STag: Supernova Tagging and Classification
William Davison, David Parkinson, Brad E. Tucker
Supernovae classes have been defined phenomenologically, based on spectral features and time series data, since the specific details of the physics of the different explosions rema…
Photometric and spectroscopic evolution of the interacting transient AT 2016jbu (Gaia16cfr)
S. J. Brennan, M. Fraser, J. Johansson +68
We present the results from a high cadence, multi-wavelength observation campaign of AT 2016jbu (aka Gaia16cfr), an interacting transient. This dataset complements the current lite…
Photometric and Spectroscopic Properties of Type Ia Supernova 2018oh with Early Excess Emission from the 2 Observations
W. Li, X. Wang, J. Vinkó +160
Supernova (SN) 2018oh (ASASSN-18bt) is the first spectroscopically-confirmed type Ia supernova (SN Ia) observed in the field. The data revealed an excess emission…
New Parallaxes of Galactic Cepheids from Spatially Scanning the Hubble Space Telescope: Implications for the Hubble Constant
Adam G. Riess, Stefano Casertano, Wenlong Yuan +8
We present new parallax measurements of 7 long-period (> 10 days) Milky Way Cepheids (SS CMa, XY Car, VY Car, VX Per, WZ Sgr, X Pup and S Vul) using astrometry from spatial scannin…
Optical Identification of Cepheids in 19 Host Galaxies of Type Ia Supernovae and NGC 4258 with the Hubble Space Telescope
Samantha L. Hoffmann, Lucas M. Macri, Adam G. Riess +10
We present results of an optical search for Cepheid variable stars using the Hubble Space Telescope (HST) in 19 hosts of Type Ia supernovae (SNe Ia) and the maser-host galaxy NGC 4…
450 Days of Type II SN 2013ej in Optical and Near-Infrared
Fang Yuan, A. Jerkstrand, S. Valenti +31
We present optical and near-infrared photometric and spectroscopic observations of SN 2013ej, in galaxy M74, from 1 to 450 days after the explosion. SN 2013ej is a hydrogen-rich su…
