Rayleigh wave propagation in nonlinear metasurfaces

Posted by Caltech

Kavli Affiliate: Chiara Daraio | First 5 Authors: Antonio Palermo, Behrooz Yousefzadeh, Chiara Daraio, Alessandro Marzani, | Summary: We investigate the propagation of Rayleigh waves in a half-space coupled to a nonlinear metasurface. The metasurface consists of an array of nonlinear oscillators attached to the free surface of a homogeneous substrate. We describe, analytically and […]

Modelling correlated variability in accreting black holes: the effect of high density and variable ionisation on reverberation lags

Posted by klaurent MIT

Kavli Affiliate: Erin Kara | First 5 Authors: Guglielmo Mastroserio, Adam Ingram, Jingyi Wang, Javier A. García, Michiel van der Klis | Summary: We present a new release of the RELTRANS model to fit the complex cross-spectrum of accreting black holes as a function of energy. The model accounts for continuum lags and reverberation lags […]
