Galactic habitability re-examined: indications of bimodality

摘要: The problem of the extent habitable zones in different kinds galaxies is one outstanding challenges for contemporary astrobiology. In present study, we investigate habitability a large sample simulated from Illustris Project order to at least roughly quantify hospitality life galactic types. pioneering study Dayal et al. (2015) critically examined and some its results are amended. particular, find tentative evidence second mode comprising metal-rich dwarfs similar IC 225, LMC or M32. role environment observation selection effects briefly discussed prospects further research on topic outlined.
