It is well known that the environment where a galaxy resides plays an important role in its formation and evolution. Galaxies in the MaNGA sample have many different morphologies. There are elliptical, lenticular, and spiral galaxies, but there are also peculiar galaxies such as dwarfs and mergers or interacting galaxies. There are also very bright and large galaxies, with many many stars, but MaNGA is also observing smaller and fainter galaxies. All of these are properties that we know have some relation with the galaxy environment. For example, there are more elliptical galaxies in denser environments than you can find in the field, which is mainly populated by spiral galaxies. This relation is known as the morphology-density relation.
Es bien conocido que el entorno donde viven las galaxias juega un papel importante en su formación y evolución. Las galaxias de la muestra de MaNGA muestran muchas formas diferentes. Hay galaxias que son elípticas, lenticulares y espirales, pero también hay galaxias peculiares como galaxias enanas y fusiones de galaxias o galaxias en interacción. También hay galaxias ...
