    Massive Dead Disk Galaxy Challenges Theories of Galaxy Evolution

    June 22, 2017, Categories  Astronomy/Space

    This artist's concept shows what the young, dead, disk galaxy MACS2129-1, right, would look like when compared with the Milky Way galaxy, left. Although three times as massive as the Milky Way, it is only half the size. MACS2129-1 is also spinning more than twice as fast as the Milky Way. Note that regions of Milky Way are blue from bursts of star formation, while the young, dead galaxy is yellow, signifying an older star population and no new star birth. Credit: NASA, ESA, and Z.

    By combining the power of a “natural lens” in space with the capability of Hubble Space Telescope, astronomers made a surprising discovery – the first example of a compact yet massive, fast-spinning, disk-shaped galaxy that stopped making stars only a few billion years after the big bang...

    MUSE and X-shooter instruments on the Very Large Telescope (VLT) at ESO’s Paranal Observatory in Chile have been used to study an ongoing collision between two galaxies, known collectively as IRAS F23128-5919, 600 million light-years from Earth. The group observed the outflows – that originate near the supermassive black hole at the heart of the pair’s southern galaxy, and have found the first clear evidence that stars are being born within them. The discovery has many consequences for understanding galaxy properties and evolution.

    Such galactic outflows are driven by the huge energy output from the active and turbulent centres of galaxies...

    Young, Thin and Hyperactive: That’s what Outlier Galaxies look like

    A new model explains the exceptiobns to the galaxy main model sequence

    A new model explains the exceptions to the galaxy main model sequence

    The more massive, or full of stars, a galaxy is, the faster the stars in it are formed. This seems to be the general rule, which is contradicted, however, by some abnormal cases, for example thin (not massive) galaxies that are hyperactive in their star formation. Until now the phenomenon had been explained by catastrophic external events like galaxies colliding and merging, but a new theory offers an alternative explanation, related to an in situ (internal) process of galaxy evolution. The new theory correctly reproduces the behaviour of both normal and abnormal (or outlier) galaxies, and may be further tested by new observations.

    If we put the galaxies for which we have the relevant data into a graph relating the mass ...

    Observable Universe contains 2 trillion Galaxies, 10X more than previously thought

    October 15, 2016, Categories  Astronomy/Space

    This Hubble Space Telescope view reveals thousands of galaxies stretching back into time across billions of light-years of space. The image covers a portion of a large galaxy census called the Great Observatories Origins Deep Survey (GOODS). Besides the myriad of galaxies visible in this image, only 10 percent of the total number of galaxies in the universe are observable for the current generation of telescopes, according to a new analysis of the GOODS and other Hubble deep-field surveys. The study's researchers concluded that at least 10 times more galaxies exist in the observable universe than previously thought. The analysis places the universe's estimated population at, minimally, 2 trillion galaxies. According to the research, about 90 percent of galaxies in the observable universe are too faint and too far away to be seen with present-day telescopes. Credit: NASA, ESA, the GOODS Team, and M.
