A More General Model for the Intrinsic Scatter in Type Ia Supernova Distance Moduli
General Model Intrinsic Scatter Supernova Distance Moduli
2011/10/13
We describe a new formalism to fit the parameters $\alpha$ and $\beta$ that are used in the SALT2 model to determine the standard magnitudes of Type Ia supernovae. The new formalism describes the intr...
Disk Galaxy Scaling Relations in the SFI++: Intrinsic Scatter and Applications
galaxies spirals – galaxies fundamental parameters – galaxies
2010/11/15
We study the scaling relations between the luminosities, sizes, and rotation velocities of disk galaxies in the SFI++, with a focus on the size-luminosity (RL) and size-rotation velocity (RV ) relatio...
