Galaxy Concentrations are Trimodal

We have analysed the distribution of inclination-corrected galaxy concentrations in the Sloan Digital Sky Survey. We find that unlike most galaxy properties, which are distributed bimodally, the distribution of concentrations is trimodal: it exhibits three distinct peaks. The newly-discovered intermediate peak, which consists of early-type spirals and lenticulars, may contain ∼ 60% of the numbe...

Introducing TRIGRAPH - Trimodal writer identification

With this presentation, we want to introduce the recently started TRIGRAPH project. The aim of this project is to develop techniques that can be used for forensic writer identification, using recent advances in pattern recognition and image processing, new insights in automatically derived handwriting features, user interface development, and innovations in forensic writer identification system...

Are the HDF Galaxy Counts Whole Numbers?

The Hubble Deep Field (HDF) offers the best view to date of the optical sky at faint magnitudes and small angular scales. Early reports suggested that faint source counts continue to rise to the completeness limit of the data. In this letter, we investigate the possibility that some of these sources are in fact giant HII regions or merger fragments within the same galaxy, rather than individual...

Are extrasolar oceans common throughout the Galaxy?

Light and cold extrasolar planets such as OGLE 2005-BLG-390Lb, a 5.5 Earth-mass planet detected via microlensing, could be frequent in the Galaxy according to some preliminary results from microlensing experiments. These planets can be frozen rockyor ocean-planets, situated beyond the snow line and, therefore, beyond the habitable zone of their system. They can nonetheless host a layer of liqui...

Are we missing baryons in Galaxy Clusters?

The recent constraints on the cosmological parameters put from the observations of the WMAP satellite limit the cosmic baryon fraction in a range that is larger than, and marginally consistent with, what is measured in galaxy clusters. This rises the question whether or not we are considering all the ingredients of cluster baryonic budget. Carefully weighing the baryons in X-ray emitting plasma...
