Beyond the Largest Lyapunov Exponent: Entropy-Based Diagnostics of Chaos in Henon-Heiles and N-Body Dynamics
Alessandro Alberto Trani, Pierfrancesco Di Cintio, Michele Ginolfi
The largest Lyapunov exponent is widely used to diagnose chaos in gravitational dynamics, but in mixed phase spaces and finite-N systems it does not always provide a complete descr…
The ALPINE-CRISTAL-JWST Survey: The Fast Metal Enrichment of Massive Galaxies at z~5
Andreas L. Faisst, Lun-Jun Liu, Yohan Dubois +54
We present the stellar mass-metallicity relation (MZR) and mass-metallicity-star formation relation ("fundamental metallicity relation"; FMR) of 18 massive (log(M/Msun) = 9.5 - 11)…
The ALPINE-CRISTAL-JWST Survey: Gas-phase abundance gradients of main sequence star-forming galaxies and their kinematics at
Lilian L. Lee, Natascha M. Förster Schreiber, Seiji Fujimoto +50
We present gas-phase radial metallicity profiles for 20 main-sequence galaxies at , primarily based on JWST NIRSpec IFU observations obtained as part of the JWST-ALPINE-CRIS…
Milky-Way-like stars in a galaxy core 8 billion years ago revealed by gravitational lensing
Quirino D'Amato, Filippo Mannucci, Alessandro Sonnenfeld +40
The assembly of stellar-dominated cores in elliptical galaxies is key to understanding how cosmic structures evolved. Gravitational lensing offers unique insights into the nature o…
Tracing nitrogen enrichment across cosmic time with JWST
E. Cataldi, F. Belfiore, M. Curti +22
We present a comprehensive analysis of the nitrogen-to-oxygen (N/O) abundance ratio in a sample of ~ 660 star-forming galaxies at redshift z ~ 1-6, with a median redshift of z = 3.…
The ALPINE-CRISTAL-JWST Survey: Chemical Abundance Comparison Between the ISM and CGM of Main-Sequence Galaxies at z=4-6
Wuji Wang, Andreas L. Faisst, Kyle Finner +37
Gaseous halos around galaxies play an important role in galaxy evolution. The exchange of metals from the interstellar medium (ISM) to the circumgalactic medium (CGM) are caused by…
