Frenkel-Gross' irregular connection and Heinloth-Ng\^{o}-Yun's are the   same
  We show that the irregular connection on $\bbG_m$ constructed by Frenkel-Gross (2009) and the one constructed by Heinloth-Ng\^{o}-Yun (arXiv:1005.2765) are the same, which confirms the Conjecture 2.14 of arXiv:1005.2765.
