I am pleased to announce the 6th Workshop on
Science with the New Generation of High Energy Gamma Ray Experiments [Scineghe08]
that will be held on October 8-10, 2008 in Abano Terme, Padova, Italy.
This year the focus will be on bridging the gap between GeV and TeV.
In fact, between the higher energies accessible to satellites and the energy threshold of ground based gamma-ray telescopes, a sizeable region of the electromagnetic spectrum, more than a decade wide, remains unexplored. In this interval, several fundamental problems concerning Astrophysics, Cosmology and Fundamental Physics could find their answers from a thorough astronomical observation. Cherenkov detectors already caught a few glimpses in this region: the full new wealth of sources in HESS' galactic scan or the discovery by MAGIC of new classes of extragalactic VHE emitters like Flat-Spectrum Radio Quasars (FSRQ) or the Low-frequency BL Lac's type (LBL). However, the gap will now be covered by the observations of AGILE and GLAST satellites, sensitive in this region where most of the source cutoffs lie.
This workshop, shortly after GLAST's launch, is one of the first occasions to understand the new opportunities opened by the satellites in orbit, and it is devoted to the sources that will profit more from broad-band (GeV-TeV) observations, possibly giving answers to many astrophysical issues.
Among these there are galactic sources, like pulsars, where a precise measurement of the energy cutoff of the pulsed spectra can discriminate among many competitive acceleration scenarioes. There are also extragalactic sources like active nuclei, where broad-band measurements effectively probe the inner structure of the gravitational engine, or Gamma Ray Bursts (GRBs) where observations by the LAT instrument (on-board the GLAST observatory) may trigger important follow-up with Cherenkov telescopes.
Moreover, the observation of sources located at medium redshift (0.2 < z < 0.5 for Cherenkov and z ~ 1 with GLAST) heavily constrains the EBL, either requiring to refine the evaluation of EBL's components or even to invoke new physics.
Scineghe08 will be an ideal occasion to discuss topics as:
Topic 1: Non-thermal Galactic Sources
- Supernova Remnants
- Pulsars & plerions
- Binary systems and other compact galactic objects
- Diffuse galactic emission
Topic 2: Extragalactic Sources
- High-frequency peaked BL Lac (HBL)
- Active galaxies and blazars
- Gamma Ray Bursts
- AGN fast variability
- Correlations of gamma-ray and optical activity
- AGN & Extragalactic Background Light (EBL)
Topic 3: Dark Matter & exotic physics
Topic 4: What next? The future of gamma-ray astronomy
The program includes sessions by invited speakers summarising the state of the art in the fields previously highlighted, as well as the opportunity to present your own results.
A second circular will be sent around shortly following this one with registration and accommodation information.
