Redshifted HI and OH absorption in radio galaxies and quasars

From a survey for redshifted HI 21-cm and OH 18-cm absorption in the hosts of a sample of radio galaxies and quasars, we detect HI in three of the te…

A Search for Multi-Planet Systems Using the Hobby-Eberly Telescope

Extrasolar multiple-planet systems provide valuable opportunities for testing theories of planet formation and evolution. The architectures of the kn…

The Anglo-Australian Planet Search. XXII. Two New Multi-Planet Systems

We report the detection of two new planets from the Anglo-Australian Planet Search. These planets orbit two stars each previously known to host one p…

On the absence of molecular absorption in high redshift millimetre-ba…

We have undertaken a search for millimetre-wave band absorption (through the CO and HCO+ rotational transitions) in the host galaxies of reddened rad…

Infrared Dark Clouds in the Small Magellanic Cloud?

We have applied the unsharp-masking technique to the 24 $\mu$m image of the Small Magellanic Cloud (SMC), obtained with the Spitzer Space Telescope, …

Spectral imaging of the Central Molecular Zone in multiple 7-mm mol…

We have imaged 24 spectral lines in the Central Molecular Zone (CMZ) around the Galactic Centre, in the range 42 to 50 GHz. The lines include emissio…

Calculation of parity non-conserving optical rotation in iodine at 13…

We examine the feasibility of a parity non-conserving (PNC) optical rotation experiment for the $^2$P$_{3/2}\rightarrow ^2$P$_{1/2}$ transition of at…

Origin of rotational kinematics in the globular cluster system of M31…

We propose that the rotational kinematics of the globular cluster system (GCS) in M31 can result from a past major merger event that could have forme…

The amplitude of solar oscillations using stellar techniques

The amplitudes of solar-like oscillations depend on the excitation and damping, both of which are controlled by convection. Comparing observations wi…

GJ 832c: A super-earth in the habitable zone

We report the detection of GJ 832c, a super-Earth orbiting near the inner edge of the habitable zone of GJ 832, an M dwarf previously known to host a…

Spatial variation in the fine-structure constant -- new results from …

(abridged) We present a new analysis of a large sample of quasar absorption-line spectra obtained using UVES (the Ultraviolet and Visual Echelle Spec…

Transition amplitudes, polarizabilities and energy levels within opti…

We discuss possible search for optical transitions in Sm13+ and Sm14+ using ab initio calculations of differential dynamic polarizability. We calcula…

Spectral imaging of the Sagittarius B2 region in multiple 7-mm molecu…

We have undertaken a spectral-line imaging survey of a 6 x 6 arcmin^2 area around Sgr B2 near the centre of the Galaxy, in the range from 30 to 50 GH…

The Frequency of Low-Mass Exoplanets. II. The `Period Valley'

Radial-velocity planet search campaigns are now beginning to detect low-mass "Super-Earth" planets, with minimum masses M sin i < 10 M_earth. Using t…
