Galaxy and Mass Assembly (GAMA) : the life and times of L-star galaxies
(2013-05-01) - Journal article
In this work, we investigate in detail the effects the local environment (groups and pairs) has on galaxies with stellar mass similar to the Milky Way (L* galaxies). A volume limited sample of 6150 galaxies are visually ...
Imaging observations of magnetic reconnection in a solar eruptive flare
(2017-01-31) - Journal article
Solar flares are among the most energetic events in the solar atmosphere. It is widely accepted that flares are powered by magnetic reconnection in the corona. An eruptive flare is usually accompanied by a coronal mass ...

Magnetohydrostatic modelling of stellar coronae
(2016-02-11) - Journal article
We introduce to the stellar physics community a method of modelling stellar coronae that can be considered to be an extension of the potential field. In this approach, the magnetic field is coupled to the background ...
Galaxy And Mass Assembly (GAMA) : blue spheroids within 87 Mpc
(2018-03-21) - Journal article
In this paper we test if nearby blue spheroid (BSph) galaxies may become the progenitors of star-forming spiral galaxies or passively-evolving elliptical galaxies. Our sample comprises 428 galaxies of various morphologies ...
Cosmology with AGN dust time lags -- Simulating the new VEILS survey
(2017-01-11) - Journal article
The time lag between optical and near-infrared continuum emission in active galactic nuclei (AGN) shows a tight correlation with luminosity and has been proposed as a standardizable candle for cosmology. In this paper, we ...
A super-Jupiter orbiting a late-type star : a refined analysis of microlensing event OGLE-2012-BLG-0406
(2014-02-10) - Journal article
We present a detailed analysis of survey and follow-up observations of microlensing event OGLE-2012-BLG-0406 based on data obtained from 10 different observatories. Intensive coverage of the light curve, especially the ...
Formation of S0 galaxies through mergers : explaining angular momentum and concentration change from spirals to S0s
(2015-07) - Journal article
The CALIFA team has recently found that the stellar angular momentum and concentration of late-type spiral galaxies are incompatible with those of lenticular galaxies (S0s), concluding that fading alone cannot satisfactorily ...
Dependence of GAMA galaxy halo masses on the cosmic web environment from 100 deg2 of KiDS weak lensing data
(2016-11-11) - Journal article
Galaxies and their dark matter haloes are part of a complex network of mass structures, collectively called the cosmic web. Using the tidal tensor prescription these structures can be classified into four cosmic environments: ...
The Sloan Digital Sky Survey Reverberation Mapping project: : no evidence for evolution in the M•-σ* Relation to z~1
(2015-06-01) - Journal article
We present host stellar velocity dispersion measurements for a sample of 88 broad-line quasars at 0.1 <z <1 (46 at z > 0.6) from the Sloan Digital Sky Survey Reverberation Mapping (SDSS-RM) project. High signal-to-noise ...
