Abstract:
We present optical and near-infrared (NIR, Y-, J-, H-band)
observations of 42 Type Ia supernovae (SNe Ia) discovered by the
untargeted intermediate Palomar Transient Factory survey. This new
data set covers a broad range of redshifts and host galaxy stellar
masses, compared to previous SN Ia efforts in the NIR. We construct a
sample, using also literature data at optical and NIR wavelengths, to
examine claimed correlations between the host stellar masses and the
Hubble diagram residuals. The SN magnitudes are corrected for host
galaxy extinction using either a global total-to-selective extinction
ratio, RV=2.0, for all SNe, or a best-fit RV for each SN individually.
Unlike previous studies that were based on a narrower range in host
stellar mass, we do not find evidence for a "mass step," between the
color- and stretch- corrected peak J and H magnitudes for galaxies
below and above log(M*/M☉)=10. However, the mass step remains
significant (3σ) at optical wavelengths (g, r, i) when using a
global RV, but vanishes when each SN is corrected using their
individual best-fit RV. Our study confirms the benefits of the NIR SN
Ia distance estimates, as these are largely exempted from the
empirical corrections dominating the systematic uncertainties in the
optical.
Description:
During the intermediate Palomar Transient Factory (iPTF) survey, the
Palomar 48 inch (P48) telescope typically delivered g- and R-band
images.
Optical follow-up observations were collected using the Palomar 60inch
telescope (P60, BVgriz filters), the 2.56m Nordic Optical Telescope
(NOT), and the Las Cumbres Observatory (LCO) in UBVRI and/or
griz-bands.
For 37 out of 42 SNe in our sample, we acquired follow-up observations
using the Reionization and Transients InfraRed camera (RATIR). RATIR
is a six-band simultaneous optical and NIR imager (riZYJH bands)
mounted on the autonomous 1.5m Harold L. Johnson Telescope at the
Observatorio Astronomico Nacional on Sierra San Pedro Martir in Baja
California, Mexico.
For seven SNe Ia in our sample, J- and H-band observations were also
obtained using other facilities, such as HAWK-I on the 8m Very Large
Telescope (VLT; for iPTF14bbr, 14ddi, 14deb, 14eje, and 14fww), VIRCAM
on the 4m VISTA telescope (iPTF14fpb), and WIRC on the Palomar 200inch
telescope (iPTF14gnl).
