The interacting nature of dwarf galaxies hosting superluminous supernovae
The interacting nature of dwarf galaxies hosting superluminous supernovae
(Abridged) Type I superluminous supernovae (SLSNe I) are rare, powerful explosions whose mechanism and progenitors remain elusive. SLSNe I show a preference for low-metallicity, actively star-forming dwarf galaxies. We investigate whether the hosts of SLSNe I show increased evidence for interaction. We use a sample of 42 SLSN I images …
