PublicationA Bayesian estimation of the Milky Way's circular velocity curve using Gaia DR3
Aims: Our goal is to calculate the circular velocity curve of the Milky Way, along with corresponding uncertainties that quantify various sources of systematic...

PublicationA Be-type star with a black-hole companion
Stellar-mass black holes have all been discovered through X-ray emission, which arises from the accretion of gas from their binary companions (this gas is...

PublicationA binary merger origin for inflated hot Jupiter planets
We hypothesize that hot Jupiters with inflated sizes represent a separate planet formation channel, the merging of two low-mass stars. We show that the...

PublicationA bipolar-outflow object in the field of M 36.
We have discovered an object in the field of the Galactic open cluster [1]36 which exhibits a nebulous tail-like structure and a high velocity outflow. We first...

PublicationA Black Hole Nova Obscured by an Inner Disk Torus.
Stellar-mass black holes (BHs) are mostly found in X-ray transients, a subclass of X-ray binaries that exhibit violent outbursts. None of the 50 Galactic BHs...

PublicationA black hole X-ray binary at ̃100 Hz: multiwavelength timing of MAXI J1820+070 with HiPERCAM and NICER
We report on simultaneous sub-second optical and X-ray timing observations of the low-mass X-ray binary black hole candidate MAXI J1820+070. The bright 2018...

PublicationA black widow population dissection through HiPERCAM multiband light-curve modelling
Black widows are extreme millisecond pulsar binaries where the pulsar wind ablates their low-mass companion stars. In the optical range, their light curves vary...

PublicationA blind detection of a large, complex, Sunyaev-Zel'dovich structure
We present an interesting Sunyaev-Zel’dovich (SZ) detection in the first of the Arcminute Microkelvin Imager (AMI) ‘blind’, degree-square fields to have been...
