The MAGIC Collaboration reports the first detection of very-high-energy (VHE; E>100 GeV) gamma-ray emission from PKS1413+135 (14 15 58.82 +13 20 23.71, J2000.0). The preliminary analysis of the MAGIC data taken on 2022/01/12 resulted in the detection of PKS1413+135 with a statistical significance more than 5 standard deviations, and indicates a flux of about 15% of the flux from the Crab nebula above 150 GeV.
PKS1413+135 is a blazar located at redshift estimated in the range of 0.247-0.5 (Readhead et al 2021). It is most likely located behind a Seyfert galaxy that is possibly creating millilensing effects (Peirson et al. 2022).
The MAGIC observations were motivated by the enhanced GeV flux derived with a dedicated analysis pipeline on Fermi-LAT data from blazars.
MAGIC observations on PKS1413+135 will continue during the next days, multiwavelength observations are encouraged. The MAGIC contact persons for these observations are O. Blanch (blanch@ifae.es) and J. Sitarek (jsitarek@uni.lodz.pl)
The preliminary analysis has been performed by the Flare Advocate Jelena Striskovic (jelena.striskovic@gmail.com).
MAGIC is a system of two 17m-diameter Imaging Atmospheric Cherenkov Telescopes located at the Canary island of La Palma, Spain, and designed to perform gamma-ray astronomy in the energy range from 50 GeV to greater than 50 TeV.
