We identify sources with extremely hard X-ray spectra (i.e., with photon indices of ${\rm{\Gamma }}\lesssim 0.6$) in the 13 deg2 NuSTAR serendipitous survey, to search for the most highly obscured active galactic nuclei (AGNs) detected at $\gt 10\,\m...

Piezoelectric and ferroelectric properties in the two-dimensional (2D) limit are highly desired for nanoelectronic, electromechanical, and optoelectronic applications. Here we report the first experimental evidence of out-of-plane piezoelectricity an... Read More about Out-of-Plane Piezoelectricity and Ferroelectricity in Layered α-In2Se3 Nanoflakes.

Determining the torus covering factors for a sample of type 1 AGN in the local Universe (2017)
Journal Article

In the unified scheme of active galactic nuclei, a dusty torus absorbs and then reprocesses a fraction of the intrinsic luminosity which is emitted at longer wavelengths. Thus, subject to radiative transfer corrections, the fraction of the sky covere... Read More about Determining the torus covering factors for a sample of type 1 AGN in the local Universe.

The relation between galaxy morphology and colour in the EAGLE simulation (2017)
Journal Article

We investigate the relation between kinematic morphology, intrinsic colour and stellar mass of galaxies in the EAGLE cosmological hydrodynamical simulation. We calculate the intrinsic u − r colours and measure the fraction of kinetic energy invested... Read More about The relation between galaxy morphology and colour in the EAGLE simulation.

Total π + p cross section extracted from the leading neutron spectra at the LHC (2017)
Journal Article

We use the very forward neutron energy spectra measured by the LHC forward experiment at 7 TeV to extract the πþp total cross section at center-of-mass energies in the range 2.3–3.5 TeV. To do this, we have to first isolate the π-exchange pole in for... Read More about Total π + p cross section extracted from the leading neutron spectra at the LHC.

We present new observations of the three nearest early-type galaxy (ETG) strong lenses discovered in the SINFONI Nearby Elliptical Lens Locator Survey (SNELLS). Based on their lensing masses, these ETGs were inferred to have a stellar initial mass fu...
