Fermi-LAT gamma-ray study of the interstellar medium and cosmic rays in the Chamaeleon Molecular-Cloud Complex: A look at the dark gas as optically thick HI

Katsuhiro Hayashi, Tsunefumi Mizuno, Yasuo Fukui +6

We report a Fermi-LAT γ-ray analysis for the Chamaeleon molecular-cloud complex using a total column density (NH) model based on the dust optical depth at 353 GHz (τ353​) wit…

Radio and Gamma-Ray Constraints on the Emission Geometry and Birthplace of PSR J2043+2740

A. Noutsos, A. A. Abdo, M. Ackermann +146

We report on the first year of Fermi gamma-ray observations of pulsed high-energy emission from the old PSR J2043+2740. The study of the gamma-ray efficiency of such old pulsars gi…
