Analysis of the Internal Radial Gradient of Chemical Abundances in Spiral Galaxies from CALIFA

open access: yesThe Astrophysical Journal
The study of chemical evolution is of paramount importance for understanding the evolution of galaxies. Models and observations propose an inside-out mechanism in the formation of spiral galaxy disks, implying a negative radial gradient of elemental ...

Living with Neighbors. V. Better-aligned Spiral+Spiral Galaxy Pairs Show Stronger Star Formation

open access: yesThe Astrophysical Journal
Enhanced star formation (SF) with star-forming neighboring galaxies bolsters the hydrodynamical contributions during paired interactions. Although the relative spin orientation between interacting galaxies can influence this effect, it has not been ...

Mapping the Active Galactic Nucleus Effects on the Stellar and Gas Properties of NGC 5806

open access: yesThe Astrophysical Journal
It is commonly accepted that active galactic nuclei (AGNs) have a strong impact upon the evolution of their host galaxies, but the processes by which they do so are not fully understood.
