The significant effects of stellar mass estimation on galaxy pair fractions

Philip J. Grylls, F. Shankar, C. Conselice

There exist discrepancies in measurements of the number and evolution of galaxy pairs. The pair fraction appears to be sensitive to both the criteria used to select pair fraction a…

Probing black hole accretion tracks, scaling relations and radiative efficiencies from stacked X-ray active galactic nuclei

Francesco Shankar, David H. Weinberg, Christopher Marsden +25

The masses of supermassive black holes at the centres of local galaxies appear to be tightly correlated with the mass and velocity dispersions of their galactic hosts. However, the…

Galaxy sizes and the galaxy-halo connection -- I: the remarkable tightness of the size distributions

Lorenzo Zanisi, Francesco Shankar, Andrea Lapi +6

The mass and structural assembly of galaxies is a matter of intense debate. Current theoretical models predict the existence of a linear relationship between galaxy size () an…

Constraining black hole-galaxy scaling relations from the large-scale clustering of Active Galactic Nuclei and implied mean radiative efficiency

Francesco Shankar, Viola Allevato, Mariangela Bernardi +11

A supermassive black hole has been found at the centre of nearly every galaxy observed with sufficient sensitivity. The masses of these black holes are observed to increase with ei…

Predicting fully self-consistent satellite richness, galaxy growth and starformation rates from the STastical sEmi-Empirical modeL STEEL

Philip J. Grylls, F. Shankar, J. Leja +4

Observational systematics complicate comparisons with theoretical models limiting understanding of galaxy evolution. In particular, different empirical determinations of the stella…

A Statistical Semi-Empirical Model: Satellite galaxies in Groups and Clusters

P. J. Grylls, F. Shankar, L. Zanisi +1

We present STEEL a STatistical sEmi-Empirical modeL designed to probe the distribution of satellite galaxies in groups and clusters. Our fast statistical methodology relies on trac…
