Limits on Dark Matter Annihilation Signals from the Fermi LAT 4-year Measurement of the Isotropic Gamma-Ray Background
The Fermi LAT Collaboration, M. Ackermann, M. Ajello +110
We search for evidence of dark matter (DM) annihilation in the isotropic gamma-ray background (IGRB) measured with 50 months of Fermi Large Area Telescope (LAT) observations. An im…
The role of the accretion disk, dust, and jets in the IR emission of low-luminosity AGN
R. E. Mason, C. Ramos Almeida, N. A. Levenson +2
We use recent high-resolution infrared (IR; 1 - 20 micron) photometry to examine the origin of the IR emission in low-luminosity active galactic nuclei (LLAGN). The data are compar…
Short timescale variations of the Hα double-peaked profile of the nucleus of NGC 1097
Jaderson S. Schimoia, Thaisa Storchi-Bergmann, Rodrigo S. Nemmen +2
The broad (FWHM ~ 10,000 km/s) double-peaked Hα profile from the LINER/Seyfert 1 nucleus of NGC 1097 was discovered in 1991, and monitored for the following 11 years. The profile s…
Spectral Energy Distribution Models for Low-luminosity Active Galactic Nuclei in LINERs
Rodrigo Nemmen, Thaisa Storchi-Bergmann, Michael Eracleous
Low-luminosity active galactic nuclei (LLAGNs) represent the bulk of the AGN population in the present-day universe and they trace the low-level accreting supermassive black holes.…
The New Generation Atlas of Quasar Spectral Energy Distributions from Radio to X-rays
Zhaohui Shang, Michael Brotherton, Beverley J Wills +14
We have produced the next generation of quasar spectral energy distributions (SEDs), essentially updating the work of Elvis et al. (1994) by using high-quality data obtained with s…
Quasar bolometric corrections: theoretical considerations
Rodrigo S. Nemmen, Michael S. Brotherton
Bolometric corrections based on the optical-to-ultraviolet continuum spectrum of quasars are widely used to quantify their radiative output, although such estimates are affected by…
