ASKAP discovery of a pair of large radio bubbles: on the origin of odd radio circles
Renzhi Su, Minfeng Gu, Hengxiao Guo +9
We report the serendipitous discovery of a large, low-surface-brightness radio bubble in 944 MHz continuum data from the ASKAP Evolutionary Map of the Universe (EMU) survey. The st…
The Transition from Galaxy-wide Gas Inflow to Outflow in Quasar Host Galaxies
Zhicheng He, Zhifu Chen, Guilin Liu +8
Galactic-wide outflows driven by active galactic nuclei (AGNs) is a routinely invoked feedback mechanism in galaxy evolution models. Hitherto, the interplay among the interstellar…
Discovery of spectacular quasar-driven superbubbles in red quasars
Lu Shen, Guilin Liu, Zhicheng He +7
Quasar-driven outflows on galactic scales are a routinely invoked ingredient for galaxy formation models. We report the discovery of ionized gas nebulae as traced by [O III] 500…
Asymmetric eROSITA bubbles as the evidence of a circumgalactic medium wind
Guobin Mou, Dongze Sun, Taotao Fang +6
The eROSITA bubbles are detected via the instrument with the same name. The northern bubble shows noticeable asymmetric features, including distortion to the west and enhancement i…
Evidence for quasar fast outflows being accelerated at the scale of tens of parsecs
Zhicheng He, Guilin Liu, Tinggui Wang +14
Quasar outflows may play a crucial role in regulating the host galaxy, although the spatial scale of quasar outflows remain a major enigma, with their acceleration mechanism poorly…
A sharp rise in the detection rate of broad absorption line variations in a quasar SDSS J141955.26+522741.1
Qinyuan Zhao, Zhicheng He, Guilin Liu +4
We present an analysis of the variability of broad absorption lines (BALs) in a quasar SDSS J141955.26+522741.1 at with 72 observations from the Sloan Digital Sky Survey…
