Discovery of EP J175257.3-351923 as a Candidate Black Hole Low-Mass X-ray Binary
G. L. Huang, Q. C. Zhao, L. Tao +30
We report the discovery of a new X-ray transient, EP J175257.3-351923 (EP250916a), by the Einstein Probe (EP) near the Galactic plane. The outburst lasted for at least 250\,days, r…
Testing Heavy Dark Matter Decay as the Origin of KM3-230213A
KM3NeT Collaboration, O. Adriani, J. A. Aguilar +287
This work explores the hypothesis that the ultra-high-energy neutrino event KM3-230213A originates from the decay of a heavy dark matter particle with a mass above PeV scale. The a…
Constraining gamma-ray burst parameters with the first ultra-high energy neutrino event KM3-230213A
KM3NeT Collaboration, O. Adriani, A. Albert +278
Context: The detection of the highest energy neutrino observed to date by KM3NeT, with an estimated energy of 220 PeV, opens up new possibilities for the study and identification o…
3C403: a candidate neutrino-emitting radio galaxy
Gabriele Bruni, Loredana Bassani, Sergio Alves Garre +12
3C403 is a well-known FRII radio galaxy with jets extending up to kiloparsec scales. We report its identification as the second most significant candidate among more than 150 sourc…
Multi-wavelength Study of A Superflare on RS CVn-type Star HD22468 Triggered at Hard X-ray by SVOM
J. Wang, W. J. Xie, F. Cangemi +36
Detection of stellar flares at hard X-ray is still rare at the current stage. A transient was recently detected by the hard X-ray camera, ECLAIRs onboard the SVOM mission at 11:39:…
SVOM discovery of a strong X-ray outburst of the blazar 1ES~1959+650 and multi-wavelength follow-up with the Neil Gehrels Swift observatory
A. Foisseau, A. Coleiro, S. Komossa +37
On December 6, 2024, 1ES 1959+650, one of the X-ray brightest blazars known, underwent a high-amplitude X-ray outburst detected by SVOM, the first such discovery with this mission.…
