iPTF Discoveries of Recent Type Ia Supernovae
S. Papadogiannakis, Tanja Petrushevska, 2015, other component parts

Abstract: 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.

iPTF discovery of a young Type Ia supernova: iPTF16auf
Tanja Petrushevska, 2016, other component parts

Abstract: We report the detection of a young supernova, designated as iPTF16auf, at RA=14:31:09.26 and Dec=+27:14:09.8 (J2000), in the vicinity of the star forming galaxy MRK 685 at spectroscopic redshift 0.015.

iPTF16geu: A multiply imaged, gravitationally lensed type Ia supernova
Ariel Goobar, Rahman Amanullah, S.R. Kulkarni, Tanja Petrushevska, 2017, original scientific article

Abstract: We report the discovery of a multiply-imaged gravitationally lensed Type Ia supernova, iPTF16geu, at redshift z = 0.409. This phenomenon could be iden- tified because the light from the stellar explosion was magnified more than fifty times by the curvature of space around matter in an intervening galaxy. We used high spatial resolution observations to resolve four images of the lensed supernova, approximately 0.300 from the center of the foreground galaxy. The observations probe a physical scale of ⇠1 kiloparsec, smaller than what is typical in other studies of extragalactic gravitational lensing. The large mag- nification and symmetric image configuration implies close alignment between the line-of-sight to the supernova and the lens. The relative magnifications of the four images provide evidence for sub-structures in the lensing galaxy.
