Searching for the most distant blazars with the Fermi Gamma-ray Space Telescope [PDF]

open access: hybridProceedings of 25th Texas Symposium on Relativistic Astrophysics — PoS(Texas 2010), 2011
We investigate the prospects for discovering blazars at very high-redshifts (z>3-6) with the Fermi Gamma-Ray Space Telescope (Fermi), employing a model for the evolving gamma-ray luminosity function (GLF) of the blazar population. Our previous GLF model is used as a basis, which features luminosity-dependent density evolution implied from X-ray data

Pulsar Observations with the Fermi Gamma-ray Space Telescope

open access: green, 2009
The Large Area Telescope (LAT) on Fermi, launched on 2008 June 11, is a space telescope to explore the high energy gamma-ray universe. The instrument covers the energy range from 20 MeV to 300 GeV with greatly improved sensitivity and ability to localize gamma-ray point sources.

Identification of Gamma-Ray Point Sources in Fermi-LAT Data with Minimum Spanning Tree Algorithm [PDF]

open access: yesIranian Journal of Astronomy and Astrophysics, 2023
Gamma rays are the most energetic photons in the electromagnetic spectrum, detected with ground-based and space-based detectors in different energy ranges from sources in our galaxy and beyond.

Subphotospheric dissipation in gamma-ray bursts observed by the Fermi Gamma-ray Space Telescope

open access: green, 2016
Gamma-ray bursts (GRBs) are the brightest events in the Universe, for a short time outshining the rest of the Universe combined, as they explode with isotropic equivalent luminosities up to $10^{54}$ erg s$^{-1}$. These events are believed to be connected to supernovae and to binary compact object mergers, such as binary neutron stars or neutron star --

GRAINE project: precise gamma-ray observations with balloon-borne emulsion telescope [PDF]

open access: yesEPJ Web of Conferences, 2019
Observation of cosmic gamma rays is important in the understanding of high-energy objects or phenomena in the universe. Since 2008, the Large Area Telescope onboard the Fermi Gamma-ray Space Telescope (Fermi-LAT) has surveyed the sub-GeV/GeV gamma-ray ...
