Kavli Affiliate: T. Higuchi | First 5 Authors: M. C. Lucas-Estañ, B. Coll-Perales, T. Shimizu, J. Gozalvez, T. Higuchi | Summary: 5G has been designed to support applications such as connected and automated driving. To this aim, 5G includes a highly flexible New Radio (NR) interface that can be configured to utilize different subcarrier spacings […]
Kavli Affiliate: T. Higuchi | First 5 Authors: B. Coll-Perales, M. C. Lucas-Estañ, T. Shimizu, J. Gozalvez, T. Higuchi | Summary: 5G networks provide higher flexibility and improved performance compared to previous cellular technologies. This has raised expectations on the possibility to support advanced V2X services using the cellular network via Vehicle-to-Network (V2N) and V2N2V […]
Kavli Affiliate: Jia Liu | First 5 Authors: Benjamin Remy, Francois Lanusse, Niall Jeffrey, Jia Liu, Jean-Luc Starck | Summary: Weak lensing mass-mapping is a useful tool to access the full distribution of dark matter on the sky, but because of intrinsic galaxy ellipticies and finite fields/missing data, the recovery of dark matter maps constitutes […]
Kavli Affiliate: David N. Spergel | First 5 Authors: Andrina Nicola, Francisco Villaescusa-Navarro, David N. Spergel, Jo Dunkley, Daniel Anglés-Alcázar | Summary: Uncertain feedback processes in galaxies affect the distribution of matter, currently limiting the power of weak lensing surveys. If we can identify cosmological statistics that are robust against these uncertainties, or constrain these […]
Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Nick Ekanger, Mukul Bhattacharya, Shunsaku Horiuchi, , | Summary: We study the nucleosynthesis products in neutrino-driven winds from rapidly rotating, highly magnetised and misaligned protomagnetars using the nuclear reaction network SkyNet. We adopt a semi-analytic parameterized model for the protomagnetar and systematically study the capabilities of its […]
Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Sayan Mandal, Neelima Sehgal, Toshiya Namikawa, , | Summary: The origin of the $mumathrm{G}$ magnetic fields observed in galaxies is unknown. One promising scenario is that magnetic fields generated during inflation, larger than 0.1 $mathrm{nG}$ on Mpc scales, were adiabatically compressed to $mumathrm{G}$ strengths in galaxies during […]
Kavli Affiliate: David N. Spergel | First 5 Authors: Francisco Villaescusa-Navarro, Jupiter Ding, Shy Genel, Stephanie Tonnesen, Valentina La Torre | Summary: Galaxies can be characterized by many internal properties such as stellar mass, gas metallicity, and star-formation rate. We quantify the amount of cosmological and astrophysical information that the internal properties of individual galaxies […]
Kavli Affiliate: David N. Spergel | First 5 Authors: Digvijay Wadekar, Leander Thiele, Francisco Villaescusa-Navarro, J. Colin Hill, Miles Cranmer | Summary: Complex systems (stars, supernovae, galaxies, and clusters) often exhibit low scatter relations between observable properties (e.g., luminosity, velocity dispersion, oscillation period, temperature). These scaling relations can illuminate the underlying physics and can provide […]
Kavli Affiliate: David N. Spergel | First 5 Authors: Francisco Villaescusa-Navarro, Shy Genel, Daniel Anglés-Alcázar, Lucia A. Perez, Pablo Villanueva-Domingo | Summary: The Cosmology and Astrophysics with MachinE Learning Simulations (CAMELS) project was developed to combine cosmology with astrophysics through thousands of cosmological hydrodynamic simulations and machine learning. CAMELS contains 4,233 cosmological simulations, 2,049 N-body […]
Kavli Affiliate: Misao Sasaki | First 5 Authors: Yi-Fu Cai, Xiao-Han Ma, Misao Sasaki, Dong-Gang Wang, Zihan Zhou | Summary: We report a novel prediction from single-field inflation that even a tiny step in the inflaton potential can change our perception of primordial non-Gaussianities of the curvature perturbation. Our analysis focuses on the tail of […]
