SN 2019muj -- a well-observed Type Iax supernova that bridges the luminosity gap of the class
Barnabás Barna, Tamás Szalai, Saurabh W. Jha +38
We present early-time ( days) observations of SN 2019muj (= ASASSN-19tr), one of the best-observed members of the peculiar SN Iax class. Ultraviolet and optical photometri…
The electron-capture origin of supernova 2018zd
Daichi Hiramatsu, D. Andrew Howell, Schuyler D. Van Dyk +27
In the transitional mass range ( 8-10 solar masses) between white dwarf formation and iron core-collapse supernovae, stars are expected to produce an electron-capture superno…
Supernova 2018cuf: A Type IIP supernova with a slow fall from plateau
Yize Dong, S. Valenti, K. A. Bostroem +34
We present multi-band photometry and spectroscopy of SN 2018cuf, a Type IIP ("P" for plateau) supernova (SN) discovered by the Distance Less Than 40 Mpc survey (DLT40) within 24 ho…
Luminous Type II Short-Plateau Supernovae 2006Y, 2006ai, and 2016egz: A Transitional Class from Stripped Massive Red Supergiants
Daichi Hiramatsu, D. Andrew Howell, Takashi J. Moriya +21
The diversity of Type II supernovae (SNe II) is thought to be driven mainly by differences in their progenitor's hydrogen-rich (H-rich) envelope mass, with SNe IIP having long plat…
Near-Infrared and Optical Observations of Type Ic SN2020oi and broad-lined Ic SN2020bvc: Carbon Monoxide, Dust and High-Velocity Supernova Ejecta
J. Rho, A. Evans, T. R. Geballe +33
We present near-infrared and optical observations of the Type Ic Supernova (SN) 2020oi in the galaxy M100 and the broad-lined Type Ic SN2020bvc in UGC 9379, using Gemini, LCO, SOAR…
The Exotic Type Ic Broad-Lined Supernova SN 2018gep: Blurring the Line Between Supernovae and Fast Optical Transients
T. A. Pritchard, Katarzyna Bensch, Maryam Modjaz +28
In the last decade a number of rapidly evolving transients have been discovered that are not easily explained by traditional supernovae models. We present optical and UV data on on…
A new measurement of the Hubble constant using Type Ia supernovae calibrated with surface brightness fluctuations
N. Khetan, L. Izzo, M. Branchesi +15
We present a new calibration of the peak absolute magnitude of SNe Type Ia based on the Surface Brightness Fluctuations (SBF) method, aimed at measuring the value of the Hubble con…
SN 2019ehk: A Double-Peaked Ca-rich Transient with Luminous X-ray Emission and Shock-Ionized Spectral Features
Wynn V. Jacobson-Galán, Raffaella Margutti, Charles D. Kilpatrick +64
We present panchromatic observations and modeling of the Calcium-rich supernova 2019ehk in the star-forming galaxy M100 (d16.2 Mpc) starting 10 hours after explosion and c…
The low-luminosity type II SN\,2016aqf: A well-monitored spectral evolution of the Ni/Fe abundance ratio
Tomás E. Müller-Bravo, Claudia P. Gutiérrez, Mark Sullivan +20
Low-luminosity type II supernovae (LL SNe~II) make up the low explosion energy end of core-collapse SNe, but their study and physical understanding remain limited. We present SN\,2…
