Extending an infinite simple group
I think this is sufficient to answer my question. |

Extending an infinite simple group
If this argument works, then by a Skolemization including $H$, it holds for any cardinal $\kappa\geq|H|$. |

Woodin on Posner-Robinson for the hyperjump and sharp
Ted may have a proof for Turing degrees for the HYP version by Kumabe-Slaman forcing. |

Non null Turing antichain
@Ashutosh I think it is true by Csima, Downey, Greenberg, Hirschfeldt, and Miller's result in the paper " Every 1-generic computes a properly 1-generic, The Journal of Symbolic Logic, 71:1385–1393, 2006." |

It was closed by CT and me. But the proof is pretty involved (We used a lot of results from higher randomness). |

You are right. It fails under $CH$. Actually we need $MA_{\aleph_1}$ to prove it. |

Hmm... I remember I gave a talk about these facts in Madison. Maybe you were not there. But I am sure that Mushfeq was there. |
