      Context. The study of the integrated properties of star-forming galaxies is central to understand their formation and evolution. Some of these properties are extensive and therefore their analysis require totally covering ...

(The American Astronomical Society, 2016-12-01)
      We present the first results of the High Cadence Transient Survey (HiTS), a survey for which the objective is to detect and follow-up optical transients with characteristic timescales from hours to days, especially the ...
    • The lowest-metallicity type II supernova from the highest-mass red supergiant progenitor 
      Anderson, P.; Dessart, L.; Gutierrez, C.; Kruhler, T.; Galbany, Lluis; Jerkstrand, A.; Smartt, S.; Contreras, C.; Morrell, N.; Phillips, M.; Stritzinger, M.; Hsiao, E.; González Gaitán, Santiago; Agliozzo, C.; Castellon, Sergio; Chambers, K.; Chen, T.; Flewelling, H.; González, C.; Hosseinzadeh, G.; Huber, M.; Fraser, M.; Inserra, C.; Kankare, E.; Mattila, S.; Magnier, E.; Maguire, K.; Lowe, T.; Sollerman, J.; Sullivan, M.; Young, D.; Valenti, S. (Nature Publishing Group, 2018-07)
      Red supergiants have been confirmed as the progenitor stars of the majority of hydrogen-rich type II supernovae(1). However, while such stars are observed with masses > 25 M-circle dot (ref. (2)), detections of > 18 M-circle ...

      Magee, M. R.; Kotak, R.; Sim, S. A.; Kromer, M.; Rabinowitz, D.; Smartt, S. J.; Baltay, C.; Campbell, H. C.; Chen, T. W.; Fink, M.; Gal Yam, Avishay; Galbany, Lluis; Hillebrandt, W.; Inserra, C.; Kankare, E.; Le Guillou, L.; Lyman, J. D.; Maguire, K.; Pakmor, R.; Ropke, F. K.; Ruiter, A. J.; Seitenzahl, I. R.; Sullivan, M.; Valenti, S.; Young, D. R. (EDP Sciences, 2016)
      We present results based on observations of SN 2015H which belongs to the small group of objects similar to SN 2002cx, otherwise known as type Iax supernovae. The availability of deep pre-explosion imaging allowed us to ...
