Query: Detection and Flux Density Measurements of the Millisecond Pulsar
  J2145-0750 below 100 MHz   We present flux density measurements and pulse profiles for the millisecond
pulsar PSR J2145-0750 spanning 37 to 81 MHz using data obtained from the first
station of the Long Wavelength Array. These measurements represent the lowest
frequency detection of pulsed emission from a millisecond pulsar to date. We
find that the pulse profile is similar to that observed at 102 MHz. We also
find that the flux density spectrum between ~40 MHz to 5 GHz is suggestive of a
break and may be better fit by a model that includes spectral curvature with a
rollover around 730 MHz rather than a single power law.
