Minutes-duration Optical Flares with Supernova Luminosities
Anna Y. Q. Ho, Daniel A. Perley, Ping Chen +74
In recent years, certain luminous extragalactic optical transients have been observed to last only a few days. Their short observed duration implies a different powering mechanism…
Strong Carbon Features and a Red Early Color in the Underluminous Type Ia SN 2022xkq
Jeniveve Pearson, David J. Sand, Peter Lundqvist +85
We present optical, infrared, ultraviolet, and radio observations of SN 2022xkq, an underluminous fast-declining type Ia supernova (SN Ia) in NGC 1784 ( Mpc),…
Newly Formed Dust within the Circumstellar Environment of SNIa-CSM 2018evt
Lingzhi Wang, Maokai Hu, Lifan Wang +44
Dust associated with various stellar sources in galaxies at all cosmic epochs remains a controversial topic, particularly whether supernovae (SNe) play an important role in dust pr…
Long-term follow-up observations of extreme coronal line emitting galaxies
Peter Clark, Or Graur, Joseph Callow +40
We present new spectroscopic and photometric follow-up observations of the known sample of extreme coronal line emitting galaxies (ECLEs) identified in the Sloan Digital Sky Survey…
A Precursor Plateau and Pre-Maximum [O II] Emission in the Superluminous SN2019szu: A Pulsational Pair-Instability Candidate
Aysha Aamer, Matt Nicholl, Anders Jerkstrand +29
We present a detailed study on SN2019szu, a Type I superluminous supernova at , that displayed unique photometric and spectroscopic properties. Pan-STARRS and ZTF forced p…
Roman CCS White Paper: Identifying high-redshift pair-instability supernovae by adding sparse F213 filter observations
Takashi Moriya, Ori D. Fox, Robert Quimby +22
Pair-instability supernovae (PISNe) are explosions of very massive stars that may have played a critical role in the chemical evolution and reionization of the early Universe. In o…
