The bright galaxies comes in different colours and show different activities. Some are red, some blue and others have angry supermassive blackholes. These galaxies acts as the doorway to the cosmological universe we live in. Our understanding of inner working of universe and its mysterious dark components of matter and energy depends on the very large scale structure formed by these bright galaxies. The vibrant colours and behaviour shown in these galaxies hints towards rich physics involved in how they come about, live and die. I will discuss how we can learn some of the galaxy physics using measurements from galaxy redshift survey and at the same time how such understanding can play a crucial role in cosmological measurements. I will show examples from current available data and emphasis the importance for upcoming and future surveys.
