Estefania Padilla Gonzalez, Yael Dgany(TAU), Jamison Burke, Daichi Hiramatsu, D. Andrew Howell, Curtis McCully, Craig Pellegrino report/s a classification of object: SN 2016elg
Type: SN IaRedshift: 0.054027
Remarks: Using Superfit (Howell et al. 2005, ApJ, 634, 1190) and SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find best fits to SNe Ia near maximum light, including SN 2005hf 8 days after peak. The supernova is closest to WISEA J141033.88-005918.0 (z = 0.058596, 2004SDSS2.C...0000:, value from NED). Adopting this redshift we measure a Si II 6355 velocity of approximately 10,000 km/s. Adopting the distance modulus computed from this redshift (36.86 mag), the r-band absolute magnitude of the object roughly coeval with the spectrum is -18.2 (apparent magnitude 18.64, from ZTF). This absolute magnitude and velocity is consistent with an SN Ia near maximum light.
