GEMINGA: NEW OBSERVATIONS AT LOW RADIO FREQUENCIES

GEMINGA: NEW OBSERVATIONS AT LOW RADIO FREQUENCIES

After nearly 10 years, we have succeeded to detect radio emission from Geminga more again. In this report we present new evidence for presence of radio emission from Geminga in the range 42-112 MHz. The observations were carried out on two sensitive transit radio telescopes We used three new digital...
