Summary: We establish here the surjectivity of the Albanese map corresponding to compact Kähler manifold whose anti-canonical bundle is nef. This answers a question raised by J.-P. Demailly et al. [J. Algebr. Geom. 3, No. 2, 295–345 (1994; Zbl 0827.14027)]. One of the main techniques we are using is the positivity of the relative canonical bundle associated to Kähler fiber spaces, obtained via the “psh variation” of fiber-wise twisted Kähler-Einstein metrics.
