A Novel Optimal Transport-Based Approach for Interpolating Spectral Time Series: Paving the Way for Photometric Classification of Supernovae
M. Ramirez, G. Pignata, Francisco Förster +7
This paper introduces a novel method for creating spectral time series, which can be used for generating synthetic light curves for photometric classification but also for applicat…
CSS161010: a luminous, fast blue optical transient with broad blueshifted hydrogen lines
Claudia P. Gutiérrez, Seppo Mattila, Peter Lundqvist +38
We present ultraviolet, optical and near-infrared photometric and optical spectroscopic observations of the luminous, fast blue optical transient (LFBOT), CSS161010:045834-081803 (…
Carnegie Supernova Project-II: Near-infrared spectral diversity and template of Type Ia Supernovae
Jing Lu, Eric Y. Hsiao, Mark M. Phillips +30
We present the largest and most homogeneous collection of near-infrared (NIR) spectra of Type Ia supernovae (SNe Ia): 339 spectra of 98 individual SNe obtained as part of the Carne…
Optical and Near-Infrared Observations of the Nearby Type Ia Supernova 2017cbv
Lingzhi Wang, Carlos Contreras, Maokai Hu +28
Supernova (SN) 2017cbv in NGC 5643 is one of a handful of type Ia supernovae (SNe~Ia) reported to have excess blue emission at early times. This paper presents extensive $BVRIYJHK_…
SN 2017ivv: two years of evolution of a transitional Type II supernova
C. P. Gutiérrez, A. Pastorello, A. Jerkstrand +39
We present the photometric and spectroscopic evolution of the Type II supernova (SN II) SN 2017ivv (also known as ASASSN-17qp). Located in an extremely faint galaxy (M ma…
Continuum Foreground Polarization and Na~I Absorption in Type Ia SNe
P. Zelaya, A. Clocchiatti, D. Baade +9
We present a study of the continuum polarization over the 400--600 nm range of 19 Type Ia SNe obtained with FORS at the VLT. We separate them in those that show Na I D lines at the…
Supernova 2010ev: A reddened high velocity gradient type Ia supernova
Claudia P. Gutiérrez, Santiago González-Gaitán, Gastón Folatelli +10
Aims. We present and study the spectroscopic and photometric evolution of the type Ia supernova (SN Ia) 2010ev. Methods. We obtain and analyze multi-band optical light curves and o…
A Hubble diagram from Type II Supernovae based solely on photometry: the Photometric-Colour Method
T. de Jaeger, S. González-Gaitán, J. P. Anderson +20
We present a Hubble diagram of type II supernovae using corrected magnitudes derived only from photometry, with no input of spectral information. We use a data set from the Carnegi…
Searching for light echoes due to CSM in SN Ia spectra
Sebastián Marino, Santiago González-Gaitán, Francisco Förster +3
We present an analytical model for light echoes (LEs) coming from circumstellar material (CSM) around Type Ia Supernovae (SNe Ia). Using this model we find two spectral signatures…
Defining Photometric Peculiar Type Ia Supernovae
S. Gonzalez-Gaitan, E. Y. Hsiao, G. Pignata +9
We present a new photometric identification technique for SN 1991bg-like type Ia supernovae (SNe Ia), i.e. objects with light-curve characteristics such as later primary maxima and…
Analysis of blue-shifted emission peaks in type II supernovae
J. P. Anderson, L. Dessart, C. P. Gutierrez +10
In classical P-Cygni profiles, theory predicts emission to peak at zero rest velocity. However, supernova spectra exhibit emission that is generally blue shifted. While this charac…
