We present an analysis of galaxy–galaxy weak gravitational lensing (GGL) in chameleon f(R) gravity – a leading candidate of non-standard gravity models. For the analysis, we have created mock galaxy catalogues based on dark matter haloes from two set... Read More about Galaxy–galaxy weak gravitational lensing in f(R) gravity.

Lense-Thirring precession in ULXs as a possible means to constrain the neutron star equation-of-state (2017)
Journal Article

The presence of neutron stars in at least three ultraluminous X-ray sources is now firmly established and offers an unambiguous view of super-critical accretion. All three systems show long-timescale periods (60-80 days) in the X-rays and/or optical,...

Monthly Notices of the Royal Astronomical Society, 474(4), 5076-5104. https://doi.org/10.1093/mnras/stx3016

We analyse the velocity dispersion properties of 472 z ∼ 0.9 star-forming galaxies observed as part of the KMOS Redshift One Spectroscopic Survey (KROSS). The majority of this sample is rotationally dominated (83 ± 5 per cent with vC/σ0 > 1) but also...

We present a quantitative model for magneto-optical traps operating on narrow transitions, where the transition linewidth and the recoil shift are comparable. We combine a quantum treatment of the light scattering process with a Monte-Carlo simulatio...

We present an analysis of the average spectral properties of 12,000 SDSS quasars as a function of accretion disc inclination, as measured from the equivalent width of the [OIII] 5007Å line. The use of this indicator on a large sample of quasars from... Read More about EW[OIII] as an Orientation Indicator for Quasars: Implications for the Torus.

Maxi-sizing the trilinear Higgs self-coupling: how large could it be? (2017)

In order to answer the question on how much the trilinear Higgs self-coupling could deviate from its Standard Model value in weakly coupled models, we study both theoretical and phenomenological constraints. As a first step, we discuss this question... Read More about Maxi-sizing the trilinear Higgs self-coupling: how large could it be?.
