We report on the analysis of a short XMM-Newton observation of the reddened Type 1 QSO 2MASS 234449+1221 first identified in the Two Micron All-Sky Survey. The underlying X-ray continuum is found to be typical of a broad-line active galaxy, with photon index Γ∼1.9. Low energy absorption can be modelled by a column N H ∼10 22 cm −2 of moderately ionised gas or a smaller column of cold gas. Addit...

We have determined the structure and kinematics of ionised gas in the weak oval bar of the archetypal Seyfert 1 galaxy, NGC 4151, using the TAURUS Fabry-Perot interferometer to simultaneously map the distribution and kinematics of Hβ emission. We also present broad-band ultraviolet imaging of the host galaxy, obtained with XMM-Newton, that shows the detailed distribution of star formation in th...

The hole mobilities in the GaAs1-xSbx system is been investigated for 0.0 ≤ x ≤ 1.0. Undoped room temperature mobilities are used to examine the scattering as a function of the Sb content. Two scattering mechanisms are considered: ionised impurity and alloy scattering. The alloy scattering potential is found to be 1.868 eV, which is about twice the theoretical value. Samples of various doping l...

Several radio-wave scintillation phenomena exhibit properties which are difficult to accommodate within the standard propagation model based on distributed Kolmogorov turbulence in the ionised ISM; here we discuss one such phenomenon, namely Extreme Scattering Events. By analysis of the data we demonstrate that these events are caused by ionised gas associated with selfgravitating, AU-sized gas...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/ bcr-2014-206795 A term male infant, 8 days old, was admitted to our neonatal intensive care unit with abnormal movements of the upper limbs. The infant was born in our hospital with birth weight of 3.2 kg and had an Apgar score of 8/9/9 at 1, 5 and 10 min, respectively. Th...

We present a linear analysis of the vertical structure and growth of the magnetorotational instability in stratified, weakly ionised accretion discs, such as protostellar and quiescent dwarf novae systems. The method includes the effects of the magnetic coupling, the conductivity regime of the fluid and the strength of the magnetic field, which is initially vertical. The conductivity is treated...

We have carried out a radio-wavelength imaging survey of 45 bright-rimmed clouds (BRCs), using the Australia Telescope Compact Array to characterise the physical properties in their ionised boundary layers. We detected radio emission from a total of 25 clouds and using a combination of Digitised Sky Survey and mid-infrared MSX 8 μm images classified the emission into that associated with the io...

We investigate the properties of the two-dimensional distribution and kinematics of ionised gas and stars in the central kiloparsecs of a matched sample of nearby active (Seyfert) and inactive galaxies, using the SAURON Integral Field Unit on the William Herschel Telescope. The ionised gas distributions show a range of low excitation regions such as star formation rings in Seyferts and inactive...
