High-energy gamma-rays from stellar associations

Diego F. Torres, Eva Domingo-Santamaria, Gustavo E. Romero

It is proposed that TeV gamma-rays and neutrinos can be produced by cosmic rays (CRs) through hadronic interactions in the innermost parts of the winds of massive O and B stars. Co…

Hadronic gamma-ray emission from windy microquasars

Gustavo E. Romero, Diego F. Torres, M. M. Kaufman Bernado +1

The jets of microquasars with high-mass stellar companions are exposed to the dense matter field of the stellar wind. We present estimates of the gamma-ray emission expected from t…

Testing the binary black hole paradigm through the Fe Kalpha line profile: application to 3C 273

Diego F. Torres, Gustavo E. Romero, Xavier Barcons +1

We propose the study of long-term variations in the Fe Kalpha line profile as a discriminator for binary black hole (BH) systems. The existence of a binary BH in the center of an a…

On the cross correlation between the arrival direction of ultra-high energy cosmic rays, BL Lacertae, and EGRET detections: A new way to identify EGRET sources?

Diego F. Torres, Stephen Reucroft, Olaf Reimer +1

With the aim of testing recent claims for a particularly strong correlation between ultra-high energy cosmic rays (UHECRs), observed with the AGASA and the Yakutsk experiments, and…

Gamma-ray sources at high latitudes (Extragalactic gamma-ray sources)

Diego F. Torres

This Chapter provides a review of -ray sources lying at high Galactic latitudes. Their statistical properties and variability status, as well as studies involving cross correlat…

Signatures of hadronic cosmic rays in starbursts? High-energy photons and neutrinos from NGC253

Gustavo E. Romero, Diego F. Torres

We show that it appears possible for starburst galaxies, like the nearby NGC 253, recently identified as a TeV source by the CANGAROO collaboration, to emit a significant amount of…
