The intermediate Palomar Transient Factory (ATel #4807)
reports the discovery and classification of the following Type Ia SNe.
Our automated candidate vetting to distinguish a real astrophysical source (1.0) from bogus artifacts (0.0) is powered by three generations of machine learning algorithms:
RB2 (Brink et al. 2013MNRAS.435.1047B), RB4 (Rebbapragada et al. 2015AAS...22543402R) and RB5 (Wozniak et al. 2013AAS...22143105W).
See ATel #7112 for additional details.
The classification spectra and additional details are made publicly available through WISeREP (Yaron & Gal-Yam 2012)
and the Transient Name Server.
IAU Name | iPTF Name | RA (J2000) | Dec (J2000) | Discovery date | Mag. | Abs.Mag. | Band | Redshift | Type | Spec. date | Phase | Instrument | Observers/Reducers | Scanner/s | RB2/RB4/RB5 | Notes
SN 2016ze | iPTF16e | 11:02:06.11 | +36:54:11.0 | 2016-02-02 | 19.61| -18.44 | PTF-g | 0.09 | SN Ia | 2016-02-02 | ~max | P200+DBSP | R. Lunnan / P. Vreeswijk | A. Horesh | 0.74/0.71/0.99 | (1)
[Dates are in UT; the estimated phase, if relevant, is with respect to peak light.]
(1) SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) provides good matches with several SNe Ia around maximum at z=0.09.
