    "abstract": "Streamer discharges play a central role in electric breakdown of matter in\npulsed electric fields, both in nature and in technology. Reliable and fast\ncomputations of the minimal model for negative streamers in simple gases like\nnitrogen have recently been developed. However, photoionization was not\nincluded; it is important in air and poses a major numerical challenge. We here\nintroduce a fast and reliable method to include photoionization into our\nnumerical scheme with adaptice grids, and we discuss its importance for\nnegative streamers. In particular, we identify different propagation regimes\nwhere photoionization does or does not play a role.",
