Unresolved nature source TeV J2032+4130

Cygnus Region contains many objects that are bright in all wavelengths, including one of the most powerful active star formation regions: Cyg OB2, pulsars, and supernova remnants. Some of the sources have been detected at high and very high energies. One of them was discovered due to the proximity to well-known microquasar Cyg X-3 is object TeV J2032+4130. This object is still of unresolved nature and is being intensively studied in the different energy ranges. The numerous X-ray point sources and diffuse X-ray emission regions were found within the TeV J2032+4130 region by Chandra and Suzaku. Intensities detected in X-rays from these regions may favor a scenario with the dominantly nucleonic, not electronic origin of TeV emission. The results of the twenty-year observation of TeV J2032+4130 object by the SHALON experiment are presented. The collected experimental data on fluxes, spectrum shape, and morphology of TeV J2032+413 can help determine an object type and shed light on the source nature

ALICE A Large Ion Collider Experiment

POLAR-2 is a follow-up GRB mission of POLAR, which has observed low levels of polarization degree and a temporal evolution of the polarization angle, indicating that time resolved studies of $\gamma$ photons polarization are required to constrain theoretical emission models of GRB’s. POLAR-2 detector aim to put in space a detector with one order of magnitude sensitivity improvement versus POLAR. POLAR-2 will be the most sensitive GRB detector covering half of the sky. The instrument, proposed by an international collaboration, was selected to be launched in 2024 to the China Space Station and operate for at least 2 years. POLAR-2 will use same plastic bar concept then POLAR but will be readout by SiPMT. The payload will also feature a spectrometer. The instrument is foreseen to perform detailed polarization measurements of at least 100 GRBs
