Delayed Launch of Ultrafast Outflows in the Tidal Disruption Event AT2020afhd
Zikun Lin, Yanan Wang, De-Fu Bu +2
We report the detection and characterization of ultrafast outflows (UFOs) in the X-ray spectra of the tidal disruption event (TDE) AT2020afhd, based on observations from NICER, Swi…
UK APAP R-matrix electron-impact excitation cross-sections for modelling laboratory and astrophysical plasma
G. Del Zanna, G. Liang, J. Mao +1
Systematic R-matrix calculations of electron-impact excitation for ions of astrophysical interest have been performed since 2007 for many iso-electronic sequences as part of the UK…
Minor-merger induced star formation rejuvenation in an elliptical radio-loud quasar host, 3C 59
Yijun Wang, Tao Wang, Ke Xu +3
We report a rare case where an elliptical radio-loud quasar host, 3C 59, rejuvenates star formation activity through minor mergers with its nearby satellite galaxies. The inferred…
Ionized X-ray winds in the radio galaxy Mrk 6
Taishu Kayanoki, Junjie Mao, Yasushi Fukazawa
Active galactic nucleus (AGN) outflows including jets and ionized winds have been key phenomena such as jet collimation and AGN feedback to the host galaxy in astrophysics. Radio g…
