Abstract:
We present observations of three core-collapse supernovae (CCSNe) in
elliptical hosts, detected by the Zwicky Transient Facility Bright
Transient Survey (BTS). SN 2019ape is a SN Ic that exploded in the
main body of a typical elliptical galaxy. Its properties are
consistent with an explosion of a regular SN Ic progenitor. A
secondary g-band light-curve peak could indicate interaction of the
ejecta with circumstellar material (CSM). An Hα-emitting source
at the explosion site suggests a residual local star formation origin.
SN 2018fsh and SN 2020uik are SNe II which exploded in the outskirts
of elliptical galaxies. SN 2020uik shows typical spectra for SNe II,
while SN 2018fsh shows a boxy nebular Hα profile, a signature of
CSM interaction. We combine these 3 SNe with 7 events from the
literature and analyze their hosts as a sample. We present
multi-wavelength photometry of the hosts, and compare this to archival
photometry of all BTS hosts. Using the spectroscopically complete BTS,
we conclude that 0.3%-0.1+0.3 of all CCSNe occur in elliptical
galaxies. We derive star formation rates and stellar masses for the
host galaxies and compare them to the properties of other SN hosts. We
show that CCSNe in ellipticals have larger physical separations from
their hosts compared to SNe Ia in elliptical galaxies, and discuss
implications for star-forming activity in elliptical galaxies.
Description:
The ZTF Bright Transient Survey (BTS; Fremling+ 2020, J/ApJ/895/32 ;
Perley+ 2020ApJ...904...35P 2020ApJ...904...35P) is the largest untargeted
spectroscopically complete SN survey to date. For all SNe discussed in
this paper, we acquired gri photometry using the P48 ZTF camera.
Additional photometry was acquired with the Las Cumbres Observatory
(LCO) network of 1m telescopes through the Global Supernova Project
(Howell 2019AAS...23325816H 2019AAS...23325816H); the two ATLAS 0.5m telescopes on
Haleakala and Mauna Loa, Hawaii, USA; the 2.0m robotic Liverpool
Telescope (LT) at the Observatorio del Roque de los Muchachos
Observatory on La Palma using the optical imager (IO:O) through the g,
r, i, and z bands; the Rainbow Camera on the Palomar 60 inch telescope
(P60).
Spectroscopic follow-up of SNe appearing in this work was performed
using a variety of instruments. See Section 3.2.
