The Influence of Cosmic Rays in the Circumnuclear Molecular Gas of NGC 1068,sing a time and depth dependent chemical model we reproduced the observational results, and show that the column densities of most of the species are better reproduced if the cold gas is heavily pervaded by a high cosmic ray ionization rate of about 1,000 times that of the Milky Way. We discuss how

Distribution of Cosmic-Ray Ionization Rates in the Galactic Diffuse Interstellar Medium as Inferred reactions responsible for generating many of the diatomic and small polyatomic molecules observed in the ISM. A few such species—OH., H.O., and H. in particular—are formed and destroyed by rather simple processes, making them powerful probes of the cosmic-ray ionization rate. At present, we have pe

Stellar Populations in the Galactic Center,of the different stellar tracers and focus our attention on the SFR based on the three classical Cepheids recently discovered in the Galactic Center. We also discuss stellar populations in field and cluster stars and present some preliminary results based on near-infrared photometry of a field cente

Evidence of Nuclear Disks from the Radial Distribution of CCSNe in Starburst Galaxies, by providing large amounts of dense molecular gas down to the central kiloparsec region. Several scenarios to drive the gas further down to the central ∼ 100 pc, have been proposed, including the formation of a nuclear disk around the black hole, where massive stars would produce supernovae. Here,
