Kavli Affiliate: Emil J. Martinec | First 5 Authors: Emil J. Martinec, Emil J. Martinec, , , | Summary: Supergravity solutions describing supersymmetric rotating bound states of NS fivebranes, fundamental strings and momentum can sometimes have an ergoregion but no horizon. In such supersymmetric ergoregions, there is an unusual feature that there exist BPS "excitations" […]
Kavli Affiliate: Chiara Daraio | First 5 Authors: Manas Bhargava, Manas Bhargava, , , | Summary: Natural organisms utilize distributed actuation through their musculoskeletal systems to adapt their gait for traversing diverse terrains or to morph their bodies for varied tasks. A longstanding challenge in robotics is to emulate this capability of natural organisms, which […]

Kavli Affiliate: Erin Kara | First 5 Authors: XRISM Collaboration, XRISM Collaboration, , , | Summary: We present results from XRISM/Resolve observations of the core of the galaxy cluster Abell 2319, focusing on its kinematic properties. The intracluster medium (ICM) exhibits temperatures of approximately 8 keV across the core, with a prominent cold front and […]

Kavli Affiliate: Harry A. Atwater | First 5 Authors: Matthew F. Campbell, Matthew F. Campbell, , , | Summary: Achieving laser-driven, reflective, relativistic light sails would represent a tremendous breakthrough for humankind, allowing us to advance our understanding of the solar system and deep space far beyond what we know from space probes, telescopes, and […]
Kavli Affiliate: Eric Miller | First 5 Authors: Arnab Sarkar, Arnab Sarkar, , , | Summary: We present $sim$500 ks XRISM observations covering the central and two northern regions of the Abell 2029 galaxy cluster. Resolve enables us to distinguish multiple emission lines from hydrogen-like and helium-like iron (Fe) ions. This study focuses on the […]

Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Yuji Tachikawa, Yuji Tachikawa, , , | Summary: We construct a new invariant of two-dimensional $mathcalN=(0,1)$ supersymmetric quantum field theories (SQFTs), under a couple of assumptions on the general properties of such SQFTs motivated by considerations in heterotic string theory. This new invariant is in addition to […]
Kavli Affiliate: Nicola Omodei | First 5 Authors: Ildar Khabibullin, Ildar Khabibullin, , , | Summary: Extended X-ray emission observed in the direction of several molecular clouds in the Central Molecular Zone (CMZ) of our Galaxy exhibits spectral and temporal properties consistent with the `X-ray echo’ scenario. It postulates that the observed signal is a […]
