The 6th INTEGRAL workshop ``The Obscured Universe'' will take place at
the Space Research Institute (IKI),
Moscow, Russia on July 2-8, 2006 (the working days July 3-7).

The main goal of this workshop is to consider (via invited and contributed talks
and posters) the scientific problems in the field of high energy astrophysics
which are possible to solve using the
International
Gamma-Ray Astrophysics Laboratory INTEGRAL as well as to present and discuss
the scientific results already obtained by this observatory and its coordinated
observations with on-ground telescopes and other spacecrafts.

INTEGRAL is ESA's mission
(in collaboration with Russia and NASA) launched on October 17, 2002 and dedicated
to the fine gamma-ray spectroscopy and precise imaging of celestial sources in the
energy range 15 keV to 10 MeV with concurrent X-ray and optical source monitoring.
The observatory is in its extended mission phase.
The majority of observing time has been given to the scientific user community
at large through a single peer-review process.

Presentations of the workshop shall cover the following scientific topics:

• X-ray binaries (IGR sources, black-holes and neutron stars)
  
• Isolated neutron stars (gamma-ray pulsars, soft gamma-ray repeaters)
  
• Accretion and physics of compact objects, strange stars, microquasars
  
• Nucleosynthesis (SNe and SNRs, gamma-ray lines, diffuse emission)
  
• Surveys, extragalactic and unidentified sources, AGNs and blazars
  
• Super/massive black holes in AGNs, ellipticals, nucleus of the Galaxy
  
• INTEGRAL and dark matter, cosmic background
  
• Gamma-ray bursts
  
• Highlights from other high energy missions
  
• INTEGRAL status and instrument overviews (invited talks only)
  
• Science data processing and analysis (posters only)
  
• Future instruments and missions (posters only)
  

Oral reports should consider the subject in the broad context
with emphasis on physical processes and phenomena. The reviews
of both types (observational and theoretical) are welcome.

Deadline for abstract submission/pre-registration is March 1, 2006.

All contributions will be refereed by the Scientific Advisory Committee (SAC) and
published as one volume of the ESA-SP series.

Due to restrictions of the venue the amount of participants will be limited
to 250.
