      We present a study of the HII regions in the galaxy NGC 6754 from a two pointing mosaic comprising 197 637 individual spectra, using integral field spectroscopy recently acquired with the MUSE instrument during its Science ...

      We present a statistical analysis of the environments of 11 supernovae (SNe) which occurred in six nearby galaxies (z less than or similar to 0.016). All galaxies were observed with MUSE, the high spatial resolution ...

(IOP Publishing, 2016)
      Supernova (SN) iPTF13bvn in NGC 5806 was the first Type Ib SN to have been tentatively associated with a progenitor in pre-explosion images. We performed deep ultraviolet (UV) and optical Hubble Space Telescope observations ...

      We present a Hubble diagram of SNe II using corrected magnitudes derived only from photometry, with no input of spectral information. We use a data set from the Carnegie Supernovae Project I for which optical and ...

      Aims. We present and analyse late-time observations of the Type-Ib supernova with possible pre-supernova progenitor detection, iPTF13bvn, which were done similar to 300 days after the explosion. We discuss them in the ...
    • Kankare, E.; Kotak, R.; Pastorello, A.; Fraser, M.; Mattila, S.; Smartt, S.; Bruce, A.; Chambers, K.; Elias Rosa, N.; Flewelling, H.; Fremling, C.; Harmanen, J.; Huber, M.; Jerkstrand, A.; Kangas, T.; Kuncarayakti, Hanindyo; Magee, M.; Magnier, E.; Polshaw, J.; Smith, K.; Sollerman, j.; Tomasella, L. (EDP Sciences, 2015)
      We present our findings on a supernova (SN) impostor, SNHunt248, based on optical and near-IR data spanning ∼15 yr before discovery, to ∼1 yr post-discovery. The light curve displays three distinct peaks, the brightest ...
    • Folatelli, Gastón; Bersten, Melina C.; Kuncarayakti, Hanindyo; Benvenuto, Omar G.; Maeda, Keiichi; Nomoto, Ken’ichi (IOP Publishing, 2015)
      Hubble Space Telescope observations of the site of the supernova (SN) SN 2008ax obtained in 2011 and 2013 reveal that the possible progenitor object detected in pre-explosion images was in fact multiple. Four point sources ...

      We present rapidly rising transients discovered by a high-cadence transient survey with the Subaru telescope and Hyper Suprime-Cam. We discovered five transients at z=0.384–0.821, showing a rate of rise faster than 1 ...
    • Anderson, Joseph; James, Phil A.; Habergham, Stacey; Galbany, Lluis; Kuncarayakti, Hanindyo (Cambridge Univ Press, 2015)
      Mapping the diversity of SNe to progenitor properties is key to our understanding of stellar evolution and explosive stellar death. Investigations of the immediate environments of SNe allow statistical constraints to be ...
