Noel Gallagher announced that he quitted Oasis on 28 August, 2009. He said that he could not work with his brother, Liam any longer because they often made a quarrel each other. Finally, Noel could not be patient so that he quitted the band. All of Oasis's songs were made by Noel, so Oasis disbanded officially in 2009.
After quitting Oasis, Noel started solo project "Noel Gallagher's High flying Birds".
While, young brother, Liam started the new band "Beady Eye" with the member of Oasis without his old brother, Noel.
A lot of Oasis's fans and I are hope that Noel and Liam get friendly and come back to play together again as Oasis!!! :)
