Characterizing the FRB host galaxy population and its connection to
  transients in the local and extragalactic Universe
  We present the localization and host galaxies of one repeating and two
apparently non-repeating Fast Radio Bursts. FRB20180301A was detected and
localized with the Karl G. Jansky Very Large Array to a star-forming galaxy at
$z=0.3304$. FRB20191228A, and FRB20200906A were detected and localized by the
Australian Square Kilometre Array Pathfinder to host galaxies at $z=0.2430$ and
$z=0.3688$, respectively. We combine these with 13 other well-localized FRBs in
the literature, and analyze the host galaxy properties. We find no significant
differences in the host properties of repeating and apparently non-repeating
FRBs. FRB hosts are moderately star-forming, with masses slightly offset from
the star-forming main-sequence. Star formation and low-ionization nuclear
emission-line region (LINER) emission are major sources of ionization in FRB
host galaxies, with the former dominant in repeating FRB hosts. FRB hosts do
not track stellar mass and star formation as seen in field galaxies (more than
95% confidence). FRBs are rare in massive red galaxies, suggesting that
progenitor formation channels are not solely dominated by delayed channels
which lag star formation by Gigayears. The global properties of FRB hosts are
indistinguishable from core-collapse supernovae (CCSNe) and short gamma-ray
bursts (SGRBs) hosts, and the spatial offset (from galaxy centers) of FRBs is
mostly inconsistent with that of the Galactic neutron star population (95%
confidence). The spatial offsets of FRBs (normalized to the galaxy effective
radius) also differ from those of globular clusters (GCs) in late- and
early-type galaxies with 95% confidence.
