A trio of gamma-ray burst supernovae:

Abstract: We present optical and near-infrared (NIR) photometry for three gamma-ray burst supernovae (GRB-SNe): GRB 120729A, GRB 130215A/SN 2013ez, and GRB 130831A/SN 2013fu. For GRB 130215A/SN 2013ez, we also present optical spectroscopy at t − t 0 = 16.1 d, which covers rest-frame 3000-6250 Å. Based on Fe  λ5169 and Si  λ6355, our spectrum indicates an unusually low expansion velocity of ∼4000-6350 km s −1 , the lowest ever measured for a GRB-SN. Additionally, we determined the brightness and shape of each accompa… Show more

“…SN 2013ez is also a notable outlier due to its low line velocity (4000 − 6000 km s −1 ), and inspection of its spectrum ( Fig. 5) reveals fewer broad features than other GRB-SNe, where it more closely resembles type Ic SNe rather than type IcBL [31]. Nevertheless, this relative grouping of line velocities may indicate similar density structure(s) in the ejecta of these SN, which in turn could indicate some general similarities in their pre-explosion progenitor configurations.…”

“…Swift X-ray and UV/optical Telescopes (XRT, UVOT), SKYNET, RATIR, ISON, NOT, and GTC observed GRB 130831A up to ≃ 10 7 s after the trigger, covering the emission of SN 2013fu associated with this event [2]. These UVOIR observations span the range 160-1800 nm.…”

“…The non-relativistic ejecta of SN 2013fu, the supernova associated with GRB 130831A, have kinetic energy of E SN = 1.9 × 10 52 erg [2]. Integrating the 0.3-10 keV luminosity of 130831A from the end of the prompt emission up to the steep drop, we find an X-ray energy release of E X = 2.9 × 10 50 erg.…”
