WebThe mass spectrum of stellar-mass black holes (BHs) is highly uncertain. Dynamical mass measurements are available only for few ($\sim{}10$) BHs in X-ray binaries, while theoretical models strongly depend on the hydrodynamics of supernova (SN) explosions and on the evolution of massive stars. In this paper, we present and discuss the mass spectrum of … WebJan 15, 2013 · The prediction accuracy of the respective PLSR-model was lower compared to Bruker MPA based BMP FM estimates, despite of its broader available spectral wavelength range. This demonstrates that for BMP retrieval a high SNR and spectral resolution is more important than including the VIS spectral region in the analysis. meow movie cast
