MY LIFE AS TUTOR: Reflections on Two Recent Experiences
Alessandro B. Romeo
In this final report, I briefly reflect on two parallel teaching experiences as tutor. Besides, I briefly view such experiences in interaction with my research work, private life a…
Data compression on board the PLANCK Satellite Low Frequency Instrument: optimal compression rate
E. Gaztanaga, J. Barriga, A. Romeo +2
Data on board the future PLANCK Low Frequency Instrument (LFI), to measure the Cosmic Microwave Background (CMB) anisotropies, consist of differential temperature measurements,…
Modelling Gravity in N-Body Simulations of Disc Galaxies: Optimal Types of Softening for Given Dynamical Requirements
Alessandro B. Romeo
Modelling gravity is a fundamental problem that must be tackled in N-body simulations of stellar systems, and satisfactory solutions require a deep understanding of the dynamical e…
Dynamical Effects of Softening in N-Body Simulations of Disc Galaxies
Alessandro B. Romeo
Two questions that naturally arise in N-body simulations of stellar systems are: (1) How can we compare experiments that employ different types of softened gravity? (2) Given a par…
