Understanding neutrino physics in black hole accretion disks: 

Understanding neutrino physics in black hole accretion disks Neutrino and antineutrino decoupling surfaces for black hole accretion disks with accretion rates of (a) 10 and (b) 1 solar mass(es) per second (H is the scale height of the disk; neutrinos are trapped within the dashed regions) Surman & McLaughlin, ApJ, 603, 611 (2004) (a) (b)

Future opportunities: Influence of neutrinos on nucleosynthesis in outflows from black hole accretion disks: 

Future opportunities: Influence of neutrinos on nucleosynthesis in outflows from black hole accretion disks Calculations of nucleosynthesis using a parameterized wind model suggest that outflows from black hole accretion disks may contribute to the galactic abundances of some rare nuclear species, such as light proton-rich nuclei or r process nuclei. Careful calculations of the neutrino fluxes from the accretion disk are essential to accurately determine this nucleosynthesis.
