Juliana Saponara Colloquium: Investigation of galaxies by means of HI observations
Observations of neutral Hydrogen are an excellent tool for studying interactions between galaxies or between galaxies and their environment. The 21cm HI line provides spatial as well as kinematic information of the HI gas. In this talk, I will show you some of the studies I have carried out during my PhD. In particular, I will focus on the debris we observed in the IC 1459 galaxy group using ATCA data and the results that we obtained using GMRT observations of a certain faint dwarf galaxy, KK 69. The question we want to address is: Is this galaxy evolving from a dwarf gas-rich (dwarf irregular) to a dwarf gas-poor (dwarf spheroidal) galaxy?
