With Chandra we can look deep into galaxies and separate, spatially and spectrally, the components of the X-ray emission. This talk will focus on two galaxies: the Antennae galaxies as a prototype of tidally interacting galaxies, and NGC 5128/Centaurus-A, as an example of late merger. Chandra observations of the Antennae have revealed a rich population of Ultra Luminous X-ray sources (ULX), as well as a complex and luminous hot interstellar medium. With these data, and by comparing them with a range of multi-wavelength information, we can begin to understand the nature of ULXs, and have a direct picture of the complex multi-phase ISM. NGC 5128 offers a detailed look at a merger remnant. A recent Chandra discovery in this complex galaxy is the presence of giant arcs of hot gas, that seem to be related with some of the stellar shells of this system.
