Searches after Gravitational Waves Using ARizona Observatories (SAGUARO): Observations and Analysis from Advanced LIGO/Virgo's Third Observing Run
K. Paterson, M. J. Lundquist, J. C. Rastinejad +34
With the conclusion of the third observing run for Advanced LIGO/Virgo (O3), we present a detailed analysis of both triggered and serendipitous observations of 17 gravitational wav…
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…
High-resolution spectroscopy of SN 2017hcc and its blueshifted line profiles from post-shock dust formation
Nathan Smith, Jennifer E. Andrews
SN2017hcc was remarkable for being a nearby and strongly polarized superluminous TypeIIn supernova (SN). We obtained high-resolution echelle spectra that we combine with other spec…
The Blue Supergiant Progenitor of the Supernova Imposter AT~2019krl
Jennifer E. Andrews, Jacob E. Jencson, Schuyler D. Van Dyk +20
Extensive archival \textit{Hubble Space Telescope}, \textit{Spitzer Space Telescope}, and Large Binocular Telescope imaging of the recent intermediate-luminosity transient, AT~2019…
The Slow Demise of the Long-Lived SN 2005ip
Ori D. Fox, Claes Fransson, Nathan Smith +16
The Type IIn supernova (SN) 2005ip is one of the most well-studied and long-lasting examples of a SN interacting with its circumstellar environment. The optical light curve plateau…
SN 2014ab: An Aspherical Type IIn Supernova with Low Polarization
Christopher Bilinski, Nathan Smith, G. Grant Williams +20
We present photometry, spectra, and spectropolarimetry of supernova (SN) 2014ab, obtained through days after peak brightness. SN 2014ab was a luminous Type IIn SN ($M_V…
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…
Disentangling Dust Components in SN 2010jl: The First 1400 Days
A. M. Bevan, K. Krafton, R. Wesson +6
The luminous Type IIn SN 2010jl shows strong signs of interaction between the SN ejecta and dense circumstellar material. Dust may be present in the unshocked ejecta, the cool, den…
Constraining the Source of the High-velocity Ejecta in Type Ia SN 2019ein
C. Pellegrino, D. A. Howell, S. K. Sarbadhicary +16
We present multiwavelength photometric and spectroscopic observations of SN 2019ein, a high-velocity Type Ia supernova (SN Ia) discovered in the nearby galaxy NGC 5353 with a two-d…
A new and unusual LBV-like outburst from a Wolf-Rayet star in the outskirts of M33
Nathan Smith, Jennifer E. Andrews, Maxwell Moe +8
MCA-1B (also called UIT003) is a luminous hot star in the western outskirts of M33, classified over 20yr ago with a spectral type of Ofpe/WN9 and identified then as a candidate lum…
