PeVatrons are cosmic accelerators capable of driving particles to petaelectronvolt (PeV) energies. Recently, microquasar jets have emerged as compelling Galactic PeVatron candidate…
Different Jet Dissipation Mechanisms Underlying the Variability in Blazars
Hong-bin Tan, Ruo-yu Liu
Blazars are among the most extreme classes of active galactic nuclei. They are powered by relativistic jets, but the way in which the jet energy is dissipated is still unclear. The…
Revisiting the XMM-Newton Observations of the Galactic Microquasar SS 433: Implications for the Origin of the Ultrahigh-Energy Emission Detected by LHAASO
Chao-Nan Tong, Hong-Bin Tan, Ruo-Yu Liu
Recently, the Large High Altitude Air Shower Observatory (LHAASO) detected ultrahigh-energy (UHE; photon energy E>100TeV) -ray emission toward SS 433, the microquasar embedded i…
A Model for Magnetic Reconnection as the Origin of TeV Outbursts from NGC 1275
Zhen-Jie Wang, Hong-Bin Tan, Ruo-Yu Liu
NGC 1275 showed two TeV -ray outbursts between November 2022 and January 2023, as detected by the Large High Altitude Air Shower Observatory (LHAASO). The source was also active…
The long-term accretion luminosity of V4641 Sgr through binary evolution simulations: implications for its ultrahigh-energy gamma-ray emission
Ruo-Yu Liu, Yong Shao, Yu-Dong Nie
Recent observations by LHAASO and HAWC have revealed extended ultrahigh-energy (UHE; TeV) gamma-ray emission associated with the black-hole X-ray binary (BHXRB) V4641 Sgr,…
A magnetised Galactic halo from inner Galaxy outflows
He-Shou Zhang, Gabriele Ponti, Ettore Carretti +12
Magnetic halos of galaxies are crucial for understanding galaxy evolution, galactic-scale outflows, and feedback from star formation activity. Identifying the magnetised halo of th…
Revisiting the TeV flare of PKS 2155-304 in 2006
Hong-Bin Tan, Ruo-Yu Liu, Markus Böttcher
Blazars, a subclass of active galactic nuclei (AGN), are known to be bright -ray sources, frequently exhibiting active (flaring) periods. The blazar PKS~2155-304 is a high synch…
A multi-zone view on the multi-wavelength emission of blazars
Ruo-Yu Liu, Rui Xue, Ze-Rui Wang +2
In this work, a time-dependent modeling is developed to study the emission properties of blazars in the low state. Motivated by various observations, we speculate and assume that n…
