Aims: We provide new insights into the gamma-ray emission from HESS J1912+101, a TeV supernova remnant candidate probably associated with the radio pulsar PSR J1913+1011. Methods: We obtained new observations at 1.5 GHz using the VLA in the D configu

Aims. We provide new insights into the nature of HESS J1857+026, a very-high-energy {\gamma}-ray source whose complex morphology in the TeV band was attributed to the superposition of two distinct sources. Methods. We performed radio continuum observ

AIMS: HESS J1844-030 is a newly confirmed TeV source in the direction of the X-ray pulsar wind nebula (PWN) candidate G29.4+0.1 and the complex radio source G29.37+0.1, which is likely formed by the superposition of a background radio galaxy and a Ga

Aims: We study the supernova remnant G20.0-0.2 and its surroundings in order to look for the high energy counterpart of the radio nebula and to find evidence of interaction between the shock front and the interstellar medium. Methods: We used Chandra

En esta Tesis, se estudian desde el punto de vista observacional algunos de losefectos que producen sobre el medio interestelar las ondas de choque asociadas conestrellas de gran masa en diferentes etapas de su vida. Se investiga la interacciónde re
