Intermediate-mass black holes in nuclear star clusters
ELT/HARMONI
Simulating the ELT observation, using high-resolution imaging and spectroscopy and the proximity of our low-mass early-type galaxy sample, I examine in detail their NSCs morphology, composition, kinematics, and dynamical masses to shed a light on their formation origins either gas in situ or stellar migration.
The formation and co-evolution of central massive black holes and their host galaxies
ELT/HARMONI + ALMA
Studying galaxy and massive black hole’s evolution by MBH - σ correlation. Scaling relations between central black hole mass and host galaxy properties, e.g., the bulge mass component and bulge velocity dispersion of stars, hint to a joint evolution of black holes and galaxies. Estimating the dynamical mass of black holes and their host galaxies at different redshifts is fundamental to establish their growth scenarios over the cosmic time.
Ultra-massive black holes at the highest galactic-mass ladder
ELT/HARMONI + ALMA
There are evidences of most massive galaxies show that the central black hole mass positive outliers from the Mbh-sigma or Mbh-Lk relation. It argues that they assemble their matter, changing from a sequence of bulge growth to dry-merger growth. The expectation that BH will increase their mass through coalescence with other similar size black holes. Obviously, the most massive galaxies is the key for our understanding about galaxy evolution and in particular how ultramassive black holes can form
