“…Again, this indicates that a strict luminosity cutoff is not a suitable way to select SLSNe. We also note that the peak luminosities of our faintest SLSNe are comparable to some of the most luminous Type Ic-BL SNe discovered (e.g., Sanders et al 2012;Whitesides et al 2017), suggesting that there is not a true luminosity "gap" between SLSNe and core-collapse SNe.…”

AbstractWe present light curves and classification spectra of 17 hydrogen-poor superluminous supernovae (SLSNe) from the Pan-STARRS1 Medium Deep Survey (PS1 MDS). Our sample contains all objects from the PS1MDS sample with spectroscopic classification that are similar to either of the prototypes SN 2005ap or SN 2007bi, without an explicit limit on luminosity. With a redshift range z 0.3 1.6 < < , PS1MDS is the first SLSN sample primarily probing the high-redshift population; our multifilter PS1 light curves probe the rest-frame UV emission, and hence the peak of the spectral energy distribution. We measure the temperature evolution and construct bolometric light curves, and find peak luminosities of 0.5 5 10 44 ( -) ergs −1 and lower limits on the total radiated energies of 0.3 2 10 51 ( -) erg. The light curve shapes are diverse, with both rise and decline times spanning a factor of ∼5 and several examples of double-peaked light curves. When correcting for the flux-limited nature of our survey, we find a median peak luminosity at 4000Å of M 21.1 mag 4000 = -and a spread of 0.7 mag s = .

“…For some luminous and rapidly evolving transients such as iPTF16asu (Whitesides et al 2017), and AT 2018cow (Prentice et al 2018b), powering through the spin down of a magnetar has been investigated. Since LSQ13ddu also displays a fast rise and high peak luminosity, we have tested if LSQ13ddu could be fit by a magnetar model.…”

“…Some rapidly evolving transients such as iPTF16asu (Whitesides et al 2017) have been investigated to see if their light curve could be powered by magnetar formation but it was found that the derived ejecta masses were too low (e.g. Arcavi et al 2016).…”

This paper describes the rapidly evolving and unusual supernova LSQ13ddu, discovered by the La Silla-QUEST survey. LSQ13ddu displayed a rapid rise of just 4.8±0.9 d to reach a peak brightness of −19.70±0.02 mag in the LSQgr band. Early spectra of LSQ13ddu showed the presence of weak and narrow He i features arising from interaction with circumstellar material (CSM). These interaction signatures weakened quickly, with broad features consistent with those seen in stripped-envelope SNe becoming dominant around two weeks after maximum. The narrow He i velocities are consistent with the wind velocities of luminous blue variables but its spectra lack the typically seen hydrogen features. The fast and bright early light curve is inconsistent with radioactive 56 Ni powering but can be explained through a combination of CSM interaction and an underlying 56 Ni decay component that dominates the later time behaviour of LSQ13ddu. Based on the strength of the underlying broad features, LSQ13ddu appears deficient in He compared to standard SNe Ib.

“…INTEGRAL observations contributed to the triangulation, which allowed for establishing the association between GRB170105 and ATLAS17aeu (Svinkin et al 2017a). In general, INTEGRAL data are particularly useful to retrospectively search for GRB events, owing to its competitive and consistent omnidirectional sensitivity, stable background, and high duty cycle (see, e.g., a recent case studied by Whitesides et al 2017). GRB170105 was later found to be likely unrelated to GW170104 Stalder et al 2017).…”

INTEGRAL Observations of GW170104Savchenko Document VersionPublisher's PDF, also known as Version of record Link back to DTU Orbit Citation (APA): Savchenko, V., Ferrigno, C., Bozzo, E., Bazzano, A., Brandt, S., Chenevez, J., ... Ubertini, P. (2017 AbstractWe used data from the International Gamma-Ray Astrophysics Laboratory (INTEGRAL) to set upper limits on the γ-ray and hard X-ray prompt emission associated with the gravitational-wave event GW170104, discovered by the Laser Interferometer Gravitational-wave Observatory (LIGO)/Virgo collaboration. The unique omnidirectional viewing capability of the instruments on board INTEGRAL allowed us to examine the full 90% confidence level localization region of the LIGO trigger. Depending on the particular spectral model assumed and the specific position within this region, the upper limits inferred from the INTEGRAL observations range from F γ =1.9×10ergcm −2 (75 keV-2 MeV energy range). This translates into a ratio between the prompt energy released in γ-rays along the direction to the observer and the gravitational-wave energy of E γ /E GW <2.6×10 . Using the INTEGRAL results, we cannot confirm the γ-ray proposed counterpart to GW170104 by the Astro-Rivelatore Gamma a Immagini Leggero (AGILE) team with the mini-Calorimeter (MCAL) instrument. The reported flux of the AGILE/MCAL event, E2, is not compatible with the INTEGRAL upper limits within most of the 90% LIGO localization region. There is only a relatively limited portion of the sky where the sensitivity of the INTEGRAL instruments was not optimal and the lowest-allowed fluence estimated for E2 would still be compatible with the INTEGRAL results. This region was also observed independently by Fermi/Gamma-ray Burst Monitor and AstroSAT, from which, as far as we are aware, there are no reports of any significant detection of a prompt high-energy event.
