From Ponzi Schemes to Benign Investment Dynamics: modelling Collapse, Stability, and a Path to Sustainability
Bernhard R. Parodi
The population and capital dynamics of three stylized investment systems are mathematically described using discrete-time difference equations with closed-form solutions. The model…
A generalized Fibonacci spiral
Bernhard R. Parodi
As a generalization of planar Fibonacci spirals that are based on the recurrence relation , we draw assembled spirals stemming from analytic solutions of the r…
Structure-dynamics relations for late-type spiral and dwarf irregular galaxies revisited
Bernhard R. Parodi
Scaling relations among structural and kinematical features of 79 late-type spiral and dwarf irregular galaxies of the SPARC sample are revisited or newly established. The mean cen…
Distribution of star-forming complexes in dwarf irregular galaxies
B. R. Parodi, B. Binggeli
We study the distribution of bright star-forming complexes in a homogeneous sample of 72 late-type (``irregular'') dwarf galaxies located within the 10 Mpc volume. Star-forming com…
Supernova type Ia luminosities, their dependence on second parameters, and the value of H_0
B. R. Parodi, A. Saha, A. Sandage +1
A sample of 35 SNe Ia with good to excellent photometry in B and V, minimum internal absorption, and 1200 < v < \approx 30000 km/s is compiled from the literature. As far as their…
The Status of the Distance Scale
G. A. Tammann, B. R. Parodi, B. Reindl
Cepheids are the pillar of the extragalactic distance scale, but their reach in distance is not sufficient to calibrate H_0. Yet HST has provided Cepheid distances to eight galaxie…
