The blazar TXS 0506+056 is a candidate of high-energy neutrino sources. We propose that its neutrino emission could originate from the core region rather than the jet. We suggests that high-energy protons, accelerated by magnetic reconnection within a magnetically arrested disk (MAD) near the central black hole, interact with photons from the accretion disk and corona to produce neutrinos.

The memory burden effect, which stabilizes systems by storing information, plays a key role in black holes, where evaporation halts after roughly half the initial mass is lost. This suggests that light primordial black holes (PBHs) with mass below 10^15 g, expected to have fully evaporated, may still be viable dark matter (DM) candidates. We show that their mergers could form "young" black...
