Kavli Affiliate: Mihoko Nojiri | First 5 Authors: Keisuke Fujii, Christophe Grojean, Michael E. Peskin, Tim Barklow, Yuanning Gao | Summary: To aid contributions to the Snowmass 2021 US Community Study on physics at the International Linear Collider and other proposed $e^+e^-$ colliders, we present a list of study questions that could be the basis […]
Kavli Affiliate: Eric Peng | First 5 Authors: Jeremy Fensch, Pierre-Alain Duc, Sungsoon Lim, Éric Emsellem, Michal Bílek | Summary: Stellar shells around galaxies could provide precious insights into their assembly history. However, their formation mechanism remains poorly empirically constrained, in particular the type of galaxy collisions at their origin. We present MUSE@VLT data of […]
Kavli Affiliate: Risa Wechsler | First 5 Authors: Catherine E. Fielder, Yao-Yuan Mao, Andrew R. Zentner, Jeffrey A. Newman, Hao-Yi Wu | Summary: Cold dark matter haloes consist of a relatively smooth dark matter component as well as a system of bound subhaloes. It is the prevailing practice to include all halo mass, including mass […]
Kavli Affiliate: Boris I. Shraiman | First 5 Authors: Farzan Vafa, Mark J. Bowick, M. Cristina Marchetti, Boris I. Shraiman, | Summary: Recent experiments and numerical studies have drawn attention to the dynamics of active nematics. Two-dimensional active nematics flow spontaneously and exhibit spatiotemporal chaotic flows with proliferation of topological defects in the nematic texture. […]

Kavli Affiliate: Bruce Macintosh | First 5 Authors: Ji Wang, Jason Wang, Bo Ma, Jeffrey Chilcote, Steve Ertel | Summary: Comparing chemical abundances of a planet and the host star reveals the origin and formation path. Stellar abundance is measured with high-resolution spectroscopy. Planet abundance, on the other hand, is usually inferred from low-resolution data. […]
Kavli Affiliate: Joshua Frieman | First 5 Authors: Qian Yang, Yue Shen, Xin Liu, Michel Aguena, James Annis | Summary: The size of the dust torus in Active Galactic Nuclei (AGN) and their high-luminosity counterparts, quasars, can be inferred from the time delay between UV/optical accretion disk continuum variability and the response in the mid-infrared […]
Kavli Affiliate: Anthony Challinor | First 5 Authors: Antón Baleato Lizancos, Anthony Challinor, Julien Carron, , | Summary: Searches for the imprint of primordial gravitational waves in degree-scale CMB $B$-mode polarisation data must account for significant contamination from gravitational lensing. Fortunately, the lensing effects can be partially removed by combining high-resolution $E$-mode measurements with an […]
Kavli Affiliate: Ke Wang | First 5 Authors: Yizhen Wang, Mohannad Alhanahnah, Ke Wang, Mihai Christodorescu, Somesh Jha | Summary: Source code attribution approaches have achieved remarkable accuracy thanks to the rapid advances in deep learning. However, recent studies shed light on their vulnerability to adversarial attacks. In particular, they can be easily deceived by […]
