Query: Self-gravity in neutrino-dominated accretion disks   We present the effects of the self-gravity on the vertical structure and
neutrino luminosity of the neutrino-dominated accretion disks in cylindrical
coordinates. It is found that significant changes of the structure appear in
the outer region of the disk, especially for high accretion rates (e.g., $\ga 1
M_\odot~\rm s^{-1}$), and thus causes the slight increase of the neutrino
luminosity. Furthermore, the gravitational instability of the disk is reviewed
by the vertical distribution of the Toomre parameter \citep{Toomre1964}, which
may account for the late-time flares in gamma-ray bursts and the extended
emission in short-duration gamma-ray bursts.
