Massive star formation in the central regions of spiral galaxies
J. H. Knapen, L. M. Mazzuca, T. Boeker +4
Context: The morphology of massive star formation in the central regions of galaxies is an important tracer of the dynamical processes that govern the evolution of disk, bulge, and…
AM 1934-563: A giant spiral polar-ring galaxy in a triplet
V. Reshetnikov, F. Bournaud, F. Combes +2
We have observed the emission-line kinematics and photometry of a southern triplet of galaxies. The triplet contains a giant spiral galaxy AM 1934-563 which optical structure resem…
The life-time of galactic bars: central mass concentrations and gravity torques
F. Bournaud, F. Combes, B. Semelin
Bars in gas-rich spiral galaxies are short-lived. They drive gas inflows through their gravity torques, and at the same time self-regulate their strength. Their robustness has been…
Polar ring galaxies and warps
F. Combes
Polar ring galaxies, where matter is in equilibrium in perpendicular orbits around spiral galaxies, are ideal objects to probe the 3D shapes of dark matter halos. The conditions to…
ALMA and Cosmology
F. Combes
ALMA is a privileged instrument to tackle high redshift galaxies, due to the negative K-correction in the millimeter domain. Many dusty star-forming galaxies, invisible in the opti…
The Galaxy in the cosmological context
F. Combes
A new view on our Galaxy has recently emerged, with large consequences on its formation scenarios. Not only new dwarf satellites have been detected, still orbiting and tidally disr…
New CO observations and simulations of the NGC 4438/NGC 4435 system
B. Vollmer, J Braine, F. Combes +1
NGC 4438 is a highly perturbed spiral with a stellar tidal tail and extraplanar molecular gas, now very HI deficient, crossing the center of the Virgo cluster at high speed. Variou…
Secular Evolution of Galaxies
Francoise Combes
In current CDM galaxy formation scenarios, at least three physical phenomena could contribute to the mass assembly: monolithic collapse, hierarchical mergers and more quiescent…
New multi-zoom method for N-body simulations: application to galaxy growth by accretion
B. Semelin, F. Combes
In this work we focus on the properties of accretion onto galaxies. Through numerical simulations we investigate the geometrical properties of accretion. To span the scale range re…
Formation and Evolution of Supermassive Black Holes
Francoise Combes
The correlation between the mass of supermassive black holes in galaxy nuclei and the mass of the galaxy spheroids or bulges (or more precisely their central velocity dispersion),…
Spectral and morphological properties of quasar hosts in SPH simulations of AGN feeding by mergers
A. Cattaneo, F. Combes, S. Colombi +2
We present a method for generating virtual observations from smoothed-particle-hydrodynamics (SPH) simulations. This method includes stellar population synthesis models and the rep…
Detections of CO in Late-Type, Low Surface Brightness Spiral Galaxies
Lynn D. Matthews, Yu Gao, Juan M. Uson +1
Using the IRAM 30-m telescope, we have obtained 12CO J=1-0 and 2-1 spectral line observations toward the nuclear regions of 15 edge-on, low surface brightness (LSB) spiral galaxies…
