Abstract The Hubble constant, H 0, or its dimensionless equivalent, “little h”, is a fundamental cosmological property that is now known to an accuracy better than a few per cent. Despite its cosmological nature, little h commonly appears in the measured properties of individual galaxies. This can pose unique challenges for users of such data, particularly with survey data. In this paper we show how little h arises in the measurement of galaxies, how to compare like-properties from different… 

Where do galaxies end? Comparing measurement techniques of hydrodynamic-simulation galaxies’ integrated properties

Using the suite of high-resolution zoom re-simulations of individual haloes by Martig et al., and the large-scale simulation \emph{MassiveBlack-II}, we examine the differences in measured galaxy

Weak Lensing by Galaxy Clusters: from Pixels to Cosmology

The story of the origin and evolution of our Universe is told, equivalently, by space-time itself and by the structures that grow inside of it. Clusters of galaxies are the frontier of bottom-up

WHAT DO SIMULATIONS PREDICT FOR THE GALAXY STELLAR MASS FUNCTION AND ITS EVOLUTION IN DIFFERENT ENVIRONMENTS?

We present a comparison between the observed galaxy stellar mass function and the one predicted from the De Lucia & Blaizot semi-analytic model applied to the Millennium Simulation, for cluster

Toward Accurate Modeling of Galaxy Clustering on Small Scales: Constraining the Galaxy-halo Connection with Optimal Statistics

Applying halo models to analyze the small-scale clustering of galaxies is a proven method for characterizing the connection between galaxies and their host halos. Such works are often plagued by

Abstract The birth of stars and the formation of galaxies are cornerstones of modern astrophysics. While much is known about how galaxies globally and their stars individually form and evolve, one

ERRATUM: “MASSIVE STAR-FORMING HOST GALAXIES OF QUASARS ON SLOAN DIGITAL SKY SURVEY STRIPE 82” (2014, ApJ, 780, 162)

The absolute magnitudes ( 0 . 3 M X where X = g or i ) and stellar masses ( M star ) of the quasar host galaxies reported in the published version of this paper should have been designated as 0 . 3 M

Galaxy formation efficiency and the multiverse explanation of the cosmological constant with EAGLE simulations

Models of the very early Universe, including inflationary models, are argued to produce varying universe domains with different values of fundamental constants and cosmic parameters. Using the

Black Hole Mass Scaling Relations for Spiral Galaxies. I. MBH–M*,sph

The (supermassive black hole mass, MBH)–(bulge stellar mass, ) relation is, obviously, derived using two quantities. We endeavor to provide accurate values for the latter via detailed multicomponent

THE THEORETICAL ASTROPHYSICAL OBSERVATORY: CLOUD-BASED MOCK GALAXY CATALOGS

We introduce the Theoretical Astrophysical Observatory (TAO), an online virtual laboratory that houses mock observations of galaxy survey data. Such mocks have become an integral part of the modern

THE z < 1.2 ?> OPTICAL LUMINOSITY FUNCTION FROM A SAMPLE OF ∼410,000 GALAXIES IN BOÖTES

Using a sample of ∼410,000 galaxies to a depth of I AB = 24 ?> over 8.26 deg2 in the Boötes field (∼10 times larger than the z ∼ 1 ?> luminosity function (LF) studies in the prior literature), we

Slipher, galaxies, and cosmological velocity fields

By 1917, V.M. Slipher had singlehandedly established a tendency for 'spiral nebulae' to be redshifted (21 out of 25 cases). From a modern perspective, it could seem surprising that the expansion of

This paper presents the first cosmological results based on Planck measurements of the cosmic microwave background (CMB) temperature and lensing-potential power spectra. We find that the Planck
