Recent results from Hubble Space Telescope (HST) have resolved starbursts as collections of compact young stellar clusters. Here we present a photometric catalogue of the young stellar clusters in the nuclear starburst of M82, observed with the HST WFPC2 in Hα (F656N) and in four optical broad-band filters. We identify 197 young super stellar clusters. The… (More)
We study the far-infrared emission properties of the nearby starburst galaxy NGC 253 based on IRAS maps and an ISOPHOT map at 180 µm. Based on the analysis of the light profiles, we have been able to identify three main structural components: an unresolved nuclear component, an exponential disk, and a kiloparsec scale bar. In addition, we also found a ring… (More)
This paper describes an application of the object-oriented paradigm to the construction of AlgoDeGrafos, a graph-theoretical system enabling the use of graph algorithms. This system is freely available for academic purposes and can be used as a support in courses on graph theory algorithms.
The starburst galaxy M82 shows a system of Hα-emitting filaments which extend to each side of the galactic disk. We model these filaments as the result of the interaction between the winds from a distribution of Super Stellar Clusters (SSCs). We first derive the condition necessary for producing a radiative interaction between the cluster winds (a condition… (More)
