SN 2010ay is a luminous and broad-lined type Ic supernova within a low-metallicity host galaxy by Sanders, N., Soderberg, A., Valenti, S., Foley, R., Chornock, R., Chomiuk, L., Berger, E., Smartt, S., Hurley, K., Barthelmy, S., Levesque, E., Narayan, G., Botticella, M., Briggs, M., Connaughton, V., Terada, Y., Gehrels, N., Golenetskii, S., Mazets, E., Cline, T., von Kienlin, A., Boynton, W., Chambers, K., Grav, T., Heasely, J., Hodapp, K., Jedicke, R., Kaiser, N., Kirshner, R., Kudritzki, R., Luppino, G., Lupton, R., Magnier, E., Monet, D., Morgan, John, Onaka, P., Price, P., Stubbs, C., Tonry, J., Wainscoat, R., Waterson, Mark

“…The ratio of M Ni to M ej is ~2 times as large for SN 2010ay as typical GRB-SNe and may suggest an additional energy reservoir. The metallicity (log (O/H)PP04 + 12 = 8.19) of the explosion site within the host galaxy places SN 2010ay in the low-metallicity regime populated by GRB-SNe, and ~0.5(0.2) dex lower than that typically measured for the host environments of normal (broad-lined) SNe Ic. …”
