ESO's VLT takes the search for young galaxies to new limits Staring for the equivalent of every night for two weeks at the same little patch of sky with ESO's Very Large Telescope, an international team of astronomers has found the extremely faint light from teenage galaxies billions of light years a...

It is one of the major goals of observational cosmology to trace the way galaxies formed and evolved and to compare it to predictions from theoretical models. It is therefore essential to know as precisely as possible how many galaxies were present in the Universe at different epochs. This is ea...

A new method to detect small, faint galaxies that spring up in the wake of violent galactic collisions has been devised by astronomers using the Spitzer Space Telescope. The method could shed light on how most of the galaxies near our own formed. The vast majority of local galaxies are "dwarfs" –...

Title: Minivoids in the Local Volume Authors: A. V. Tikhonov, I. D. Karachentsev We consider a sphere of 7.5 Mpc radius, which contains 355 galaxies with accurately measured distances, to detect the nearest empty volumes. Using a simple void detection algorithm, we found s...

First results from the Arecibo Galaxy Environment Survey (AGES) suggest the discovery of a new dark galaxy. The AGES survey, which started in January 2006, is the most sensitive, large-scale survey of neutral hydrogen to date. Neutral hydrogen is found in most galaxies and it is a key tool in the sea...

Title: Chandra X-ray Observations of Galaxies in an Off-Centre Region of the Coma Cluster Authors: A.E. Hornschemeier, B. Mobasher, D.M. Alexander, F.E. Bauer, M.W. Bautz, D. Hammer, B.M. Poggianti Researchers have performed a pilot Chandra X-ray telescope survey of an... < 10^-3). They do not have sufficient numbers of X-ray detected galaxies to directly measure the galaxy X-ray Luminosity Function (XLF). However, since they have a well-measured optical LF, they took this low X-ray to optical flux ratio for the 7 spectroscopically confirmed galaxies to translate the optical LF to an XLF. They find good agreement with Finoguenov et al. (2004), indicating that the X-ray emission per unit optical flux per galaxy is suppressed in clusters of galaxies, but extends this work to a specific off-centre environment in the Coma cluster. Finally, They report the discovery of a region of diffuse X-ray flux that might correspond to a small group interacting with the Coma Intra-Cluster Medium (ICM). Read More (PDF)

Solitary galaxies that live in vast, empty regions of space are forming stars at a surprisingly high rate, reveals the largest survey of galaxies ever made. The lonely galaxies may thrive because few galaxies are close enough to strip them of their star-forming gas. An overwhelming 95% of gala...

A major breakthrough in pinpointing some of the most primordial and violently star forming galaxies in the Universe has been made by a joint collaboration of UK and US astronomers using the Spitzer Space Telescope to resolve primordial galaxies initially detected by the James Clerk Maxwell teles...

Deep Gemini imaging of the cluster of galaxies Hydra I (also known as Abell 1060) at a distance of 54 Mpc (176 million light-years) has revealed an abundance of massive luminous metal-rich globular clusters that appears to impersonate ultra-compact dwarf galaxies. This is the richest population...

A team led by an Indiana University astronomer has found a sample of massive galaxies with properties that suggest they may have formed relatively recently.

Astronomers have caught a glimpse of galaxies that existed a mere 500 million years after the Big Bang, more than 13 billion years ago.
