The Pantheon+ Analysis: Cosmological Constraints
Dillon Brout, Dan Scolnic, Brodie Popovic +43
We present constraints on cosmological parameters from the Pantheon+ analysis of 1701 light curves of 1550 distinct Type Ia supernovae (SNe Ia) ranging in redshift from t…
Cosmological Results from the RAISIN Survey: Using Type Ia Supernovae in the Near Infrared as a Novel Path to Measure the Dark Energy Equation of State
D. O. Jones, K. S. Mandel, R. P. Kirshner +26
Type Ia supernovae (SNe Ia) are more precise standardizable candles when measured in the near-infrared (NIR) than in the optical. With this motivation, from 2012-2017 we embarked o…
The morphology of the ejecta of SN 1987A at 31 years from 1150 to 10000 Å
Tuomas Kangas, Claes Fransson, Josefin Larsson +7
We present spectroscopy of the ejecta of SN 1987A in 2017 and 2018 from the Hubble Space Telescope and the Very Large Telescope, covering the wavelength range between and $1…
The Pantheon+ Analysis: The Full Dataset and Light-Curve Release
Dan Scolnic, Dillon Brout, Anthony Carr +27
Here we present 1701 light curves of 1550 spectroscopically confirmed Type Ia supernovae (SNe Ia) that will be used to infer cosmological parameters as part of the Pantheon+ SN ana…
Carnegie Supernova Project-II: Near-infrared Spectroscopy of Stripped-Envelope Core-Collapse Supernovae
M. Shahbandeh, E. Y. Hsiao, C. Ashall +29
We present 75 near-infrared (NIR; 0.82.5 m) spectra of 34 stripped-envelope core-collapse supernovae (SESNe) obtained by the Carnegie Supernova Project-II (CSP-II), encompass…
ASASSN-15hy: an under-luminous, red 03fg-like type Ia supernova
J. Lu, C. Ashall, E. Y. Hsiao +33
We present photometric and spectroscopic observations of the 03fg-like type Ia supernova (SN Ia) ASASSN-15hy from the ultraviolet (UV) to the near-infrared (NIR). ASASSN-15hy share…
