Discovery of a very highly extinguished supernova in a luminous infrared galaxy
E. Kankare, S. Mattila, S. Ryder +9
We report the discovery of a confirmed supernova (SN) and a supernova-candidate in near-infrared images from the ALTAIR/NIRI adaptive optics system on the Gemini-North Telescope an…
VLT detection of a red supergiant progenitor of the type IIP supernova 2008bk
S. Mattila, S. J. Smartt, J. J. Eldridge +3
We report the identification of a source coincident with the position of the nearby type II-P supernova (SN) 2008bk in high quality optical and near-infrared pre-explosion images f…
Core-collapse supernovae in low-metallicity environments and future all-sky transient surveys
D. R. Young, S. J. Smartt, S. Mattila +5
Aims: Massive stars in low-metallicity environments may produce exotic explosions such as long-duration gamma-ray bursts and pair-instability supernovae when they die as core-colla…
Detection efficiency and photometry in supernova surveys - the Stockholm VIMOS Supernova Survey I
J. Melinder, S. Mattila, G. Östlin +2
The aim of the work presented in this paper is to test and optimise supernova detection methods based on the optimal image subtraction technique. The main focus is on applying the…
The type IIb SN 2008ax: the nature of the progenitor
R. M. Crockett, J. J. Eldridge, S. J. Smartt +9
A source coincident with the position of the type IIb supernova (SN) 2008ax is identified in pre-explosion Hubble Space Telescope (HST) Wide Field Planetary Camera 2 observations i…
Massive stars exploding in a He-rich circumstellar medium. I. Type Ibn (SN 2006jc-like) events
A. Pastorello, S. Mattila, L. Zampieri +26
We present new spectroscopic and photometric data of the type Ibn supernovae 2006jc, 2000er and 2002ao. We discuss the general properties of this recently proposed supernova family…
