Abstract:
Spectra of broad-lined Type Ic supernovae (SNe Ic-BL), the only kind
of SN observed at the locations of long-duration gamma-ray bursts
(LGRBs), exhibit wide features indicative of high ejecta velocities
(∼0.1c). We study the host galaxies of a sample of 245 low-redshift
(z < 0.2) core-collapse SNe, including 17 SNe Ic-BL, discovered by
galaxy-untargeted searches, and 15 optically luminous and
dust-obscured z < 1.2 LGRBs. We show that, in comparison with Sloan
Digital Sky Survey galaxies having similar stellar masses, the hosts
of low-redshift SNe Ic-BL and z < 1.2 LGRBs have high stellar mass and
star formation rate densities. Core-collapse SNe having typical ejecta
velocities, in contrast, show no preference for such galaxies.
Moreover, we find that the hosts of SNe Ic-BL, unlike those of SNe
Ib/Ic and SNe II, exhibit high gas velocity dispersions for their
stellar masses. The patterns likely reflect variations among
star-forming environments and suggest that LGRBs can be used as probes
of conditions in high-redshift galaxies. They may be caused by
efficient formation of massive binary progenitor systems in densely
star-forming regions, or, less probably, a higher fraction of stars
created with the initial masses required for an SN Ic-BL or LGRB.
Finally, we show that the preference of SNe Ic-BL and LGRBs for
galaxies with high stellar mass and star formation rate densities
cannot be attributed to a preference for low metal abundances but must
reflect the influence of a separate environmental factor.
Description:
We study the host galaxies of both nearby (z<0.2) core-collapse SNe
discovered by "galaxy-untargeted" transient searches (e.g., the
Palomar Transient Factory (PTF); Rau et al., 2009PASP..121.1334R 2009PASP..121.1334R; Law
et al., 2009PASP..121.1395L 2009PASP..121.1395L), which do not target specific potential
hosts or z<1.2 LGRBs detected by gamma-ray satellites. We use the SDSS
spectroscopic sample to build a control sample of low-redshift
star-forming galaxies and SDSS photometry and spectroscopy to measure
properties of both the sample of low-redshift star-forming galaxies
and the host galaxies of the nearby SNe. For the host galaxies of
z<1.2 LGRBs, we estimate host properties using published photometry
and HST imaging.
