Issue Date: | 2016 | Journal: | THE ASTROPHYSICAL JOURNAL | Number: | 826 | Issue: | 1 | First Page: | 76 | Abstract: | MeV blazars are a sub-population of the blazar family, exhibiting larger-than-average jet powers, accretion luminosities, and black hole masses. Because of their extremely hard X-ray continua, these objects are best studied in the X-ray domain. Here, we report on the discovery by the Fermi Large Area Telescope and subsequent follow-up observations with NuSTAR, Swift, and GROND of a new member of the MeV blazar family: PMN J0641-0320. Our optical spectroscopy provides confirmation that this is a flat-spectrum radio quasar located at a redshift of z = 1.196. Its very hard NuSTAR spectrum (power-law photon index of ∼1 up to ∼80 keV) indicates that the emission is produced via inverse Compton scattering off of photons coming from outside the jet. The overall spectral energy distribution of PMN J0641-0320 is typical of powerful blazars and, using a simple one-zone leptonic emission model, we infer that the emission region is located either inside the broad line region or within the dusty torus. | URI: | http://hdl.handle.net/20.500.12386/24459 | URL: | https://iopscience.iop.org/article/10.3847/0004-637X/826/1/76 | ISSN: | 0004-637X | DOI: | 10.3847/0004-637X/826/1/76 | Bibcode ADS: | 2016ApJ...826...76A | Fulltext: | open |
