Deep Drilling in the Time Domain with DECam: Survey Characterization
Melissa L. Graham, Robert A. Knop, Thomas Kennedy +41
This paper presents a new optical imaging survey of four deep drilling fields (DDFs), two Galactic and two extragalactic, with the Dark Energy Camera (DECam) on the 4 meter Blanco…
Flight of the Bumblebee: the Early Excess Flux of Type Ia Supernova 2023bee revealed by , and Young Supernova Experiment Observations
Qinan Wang, Armin Rest, Georgios Dimitriadis +41
We present high-cadence ultraviolet through near-infrared observations of the Type Ia supernova (SN Ia) 2023bee in NGC~2708 ( Mpc), finding excess flux in the first d…
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…
A super-Chandrasekhar mass type Ia supernova progenitor at 49 pc set to detonate in 23 Gyr
James Munday, Ruediger Pakmor, Ingrid Pelisoli +9
Double white dwarf binaries are a leading explanation to the origin of type Ia supernovae, but no system exceeding the Chandrasekhar mass limit (1.4 M) has been found that…
ASASSN-14lp: two possible solutions for the observed UV suppression
Barnabás Barna, Talytha Pereira, Stefan Taubenberger +10
We test the adequacy of ultraviolet (UV) spectra for characterizing the outer structure of Type Ia supernova (SN) ejecta. For this purpose, we perform spectroscopic analysis for AS…
SN 2016dsg: A Thermonuclear Explosion Involving A Thick Helium Shell
Yize Dong, Stefano Valenti, Abigail Polin +29
A thermonuclear explosion triggered by a helium-shell detonation on a carbon-oxygen white dwarf core has been predicted to have strong UV line blanketing at early times due to the…
Observations of the low-luminosity Type Iax supernova 2019gsc: a fainter clone of SN 2008ha?
Lina Tomasella, Maximilian Stritzinger, Stefano Benetti +9
We present optical photometric and spectroscopic observations of the faint-and-fast evolving type Iax SN 2019gsc, extending from the time of g-band maximum until about fifty days p…
