Observational Constraints On The Interaction Between Dark Matter And Dark Energy

In this work we use the latest observations on BAO, SNIa, and H(z), to constraint three models, two of them showing an explicit interaction between dark matter and dark energy. We found that using the three observational probes together, one of the interaction model (the IwCDM2) shows evidence for interaction at 2 σ. Although significant, further study is necessary to establish this claim firmly.
