Tricky words, Prepositions & Wordiness

wordiness

tricky

in agreement -> simplify (e.g. agrees with)

• The obscuration from ray-traced galaxy gas can be in agreement -> simplify (e.g. agrees with) with observations, but is highly sensitive to the chosen feedback assumptions.
• With our assumed fiducial values we obtain () to () and are therefore also in agreement -> simplify (e.g. agrees with) with those observations.
• This indicates that at least some models reproduce fractions in agreement -> simplify (e.g. agrees with) with observation.

there is -> rephrase

• Also, there is -> rephrase the usual mass-dependent increase in metallicity.

there are -> rephrase

• In the EAGLE simulation, there are -> rephrase three parameters which affect the triggering, efficiency and impact of AGN feedback respectively.

respectively -> double-check that you are pairing lists here

• We therefore do not rely on the instantaneous accretion rates provided by the simulations see for Illustris and EAGLE respectively -> double-check that you are pairing lists here Sijacki2015,Rosas-Guevara2016.

double negatives

not have -> lack

• Combining this simple limit with the masses of Figure , we can now conclude that galaxies simply do not have -> lack the required gas to provide Compton-thick obscurers with substantial covering factors outside the central X.

Contractions

can not -> cannot

• Therefore we can not -> cannot distinguish whether galaxy-scale obscuration decreases toward the bright end, or increases toward the faint end.
• Physical processes giving rise to the luminosity and mass-dependent behaviour can not -> cannot be discussed rigorously within the scope of this paper.
• can not -> cannot be achieved by accumulating the galaxy gas over several kpc.

Wrong comparisons

large fraction -> high fraction

• Assuming sampling from random viewing angles, the large fraction -> high fraction of obscured AGN implies large covering fractions.

Ambiguous

Colloquial phrases and formal equivalents (not comprehensive, see above)

type of -> rephrase, colloquial

• However the result holds independently of the geometry of the gas, the type of -> rephrase, colloquial galaxy and is also applicable to mergers.

Common mistakes (A&A frequent changes)

albeit -> although (Albeit means "although it be", so it cannot be used with another verb)

• The evolutionary model also explains why bright AGN are less frequently found to be mildly obscured than faint AGN Ueda2003,Silverman2008,Ebrero2009,Ueda2014,Buchner2015,Aird2015, albeit -> although (Albeit means "although it be", so it cannot be used with another verb) only qualitatively Hopkins2005,Hopkins2006OriginModel.
• The Compton-thick fraction here has been assumed to be constant, albeit -> although (Albeit means "although it be", so it cannot be used with another verb) we note that Ricci2016 claims a luminosity-dependence of the Compton-thick fraction.

compare to -> compare with (unless plural follows / no differentiation)

• We now compare to -> compare with (unless plural follows / no differentiation) measurements of the obscured fraction of Compton-thin AGN from surveys.
• We then compare to -> compare with (unless plural follows / no differentiation) observations.
• We focus on the fraction of AGN with at redshift , and compare to -> compare with (unless plural follows / no differentiation) EAGLE physics variations in Figure X. Observations find a fraction around X.

decrease of -> decrease in

• At the highest luminosities, an Eddington limit is required to explain the steep decrease of -> decrease in the luminosity function Aird2013.

Due to -> Owing to, Because of, X causes, as a result of (Due to is ambiguous)

• Due to -> Owing to, Because of, X causes, as a result of (Due to is ambiguous) the host galaxy, a constant fraction is present at all luminosities and masses.

in the following -> in the next/subsequent X, in the following way

• We use this in the following -> in the next/subsequent X, in the following way sections to disentangle the AGN nuclear obscurer from the galaxy-scale obscurer (Section ), and to describe their behaviour as a function of accretion luminosity, host galaxy stellar mass and redshift (Section ).

like -> such as, similar to, the same as

• This is a useful summary of observational constraints for torus modellers who would like -> such as, similar to, the same as to reproduce this behaviour.

quite -> ambiguous, reword (rather is also ambiguous)

• However, we can use observed obscured AGN fractions to exclude simulations which overproduce them, as these observations are apparently quite -> ambiguous, reword (rather is also ambiguous) sensitive to the assumed physics.

quite -> ambiguous, reword (rather is also ambiguous)

• However, we can use observed obscured AGN fractions to exclude simulations which overproduce them, as these observations are apparently quite -> ambiguous, reword (rather is also ambiguous) sensitive to the assumed physics.

Since -> Because, After which

• Since -> Because, After which the obscuration is host mass dependent, the obscurer is arguably the host galaxy itself.
• Since -> Because, After which neither semi-analytic nor hydro-dynamic cosmological simulations can resolve the nuclear obscurer of AGN, we present a sub-grid model for post-processing.

as well as -> Overused; don't you mean "and" in a specific instance?

• Towards the Galactic Center columns with can be found in the Central Molecular Zone Morris1996,Molinari2011, as well as -> Overused; don't you mean "and" in a specific instance? in the equivalent central zones of nearby AGN host galaxies Prieto2014.
• Figure shows results from surveys at the peak of the accretion history ( panels) from Ueda2014 and Buchner2015, as well as -> Overused; don't you mean "and" in a specific instance? surveys which include the local Universe Burlon2011,Ueda2014,Aird2015,Ricci2016.
• * We propose that the remaining Compton-thin sky is obscured by galaxy-scale gas as well as -> Overused; don't you mean "and" in a specific instance? a nuclear Compton-thin obscurer according to the formula:
• Evidence for the low-luminosity decline was found in surveys of the local Universe Burlon2011,Brightman2011b as well as -> Overused; don't you mean "and" in a specific instance? at high redshifts Buchner2015.
• Further relevant for this work it also produces galaxies with realistic galaxy morphologies Schaye2015 and gas contents consistent with observations of CO and HI Bahe2015 as well as -> Overused; don't you mean "and" in a specific instance? H Lagos2015.
• The EAGLE reference simulation in a large cosmological volume (L0100N1504REFERENCE) belongs to the latter group, as well as -> Overused; don't you mean "and" in a specific instance? the simulation run in medium-size volumes (L0025N0752REFERENCE, L0025N0752RECALIBRATED).

Prepositions

associated to -> associated with

• Additionally, a substantial part of the faint AGN population is probably associated to -> associated with secular triggering mechanisms e.g.

assumption of -> assumption about

• Under the assumption of -> assumption about black hole mass downsizing, i.e., that the average accreting black hole is more massive at high redshift than at low redshift, the turn-over luminosity decreases over cosmic time.

match with -> match

• However, these variations can be excluded based on their mismatch with -> match other observations, e.g.

My favorite mistakes

shades -> shading
