Malofeev et. al. (ATEL #501) reported the detection of radio pulses from X-ray pulsar J1852+0040 at the frequency of 111.23 MHz. I also made observations of this object using the same telescope.
Observations were performed from April to May 2005 with the Large Phase Array (BSA) Radio Telescope at Pushchino Radio Astronomy Observatory of Lebedev Physical Institute at a frequency of 111 MHz. BSA is a transit telescope with an effective area of about 15,000 square meters. One linear polarization was received. I used a 128-channel receiver with channel bandwidth 20 kHz. The sampling interval was 2.56 ms and the receiver time constant was tau = 3 ms. The duration of each observation session was about 3 min (1600 pulsar periods). A total of 27 observations were carried out in the mode of recording single pulses.
Folding of all 27 observation sessions using parameters of Malofeev et. al. (ATEL #501) gives negative result for each observation session - there are no pulses with S/N > 5 at the dispesion measure of 110 pc/cm(3). Unfortunately, I can't confirm the detection of radio emission from X-ray pulsar PSR J1852+0040.
