Description
The position of the Earth in the Milky Way galaxy allows detailed study of stellar and gas processes inside the Galaxy. On the other hand, Earth's position inside the Milky Way disk inhibits vision of the entirety of the Galaxy, complicating studies of the Galaxy in its entirety. One solution is to study stellar populations of other galaxies with similar properties to the Milky Way. These so-called Milky Way Analogues (MWAs) are likely to have a similar formation history to our own galaxy.
The search for MWA-s has been based mainly on the compatibility of the Milky Way's own properties, such as morphology, mass, and star formation rate. It is also reasonable to consider the structure of the Local Group, which is a trace of the formation history of the Milky Way's environment. Studying the MWA-s also gives us an idea of how unique our home galaxy is and whether this may be the reason why life has been able to arise and develop here.
The goal of this project is to improve the sample of MWA-s using data from the Javalambre Physics of the Accelerating Universe Astrophysical Survey (J-PAS). The unique 56 filter system of J-PAS covers the entire optical range with narrow band filters. J-PAS opens up an excellent opportunity to consider both the internal structure of MWA-s and their surroundings. Here I present a selection of the most Milky Way-like galaxies in the current J-PAS survey footprint and preliminary analysis of their internal structure.
