  Employing Solar Dynamic Observatory/Atmosphertic Imaging Assembly (AIA)
multi-wavelength images, we study an eruption of two crossing filaments, and
firstly report the current sheets (CSs) connecting the lower flare ribbons and
the upper erupting filaments. On July 8, 2014, two crossing filaments are
observed in the NOAA active region (AR) 12113. The lower-lying filament rises
first, and then meets the higher-lying one. Thereafter, both of them erupt
together. The filament eruption draws the overlying magnetic field lines
upward, leading to the approach of two legs, with opposite magnetic polarities,
of the overlying field lines. Two sets of bright CSs form at the interface of
these two legs, and magnetic reconnection takes place in the CSs producing the
underneath flare ribbons and post-flare loops. Several bright plasmoids appear
in the CSs, and propagate along the CSs bi-directionally. The CSs and plasmoids
are observed in AIA multi-wavelength channels, indicating that both of them
have been heated during the reconnection process, with hot and warm components.
Employing the differential emission measure (EM) analysis, we find that both
the temperature and EM of the CSs decrease from the flare arcades outward to
the erupting filaments, and those of the plasmoids are significantly larger
than the regions where no plasmoid is detected.
