Extended H2 emission line sources from UWISH2
(2015-12-11)
We present the extended source catalogue for the UKIRT Wide Field Infrared Survey for H2 (UWISH2). The survey is unbiased along the inner Galactic Plane from l≈357deg to l≈65deg and |b| ≤ 1 ∘.5 and covers 209 deg2. A further ...
Centaurus A: constraints on the nature of the giant lobe filaments from XMM-Newton observations
(2015-12-11)
We report on deep XMM-Newton observations of the vertex filament in the southern giant lobe of the Fanaroff-Riley class I radio galaxy Centaurus A. We find no X-ray excess from the filament region and place a 3 sigma upper ...
Radio AGN in spiral galaxies
(2015-12-01)
Radio AGN in the nearby Universe are more likely to be found in galaxies with early-type morphology, the detection rate in spiral or late-type galaxies (LTGs) being around an order of magnitude lower. We combine the mJy ...
Gas dynamics in tidal dwarf galaxies : disc formation at z=0
(2015-12)
Tidal dwarf galaxies (TDGs) are recycled objects that form within the collisional debris of interacting/merging galaxies. They are expected to be devoid of non-baryonic dark matter, since they can form only from dissipative ...
Evolution of star formation in the UKIDSS Ultra Deep Survey Field - II : Star formation as a function of stellar mass between z=1.46 and z=0.63
(2015-12-01)
We present new results on the evolution of the cosmic star formation rate as a function of stellar mass in the SXDS-UDS field. We make use of narrow-band selected emission line galaxies in four redshift slices between z = ...
Extremely metal-poor stars from the cosmic dawn in the bulge of the Milky Way
(2015-11-26)
The first stars are predicted to have formed within 200 million years after the Big Bang, initiating the cosmic dawn. A true first star has not yet been discovered, although stars with tiny amounts of elements heavier than ...
Cold dust emission from X-ray AGN in the SCUBA-2 Cosmology Legacy Survey : dependence on luminosity, obscuration & AGN activity
(2015-11-21)
We study the 850um emission in X-ray selected AGN in the 2 sq-deg COSMOS field using new data from the SCUBA-2 Cosmology Legacy Survey. We find 19 850um bright X-ray AGN in a high-sensitivity region covering 0.89 sq-deg ...
Radio monitoring of the periodically variable IR source LRLL 54361: No direct correlation between the radio and IR emissions
(2015-11-12)
LRLL 54361 is an infrared source located in the star forming region IC 348 SW. Remarkably, its infrared luminosity increases by a factor of 10 during roughly one week every 25.34 days. To understand the origin of these ...
Tidal Dwarf Galaxies : Disc Formation at z=0
(2015-11-05)
Collisional debris around interacting and post-interacting galaxies often display condensations of gas and young stars that can potentially form gravitationally bound objects: Tidal Dwarf Galaxies (TDGs). We summarise ...
Radio Galaxy Zoo : host galaxies and radio morphologies derived from visual inspection
(2015-11-01)
We present results from the first twelve months of operation of Radio Galaxy Zoo, which upon completion will enable visual inspection of over 170,000 radio sources to determine the host galaxy of the radio emission and the ...
