 compare the linear fits -> within uncertainty 2-D test (in limited M range): is there anything intrinsic about the M − Z relation of SN-GRB hosts, or are they similar to the SDSS galaxies just losing the ability to produce GRBs at a certain Z threshold 
 cross-match test (Roosland 2015) measures Mahalanobis distance between points-> within uncertainty

  20. Host Galaxies of PTF Ic & Ic-bl - jet production

    federica bianco, UDel | fedhere Motivation Data & Method Results Conclusions 1. SN Ic-BL and SN-GRB prefer (statistically) similar low Z environments (this work) 2. Barnes+2017 (w FBB & Modjaz): perform an end-to-end simulation of SN- GRBs via state- of-the-art hydrodynamic and spectral synthesis simulations and produces a SN-BL lightcurve 3. Modjaz, Liu, Bianco. Graur 2016: SNe Ic-bl w/o GRBs have lower velocities and less broadened lines than SNe-GRBs We propose: - SN-Ic do not produce jets (as claimed in Sobacchi+2017) - Both Ic-BL and SN-GRB produce jet. Jets are choked in Ic-BL Limits to the study: - Sample size (especially SN-GRB and complete metallicity samples) - degeneracy in parameters that complicates interpretation

  22. Host Galaxies of PTF Ic & Ic-bl - jet production

    federica bianco, UDel | fedhere Motivation Data & Method Results metallicities, SFRs and M∗s of our PTF SN Ic-bl hosts are statistically comparable to those of SN-GRBs, but significantly lower than those of the PTF SNe Ic. The mass-metallicity relations as defined by the SNe Ic-bl and SN-GRBs are not significantly different from the same relations as defined by the SDSS galaxies, in contrast to claims by earlier works. Our findings point towards low metallicity as a crucial ingredient for SN Ic- bl and SN-GRB production since we are able to break the degeneracy between high SFR and low metallicity. We suggest that the PTF SNe Ic-bl may have produced jets that were choked inside the star or were able break out of the star as GRBs that either were off-axis GRBs or low-luminosity radio-quiet on-axis GRBs.
