Line Polarization of Si II 6355 Å in Type Ia Supernovae: A New Statistical Approach to Probe the Explosion Physics and Diversity
Aleksandar Cikota, Peter Hoeflich, Dietrich Baade +6
Spectropolarimetry provides a unique probe of ejecta asphericities, offering direct insights into the underlying explosion physics of Type Ia supernovae (SNe Ia). We analyze the st…
An axisymmetric shock breakout indicated by prompt polarized emission from the type II supernova 2024ggi
Yi Yang, Xudong Wen, Lifan Wang +18
The death of massive stars is triggered by an infall-induced bounce shock that disrupts the star. How such a shock is launched and propagates through the star is a decade-long puzz…
Moonlit sky polarization patterns from Cerro Paranal
B. Pereira, S. Gonzalez-Gaitan, A. M. Mourao +5
We investigate the polarization patterns from the moonlit sky as observed from the European Southern Observatory at Cerro Paranal. The moonlit sky background can be significant in…
Revisiting the unification of tidal disruption events with polarimetry
H. C. I. Wichern, G. Leloudas, M. Pursiainen +10
Tidal disruptions of stars by supermassive black holes produce multi-wavelength emission, of which the optical emission is of ambiguous origin. A unification scenario of tidal disr…
