Investigating the Hard State of MAXI J1820+070: A Comprehensive Bayesian Approach to Black Hole Spin and Accretion Properties
Sachin D. Dias, Simon Vaughan, Mehdy Lefkir +1
We analyse the X-ray spectrum of the black hole X-ray binary MAXI J1820+070 using observations from XMM-Newton and NuSTAR during 'hard' states of its 2018-2019 outburst. We take a…
Confirming new white dwarf-ultracool dwarf binary candidates
Miriam Hogg, Sarah Casewell, Graham Wynn +8
We present the results of a study to discover prospective new white dwarf-L dwarf binaries as identified by their near-infrared excesses in the UKIDSS catalogue. We obtained optica…
Does slow and steady win the race? Investigating feedback processes in giant molecular clouds
L. Garratt-Smithson, G. A. Wynn, C. Power +1
We investigate the effects of gradual heating on the evolution of turbulent molecular clouds of mass M and virial parameters ranging between . This…
X-ray orbital modulation of a white dwarf accreting from an L dwarf: The system SDSS J121209.31+013627.7
B. Stelzer, D. de Martino, S. L. Casewell +2
In an XMM-Newton observation of the binary SDSS J121209.31+013627.7, consisting of a white dwarf and an L dwarf, we detect X-ray orbital modulation as proof of accretion from the s…
High-resolution optical spectroscopy of RS Ophiuchi during 2008 -- 2009
A. Somero, P. Hakala, G. A. Wynn
RS Ophiuchi is a symbiotic variable and a recurrent nova. We have monitored it with the Nordic Optical Telescope and obtained 30 high resolution (R=46 000) optical spectra over one…
A LOFAR mini-survey for low-frequency radio emission from the nearest brown dwarfs
Ben Burningham, M. Hardcastle, J. D. Nichols +9
We have conducted a mini-survey for low-frequency radio emission from some of the closest brown dwarfs to the Sun with rapid rotation rates: SIMP J013656.5+093347, WISEPC J150649.9…
