Fermi LAT detection of two high Galactic latitude gamma-ray sources, Fermi J1049.7+0435 and J1103.2+1145 [PDF]

arXiv, 2015
During a search for gamma-ray emission from NGC 3628 (Arp 317), two new unidentified gamma-ray sources, Fermi J1049.7+0435 and J1103.2+1145 have been discovered \cite{ATel}. The detections are made in data from the Large Area Telescope (LAT), on board the Fermi Gamma-ray Space Telescope, in the 100\,MeV to 300\,GeV band during the period between 2008 ...

The Contribution of Fermi Gamma-Ray Pulsars to the local Flux of Cosmic-Ray Electrons and Positrons

, 2010
We analyze the contribution of gamma-ray pulsars from the first Fermi-Large Area Telescope (LAT) catalogue to the local flux of cosmic-ray electrons and positrons (e+e-).

Highlights of GeV Gamma-Ray Astronomy [PDF]

, 2010
Because high-energy gamma rays are primarily produced by high-energy particle interactions, the gamma-ray survey of the sky by the Fermi Gamma-ray Space Telescope offers a view of sites of cosmic ray production and interactions. Gamma-ray bursts, pulsars,

A General Overview for Localizing Short Gamma-Ray Bursts with a CubeSat Mega-Constellation

Frontiers in Astronomy and Space Sciences, 2020
The gamma-ray burst monitor (GBM) on the Fermi Gamma-Ray Space Telescope, for the first time, detected a short gamma ray burst (SGRB) signal that accompanies a gravitational wave signal GW170817 in 2017.

Pulsar Timing with the Parkes Radio Telescope for the Fermi Mission [PDF]

, 2009
We report here on two years of timing of 168 pulsars using the Parkes radio telescope. The vast majority of these pulsars have spin-down luminosities in excess of 10^34 erg/s and are prime target candidates to be detected in gamma-rays by the Fermi Gamma-Ray Space Telescope.

Fermi Gamma-Ray Burst Monitor Science Highlights [PDF]

arXiv, 2012
Three years after the launch of the Fermi Gamma-ray Space Telescope, both of its scientific instruments are operating perfectly and continuing to make breakthroughs in astrophysics, particle physics, and atmospheric science. I report here on the highlights of the scientific program of the Fermi Gamma-ray Burst Monitor (GBM).

Fermi Large Area Telescope Observations of the Cosmic-Ray Induced gamma-ray Emission of the Earth's Atmosphere

, 2009
We report on measurements of the cosmic-ray induced gamma-ray emission of Earth's atmosphere by the Large Area Telescope onboard the Fermi Gamma-ray Space Telescope. The LAT has observed the Earth during its commissioning phase and with a dedicated Earth-

The Fermi Sky in a Multimessenger Context [PDF]

arXiv, 2017
The Fermi Gamma-Ray Space Telescope has been launched on June 11 2008. While it has fundamentally changed our understanding of the high-energy $\gamma$-ray sky, it is even more powerful in multiwavelength and multimessenger efforts. In this work I summarize results from Fermi-LAT in the multimessenger context, pertaining to high-energy neutrinos.
