Query: Spatially Resolved Studies of Local Massive Red Spiral Galaxies   We report two-dimensional spectroscopic analysis of massive red spiral
galaxies ($M_{*}$ $>$ 10$^{10.5}$ $M_{\odot}$) and compare them to blue spiral
and red elliptical galaxies above the same mass limit based on the public SDSS
DR15 MaNGA observations. We find that the stellar population properties of red
spiral galaxies are more similar to those of elliptical galaxies than to blue
spiral galaxies. Red spiral galaxies show a shallow mass-weighted age profile,
and they have higher stellar metallicity and Mgb/${\rm \langle Fe \rangle}$
across the whole 1.5$R_{\rm e}$ as compared to blue spirals, but all these
properties are close to those of elliptical galaxies. One scenario to explain
this is that red spirals form as remnants of very gas-rich major mergers that
happened above $z$$\sim$1.
