Localizing the -ray emitting region in the blazar TXS 2013+370
E. Traianou, T. P. Krichbaum, B. Boccardi +9
The -ray production mechanism and its localization in blazars are still a matter of debate. The main goal of this paper is to constrain the location of the high-energy emission…
Bright gamma-ray flares observed in GRB131108A
Donggeun Tak, Z. Lucas Uhm, Bing Zhang
GRB 131108A is a bright long Gamma-Ray Burst (GRB) detected by the Large Area Telescope and the Gamma-ray Burst Monitor on board the Fermi Gamma-ray Space Telescope. Dedicated temp…
Exploring the Morphology and Origins of the 4C 38.41 Jet
Juan Carlos Algaba, Bindu Rani, Sang-Sung Lee +3
We study the properties of the innermost jet of the flat spectrum radio quasar 1633+382 (4C~38.41) based on VLBI data from the radio monitoring observations of the Boston Universit…
Fermi and Swift Observations of GRB 190114C: Tracing the Evolution of High-Energy Emission from Prompt to Afterglow
M. Ajello, M. Arimoto, M. Axelsson +147
We report on the observations of gamma-ray burst (GRB) 190114C by the Fermi Gamma-ray Space Telescope and the Neil Gehrels Swift Observatory. The early-time observations reveal mul…
All-sky Medium Energy Gamma-ray Observatory: Exploring the Extreme Multimessenger Universe
Julie McEnery, Juan Abel Barrio, Ivan Agudo +182
The All-sky Medium Energy Gamma-ray Observatory (AMEGO) is a probe class mission concept that will provide essential contributions to multimessenger astrophysics in the late 2020s…
Origin and Evolution of the Multi-band Variability in the Flat Spectrum Radio Source 4C 38.41
Juan Carlos Algaba, Sang Sung Lee, Bindu Rani +13
The flat spectrum radio quasar 4C 38.41 showed a significant increase of its radio flux density during the period 2012 March - 2015 August which correlates with gamma-ray flaring a…
Prospects for AGN Studies at Hard X-ray through MeV Energies
Eileen Meyer, Justin Finke, George Younes +7
This White Paper explores advances in the study of Active Galaxies which will be enabled by new observing capabilities at MeV energies (hard X-rays to gamma-rays; 0.1-1000 MeV), wi…
Neutrinos, Cosmic Rays and the MeV Band
R. Ojha, H. Zhang, M. Kadler +23
The possible association of the blazar TXS 0506+056 with a high-energy neutrino detected by IceCube holds the tantalizing potential to answer three astrophysical questions: 1. Wher…
Energetic Particles of Cosmic Accelerators II: Active Galactic Nuclei and Gamma-ray Bursts
Tonia M. Venters, Sylvain Guiriec, Amy Y. Lien +26
The high-energy universe has revealed that energetic particles are ubiquitous in the cosmos and play a vital role in the cultivation of cosmic environments on all scales. Though th…
Multi-Physics of AGN Jets in the Multi-Messenger Era
B. Rani, M. Petropoulou, H. Zhang +20
Active galactic nuclei (AGN) with relativistic jets, powered by gas accretion onto their central supermassive black hole (SMBH), are unique laboratories for studying the physics of…
Opportunities for Multimessenger Astronomy in the 2020s
E. Burns, A. Tohuvavohu, J. M. Bellovary +22
Electromagnetic observations of the sky have been the basis for our study of the Universe for millennia, cosmic ray studies are now entering their second century, the first neutrin…
MAGIC and Fermi-LAT gamma-ray results on unassociated HAWC sources
M. L. Ahnen, S. Ansoldi, L. A. Antonelli +336
The HAWC Collaboration released the 2HWC catalog of TeV sources, in which 19 show no association with any known high-energy (HE; E > 10 GeV) or very-high-energy (VHE; E > 300 GeV)…
