Constraining baryon loading efficiency of AGNs with diffuse neutrino flux from galaxy clusters
Xin-Yue Shi, Ruo-Yu Liu, Chong Ge +1
The active galactic nuclei (AGNs) are widely believed to be one of the promising acceleration sites of ultrahigh-energy cosmic rays (CRs). Essentially, AGNs are powered by the grav…
Revisiting the Chandra Observation on the Region of PSR J1809-1917: Indication of an X-ray Halo and Implication for the Origin of HESS J1809-193
Chao-Ming Li, Chong Ge, Ruo-Yu Liu
HESS J1809-193 is an extended TeV -ray source and the origin of its -ray emission remains ambiguous. Pulsar wind nebula (PWN) of PSR J1809-1917 laying inside the extended …
Revealing a peculiar supernova remnant G106.3+2.7 as a petaelectronvolt proton accelerator with X-ray observations
Chong Ge, Ruo-Yu Liu, Shu Niu +2
Supernova remnants (SNRs) have long been considered as one of the most promising sources of Galactic cosmic rays. In the SNR paradigm, petaelectronvolt (PeV) proton acceleration ma…
AGN feedback in the FR II galaxy 3C 220.1
Wenhao Liu, Ming Sun, Paul E. J. Nulsen +6
We present results from a deep (174 ks) Chandra observation of the FR-II radio galaxy 3C 220.1, the central brightest cluster galaxy (BCG) of a 4 keV cluster at .…
Constraining the magnetic field in the TeV halo of Geminga with X-ray Observation
Ruo-Yu Liu, Chong Ge, Xiao-Na Sun +1
Recently, the High Altitude Water Cherenkov (HAWC) collaboration reported the discovery of the TeV halo around the Geminga pulsar. The TeV emission is believed to originate from in…
Can winds driven by active galactic nuclei account for the extragalactic gamma-ray and neutrino backgrounds?
Ruo-Yu Liu, Kohta Murase, Susumu Inoue +2
Various observations are revealing the widespread occurrence of fast and powerful winds in active galactic nuclei (AGNs) that are distinct from relativistic jets, likely launched f…
