AGILE detection of transient γ-ray emission from the region of the supergiant fast X-ray transient source IGR J17354-3255
Andrea Bulgarelli, Gabriele Panebianco, Vito Sguera +16
Context. On April 14, 2009, the AGILE satellite detected a γ-ray flare from an unknown transient source. Subsequent X-ray follow-up observations with Swift and INTEGRAL identified…
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-r…
Low-frequency spectra of neutron star + OB supergiant binaries: Does wind density drive persistent and flaring modes of accretion?
J. van den Eijnden, L. Sidoli, M. DÃaz Trigo +10
Neutron star high-mass X-ray binaries are well-studied in wavebands between the infrared and hard X-rays. Their low-frequency millimeter and radio properties, on the other hand, re…
Prospects for dark matter observations in dwarf spheroidal galaxies with the Cherenkov Telescope Array Observatory
K. Abe, S. Abe, J. Abhir +491
The dwarf spheroidal galaxies (dSphs) orbiting the Milky Way are widely regarded as systems supported by velocity dispersion against self-gravity, and as prime targets for the sear…
Recasting the nature of INTEGRAL hard X-ray transients previously classified as active galactic nuclei
V. Sguera, L. Sidoli
We present new broad-band X-ray results aimed at the identification and characterization of four poorly studied hard X-ray transients discovered by INTEGRAL: IGR J16426+6536, IGR J…
