The impact of Solar magnetic field configurations on the production of gamma rays at the Solar disk
Julien Dörner, Frederic Effenberger, Horst Fichtner +4
The Sun produces a steady signal of high-energy gamma rays through interactions of Galactic cosmic rays (GCRs) with its atmosphere. Observations with Fermi-LAT and HAWC have reveal…
GRB Redshift Estimation using Machine Learning and the Associated Web-App
Aditya Narendra, Maria Dainotti, Milind Sarkar +7
Context. Gamma-ray bursts (GRBs), observed at redshifts as high as 9.4, could serve as valuable probes for investigating the distant Universe. However, this necessitates an increas…
Gamma-ray Bursts as Distance Indicators by a Statistical Learning Approach
Maria Giovanna Dainotti, Aditya Narendra, Agnieszka Pollo +6
Gamma-ray bursts (GRBs) can be probes of the early universe, but currently, only 26% of GRBs observed by the Neil Gehrels Swift Observatory GRBs have known redshifts () due to o…
On the Existence of the Plateau Emission in High-Energy Gamma-Ray Burst LightCurves observed byFermi-LAT
Maria Giovanna Dainotti, Nicola Omodei, Gokul . P. Srinivasaragavan +10
The Large Area Telescope (LAT) on board the \Fermi Gamma-ray Space Telescope (\Fermi) shows long-lasting high-energy emission in many gamma-ray bursts (GRBs), similar to X-ray afte…
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…
Luminosity--time and luminosity--luminosity correlations for GRB prompt and afterglow plateau emissions
M. G. Dainotti, V. Petrosian, R. Willingale +3
We present an analysis of 123 Gamma-ray bursts (GRBs) with known redshifts possessing an afterglow plateau phase. We reveal that correlation between the X-ray luminos…
The Spectrum and Morphology of the Fermi Bubbles
LAT Collaboration
The Fermi bubbles are two large structures in the gamma-ray sky extending to above and below the Galactic center. We analyze 50 months of Fermi Large Area Telescope data…
Gamma-ray Luminosity and Photon Index Evolution of FSRQ Blazars and Contribution to the Gamma-ray Background
J. Singal, A. Ko, V. Petrosian
We present the redshift evolutions and distributions of the gamma-ray luminosity and photon spectral index of flat spectrum radio quasar (FSRQ) type blazars, using non-parametric m…
Identification and properties of the photospheric emission in GRB090902B
F. Ryde, M. Axelsson, B. B. Zhang +19
The Fermi Gamma-ray Space Telescope observed the bright and long GRB090902B, lying at a redshift of z = 1.822. Together the Large Area Telescope (LAT) and the Gamma-ray Burst Monit…
