Studying the Ultraviolet Spectrum of the First Spectroscopically Confirmed Supernova at redshift two
M. Smith, M. Sullivan, R. C. Nichol +87
We present observations of DES16C2nm, the first spectroscopically confirmed hydrogen-free superluminous supernova (SLSN-I) at redshift z~2. DES16C2nm was discovered by the Dark Ene…
SN 2017dio: a type-Ic supernova exploding in a hydrogen-rich circumstellar medium
Hanindyo Kuncarayakti, Keiichi Maeda, Christopher J. Ashall +42
SN 2017dio shows both spectral characteristics of a type-Ic supernova (SN) and signs of a hydrogen-rich circumstellar medium (CSM). Prominent, narrow emission lines of H and He are…
Serendipitous discovery of an optical emission line jet in NGC\,232
C. Lopez-Coba, S. F. Sanchez, I. Cruz-Gonzalez +9
We report the detection of a highly collimated linear emission-line structure in the spiral galaxy NGC\,232 through the use of integral field spectroscopy data from the All-weather…
No surviving companion in Kepler's supernova
Pilar Ruiz-Lapuente, Francesco Damiani, Luigi R. Bedin +5
We have surveyed Kepler's supernova remnant in search of the companion star of the explosion. We have gone as deep as 2.6 solar luminosities in the stars within 20% of the radius o…
Type II supernova spectral diversity II: Spectroscopic and photometric correlations
Claudia P. Gutiérrez, Joseph P. Anderson, Mario Hamuy +7
We present an analysis of observed trends and correlations between a large range of spectral and photometric parameters of more than 100 type II supernovae (SNe~II), during the pho…
Type II supernova spectral diversity I: Observations, sample characterization and spectral line evolution
Claudia P. Gutiérrez, Joseph P. Anderson, Mario Hamuy +23
We present 888 visual-wavelength spectra of 122 nearby type II supernovae (SNe II) obtained between 1986 and 2009, and ranging between 3 and 363 days post explosion. In this first…
Serendipitous discovery of RR Lyrae stars in the Leo V ultra-faint galaxy
Gustavo E. Medina, Ricardo R. Muñoz, A. Katherina Vivas +9
During the analysis of RR Lyrae stars discovered in the High cadence Transient Survey (HiTS) taken with the Dark Energy Camera at the 4-m telescope at Cerro Tololo Inter-American O…
Emission-line Diagnostics of Nearby HII Regions Including Supernova Hosts
Lin Xiao, J. J. Eldridge, Elizabeth Stanway +1
We present a new model of the optical nebular emission from HII regions by combin- ing the results of the Binary Population and Spectral Synthesis (bpass) code with the photoion- i…
