Despite the scientific impact of their discovery, both León and Vega agreed to end their research and allow other academics to take over. After five years working on the project, they are ready to let it go and allow other experts continue the research. this seems bizarre to me. it cannot be a matter of funding. they've spent 5 years gathering a great deal of expertise, and now decide to quit just when momentum has built up? they could instead seek collaborations on future work, if they want other people to work on this direction. otherwise there is likely a lot of catching up to do that is perhaps intimidating.
