Collective Normal Modes of Ensembles of Magnetic Tubes: Applications to Coronal Arcades and Multi-Stranded Loops
Using the T-matrix theory, we have performed an analytical study of the collective fast normal modes of an arbitrary system of loops. The obtained results allow...
Colliding galaxies and the rapid assembly of clouds into proto-super star clusters
We present a short summary of several 2D hydrodynamic calculations that suggest that upon the collision of galaxies two physical mechanisms lead to the...
Collisional Enhancement of H I Lines in Ionized Nebulae
Collisional excitation of neutral hydrogen atoms can significantly increase the intensity of Balmer lines with respect to pure recombination. If this effect is...
Color-Magnitude Diagrams, Probabilistic Synthesis Models and the Upper Mass Limit of the Initial Mass Function
We present the underlying relations between color-magnitude diagrams (CMDs) and synthesis models through the use of stellar luminosity distribution functions...
Colors of intermediate z bulges in the GOYA survey
The chronology of bulge and disk formation is a major unsolved issue in galaxy formation, which impacts on our global understanding of the Hubble sequence. We...
