(Biphenyl-2-yl)bromidobis(2-methyltetrahydrofuran-[kappa]O)magnesium(II)
In the title Grignard reagent, [MgBr(C12H9)(C5H10O)2], the Mg centre adopts a distorted tetrahedral MgCO2Br arrangement. The dihedral angle between the two aromatic rings of the biphenyl residue is 44.00 (14)°. Each molecule incorporates one R- and one S-configured 2-methyltetrahydrofuran molecule. Key indicators: single-crystal X-ray study; T = 173 K; mean σ(CâC) = 0.007 Ă
; R factor = 0.045; wR factor = 0.108; data-to-parameter ratio = 17.4

Detailed Shape and Evolutionary Behavior of the X-ray Luminosity Function of Active Galactic Nuclei
We construct the rest-frame 2--10 keV intrinsic X-ray luminosity function of
Active Galactic Nuclei (AGNs) from a combination of X-ray surveys from the
all-sky Swift BAT survey to the Chandra Deep Field-South. We use ~3200 AGNs in
our analysis, which covers six orders of magnitude in flux. The inclusion of
the XMM and Chandra COSMOS data has allowed us to investigate the detailed
behavior of the XLF and evolution. In deriving our XLF, we take into account
realistic AGN spectrum templates, absorption corrections, and probability
density distributions in photometric redshift. We present an analytical
expression for the overall behavior of the XLF in terms of the
luminosity-dependent density evolution, smoothed two power-law expressions in
11 redshift shells, three-segment power-law expression of the number density
evolution in four luminosity classes, and binned XLF. We observe a sudden
flattening of the low luminosity end slope of the XLF slope at z>~0.6. Detailed
structures of the AGN downsizing have been also revealed, where the number
density curves have two clear breaks at all luminosity classes above log LX>43.
The two break structure is suggestive of two-phase AGN evolution, consisting of
major merger triggering and secular processes.Comment: 39 Pages, 9 figures. ApJ in pres

Nebular Line Emission During the Epoch of Reionization
Nebular emission lines associated with galactic HII regions carry information
about both physical properties of the ionised gas and the source of ionising
photons as well as providing the opportunity of measuring accurate redshifts
and thus distances once a cosmological model is assumed. While nebular line
emission has been extensively studied at lower redshift there are currently
only few constraints within the epoch of reionisation (EoR, ), chiefly due
to the lack of sensitive near-IR spectrographs. However, this will soon change
with the arrival of the Webb Telescope providing sensitive near-IR spectroscopy
covering the rest-frame UV and optical emission of galaxies in the EoR. In
anticipation of Webb we combine the large cosmological hydrodynamical
simulation Bluetides with photoionisation modelling to predict the nebular
emission line properties of galaxies at . We find good agreement
with the, albeit limited, existing direct and indirect observational
constraints on equivalent widths though poorer agreement with luminosity
function constraints.Comment: 17 pages, accepted to MNRAS, significant modification from v1.0 data
