The correlation between the luminosity of active galactic nuclei and host galaxy parameters

Abstract

I explore the correlation between the X-ray luminosity of the 13 galaxies selected and values
such as the galaxies' inferred stellar mass and its color. The galaxies selected, in the
0. 024710 ≤ 𝑧 ≤ 0. 095000 range, are all containing an active galactic nucleus, for which I
determine the luminosity by using the X-ray luminosity as a proxy. I then plot it against the
inferred stellar mass and color of each galaxy. The results show a negative correlation for the
X-ray luminosity vs Inferred Stellar Mass plot, and a slight positive for the X-ray luminosity vs
Color plot, indicating a connection between the luminosity of an active galactic nucleus and its
ability to quench star formation, hence reducing stellar mass and increasing the age of the
average of the stars, increasing the color value.
