Ultimate DM detector
We disclose an implementation of RT-bolometers which comprise high chemical-energy materials, e.g. explosive or catalase, H2O2}-system, that can be operated at temperature between 4 oC and room temperature (RT). Energy deposited by the incident weakly interacting particle to the nuclei can trigger a local release of chemical energy;. The energy release in such a `nano-explosion’ indicates that a coherent scattering event has taken place and allows for the localization of this event;

Title: First Tau Neutrino airshower astronomy ( and Signals?)
Abstract: PeV-EeV energy neutrino Tau may lead to a filtered and amplified upward tau Airshower Astronomy. Present and future experiment may ( already or soon) disentangle tau neutrino astronomy signals: ANITA, Grand, Poemma, Auger and other group are in rush for this peculiar neutrino horizons.

"The early growth of supermassive black holes": Supermassive black holes with masses of several billion solar masses are already in place at z~6-7. I will discuss models and numerical simulations of the early growth of these supermassive black holes and their environment with an emphasis - on the role of the formation of massive seed black holes by direct collapse in DM haloes with virial temperatures above the atomic cooling threshold, - and the role of AGN feedback in driving outflows and regulating the growth of supermassive black holes.
