Effective continuum models for the buckling of non-periodic architected sheets that display quasi-mechanism behaviors

Posted by Uncategorized

Kavli Affiliate: Chiara Daraio | First 5 Authors: Connor McMahan, Andrew Akerson, Paolo Celli, Basile Audoly, Chiara Daraio | Summary: In this work, we construct an effective continuum model for architected sheets that are composed of bulky tiles connected by slender elastic joints. Due to their mesostructure, these sheets feature quasi-mechanisms — low-energy local kinematic […]

Probing Relativistic Axions from Transient Astrophysical Sources

Posted by Tokyo

Kavli Affiliate: Yevgeny V. Stadnik | First 5 Authors: Joshua Eby, Satoshi Shirai, Yevgeny V. Stadnik, Volodymyr Takhistov, | Summary: Axions constituting dark matter (DM) are often considered to form a non-relativistic oscillating field. We explore bursts of relativistic axions from transient astrophysical sources, such as axion star explosions, where the sources are initially non-relativistic. […]

The Simons Observatory microwave SQUID multiplexing detector module design

Posted by Chicago

Kavli Affiliate: Jeffrey J. McMahon | First 5 Authors: Heather McCarrick, Erin Healy, Zeeshan Ahmed, Kam Arnold, Zachary Atkins | Summary: Advances in cosmic microwave background (CMB) science depend on increasing the number of sensitive detectors observing the sky. New instruments deploy large arrays of superconducting transition-edge sensor (TES) bolometers tiled densely into ever larger […]

Tuning acoustic impedance in load-bearing structures

Posted by Caltech

Kavli Affiliate: Chiara Daraio | First 5 Authors: Sai Sharan Injeti, Paolo Celli, Kaushik Bhattacharya, Chiara Daraio, | Summary: Acoustic transparency is the capability of a medium to transmit mechanical waves to adjacent media, without scattering. This characteristic can be achieved by carefully engineering the acoustic impedance of the medium — a combination of wave […]

GRUMPY: a simple framework for realistic forward-modelling of dwarf galaxies

Posted by Chicago

Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Andrey Kravtsov, Viraj Manwadkar, , , | Summary: We present a simple regulator-type framework designed specifically for modelling formation of dwarf galaxies. We explore sensitivity of model predictions for the stellar mass–halo mass and stellar mass–metallicity relations to different modelling choices and parameter values. Despite its simplicity, […]
