Magnetic fields play a role in the dynamics of many astrophysical processes, but they are hard to detect. In a partially ionized plasma, a magnetic field works directly on the ionized medium but not on the neutral medium, which gives rise…

The directed flow ($v_1$) of identified hadrons ($\pi^{\pm}, K^{\pm}, p, \bar{p}, \phi, \Lambda$, and $\bar{\Lambda}$) is studied in symmetric nuclear collisions (O+O, Cu+Cu, Ru+Ru, Au+Au, and U+U) at $\sqrt{s_{NN}} = 200$ GeV using the…
