An Arecibo 327 MHz Search for Radio Pulsars and Bursts in the Dwarf
  Irregular Galaxies Leo A and T
  We have conducted an Arecibo 327 MHz search of two dwarf irregular galaxies
in the Local Group, Leo A and T, for radio pulsars and single pulses from fast
radio bursts and other giant pulse emitters. We detected no astrophysical
signals in this search, and we estimate flux density limits on both periodic
and burst emission. Our derived luminosity limits indicate that only the most
luminous radio pulsars known in our Galaxy and in the Magellanic Clouds (MCs)
would have been detectable in our search if they were at the distances of Leo A
and T. Given the much smaller stellar mass content and star formation rates of
Leo A and T compared to the Milky Way and the MCs, there are likely to be few
(if any) extremely luminous pulsars in these galaxies. It is therefore not
surprising that we detected no pulsars in our search.
