New INTEGRAL sources and TeV emission

Abstract

INTEGRAL is operational since more than three years and producing high quality data that allows to detect fainter new hard X-ray sources. The new sources, identified until now, are mostly active galactic nuclei and absorbed or transient high mass X-ray binaries. TeV emission could be expected from the new high mass X-ray binaries accreting dense clumps of stellar wind. INTEGRAL sources with TeV counterparts are discussed.

High-mass X-ray binaries in the Milky Way

“…Since 2005, SFTXs have been monitored regularly in the X-rays and a relatively large effort was devoted to perform observations of these sources in different energy domains, spanning from the far IR to γ-rays (Walter, 2007) and up to the very high energies (∼GeV; Sguera et al, 2009Sguera et al, , 2011. It was soon understood that all SFXT systems were hosting a compact object accreting from the wind of a massive companion, typically a super-giant O-B star (Tomsick et al, 2006aChaty et al, 2008;Masetti et al, 2008b;Negueruela et al, 2008b;Tomsick, 2009;Tomsick et al, 2009b;Bodaghee et al, 2012a).…”
