Abstract:
We analyse the 476 SN Ia host galaxies from the All-Sky Automated
Survey for Supernova (ASAS-SN) Bright Supernova Catalogues to
determine the observed relative Type Ia supernova (SN) rates as a
function of luminosity and host galaxy properties. We find that the
luminosity distribution of the SNe Ia in our sample is reasonably well
described by a Schechter function with a faint-end slope α∼1.5
and a knee M*~-18.0. Our specific SN Ia rates are consistent with
previous results but extend to far lower host galaxy masses. We find
an overall rate that scales as (M*/1010M☉)α with
α~-0.5. This shows that the specific SN Ia rate continues rising
towards lower masses even in galaxies as small as
log(M*/M☉)~<7.0, where it is enhanced by a factor of ∼10-20
relative to host galaxies with stellar masses ∼1010M☉. We find
no strong dependence of the specific SN Ia rate on the star formation
activity of the host galaxies, but additional observations are
required to improve the constraints on the star formation rates.
Description:
The SN Ia sample is constructed from the ASAS-SN Bright Supernova
Catalogues (Holoien et al. 2017MNRAS.464.2672H 2017MNRAS.464.2672H, Cat. J/MNRAS/464/2672,
2017MNRAS.467.1098H 2017MNRAS.467.1098H, Cat. J/MNRAS/467/1098, 2017MNRAS.471.4966H 2017MNRAS.471.4966H,
J/MNRAS/471/4966). These catalogues contain 476 SNe Ia in total.
ASAS-SN discovered 325 of these SNe Ia, and out of the 151 not
discovered by ASAS-SN, 84 were recovered in ASAS-SN data. Also, the
ASAS-SN Bright Supernova Catalogues contain archival data from the
Galaxy Evolution Explorer (GALEX; Morrissey et al.
2007ApJS..173..682M 2007ApJS..173..682M) All Sky Imaging Survey, the optical ugriz model
magnitudes from the Sloan Digital Sky Survey Data Release 13 (SDSS
DR13; Albareti et al. 2017ApJS..233...25A 2017ApJS..233...25A), the near-infrared (NIR)
JHKS magnitudes from the Two-Micron All Sky Survey (2MASS; Skrutskie
et al. 2006AJ....131.1163S 2006AJ....131.1163S, Cat. VII/233), and the IR W1 and W2
magnitudes from the Wide-field Infrared Survey Explorer (WISE; Wright
et al. 2010AJ....140.1868W 2010AJ....140.1868W) AllWISE source catalogue.
To supplement the optical coverage of host galaxies in our sample, we
also retrieve the grizy data from the Panoramic Survey Telescope and
Rapid Response System (Pan-STARRS; Chambers et al.
2016arXiv161205560C 2016arXiv161205560C, Cat. II/349).
The auxiliary data for the SNe and host galaxies used in this analysis
are presented in Table A1 and the photometry of the host galaxies is
presented in Table A2.
