Early Light Curve Excess in Type IIb Supernovae Observed by the ATLAS Survey: Qualitative Constraints on Progenitor Systems
Bastian Ayala, Joseph P. Anderson, G. Pignata +8
Type IIb supernovae (SNe IIb) often exhibit an early light curve excess (EE) preceding the main peak powered by radioactive nickel decay. The physical origin of this early emission…

The Milky Way accretion history compared to cosmological simulations -- from bulge to dwarf galaxy infall
F. Hammer, Y. J. Jiao, G. A. Mamon +6
Galactic halos are known to grow hierarchically, inside out. This implies a correlation between the infall lookback time of satellites and their binding energy. Cosmological simula…

Out of equilibrium response and fluctuation-dissipation violations across scales in flocking systems
Federica Ferretti, Irene Giardina, Tomas Grigera +2
Flocking systems are known to be strongly out of equilibrium. Energy input occurs at the individual level to ensure self-propulsion, and the individual motility in turn contributes…
