An environmental analysis of supernova iPTF13bvn with HST and MUSE
Adam J. Singleton, Justyn R. Maund, Ning-Chen Sun
Searches for supernovae (SNe) progenitors have relied on a direct detection of the star in fortuitous pre-explosion images. We propose an alternative method, using a combination of…
Self-Supervised Clustering on Image-Subtracted Data with Deep-Embedded Self-Organizing Map
Y. -L. Mong, K. Ackley, T. L. Killestein +45
Developing an effective automatic classifier to separate genuine sources from artifacts is essential for transient follow-ups in wide-field optical surveys. The identification of t…
GRB 080928 afterglow imaging and spectro-polarimetry
R. Brivio, S. Covino, P. D'Avanzo +5
Among the large variety of astrophysical sources that we can observe, gamma-ray bursts (GRBs) are the most energetic of the whole Universe. The definition of a general picture desc…
Origins of Type Ibn SNe 2006jc/2015G in interacting binaries and implications for pre-SN eruptions
Ning-Chen Sun, Jusytn R. Maund, Ryosuke Hirai +2
Type Ibn supernovae (SNe Ibn) are intriguing stellar explosions whose spectra exhibit narrow helium lines with little hydrogen. They trace the presence of circumstellar material (C…
PESSTO : survey description and products from the first data release by the Public ESO Spectroscopic Survey of Transient Objects
S. J. Smartt, S. Valenti, M. Fraser +99
The Public European Southern Observatory Spectroscopic Survey of Transient Objects (PESSTO) began as a public spectroscopic survey in April 2012. We describe the data reduction str…
SN 2012ec: mass of the progenitor from PESSTO follow-up of the photospheric phase
C. Barbarino, M. Dall'Ora, M. T. Botticella +32
We present the results of a photometric and spectroscopic monitoring campaign of SN 2012ec, which exploded in the spiral galaxy NGC 1084, during the photospheric phase. The photome…
On the progenitor of the Type Ic SN 2013dk in the Antennae Galaxies
Nancy Elias-Rosa, Andrea Pastorello, Justyn R. Maund +7
We report the results of our search for the progenitor candidate of SN 2013dk, a Type Ic supernova (SN) that exploded in the Antennae Galaxy system. We compare pre-explosion Hubble…
Optical and near-infrared observations of SN 2011dh - The first 100 days
M. Ergon, J. Sollerman, M. Fraser +26
We present optical and near-infrared (NIR) photometry and spectroscopy of the Type IIb supernova (SN) 2011dh for the first 100 days. We complement our extensive dataset with SWIFT…
Supernova 2012ec: Identification of the progenitor and early monitoring with PESSTO
J. R. Maund, M. Fraser, S. J. Smartt +13
We present the identification of the progenitor of the Type IIP SN 2012ec in archival pre-explosion HST WFPC2 and ACS/WFC F814W images. The properties of the progenitor are further…
Low-Resolution Spectroscopy of Gamma-ray Burst Optical Afterglows: Biases in the Swift Sample and Characterization of the Absorbers
J. P. U. Fynbo, P. Jakobsson, J. X. Prochaska +39
(Abridged). We present a sample of 77 optical afterglows (OAs) of Swift detected GRBs for which spectroscopic follow-up observations have been secured. We provide linelists and equ…
