The MandelZoom project I: modelling black hole accretion through an $α$-disc in dwarf galaxies with a resolved interstellar medium

Posted by dbos Cambridge

Kavli Affiliate: Debora Sijacki | First 5 Authors: Eun-jin Shin, Debora Sijacki, Matthew C. Smith, Martin A. Bourne, Sophie Koudmani | Summary: While mounting observational evidence suggests that intermediate mass black holes (IMBHs) may be important in shaping the properties of dwarf galaxies both at high redshifts and in the local Universe, our theoretical understanding […]

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

Posted by dbos Caltech

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

Posted by dbos Caltech

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

Posted by dbos Chicago

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

Posted by dbos Cambridge

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

Posted by dbos Tokyo

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

Posted by dbos Cambridge

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 […]
