V Congresso Nazionale GRB
12-15 settembre 2022
Il congresso, nel venticinquennale della scoperta degli afterglow da parte di BeppoSAX, vuole essere un'occasione per discutere i recenti sviluppi nel campo dei GRB, soprattutto a seguito della scoperta di emissione ad altissime energie e della connessione degli short GRB con le sorgenti di onde gravitazionali, in vista delle future missioni dedicate ai GRB.
Saranno previste sessioni dedicate a discussioni su questi hot topics:
- Emissione al GeV dei GRB prompt o afterglow?
- Qual è l'origine della Plateau emission?
- E' meglio un sistema di detection Distribuito o Concentrato (sistema di satelliti o un satellite solo?) per il prompt?
- Quali strumenti sono essenziali per le altre fasi dei GRB?
- Quale l'origine della relazione di Amati?
- Motore centrale: magnetar o buco nero?
- Il getto: strutturato o no?
- Il getto: magnetico o cinetico?
- Quale l'origine dell'emissione a basse energie del prompt? Black body o Sincrotrone?
- Che relazione tra i GRB e altri fenomeni transienti?
- Emissione al TeV: SSC o sincrotrone?
Programma scientifico
Il congresso accoglierà inoltre al solito contributi teorici ed osservativi su temi tipici del settore legato ai GRB:
Dissecting the interstellar medium of a z=6.3 galaxy. X-shooter spectroscopy and HST imaging of the afterglow and environment of the Swift GRB 210905A.
Time Evolving Photoionisation Device (TEPID): a new code for time evolving photoionisation and spectral fitting.
Il 2022 e’ anche il 25ennale della prima osservazione di un afterglow di GRB fatta con BeppoSAX prima nei raggi X e poi con i telescopi di La Palma, e pure di Campo Imperatore in ottico. Questo ha portato alla localizzazione accurata delle galassie ospiti e alla conseguente osservazione spettroscopica che ha determinato che le distanze dei GRB erano cosmologiche.
Bibliografia: https://www.nature.com/articles/42885CCD images of the field of GRB970228 taken at the 0.60 m Schmidt telescope at Campo Imperatore.
The numbers indicate the reference stars, used to set the photometry zero point.
The centers of the circles indicate the location of the Optical Transient (labelled OT) and of the KM star (labelled S).
Each image covers a field of ≈ 2.8 × 1.9 arcmin2 . North and East are top and left, respectively.
Bibliografia: https://www.nature.com/articles/386686a0V-band images of a 1.5' x 1.5' region of the sky containing the position of the opticatl transient. The left image was obtained with the WHT on 1997 28th of Febrauary, UT 23h 48min, the right image with the INT on March, UT 20h 42min.
The optical transient is indicated by 'OT'. The 'M' dwarf, separeted from the optical transient by 2.9", is also indicated. Bibliografia: https://arxiv.org/pdf/astro-ph/9709105.pdf
