Probing the co-evolution of SMBHs and their hosts from scaling relations pairwise residuals: dominance of stellar velocity dispersion and host halo mass
Francesco Shankar, Mariangela Bernardi, Daniel Roberts +17
The correlations between Supermassive Black Holes (SMBHs) and their host galaxies still defy our understanding from both the observational and theoretical perspectives. Here we per…
Coincidence between morphology and star-formation activity through cosmic time: the impact of the bulge growth
Paola Dimauro, Emanuele Daddi, Francesco Shankar +10
The origin of the quenching in galaxies is still highly debated. Different scenarios and processes are proposed. We use multi-band (400-1600 nm) bulge-disc decompositions of massiv…
The role of scatter and satellites in shaping the large-scale clustering of X-ray AGN as a function of host galaxy stellar mass
Akke Viitanen, Viola Allevato, Alexis Finoguenov +2
The co-evolution between central supermassive black holes (BH), their host galaxies, and dark matter halos is still a matter of intense debate. Present theoretical models suffer fr…
The size function of massive satellites from the and relations: constraining the role of environment
Lorenzo Zanisi, Francesco Shankar, Mariangela Bernardi +2
In previous work we showed that a semi-empirical model in which galaxies in host dark matter haloes are assigned stellar masses via a stellar mass-halo mass (SMHM) relation and siz…
The evolution of compact massive quiescent and starforming galaxies derived from the and relations
L. Zanisi, F. Shankar, H. Fu +12
The mean size ( effective radius ) of Massive Galaxies (MGs, ) is observed to increase steadily with cosmic time. It is still unclear whether th…
The case for the fundamental - relation
Christopher Marsden, Francesco Shankar, Michele Ginolfi +1
Strong scaling relations between host galaxy properties (such as stellar mass, bulge mass, luminosity, effective radius etc) and their nuclear supermassive black hole's mass point…
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…
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…
The structural properties of classical bulges and discs from z~2
Paola Dimauro, Marc Huertas-Company, Emanuele Daddi +19
We study the rest-frame optical mass-size relation of bulges and discs from z~2 to z~0 for a complete sample of massive galaxies in the CANDELS fields using 2 component Sérsic mode…
Black hole scaling relations of active and quiescent galaxies: Addressing selection effects and constraining virial factors
Francesco Shankar, Mariangela Bernardi, Kayleigh Richardson +9
Local samples of quiescent galaxies with dynamically measured black hole masses (Mbh) may suffer from an angular resolution-related selection effect, which could bias the observed…
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…
A catalog of polychromatic bulge-disk decompositions of ~ 17.600 galaxies in CANDELS
Paola Dimauro, Marc Huertas-Company, Emanuele Daddi +20
Understanding how bulges grow in galaxies is critical step towards unveiling the link between galaxy morphology and star-formation. To do so, it is necessary to decompose large sam…
NGC 1275: an outlier of the black hole-host scaling relations
Eleonora Sani, Federica Ricci, Fabio La Franca +7
The active galaxy NGC 1275 lies at the center of the Perseus cluster of galaxies, being an archetypal BH-galaxy system that is supposed to fit well with the M_BH-host scaling relat…
The Dramatic Size and Kinematic Evolution of Massive Early-Type Galaxies
