| Abstract : | Dark matter haloes provide gravitational potential to form galaxies, and hence the galaxy properties significantly depend on the properties of haloes and hence the local environment in which these galaxies live. Quantifying these environmental correlations of various galaxy properties are crucial for the better understanding of galaxy formation and evolution. One of the methods to study these correlations is measurement of galaxy clustering and its dependence on galaxy properties. In this presentation, I will show the results from our recent investigations on how galaxy properties like stellar mass, luminosities in the u, g, r, J, and K bands correlate with the environment. We measure galaxy two-point correlation function and marked correlation function by weighting the galaxies using the aforementioned properties. We use galaxy samples from the least explored (southern) regions of the Galaxy and Mass Assembly (GAMA) survey. Furthermore, we explore how survey completeness affects the measurements by comparing them between different subsets of the survey region with varying spatial completeness. |
