A new (2+1)D cluster finding algorithm based on photometric redshifts: large scale structure in the Chandra Deep Field South [PDF]
Aims: We study galaxy clustering and explore the dependence of galaxy properties on the the environment up to a redshift z~1, on the basis of a deep multi-band survey in the Chandra Deep Field South.

We introduce a two-particle correlation function (2PCF) for the Milky Way, constructed to probe spatial correlations in the orthogonal directions of the stellar disk in the Galactic cylindrical coordinates of R , ϕ , and z . We use this new tool to probe

Beyond spheroids and discs: classifications of CANDELS galaxy structure at 1.4 < z < 2 via principal component analysis [PDF]
To understand the processes driving galaxy morphology and star formation, we need a robust method to classify the structural elements of galaxies. Important but rare and subtle features may be missed by traditional spiral, elliptical, irregular or S ...

Galaxy And Mass Assembly (GAMA): the wavelength dependence of galaxy structure versus redshift and luminosity [PDF]
We study how the sizes and radial profiles of galaxies vary with wavelength, by fitting Sersic functions simultaneously to imaging in nine optical and near-infrared bands.

A galaxy-halo model of large-scale structure [PDF]
We present a new, galaxy-halo model of large-scale structure, in which the galaxies entering a given sample are the fundamental objects. Haloes attach to galaxies, in contrast to the standard halo model, in which galaxies attach to haloes.

The connection between galaxy structure and quenching efficiency [PDF]
Using data from the SDSS-DR7, including structural measurements from 2D surface brightness fits with GIM2D, we show how the fraction of quiescent galaxies depends on galaxy stellar mass $M_*$, effective radius $R_e$, fraction of $r-$band light in the ...

Mirror dark matter: Cosmology, galaxy structure and direct detection [PDF]
A simple way to accommodate dark matter is to postulate the existence of a hidden sector. That is, a set of new particles and forces interacting with the known particles predominantly via gravity.

MegaMorph – multiwavelength measurement of galaxy structure: physically meaningful bulge–disc decomposition of galaxies near and far [PDF]
Bulge–disc decomposition is a valuable tool for understanding galaxies. However, achieving robust measurements of component properties is difficult, even with high-quality imaging, and it becomes even more so with the imaging typical of large surveys. In

Unravelling the origin of large-scale magnetic fields in galaxy clusters and beyond through Faraday Rotation Measures with the SKA [PDF]
We investigate the possibility for the SKA to detect and study the magnetic fields in galaxy clusters and in the less dense environments surrounding them using Faraday Rotation Measures.

Molecular Structures of Other Galaxies Compared to That of the Galaxy [PDF]
Of the eleven galaxies with detected CO emission, eight have bright nuclear CO sources: M82, NGC 253, M51, NGC 5236, NGC 1068, Maffei 2 (Rickard et al. 1977a,b), NGC 6946, and IC 342 (Morris and Lo 1978). Two have disk-population CO sources and no detectable nuclear source (M31 and M81, Combes et al. 1977a), and one has no obvious nucleus (LMC, Huggins,
