Recovering Density Fields inside Quasar Proximity Zones at
Huanqing Chen, Nickolay Y. Gnedin
The matter density field at is very challenging to probe. One of the traditional probes of the low density IGM that works successfully at lower redshifts is the Lyman-alp…
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 Distribution and Evolution of Quasar Proximity Zone Sizes
Huanqing Chen, Nickolay Y. Gnedin
In this paper, we study the sizes of quasar proximity zones with synthetic quasar absorption spectra obtained by post-processing a Cosmic Reionization On Computers (CROC) simulatio…
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…
