Kavli Affiliate: Lile Wang |Summary:Feedback from massive stars regulates the formation of next-generation stars and planets and thus shapes the evolution of galaxies, yet observational evidence capable of determining which mechanism dominates the feedback process has long been lacking. Here,we present a large-scale HI survey toward Orion A$.$ With an unprecedented sensitivity and superior resolution, […]
Kavli Affiliate: Sarah Woolley | Authors: Mila Bertolo, Daniel Müllensiefen, Isabelle Peretz, Sarah C. Woolley, Jon T. Sakata and Samuel A. Mehr | Summary: Since Darwin, researchers have proposed that human musicality evolved in a reproductive context in which males produce music to signal their mate quality to females. Sexually selected traits result from sex […]
Kavli Affiliate: Daniel Kronauer | Authors: Daniel H. Pastor, Leonora Olivos-Cisneros, Alejandra Hurtado-Giraldo, Anurag Sharma, Patrick K. Piekarski, Giacomo L. Glotzer and Daniel Kronauer | Summary: Ant larvae are blind and immobile, depending heavily on the adults for care in the form of feeding, grooming, and transport. However, they are not inactive colony members but […]
Kavli Affiliate: Michael J Higley | Authors: Yongxu Zhang, Josue Ortega Caro, Rachel Oren, Michael James Higley, Jessica Cardin, Anne Churchland and Shreya Saxena | Summary: Modern recording technologies enable simultaneous measurement of high-dimensional neural activity and rich behavioral variables, creating both an opportunity and a modeling challenge: identifying the shared latent structure that mediates […]
Kavli Affiliate: David W. Miller | Summary:Gaia has substantially expanded the sample of candidate white dwarfs (WDs) in open clusters, but many remain without spectroscopic characterization. We leverage the increasingly extensive archives of large public spectroscopic surveys to identify 62 candidate cluster WDs with available spectra from DESI, LAMOST, and SDSS. After discarding sources with […]
Kavli Affiliate: Linhua Jiang | Summary:Emission-line galaxies provide key diagnostics of star formation, chemical enrichment, and AGN activity across cosmic time. We present a systematic census of emission-line sources using JWST/NIRCam wide-field slitless spectroscopy (WFSS) from the COSMOS-3D program, which covers a large contiguous area of 0.33 deg$^2$ and provides F444W grism spectroscopy over $3.9$–$5.1 […]
Kavli Affiliate: Anthony Lasenby | Summary:We investigate the local gravitational source and charges obtained by introducing translations as an internal Stückelberg redundancy in Weyl gauge theory. The internal-$T(4)$-invariant dressed coframe identifies the source of the translational potential with the existing coframe variational derivative, without introducing new dynamics. We derive an excitation/source equation and balance law […]
Kavli Affiliate: Anthony Lasenby | Summary:We consider whether the translation Noether current of a linearised metric spin-2 theory admits a strictly gauge-invariant local representative. For Fierz-Pauli and dynamically regular pure curvature-squared theories in four dimensions, we show that no such representative exists under the stated locality, polynomiality and covariance assumptions. A direct enumeration first excludes […]
Kavli Affiliate: Wei Gao| Summary:In the investigation of the "knee" region within the cosmic ray energy spectrum, extensive air shower (EAS) reconstruction by using different EAS secondary particles are of paramount importance for energy determination and composition separation and finally measurement of energy spectrum of different cosmic ray composition. The Electron-Neutron Detector Array (ENDA) is […]
Kavli Affiliate: Savdeep Sethi | Summary:We study warped compactifications of eleven-dimensional supergravity on eight-manifolds to Minkowski or AdS vacua preserving $N=1$ supersymmetry in three dimensions. For backgrounds characterised by a local G$_2$ structure, we derive an off-shell real superpotential functional in terms of the internal geometry and fluxes without performing a finite Kaluza-Klein truncation. We […]
