摘要：

Early results of the search for E-gamma > 1 PeV cosmic photons from point sources with the data of Carpet-2, an air-shower array equipped with a 175 m(2) muon detector, are presented. They include 95% CL upper limits on PeV photon fluxes from stacked directions of high-energy IceCube neutrino events and from four predefined sources, Crab, Cyg X-3, Mrk 421 and Mrk 501. An insignificant excess of events from Mrk 421 will be further monitored. Prospects of the use of the upgraded installation, Carpet-3 (410 m(2) muon detector), scheduled to start data taking in 2019, for searches of E-gamma > 100 TeV photons, are briefly discussed.
