Active galactic nuclei (AGN) are energetic astrophysical sources powered by accretion onto
supermassive black holes in galaxies, and present unique observational signatures that …

The extragalactic background light (EBL) is one of the fundamental observational quantities
in cosmology. All energy releases from resolved and unresolved extragalactic sources, and …

Thanks to its broad energy range, excellent sensitivity, and all-sky monitoring capabilities,
the Fermi Gamma-ray Space Telescope Large Area Telescope (LAT) has revolutionized our …

Since its launch in 2008, the Fermi Large Area Telescope (LAT; Atwood et al. 2009) has
enabled the discovery of new classes of gamma-ray emitters and the detection of much …

We present a catalog of sources detected above 10 GeV by the Fermi Large Area Telescope
(LAT) in the first 7 years of data using the Pass 8 event-level analysis. This is the Third …

The initial discovery of astrophysical neutrino flux around PeV energies (Aartsen et al.
2013a) a few years ago marked the beginning of high-energy neutrino astronomy. Since …

We describe new implementations of leptonic and hadronic models for the broadband
emission from relativistic jets in active galactic nuclei in a temporary steady state. For the …

The dwarf spheroidal satellite galaxies of the Milky Way are some of the most dark-matter-
dominated objects known. Due to their proximity, high dark matter content, and lack of …

The lower-energy peak of the spectral energy distribution of blazars has commonly been
ascribed to synchrotron radiation from relativistic particles in the jets. Despite the consensus …

Magnetic reconnection is thought to be the driver for many explosive phenomena in the
universe. The energy release and particle acceleration during reconnection have been …
