High Energy Gamma-ray Emission from Blazars: Egret Observations
We will present a summary of the observations of blazars by the Energetic Gamma Ray Experiment Telescope (EGRET) on the Compton Gamma Ray Observatory (CGRO). EGRET has detected high energy γray emission at energies greater than 100 MeV from more that 50 blazars. These sources show inferred isotropic luminosities as large as 3× 10 ergs s. One of the most remarkable characteristics of the EGRET o...
متن کاملHidden Blazars and Emission Line Variability of High Redshift Quasars
El resumen será traducido al español por los editores. We have carried out a survey to search for hidden blazars in a sample of z∼2 radio-loud quasars. The idea is based on our prediction that we should be able to see large CIV line variability not associated with observed continuum variations or most other emission lines in every radio-loud quasar. Here we report the initial results including ...
متن کاملCO emission from high redshift
Future observations with ALMA will be able to detect star-forming primordial galaxies, and perhaps even their dwarf spheroidal satellites, in CO emission lines at redshifts approaching 10. These observations will compliment other tools designed to study the dawn of galaxy formation, such as NGST and FIRST.
متن کاملIntrinsic Constraints on Very High Energy Emission in Gamma-ray Loud Blazars
Photons with very high energy up to TeV (VHE) emitted from active galactic nuclei (AGNs) provide some invaluable information of the origin of γ-ray emission. Although 66 blazars have been detected by EGRET, only three low redshift X-ray selected BL Lacs (Mrk 421, Mrk 501, and 1ES 2344+514) are conclusive TeV emitters (PKS 2155-304 is a potential TeV emitter) since VHE photons may be absorbed by...
متن کاملBroadband Observations of High Redshift Blazars
We present a multi-wavelength study of four high redshift blazars, S5 0014+81 (z = 3.37), CGRaBS J0225+1846 (z = 2.69), BZQ J1430+4205 (z = 4.72), and 3FGL J1656.2−3303 (z = 2.40), using the quasi-simultaneous data from Swift, NuSTAR, and Fermi-Large Area Telescope (LAT) and also the archival XMM-Newton observations. Other than 3FGL J1656.2−3303, none of the sources were known as γ-ray emitters...
