dc.description.abstract	In this work we show that modifying the thermal history of the Universe by including an early period of matter domination can lead to the formation of astronomical objects. However, the survival of these objects can only be possible if the dominating matter decays to a daughter particle which is not only almost degenerate with the parent particle but also has an open coannihilation channel. This requirement translates in an upper bound for the coupling of such a channel and makes the early structure formation viable.
