Predictions for ASKAP neutral hydrogen surveys [PDF]

, 2012
The Australian Square Kilometre Array Pathfinder (ASKAP) will revolutionize our knowledge of gas-rich galaxies in the Universe. Here we present predictions for two proposed extragalactic ASKAP neutral hydrogen (H I) emission-line surveys, based on semi ...

FOSSIL EVIDENCE FOR THE TWO-PHASE FORMATION OF ELLIPTICAL GALAXIES [PDF]

Astrophysical Journal, 2013
Massive early-type galaxies (ETGs) have undergone dramatic structural evolution over the last 10 Gyr. A companion paper shows that nearby elliptical galaxies with M* ⩾ 1.3 × 1011M☉ generically contain three photometric subcomponents: a compact inner ...

A systematic survey for infrared star clusters with |b| < 20° using 2MASS [PDF]

, 2006
We used star density maps obtained from the Two-Micron All-Sky Survey (2MASS) to obtain a sample of star clusters in the entire Galactic Plane with |b| < 20°. A total of 1788 star cluster candidates are identified in this survey.

The influence of the cluster environment on the star formation efficiency of 12 Virgo spiral galaxies [PDF]

, 2012
The influence of the environment on gas surface density and star formation efficiency of cluster spiral galaxies is investigated. We extend previous work on radial profiles by a pixel-to pixel analysis looking for asymmetries due to environmental ...
