Query: The MAVERIC survey: A transitional millisecond pulsar candidate in
  Terzan 5   Transitional millisecond pulsars are accreting millisecond pulsars that
switch between accreting X-ray binary and millisecond radio pulsar states. Only
a handful of these objects have been identified so far. Terzan 5 CX1 is a
variable hard X-ray source in the globular cluster Terzan 5. In this paper, we
identify a radio counterpart to CX1 in deep Very Large Array radio continuum
data. Chandra observations over the last fourteen years indicate that CX1 shows
two brightness states: in 2003 and 2016 the source was the brightest X-ray
source in the cluster (at L$_X \sim 10^{33}$ erg s$^{-1}$), while in many
intermediate observations, its luminosity was almost an order of magnitude
lower. We analyze all available X-ray data of CX1, showing that the two states
are consistent with the spectral and variability properties observed for the
X-ray active and radio pulsar states of known transitional millisecond pulsars.
Finally, we discuss the prospects for the detection of CX1 as a radio pulsar in
existing timing data.
