Alessandro Carosi (Istituto Nazionale di Astrofisica (INAF))

We are pleased to announce the workshop “AVENGe - Advances in Very-High Energy Astrophysics with Next-Generation Cherenkov Telescopes", that will be held at Sala Conferenze Cappuccini in Rome (Italy) on May 29-31, 2023. 

The Workshop aims to build or improve the synergies between the different science groups belonging to INAF, INFN and Universities in view of the preparation of the Observational Key Science Projects for the CTA. To this end, both summary and contributed talks covering the main hot topics in VHE astrophysics are foressen as well as dedicated discussion at the end of each presentation block.

The main topics covered by the workshop are:

• Galactic and extragalactic extreme cosmic accelerators 
• VHE transients follow-up from GRBs to GW and Neutrino counterparts
• Pevatrons and their origin
• Dark Matter and Fundamental Physics with VHE gamma ray
• New ideas for future gamma-rays facilities and multi-messenger synergies
• The role and contribution of Italian community to CTA/CTA+

 

No registration fee is required.

A meeting dinner is foreseen for May the 30th (to be paid individually by participants)

Registrations are opened until 2023, May 25

 

See you in Roma!

15:00 Galactic PeVatron candidates in the LHAASO J1956+2845 sky region

In recent years the number of known sources emitting in the TeV-PeV regime has increased significantly thanks to facilities like LHAASO and HAWC. The more natural candidates, for energetic and ambient properties, are pulsars and their environment.

However, due to the limited angular resolution of the current instruments, many of the observed sources have more than one lower-energy counterpart. The identification and the classification of these sources is one of the primary goals of future facilities as CTAO, thanks to the designed sensitivity and angular resolution above 1 TeV.

In this talk I will present the sky region containing LHAASO J1956+2845, a case study to test the CTAO performances. This region extends for about 2 degrees and contains three HAWC sources, two of which are spatially coincident with LHAASO J1956+2845. Three middle-aged pulsars and three SNR/PWN systems are located in the field, but the associations are yet to be done, and it is not clear yet which of them is the principal contributor to the ~100 TeV emission.

10:40 Blazar monitoring by the Whole Earth Blazar Telescope (WEBT) Collaboration

Born in 1997 to provide an optical follow-up of gamma-loud blazars observed by the Compton Gamma Ray Observatory, the Whole Earth Blazar Telescope (WEBT) is a large collaboration including several tens of astronomers around the northern hemisphere who monitor blazars mainly in the optical (including polarimetry), but also in the radio and near-infrared bands. Since 2000 the Collaboration has been led by Italian researchers from the INAF- Osservatorio Astrofisico di Torino and has actively collaborated with other teams, in particular the AGILE, Fermi, and MAGIC ones. The strength of the WEBT is the high temporal resolution of the light curves, which can be obtained thanks to the distribution in longitude of its members. This allows us to study the details of the blazar multiwavelength behaviour, and to propose models for its interpretation. We are looking forward to a fruitful collaboration with the VHE community in the era of the new-generation Cherenkov telescopes.
