A -ray determination of the Universe's star-formation history
LAT Collaboration, M. Ajello, K. Helgason +4
The light emitted by all galaxies over the history of the Universe produces the extragalactic background light (EBL) at ultraviolet, optical, and infrared wavelengths. The EBL is a…
Unresolved Gamma-Ray Sky through its Angular Power Spectrum
M. Ackermann, M. Ajello, L. Baldini +107
The gamma-ray sky has been observed with unprecedented accuracy in the last decade by the Fermi large area telescope (LAT), allowing us to resolve and understand the high-energy Un…
The relationship between the radio core-dominance parameter and spectral index in different classes of extragalactic radio sources (II)
Zhi-Yuan Pei, Jun-Hui Fan, Denis Bastieri +2
Active galactic nuclei (AGNs) can be divided into two major classes, namely radio loud and radio quiet AGNs. A small subset of the radio-loud AGNs is called blazars, which are beli…
A catalog of narrow-line Seyfert 1 galaxies in the southern hemisphere
S. Chen, M. Berton, G. La Mura +7
We present a new accurate sample of narrow-line Seyfert 1 galaxies (NLS1s) in the southern hemisphere from the Six-degree Field Galaxy Survey (6dFGS). Based on the optical spectral…
Models of Optical Emission Lines To Investigate Narrow-Line Seyfert 1 Galaxies in Spectroscopic Databases
G. La Mura, D. Bastieri, M. Berton +6
Thanks to the execution of extensive spectroscopic surveys that have covered large fractions of the sky down to magnitudes as faint as , it has been possible to ident…
VERITAS and Fermi-LAT observations of new HAWC sources
VERITAS Collaboration, A. U. Abeysekara, A. Archer +280
The HAWC (High Altitude Water Cherenkov) collaboration recently published their 2HWC catalog, listing 39 very high energy (VHE; >100~GeV) gamma-ray sources based on 507 days of obs…
