On the Root Cause of the Host “Mass Step” in the Hubble Residuals of Type Ia Supernovae
It is well established that the Hubble residuals of Type Ia supernovae (SNe Ia) show the luminosity step with respect to their host galaxy stellar masses.

First results from the IllustrisTNG simulations: the galaxy colour bimodality [PDF]
We introduce the first two simulations of the IllustrisTNG project, a next generation of cosmological magnetohydrodynamical simulations, focusing on the optical colors of galaxies.

The clustering of the SDSS DR7 Main Galaxy Sample I: a 4 per cent distance measure at z=0.15 [PDF]
We create a sample of spectroscopically identified galaxies with z < 0.2 from the Sloan Digital Sky Survey (SDSS) Data Release 7 (DR7), covering 6813 deg(2).

Automatic quantitative morphological analysis of interacting galaxies [PDF]
The large number of galaxies imaged by digital sky surveys reinforces the need for computational methods for analyzing galaxy morphology. While the morphology of most galaxies can be associated with a stage on the Hubble sequence, morphology of galaxy ...

Spectroscopic Target Selection in the Sloan Digital Sky Survey: The Main Galaxy Sample [PDF]
We describe the algorithm that selects the main sample of galaxies for spectroscopy in the Sloan Digital Sky Survey (SDSS) from the photometric data obtained by the imaging survey.

Metric completions, the Heine-Borel property, and approachability
We show that the metric universal cover of a plane with a puncture yields an example of a nonstandard hull properly containing the metric completion of a metric space.

Counterrotation in Galaxies [PDF]
The phenomenon of counterrotation is observed when two galaxy components have their angular momenta projected antiparallel onto the sky. It follows that if the two components rotate around the same axis, the counter-rotation is intrinsic. On the contrary the counterrotation is only apparent if the rotation axes are misaligned and the line-of-sight lies

The Millennium Galaxy Catalogue: Galaxy Bimodality [PDF]
AbstractGalaxy bimodality is caused by the bulge-disc nature of galaxies as opposed to two distinct galaxy classes. This is evident in the colour-structure plane which clearly shows that elliptical galaxies (bulge-only) lie in the red compact peak and late-type spiral galaxies (disc-dominated) lie in the blue diffuse peak.
