Abstract:
Using ultraviolet (UV) light curves, we constrain the circumstellar
environments of 1080 Type Ia supernovae (SNe Ia) within z<0.5 from
archival Galaxy Evolution Explorer (GALEX) observations. All SNe Ia
are required to have pre- and post-explosion GALEX observations to
ensure adequate subtraction of the host-galaxy flux. Using the
late-time GALEX observations, we look for the UV excess expected from
any interaction between the SN ejecta and circumstellar material
(CSM). Four SNe Ia are detected near maximum light, and we compare the
GALEX photometry to archival data. However, we find that none of our
targets show convincing evidence of CSM interaction. A recent Hubble
Space Telescope (HST) survey estimates that ∼6% of SNe Ia may interact
with distant CSM, but statistical inferences are complicated by the
small sample size and selection effects. By injecting model light
curves into our data and then recovering them, we constrain a broad
range of CSM interactions based on the CSM interaction start time and
the maximum luminosity. Combining our GALEX nondetections with the HST
results, we constrain occurrence of late-onset CSM interaction among
SNe Ia with moderate CSM interaction, similar to that observed in
PTF11kx, to fCSM≲5.1% between 0 and 500 days after discovery and
≲2.7% between 500 and 1000 days after discovery at 90% confidence.
For weaker CSM interactions similar to SN 2015cp, we obtain limits of
≲16% and ≲4.8%, respectively, for the same time ranges.
Description:
We obtained GALEX UV light curves of 1080 SNe Ia to search for
signatures of SN Ia ejecta interacting with nearby circumstellar
material. GALEX was a NASA Small Explorer telescope that surveyed the
entire sky in the UV (FUV, 1340-1800Å and NUV, 1700-3000Å bands)
from 2003 to 2013, and its data are publicly available at the Mikulski
Archive for Space Telescopes (MAST).
