An 8 hour characteristic time-scale in submillimetre light curves of Sagittarius A*
Jason Dexter, Brandon Kelly, Geoffrey C. Bower +4
We compile and analyse long term (~10 year) submillimetre (1.3, 0.87, 0.43 mm, submm) wavelength light curves of the Galactic centre black hole, Sagittarius A*. The 0.87 and 0.43 m…
Quasar Black Hole Mass Estimates in the Era of Time Domain Astronomy
Brandon C. Kelly, Tommaso Treu, Matthew Malkan +2
We investigate the dependence of the normalization of the high-frequency part of the X-ray and optical power spectral densities (PSD) on black hole mass for a sample of 39 active g…
Empirical Links between XRB and AGN accretion using the complete z<0.4 spectroscopic CSC/SDSS Catalog
Markos Trichas, Paul Green, Anca Constantin +8
Striking similarities have been seen between accretion signatures of Galactic X-ray binary (XRB) systems and active galactic nuclei (AGN). XRB spectral states show a V-shaped corre…
Indications of a sub-linear and non-universal Kennicutt-Schmidt relationship
Rahul Shetty, Brandon C. Kelly, Nurur Rahman +5
We estimate the parameters of the Kennicutt-Schmidt (KS) relationship, linking the star formation rate (Sigma_SFR) to the molecular gas surface density (Sigma_mol), in the STING sa…
Stacked reverberation lags at high redshift
S. Fine, T. Shanks, P. Green +9
Over the past 20years reverberation mapping has proved one of the most successful techniques for studying the local (<1pc) environment of super-massive black holes that drive activ…
