The radio galaxy NGC 1275 was recently observed by VERITAS at energies above 100 GeV for about 8 hr. No VHE gamma-ray emission was detected by VERITAS from NGC 1275. A 99% confidence level upper limit of 2.1% of the Crab Nebula flux level is obtained at the decorrelation energy of approximately 340 GeV, corresponding to 19% of the power-law extrapolation of the Fermi Large Area Telescope result.galaxies individual NGC 1275 3C 84 Perseus Agalaxies Seyfertgamma rays observations10.1088/0004-637X/706/2/L275http://adsabs.harvard.edu/abs/2009ApJ...706L.275A2009ApJ...706L.275A
