Gravitational Wave Detection with Relative Astrometry using Roman's Galactic Bulge Time Domain Survey
Kris Pardo, Tzu-Ching Chang, Olivier Doré +1
Gravitational waves (GWs) are a new avenue of observing our Universe. So far, we have seen them in the ~10-100 Hz range, and there are hints that we might soon detect them in the n…
Transient obscuration event captured in NGC~3227 II. Warm absorbers and obscuration events in archival XMM-Newton and NuSTAR observations
Yijun Wang, Jelle Kaastra, Missagh Mehdipour +18
The relation between warm absorber (WA) outflows of AGN and nuclear obscuration activities caused by optically-thick clouds (obscurers) crossing the line of sight is unclear. NGC 3…
X-ray spectral variations of synchrotron peak in BL Lacs
Yijun Wang, Shifu Zhu, Yongquan Xue +3
The spectral energy distribution of blazars around the synchrotron peak can be well described by the log-parabolic model that has three parameters: peak energy (), pe…
Systematic investigation of X-ray spectral variability of TeV blazars during flares in the era
Yijun Wang, Yongquan Xue, Shifu Zhu +1
Utilizing all the 16-year observations, we analyze the X-ray spectra of 32 TeV blazars, and perform a systematic investigation of X-ray spectral variability for the 5 bright…
