Measuring Dark Energy Properties with Photometrically Classified Pan-STARRS Supernovae. II. Cosmological Parameters
D. O. Jones, D. M. Scolnic, A. G. Riess +25
We use 1169 Pan-STARRS supernovae (SNe) and 195 low- () SNe Ia to measure cosmological parameters. Though most Pan-STARRS SNe lack spectroscopic classifications, in a p…
The Complete Light-curve Sample of Spectroscopically Confirmed Type Ia Supernovae from Pan-STARRS1 and Cosmological Constraints from The Combined Pantheon Sample
D. M. Scolnic, D. O. Jones, A. Rest +37
We present optical light curves, redshifts, and classifications for 365 spectroscopically confirmed Type Ia supernovae (SNe Ia) discovered by the Pan-STARRS1 (PS1) Medium Deep Surv…
An updated Type II supernova Hubble diagram
E. E. E. Gall, R. Kotak, B. Leibundgut +15
We present photometry and spectroscopy of nine Type II-P/L supernovae (SNe) with redshifts in the 0.045 < z < 0.335 range, with a view to re-examining their utility as distance ind…
On the nature of Hydrogen-rich Superluminous Supernovae
C. Inserra, S. J. Smartt, E. E. E. Gall +33
We present two hydrogen-rich superluminous supernovae (SLSNe), namely SN2013hx and PS15br. These objects, together with SN2008es are the only SLSNe showing a distinct, broad Halpha…
