GRB 100614A and GRB 100615A: two extremely dark GRBs

V. D'Elia, G. Stratta

Dark gamma-ray bursts (GRBs) are sources with a low optical-to-X-ray flux ratio. Proposed explanations for this darkness are: i) the GRB is at high redshift ii) dust in the GRB hos…

Observation of the Cosmic Ray Moon shadowing effect with ARGO-YBJ

YBJ Collaboration

Cosmic rays are hampered by the Moon and a deficit in its direction is expected (the so-called \emph{Moon shadow}). The Moon shadow is an important tool to determine the performanc…

XMM-Newton discovery of a possible cyclotron emission feature from the SFXT IGR J18483-0311

V. Sguera, L. Sidoli, A. Bazzano +2

We report the results from an archival XMM-Newton observation of the Supergiant Fast X-ray Transient (SFXT) IGR J18483-0311 during its apastron passage. The measured 0.5--10 keV lu…

Supergiant Fast X-ray Transients

Lara Sidoli

The phenomenology of a subclass of High Mass X-ray Binaries hosting a blue supergiant companion, the so-called Supergiant Fast X-ray Transients (SFXTs), is reviewed. Their number i…

The Swift Supergiant Fast X-ray Transients Project: recent results

P. Romano, S. Vercellone, V. La Parola +8

We present an overview of our Supergiant Fast X-ray Transients (SFXT) project, that started in 2007, by highlighting the unique observational contribution Swift is giving to this e…
