H II region metallicity constraints near the site of the strongly lensed supernova “SN Refsdal” at redshift 1.49
We present the local H II region metallicity near the site of the recently discovered multiply lensed supernova (SN; "SN Refsdal") at redshift 1.49. "SN Refsdal" is located at the outer spiral arm (∼7 kpc) of the lensed host galaxy, which we previously reported to exhibit a steep negative galactocentric metallicity gradient. Based on our updated near-infrared integral field spectroscopic data, the gas-phase metallicity averaged in an intrinsic radius of ∼550 pc surrounding an H ii region ∼200...[Show more]
