Abstract:
We characterize the local (2kpc sized) environments of Type Ia, II,
and Ib/c supernovae (SNe) that have recently occurred in nearby
(d≲50Mpc) galaxies. Using ultraviolet (UV; from Galaxy Evolution
Explorer) and infrared (IR; from Wide-field Infrared Survey Explorer)
maps of 359 galaxies and a sample of 472 SNe, we measure the star
formation rate surface density (ΣSFR) and stellar mass surface
density (Σ*) in a 2kpc beam centered on each SN site. We show
that core-collapse SNe are preferentially located along the resolved
galactic star-forming main sequence, whereas Type Ia SNe are extended
to lower values of ΣSFR at fixed Σ*, indicative of
locations inside quiescent galaxies or quiescent regions of galaxies.
We also test how well the radial distribution of each SN type matches
the radial distributions of UV and IR light in each host galaxy. We
find that, to first order, the distributions of all types of SNe
mirror those of both near-IR light (3.4 and 4.5µm, tracing the
stellar mass distribution) and mid-IR light (12 and 22µm, tracing
emission from hot, small grains), and also resemble our best-estimate
ΣSFR. All types of SNe appear more radially concentrated than
the UV emission of their host galaxies. In more detail, the
distributions of Type II SNe show small statistical differences from
those of near-IR light. We attribute this overall structural
uniformity to the fact that within any individual galaxy, ΣSFR
and Σ* track one another well, with variations in
ΣSFR/Σ* most visible when comparing between galaxies.
Description:
We begin with an atlas of WISE IR and Galaxy Evolution Explorer
(GALEX) UV maps of ∼16000 local galaxies (Leroy+ 2019, J/ApJS/244/24).
For each galaxy in the atlas, we use the Open Supernova Catalog (OSC;
Guillochon+ 2017ApJ...835...64G 2017ApJ...835...64G) to identify SNe that have occurred in
that galaxy. Then, we measure the intensity of IR and UV emission at
the location of each SN. We compare these intensities with the
distribution of IR and UV intensity from the whole host galaxy.
