Photometric and spectroscopic evolution of the interacting transient AT 2016jbu (Gaia16cfr)
S. J. Brennan, M. Fraser, J. Johansson +68
We present the results from a high cadence, multi-wavelength observation campaign of AT 2016jbu (aka Gaia16cfr), an interacting transient. This dataset complements the current lite…
Type Ic supernovae from the (intermediate) Palomar Transient Factory
C. Barbarino, J. Sollerman, F. Taddia +8
Type Ic supernovae represent the explosions of the most stripped massive stars, but their progenitors and explosion mechanisms remain unclear. Larger samples of observed supernovae…
The Palomar Transient Factory Core-Collapse Supernova Host-Galaxy Sample. I. Host-Galaxy Distribution Functions and Environment-Dependence of CCSNe
Steve Schulze, Ofer Yaron, Jesper Sollerman +51
Several thousand core-collapse supernovae (CCSNe) of different flavors have been discovered so far. However, identifying their progenitors has remained an outstanding open question…
The Carnegie Supernova Project II. The shock wave revealed through the fog: The strongly interacting Type IIn SN 2013L
F. Taddia, M. D. Stritzinger, C. Fransson +21
We present ultra-violet to mid-infrared observations of the long-lasting Type IIn supernova (SN) 2013L obtained by the Carnegie Supernova Project II (CSP-II). The spectra of SN 201…
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…
Type IIn supernova light-curve properties measured from an untargeted survey sample
A. Nyholm, J. Sollerman, L. Tartaglia +19
We present a sample of supernovae Type IIn (SNe IIn) from the untargeted, magnitude-limited surveys of the Palomar Transient Factory (PTF) and its successor, the intermediate PTF (…
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…
The bumpy light curve of supernova iPTF13z
A. Nyholm, J. Sollerman, F. Taddia +10
A Type IIn supernova (SN) is dominated by the interaction of SN ejecta with the circumstellar medium (CSM). Some SNe IIn (e.g., SN 2006jd) have episodes of re-brightening ("bumps")…
AGN luminosity and stellar age -- two missing ingredients for AGN unification as seen with iPTF supernovae
Beatriz Villarroel, Anders Nyholm, Torgny Karlsson +4
Active Galactic Nuclei (AGN) are extremely powerful cosmic objects, driven by accretion of hot gas upon super-massive black holes. The zoo of AGN classes are divided into two major…
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…
Extragalactic SETI: The Tully-Fisher relation as a probe of Dysonian astroengineering in disk galaxies
E. Zackrisson, P. Calissendorff, S. Asadi +1
If advanced extraterrestrial civilizations choose to construct vast numbers of Dyson spheres to harvest radiation energy, this could affect the characteristics of their host galaxi…
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…
