Proxies for stellar mass and star formation rate from galaxy clustering

Unnikrishnan Sureshkumar, Anna Durkalec and Agnieszka Pollo

We study the environmental dependence of galaxy properties at the redshift range 0.07≤z<0.15 using galaxies from Galaxy and Mass Assembly (GAMA) survey and making use of their mid infrared WISE observations. We measure marked correlation functions for a W1 (3.4 µm) absolute magnitude selected sample using luminosities in u, K, W1, W2, W3, W4 bands, stellar mass and star formation rate as marks. We then compare their amplitude to see which photometric bands are better proxies for stellar mass and SFR in the context of galaxy clustering.
