Axionlike particles (ALPs) are hypothetical light (sub-eV) bosons predicted in some extensions of the Standard Model of particle physics. In astrophysical environments comprising high-energy gamma rays and turbulent magn...

Aims. We analyze INTEGRAL-ISGRI data in order to probe the hard X-ray emission (above 20 keV) from point sources in the Cyg OB2 region and to investigate the putative non-thermal high-energy emission from early-type star...

HD 195592 is an O-type supergiant star, known as a well-established runaway. Recently, a Fermi γ-ray source (2FGL J2030.7+4417) with a position compatible with that of HD 195592 has been reported. Our goal is to explore...

Star-forming galaxies (SFGs) are a subclass of γ -ray emitters, and a correlation between their γ -ray luminosity ( L _γ ) and the total infrared (IR) luminosity ( L _IR ) has been established based on the Fermi Large...

Among thousands of extragalactic γ -ray emitters, only a handful of distant ( z  > 3) sources are detected. Yet they are crucial probes, shedding light on the cosmic evolution of jets of active galactic nuclei and the...

Abstract In this research the absorbed dose by the thyroid gland of radioiodine 131I during treatment of the thyroid cancer after total or partial remove of the thyroid gland by operation, the radioiodine is concentrated...

M2 cotton seeds of mosaic leaves mutants (MC2 and MC3) plants (Gossypium. hirsutum – Coker-310) were used to obtain M3 plants for study the productivity and technological characters. The MC2 mutant was obtained after e...
