  • In relativistic heavy-ion collisions, the extractions of properties of quark-gluon plasma (QGP) are hindered by a limited understanding of its initial conditions, where the nuclear structure of the colliding ions play a significant role. In these proceedings, we present the first quantitative demonstration using ``collective flow assisted nuclear shape imaging" method to extract the quadrupole deformation and triaxiality from $^{238}$U using data from the Relativistic Heavy Ion Collider (RHIC). We achieve this by comparing bulk observables in $^{238}$U+$^{238}$U collisions with nearly spherical $^{197}$Au+$^{197}$Au collisions. A similar comparative measurement performed in collisions of $^{96}$Ru+$^{96}$Ru and $^{96}$Zr+$^{96}$Zr, suggests the presence of moderate quadrupole deformation of $^{96}$Ru, large octupole deformation of $^{96}$Zr, as well as an apparent neutron skin difference between these two species. The prospect of this nuclear shape imaging method as a novel tool for the study of nuclear structure is also elaborated.
