Using gamma-rays to probe the clumped structure of stellar winds
G. E. Romero, S. P. Owocki, A. T. Araudo +2
Gamma-rays can be produced by the interaction of a relativistic jet and the matter of the stellar wind in the subclass of massive X-ray binaries known as "microquasars". The relati…
Extreme photo-polarimetric behaviour of the blazar AO 0235+164
Sergio A. Cellone, Gustavo E. Romero, Jorge A. Combi +1
We present optical photo-polarimetric observations with high temporal resolution of the blazar AO 0235+164. Our data, the first to test the photo-polarimetric behaviour of this obj…
Gamma-ray absorption in the microquasar SS433
Matias M. Reynoso, Hugo R. Christiansen, Gustavo E. Romero
We discuss the gamma-ray absorption in the inner region of the microquasar SS433. Our investigation includes several contributions to the opacity of this system. They result from t…
Jet interactions in massive X-ray binaries
Gustavo E. Romero
Massive X-ray binaries are formed by a compact object that accretes matter from the stellar wind of an early-type donor star. In some of these systems, called microquasars, relativ…
Very high energy gamma-ray emission from X-ray transients during major outbursts
M. Orellana, G. E. Romero, L. J. Pellizza +1
Context: Some high mass X-ray binaries (HMXB) have been recently confirmed as gamma-ray sources by ground based Cherenkov telescopes. In this work, we discuss the gamma-ray emissio…
