Debora Sijacki, Christopher J. Moore, Martin A. Bourne, | Summary: The co-evolution of massive black holes (BHs) and their host galaxies is well-established within the hierarchical galaxy formation paradigm. Large-scale cosmological simulations are an ideal tool to study the repeated BH mergers, accretion and feedback […]

Sweeps in space: leveraging geographic data to identify beneficial alleles in Anopheles gambiae

Kavli Affiliate: Scott Small | Authors: Clara T Rehmann, Scott T Small, Peter L Ralph and Andrew D. Kern | Summary: As organisms adapt to environmental changes, natural selection modifies the frequency of non-neutral alleles. For beneficial mutations, the outcome of this process may be a selective sweep, in which an allele rapidly increases in […]
