Estimating Galactic gas content using different tracers: Compatibility of results, dark gas, and unidentified TeV sources
Torres, Diego F.; de Oña Wilhelmi, Emma; Natale, Giovanni +1 more
A large fraction of Galactic very-high energy (VHE; E ≳ 100 GeV) γ-ray sources is cataloged as unidentified. In this work we explore the possibility that these unidentified sources are located in environment particularly rich in material content unaccounted by traditional tracers. In a scenario where the VHE emission is due to the interaction of t…
Time-dependent modeling of TeV-detected, young pulsar wind nebulae
Torres, D. F.; de Oña Wilhelmi, E.; Cillis, A. +1 more
The increasing sensitivity of instruments at X-ray and TeV energies has revealed a large number of nebulae associated with bright pulsars. Despite this large data set, the observed pulsar wind nebulae (PWNe) do not show a uniform behavior and the main parameters driving features like luminosity, magnetization, and others are still not fully unders…
Searching for small-scale diffuse emission around SGR 1806-20
Tiengo, A.; Mereghetti, S.; Stella, L. +6 more
Diffuse radio emission was detected around the soft gamma-ray repeater SGR 1806-20 after its 2004 powerful giant flare. We study the possible extended X-ray emission at small scales around SGR 1806-20, in two observations by the High Resolution Camera Spectrometer (HRC-S) on board of the Chandra X-ray Observatory: in 2005, 115 days after the giant…
