Characterizing the Fast Radio Burst Host Galaxy Population and its Connection to Transients in the Local and Extragalactic Universe

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