Dissecting the gamma-ray emissions of the nearby galaxies NGC 1068 and NGC 253
Shunhao Ji, Zhongxiang Wang, Yi Xing +2
Intrigued by recent high-energy study results for nearby galaxies with gamma-ray emission and in particular NGC~1068 that has been detected as a neutrino-emitting source by the Ice…
A tera-electronvolt afterglow from a narrow jet in an extremely bright gamma-ray burst 221009A
LHAASO Collaboration
Some gamma-ray bursts (GRBs) have an afterglow in the tera-electronvolt (TeV) band, but the early onset of this afterglow has not been observed. We report observations with the Lar…
Can one-zone hadronuclear model explain the hard-TeV spectrum of BL Lac objects?
Wei-Jian Li, Rui Xue, Guang-Bo Long +4
Context. The intrinsic TeV emission of some BL Lacs are characterized by a hard spectrum (the hard-TeV spectrum) after correcting for the extragalactic background light. The hard-T…
A spectral hardening in the Fermi-LAT Data of 1ES 0502+675
Yuhang Zeng, Dahai Yan, Wen Hu +1
The -ray spectral feature of the blazar 1ES 0502+675 is investigated by using Fermi Large Area Telescope (Fermi-LAT) Pass 8 data (between 100 MeV and 300 GeV) covering from 2008…
H and He I absorption in HAT-P-32 b observed with CARMENES -- Detection of Roche lobe overflow and mass loss
S. Czesla, M. Lampón, J. Sanz-Forcada +22
We analyze two high-resolution spectral transit time series of the hot Jupiter HAT-P-32 b obtained with the CARMENES spectrograph. Our new XMM-Newton X-ray observations of the syst…
Constraining Evolution of Magnetic Field Strength in Dissipation Region of Two BL Lac Objects
Xu-Liang Fan, Da-Hai Yan, Qing-Wen Wu +1
With the assumption that the optical variability timescale is dominated by the cooling time of the synchrotron process for BL Lac objects, we estimate time dependent magnetic field…
