New Hard X-Ray and Multiwavelength Study of the PeVatron Candidate PWN G0.9+0.1 in the Galactic Center Region

Giulia Brunelli, Kaya Mori, Jaegeun Park +12

We present a new X-ray study and multiwavelength spectral energy distribution (SED) modeling of the young pulsar wind nebula (PWN) powered by the energetic pulsar PSR J1747-2809, i…

Investigating the mysterious nature of 1LHAASO J1740+0948u through deep XMM-Newton observations

G. Brunelli, G. Ponti, H. Zhang +4

1LHAASO J1740+0948u is a very-high-energy (VHE) source reported by LHAASO, with no counterpart at other wavelengths. It is located at 0.2° from PSR J1740+1000, a radio and gamma-ra…

A new look at the extragalactic Very High Energy sky: searching for TeV-emitting candidates among the X-ray bright, non-Fermi detected blazar population

Stefano Marchesi, Antonio Iuliano, Elisa Prandini +8

We present the results of a multi-wavelength study of blazars selected from the 5th ROMABZCAT catalog. We selected from this sample a subsample of 2435 objects having at least one…

Discovery of a Radiation Component from the Vela Pulsar Reaching 20 Teraelectronvolts

The H. E. S. S. Collaboration, :, F. Aharonian +178

Gamma-ray observations have established energetic isolated pulsars as outstanding particle accelerators and antimatter factories in the Galaxy. There is, however, no consensus rega…
