Measuring the Density Fields around Bright Quasars at with XQR-30 Spectra
Huanqing Chen, Anna-Christina Eilers, Sarah E. I. Bosman +10
Measuring the density of the intergalactic medium using quasar sightlines in the epoch of reionization is challenging due to the saturation of Lyman- absorption. Near a luminous…
Powerful t-SNE technique leading to clear separation of type-2 AGN and HII galaxies in BPT diagrams
XueGuang Zhang, Yanqiu Feng, Huan Chen +1
Narrow emission-line galaxies can be distinguished in the well-known BPT diagrams through narrow emission line properties. However, there are no boundaries visible to the naked eye…
The Role of Quasar Radiative Feedback on Galaxy Formation during Cosmic Reionization
Huanqing Chen
Recent observations have found that many quasar fields lack galaxies. This unexpected lack of galaxies may potentially be explained by quasar radiation feedback. In this…
Imprints of Mass Accretion History on the Shape of the Intracluster Medium and the Relation
Huanqing Chen, Camille Avestruz, Andrey V. Kravtsov +2
We use a statistical sample of galaxy clusters from a large cosmological -bodyhydrodynamics simulation to examine the relation between morphology, or shape, of the X-ray emit…
Constraints On Duty Cycles Of Quasars At Z 6
Huanqing Chen, Nickolay Y. Gnedin
We study the mass of quasar-hosting dark matter halos at z 6 and further constrain the fraction of dark matter halos hosting an active quasar and the quasar beaming…
