The long-lived Type IIn SN 2015da: Infrared echoes and strong interaction within an extended massive shell
L. Tartaglia, A. Pastorello, J. Sollerman +41
In this paper we report the results of the first four years of spectroscopic and photometric monitoring of the Type IIn supernova SN 2015da (also known as PSN J13522411+39412…
The optical and near-infrared spectrum of the Crab pulsar with X-shooter
J. Sollerman, J. Selsing, P. M. Vreeswijk +2
Pulsars are well studied all over the electromagnetic spectrum, and the Crab pulsar may be the most studied object in the sky. Nevertheless, a high-quality optical to near-infrared…
R-band light-curve properties of Type Ia supernovae from the (intermediate) Palomar Transient Factory
S. Papadogiannakis, A. Goobar, R. Amanullah +15
We present the best 265 sampled R-band light curves of spectroscopically identified Type Ia supernovae (SNe) from the Palomar Transient Factory (PTF; 2009-2012) survey and the inte…
Analysis of broad-lined Type Ic supernovae from the (intermediate) Palomar Transient Factory
F. Taddia, J. Sollerman, C. Fremling +18
We study 34 Type Ic supernovae that have broad spectral features (SNe Ic-BL). We obtained our photometric data with the Palomar Transient Factory (PTF) and its continuation, the in…
A UV Resonance Line Echo from a Shell Around a Hydrogen-Poor Superluminous Supernova
R. Lunnan, C. Fransson, P. M. Vreeswijk +21
Hydrogen-poor superluminous supernovae (SLSN-I) are a class of rare and energetic explosions discovered in untargeted transient surveys in the past decade. The progenitor stars and…
Energetic eruptions leading to a peculiar hydrogen-rich explosion of a massive star
Iair Arcavi, D. Andrew Howell, Daniel Kasen +50
Every supernova hitherto observed has been considered to be the terminal explosion of a star. Moreover, all supernovae with absorption lines in their spectra show those lines decre…
SN 2012aa - a transient between Type Ibc core-collapse and superluminous supernovae
R. Roy, J. Sollerman, J. M. Silverman +21
Context: Research on supernovae (SNe) over the past decade has confirmed that there is a distinct class of events which are much more luminous (by mag) than canonical core-…
PTF12os and iPTF13bvn. Two stripped-envelope supernovae from low-mass progenitors in NGC 5806
C. Fremling, J. Sollerman, F. Taddia +19
We investigate two stripped-envelope supernovae (SNe) discovered in the nearby galaxy NGC 5806 by the (i)PTF. These SNe, designated PTF12os/SN 2012P and iPTF13bvn, exploded at a si…
Metallicity at the explosion sites of interacting transients
F. Taddia, J. Sollerman, C. Fremling +8
Context. Some circumstellar-interacting (CSI) supernovae (SNe) are produced by the explosions of massive stars that have lost mass shortly before the SN explosion. There is evidenc…
No trace of a single-degenerate companion in late spectra of SNe 2011fe and 2014J
P. Lundqvist, A. Nyholm, F. Taddia +9
Left-over, ablated material from a possible non-degenerate companion can reveal itself after about one year in spectra of Type Ia SNe (SNe Ia). We have searched for such material i…
