• THEMIS observation of multiple dipolarization fronts and associated wave characteristics in the near‐Earth magnetotail (2009, background): “Recently, state-of-the-art kinetic simulations with open boundary conditions reproduced the asymmetric bipolar signature of DF [ Sitnov et al., 2009 ].”
• Wave and particle characteristics of earthward electron injections associated with dipolarization fronts (2010, result): “... 2009], which is near the ion inertial length of 300 km. [8] It is important to recall that the electron injection and thin plasma boundary layer are closely related to the magnetic field dipolarization fronts and BBFs (Figure 2). The dipolarizations at P1 and P2 are preceded by small decreases i”
• Accelerated ions ahead of earthward propagating dipolarization fronts (2010, background): “[4] Kinetic simulations [ Sitnov et al., 2009 ] suggest that most of the observed dipolarization signatures, including the steep front, the Bz dip preceding the front, and the gradual Bz decrease that follows it, could be reproduced by transient reconnection in the magnetotail thin current sheet.”
• Bursty bulk flows and dipolarization in MHD simulations of magnetotail reconnection (2011, background): “Sometimes the observed reduction of Bz involves negative Bz. In that case, the dip may be associated with secondary reconnection involving formation of a small magnetic island or flux rope earthward of the main reconnection site [Schindler, 1974; Slavin et al., 2003; Sitnov et al., 2009 ].”
• On the current sheets surrounding dipolarizing flux bundles in the magnetotail: The case for wedgelets (2013, background): “DFBs are generated at around 20–50 RE downtail, most likely by reconnection [e.g., Semenov et al., 2005; Sitnov et al., 2009], and then move earthward, likely by an interchange process [e.g., Chen and Wolf, 1999; Pritchett and Coroniti, 2010].”
• Occurrence rate of earthward‐propagating dipolarization fronts (2012, background): “As a boundary with typical scale of ion inertial length (c/wpi), the DF has been suggested to be associated with transient reconnection [Sitnov et al., 2009] and substorms [Baumjohann et al., 1999].”
• THEMIS observations of an earthward‐propagating dipolarization front (2009, methodology): “The observed spatial scales of the DF and the Bz-dip (� di )a re similar to those resulting from PIC simulations [ Sitnov et al., 2009 ].”
• Dipolarization fronts as a consequence of transient reconnection: In situ evidence (2013, background): “Transient reconnection, triggered by the external perturbation [Sitnov et al., 2009; Pritchett, 2010; Sitnov and Swisdak, 2011], changes the topology of magnetic field and then produces the DFs.”
