Gamma-ray signature of superluminous supernovae: Fermi-LAT GeV detection of SN 2017egm and evidence of a central engine
F. Acero, A. Acharyya, A. Adelfio +116
Superluminous supernovae (SLSNe) are a rare class of transients with peak luminosities 10-100 times greater than those of standard core-collapse supernovae (SNe). The mechanisms po…
Geometry, Not Calorimetry, Drives the Radio/Infrared/Gamma-Ray Correlation
Troy A. Porter, Igor V. Moskalenko, Gudlaugur Johannesson
We investigate whether the observed radio-infrared--ray correlation in star-forming galaxies is a geometric effect rather than a signature of local cosmic-ray (CR) calorimetry.…
Simulating the Diffuse Neutrino Emission from the Milky Way with GALPROP
P. D. Marinos, T. A. Porter, G. P. Rowell +2
We use the GALPROP cosmic ray (CR) propagation framework to model the diffuse neutrino and gamma-ray emissions from the Galaxy. A collection of realistic bounding models are develo…
Characterizing Candidate Blazar Counterparts of the Ultra-High-Energy Event KM3-230213A
KM3NeT Collaboration, MessMapp Group, LAT Collaboration +13
High-energy astrophysical neutrinos serve as crucial messengers for understanding hadronic acceleration processes and identifying the origins of cosmic rays, with blazars among the…
Search for Extended GeV Sources in the Inner Galactic Plane
S. Abdollahi, F. Acero, A. Acharyya +108
The recent detection of extended -ray emission around middle-aged pulsars is interpreted as inverse-Compton scattering of ambient photons by electron-positron pairs escaping the…
On the Temporal Variability of the Galactic Multi-TeV Interstellar Emissions
P. D. Marinos, T. A. Porter, G. P. Rowell +2
We use the GALPROP cosmic ray (CR) framework to model the Galactic CR distributions and associated non-thermal diffuse emissions up to PeV energies. We consider ensembles of discre…
Very Local Impact on the Spectrum of Cosmic-Ray Nuclei below 100 TeV
Mikhail Malkov, Igor Moskalenko, Patrick Diamond +1
Recent measurements of primary and secondary CR spectra, their arrival directions, and our improved knowledge of the magnetic field geometry around the heliosphere allow us to set…
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…
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…
Fermi observations of the LIGO event GW170104
Melissa Pesce-Rollins, Nicola Omodei, Dan Kocevski +3
We present the \emph{Fermi} Gamma-ray Burst Monitor (GBM) and Large Area Telescope (LAT) observations of the LIGO binary black hole merger (BBH) event GW170104. No candidate electr…
Bayesian analysis of cosmic-ray propagation: evidence against homogeneous diffusion
G. Jóhannesson, R. Ruiz de Austri, A. C. Vincent +8
We present the results of the most complete ever scan of the parameter space for cosmic ray (CR) injection and propagation. We perform a Bayesian search of the main GALPROP paramet…
Deep morphological and spectral study of the SNR RCW 86 with Fermi-LAT
LAT Collaboration, G. Dubner, L. Duvidovich +4
RCW 86 is a young supernova remnant (SNR) showing a shell-type structure at several wavelengths and is thought to be an efficient cosmic-ray (CR) accelerator. Earlier \textit{Fermi…
