Recent observations have found that many z ∼ 6 quasar fields lack galaxies. This unexpected lack of galaxies may potentially be explained by quasar radiation feedback. In this paper, I present a suite of 3D radiative transfer cosmological simulations of quasar fields. I find that quasar radiation suppresses star formation in low-mass galaxies, mainly by photodissociating their molecular hydrogen. Photo-heating also plays a role, but only after ∼100 Myr. However, galaxies that already have… 
Three Lyα Emitting Galaxies within a Quasar Proximity Zone at z ∼ 5.8
Quasar proximity zones at correspond to overdense and overionized environments. Galaxies found inside proximity zones can therefore display features that would otherwise be masked by absorption in
Measuring the Density Fields around Bright Quasars at z ∼ 6 with XQR-30 Spectra
Measuring the density of the intergalactic medium using quasar sight lines in the epoch of reionization is challenging due to the saturation of Lyα absorption. Near a luminous quasar, however, the
The Distribution and Evolution of Quasar Proximity Zone Sizes
In this paper, we study the sizes of quasar proximity zones with synthetic quasar absorption spectra obtained by postprocessing a Cosmic Reionization On Computers (CROC) simulation. CROC simulations

The hidden satellites of massive galaxies and quasars at high redshift
Using cosmological, radiation-hydrodynamic simulations targeting a rare ${\approx}2 \times 10^{12} \, \rm {\rm M}_{\odot }$ halo at $z = 6$, we show that the number counts and internal properties
Active Galactic Nucleus Environments and Feedback to Neighboring Galaxies at z ∼ 5 Probed by Lyα Emitters
Active galactic nuclei (AGNs) in the high-redshift universe are thought to reside in overdense environments. However, recent works provide controversial results, partly due to the use of different
Rapidly star-forming galaxies adjacent to quasars at redshifts exceeding 6
TLDR
Observations of an emission line of singly ionized carbon in four galaxies at z > 6 that are companions of quasars and estimate star-formation rates in the companions of more than 100 solar masses per year, which can account for the population of massive elliptical galaxies in terms of the density of cosmic space.
Large-scale Environment of a z = 6.61 Luminous Quasar Probed by Lyα Emitters and Lyman Break Galaxies
Quasars (QSOs) hosting supermassive black holes are believed to reside in massive halos harboring galaxy overdensities. However, many observations revealed average or low galaxy densities around z ≳

The quasar lifetime tQ is one of the most fundamental quantities for understanding quasar evolution and the growth of supermassive black holes (SMBHs), but remains uncertain by several orders of

Effective stellar feedback is used in models of galaxy formation to drive realistic galaxy evolution. Models typically include energy injection from supernovae (SNe) as the dominant form of stellar
