Upper Bound on the First Star Formation History
Yoshiyuki Inoue, Yasuyuki T. Tanaka, Grzegorz M. Madejski +1
Our understanding of the nature of the extragalactic background light (EBL) has improved with the recent development of gamma-ray observation techniques. An open subject in the con…
Fermi-LAT Observations of the Gamma-ray Burst GRB 130427A
LAT collaboration, GBM collaboration
The observations of the exceptionally bright gamma-ray burst (GRB) 130427A by the Large Area Telescope aboard the Fermi Gamma-ray Space Telescope provide constraints on the nature…
First Results from NuSTAR Observations of Mkn 421
M. Baloković, M. Ajello, R. D. Blandford +34
Mkn 421 is a nearby active galactic nucleus dominated at all wavelengths by a very broad non-thermal continuum thought to arise from a relativistic jet seen at a small angle to the…
Suzaku observations of the diffuse x-ray emission across the fermi bubbles' edges
J. Kataoka, M. Tahara, T. Totani +10
We present Suzaku X-ray observations along two edge regions of the Fermi Bubbles, with eight ~20 ksec pointings across the northern part of the North Polar Spur (NPS) surrounding t…
Fermi Large Area Telescope Detection of Two Very-High-Energy (E>100 GeV) Gamma-ray Photons from the z = 1.1 Blazar PKS 0426-380
Y. T. Tanaka, C. C. Cheung, Y. Inoue +10
We report the Fermi Large Area Telescope (LAT) detection of two very-high-energy (VHE, E>100 GeV) gamma-ray photons from the directional vicinity of the distant (redshift, z = 1.1)…
Probing the Cosmic X-ray and MeV Gamma-ray Background Radiation through the Anisotropy
Yoshiyuki Inoue, Kohta Murase, Grzegorz M. Madejski +1
While the cosmic soft X-ray background is very likely to originate from individual Seyfert galaxies, the origin of the cosmic hard X-ray and MeV gamma-ray background is not fully u…
Prospects for future very high-energy gamma-ray sky survey: impact of secondary gamma rays
Yoshiyuki Inoue, Oleg E. Kalashev, Alexander Kusenko
Very high-energy gamma-ray measurements of distant blazars can be well explained by secondary gamma rays emitted by cascades induced by ultra-high-energy cosmic rays. The secondary…

The CTA Consortium, :, O. Abril +1102
Compilation of CTA contributions to the proceedings of the 33rd International Cosmic Ray Conference (ICRC2013), which took place in 2-9 July, 2013, in Rio de Janeiro, Brazil
The Cherenkov Telescope Array Large Size Telescope
G. Ambrosi, Y. Awane, H. Baba +129
The two arrays of the Very High Energy gamma-ray observatory Cherenkov Telescope Array (CTA) will include four Large Size Telescopes (LSTs) each with a 23 m diameter dish and 28 m…
Constraints on the Galactic Population of TEV Pulsar Wind Nebulae Using Fermi Large Area Telescope Observations
F. Acero, M. Ackermann, M. Ajello +155
Pulsar wind nebulae (PWNe) have been established as the most populous class of TeV gamma-ray emitters. Since launch, the Fermi Large Area Telescope (LAT)identified five high-energy…
X-ray and Radio Follow-up Observations of High-Redshift Blazar Candidates in the Fermi-LAT Unassociated Source Population
Y. Takahashi, J. Kataoka, K. Niinuma +6
We report on the results of X-ray and radio follow-up observations of two GeV gamma-ray sources 2FGL J0923.5+1508 and 2FGL J1502.1+5548, selected as candidates for high-redshift bl…
Search for Gamma-ray Spectral Lines with the Fermi Large Area Telescope and Dark Matter Implications
LAT Collaboration
Weakly Interacting Massive Particles (WIMPs) are a theoretical class of particles that are excellent dark matter candidates. WIMP annihilation or decay may produce essentially mono…
The Fermi All-sky Variability Analysis: A list of flaring gamma-ray sources and the search for transients in our Galaxy
