The Initial Conditions of Stellar Protocluster Formation : III. The Herschel counterparts of the Spitzer Dark Cloud catalogue
(2016-06-01)
Galactic plane surveys of pristine molecular clouds are key for establishing a Galactic-scale view of the earliest stages of star formation. For this reason Peretto & Fuller (2009) built an unbiased sample of IRDCs in the ...
Molecular gas and star formation in the Tidal Dwarf Galaxy VCC 2062
(2016-06-01)
The physical mechanisms driving star formation (SF) in galaxies are still not fully understood. Tidal dwarf galaxies (TDGs), made of gas ejected during galaxy interactions, seem to be devoid of dark matter and have a ...
X-ray properties of the Youngest Radio Sources and their Environments
(2016-05-23)
We present the first results from our X-ray study of young radio sources classified as compact symmetric objects (CSOs). Using the Chandra X-ray Observatory we observed six CSOs for the first time in X-rays, and re-observed ...
High star formation rates in turbulent atomic-dominated gas in the interacting galaxies IC 2163 and NGC 2207
(2016-05-20)
CO observations of the interacting galaxies IC 2163 and NGC 2207 are combined with HI, Halpha and 24 microns to study the star formation rate (SFR) surface density as a function of the gas surface density. More than half ...
A Large Scale, Low Frequency Murchison Widefield Array Survey of Galactic HII regions between 260\340
(2016-05-17)
We have compiled a catalogue of HII regions detected with the Murchison Widefield Array (MWA) between 72 and 231MHz. The multiple frequency bands provided by the MWA allow us identify the characteristic spectrum generated ...
The Population of Compact Radio Sources in the Orion Nebula Cluster
(2016-05-10)
We present a deep centimeter-wavelength catalog of the Orion Nebula Cluster (ONC), based on a 30h single-pointing observation with the Karl G. Jansky Very Large Array in its high-resolution A-configuration using two 1 GHz ...
Probing the Dragonfish star-forming complex: : the ionizing population of the young massive cluster Mercer 30
(2016-05-01)
The Dragonfish Nebula has been recently claimed to be powered by a superluminous but elusive OB association. Instead, systematic searches in near-infrared photometric surveys have found many other cluster candidates on ...
The SAMI Galaxy Survey: : extraplanar gas, galactic winds, and their association with star formation history
(2016-04-01)
We investigate a sample of 40 local, main-sequence, edge-on disc galaxies using integral field spectroscopy with the Sydney-AAO Multi-object Integral field spectrograph (SAMI) Galaxy Survey to understand the link between ...
A search for white dwarfs in the Galactic plane: : the field and the open cluster population
(2016-04-01)
We investigated the prospects for systematic searches of white dwarfs at low Galactic latitudes, using the VLT Survey Telescope (VST) H$\alpha$ Photometric Survey of the Galactic plane and Bulge (VPHAS+). We targeted 17 ...
A SCUBA-2 survey of FeLoBAL QSOs : Are FeLoBALs in a `transition phase' between ULIRGs and QSOs?
(2016-04-01)
It is thought that a class of broad absorption line (BAL) QSOs, characterised by Fe absorption features in their UV spectra (called `FeLoBALs'), could mark a transition stage between the end of an obscured starburst event ...
