cds-question@unistra.frgamma-ray-astronomysupernovaeredshiftedspectroscopyWe present the first systematic investigation of spectral properties of 17 Type Ic Supernovae (SNe Ic), 10 broad-lined SNe Ic (SNe Ic-bl) without observed gamma-ray bursts (GRBs), and 11 SNe Ic-bl with GRBs (SN-GRBs) as a function of time in order to probe their explosion conditions and progenitors. Using a number of novel methods, we analyze a total of 407 spectra, which were drawn from published spectra of individual SNe as well as from the densely time-sampled spectra of Modjaz+ (2014, J/AJ/147/99). In order to quantify the diversity of the SN spectra as a function of SN subtype, we construct average spectra of SNe Ic, SNe Ic-bl without GRBs, and SNe Ic-bl with GRBs. We find that SN 1994I is not a typical SN Ic, contrasting the general view, while the spectra of SN 1998bw/GRB 980425 are representative of mean spectra of SNe Ic-bl. We measure the ejecta absorption and width velocities using a new method described here and find that SNe Ic-bl with GRBs, on average, have quantifiably higher absorption velocities, as well as broader line widths than SNe without observed GRBs. In addition, we search for correlations between SN-GRB spectral properties and the energies of their accompanying GRBs. Finally, we show that the absence of clear He lines in optical spectra of SNe Ic-bl, and in particular of SN-GRBs, is not due to them being too smeared-out due to the high velocities present in the ejecta. This implies that the progenitor stars of SN-GRBs are probably free of the He-layer, in addition to being H-free, which puts strong constraints on the stellar evolutionary paths needed to produce such SN-GRB progenitors at the observed low metallicities.2016ApJ...832..108Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/832/108CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/827/90 : Spectroscopy of SNe Ib, IIb and Ic (Liu+, 2016)J/MNRAS/450/905 : New SNe in SDSS DR9 (Graur+, 2015)J/A+A/574/A60 : Light curve templates of SNe Ib/c from SDSS (Taddia+, 2015)J/ApJS/213/19 : Optical and near-IR light curves of 64 SNe (Bianco+, 2014)J/AJ/147/99 : Spectrosc. of 73 stripped core-collapse SNe (Modjaz+, 2014)J/ApJ/774/114 : GRB 081007 and GRB 090424 light curves (Jin+, 2013)J/MNRAS/430/1746 : 90 new SNIa from SDSS DR7 (Graur+, 2013)J/MNRAS/425/1789 : Berkeley supernova Ia program.
