Revealing the formation mechanism of the shell galaxy NGC474 with MUSE

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 […]

Illuminating Dark Matter Halo Density Profiles Without Subhaloes

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 […]

Robust and Accurate Authorship Attribution via Program Normalization

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 […]

The Coronal Global Evolutionary Model: Using HMI Vector Magnetogram and Doppler Data to Determine Coronal Magnetic Field Evolution

Kavli Affiliate: J. Todd Hoeksema | Summary:The Coronal Global Evolutionary Model (CGEM) provides data-driven simulations of the magnetic field in the solar corona to better understand the build-up of magnetic energy that leads to eruptive events. The CGEM project has developed six capabilities. CGEM modules (1) prepare time series of full-disk vector magnetic field observations […]

TOI 694 b and TIC 220568520 b: Two Low-Mass Companions Near the Hydrogen Burning Mass Limit Orbiting Sun-like Stars

Kavli Affiliate: Gabor Furesz | First 5 Authors: Ismael Mireles, Avi Shporer, Nolan Grieves, George Zhou, Maximilian N. Günther | Summary: We report the discovery of TOI 694 b and TIC 220568520 b, two low-mass stellar companions in eccentric orbits around metal-rich Sun-like stars, first detected by the Transiting Exoplanet Survey Satellite (TESS). TOI 694 […]

Thermal Instability in the CGM of $L_{star}$ Galaxies: Testing “Precipitation” Models with the FIRE Simulations

Kavli Affiliate: Andrey V. Kravtsov | First 5 Authors: Clarke J. Esmerian, Andrey V. Kravtsov, Zachary Hafen, Claude-Andre Faucher-Giguere, Eliot Quataert | Summary: We examine the thermodynamic state and cooling of the low-$z$ Circum-Galactic Medium (CGM) in five FIRE-2 galaxy formation simulations of Milky Way-mass galaxies. We find that the CGM in these simulations is […]

Precision Measurement of the Beam-Normal Single-Spin Asymmetry in Forward-Angle Elastic Electron-Proton Scattering

Kavli Affiliate: A. C. Davis | Summary:A beam-normal single-spin asymmetry generated in the scattering of transversely polarized electrons from unpolarized nucleons is an observable related to the imaginary part of the two-photon exchange process. We report a 2% precision measurement of the beam-normal single-spin asymmetry in elastic electron-proton scattering with a mean scattering angle of […]
