However, the coarse localizations of tens to a hundred square degrees provided by the Fermi GRB Monitor instrument have posed a formidable obstacle to locating the bursts' host galaxies, measuring their redshifts, and tracking their panchromatic afterglows. We have built a target-of-opportunity (TOO) mode for the intermediate Palomar Transient Factory (iPTF) in order to perform targeted searches for Fermi afterglows. Here, we present the results of one year of this program: 8 afterglow discoveries out of 35 searches. Two of the bursts with detected afterglows (GRBs 130702A and 140606B) were at low redshift (z=0.145 and 0.384, respectively) and had spectroscopically confirmed broad-line Type Ic supernovae. We present our broadband follow-up including spectroscopy as well as X-ray, UV, optical, millimeter, and radio observations. We study possible selection effects in the context of the total Fermi and Swift GRB samples. We identify one new outlier on the Amati relation. We find that two bursts are consistent with a mildly relativistic shock breaking out from the progenitor star rather than the ultra-relativistic internal shock mechanism that powers standard cosmological bursts. Finally, in the context of the Zwicky Transient Facility, we discuss how we will continue to expand this effort to find optical counterparts of binary neutron star mergers that may soon be detected by Advanced LIGO and Virgo.2015ApJ...806...52Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/806/52CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/134 : Atlas of Radio/X-ray associations (ARXA) (Flesch, 2010)J/ApJS/216/32 : Localizations of GRBs with Fermi GBM (Connaughton+, 2015)J/ApJS/211/13 : The second Fermi/GBM GRB catalog (4yr) (von Kienlin+, 2014)J/A+A/568/A19 : Photometry of 3 {gamma}-ray burst supernovae (Cano+, 2014)J/A+A/557/A100 : Fermi and Swift GRBs E_peak_-E_iso_ relation (Heussaff+, 2013)J/MNRAS/431/3608 : BeppoSAX/GRBM and Fermi/GBM long GRBs (Dichiara+, 2013)J/other/Nat/494.65 : SN 2010mc outburst before explosion (Ofek+, 2013)J/ApJS/207/39 : IPN supplement to the Fermi GBM (Hurley+, 2013)J/ApJS/199/18 : The Fermi GBM catalog (Paciesas+, 2012)J/ApJ/756/112 : Fermi/GBM GRB time-resolved spectral analysis (Lu+, 2012)J/ApJ/754/121 : GRBs from Fermi/GBM and LAT (The Fermi Team, 2012)J/ApJ/747/L5 : R-band observations of PTF 10vgv (Corsi+, 2012)J/ApJ/746/156 : Radio afterglow observations of GRBs (Chandra+, 2012)J/MNRAS/412/1441 : SNe luminosity functions (Li+, 2011)J/A+A/525/A53 : GBM parameters for detected FERMI bursts (Guetta+, 2011)J/ApJ/720/1513 : The afterglows of Swift-era GRBs.
