A new view on the ISM of galaxies: far-infrared and submillimetre spectroscopy with Herschel (2009)

Baes, Maarten, Madden, Suzanne C., Wilson, Christine D., Lundgren, Andreas A., De Breuck, Carlos

The FIR/submm window is amongst the least explored spectral regions of the electromagnetic spectrum. It is, however, a key to study the general properties of the interstellar medium of galaxies, as...

Exact potential-density pairs for flattened dark haloes (2008)

Baes, Maarten

Cosmological simulations suggest that dark matter haloes are not spherical, but typically moderately to strongly triaxial systems. We investigate methods to convert spherical potential-density pairs...

Smart detectors for Monte Carlo radiative transfer (2008)

Baes, Maarten

Many optimization techniques have been invented to reduce the noise that is inherent in Monte Carlo radiative transfer simulations. As the typical detectors used in Monte Carlo simulations do not...

Black hole mass measurements using ionized gas discs: systematic dust effects (2008)

Using detailed Monte Carlo radiative transfer simulations in realistic models for galactic nuclei, we investigate the influence of interstellar dust in ionized gas discs on the rotation curves and...

The dynamical structure of dark matter halos with universal properties (2008)

Van Hese, Emmanuel, Baes, Maarten, Dejonghe, Herwig

$N$-body simulations have unveiled several apparently universal properties of dark matter halos, including a cusped density profile, a power-law pseudo phase-space density $\rho/\sigma_r^3$, and a...

Dynamical models linking BH masses and DM content (2004)

Buyle, Pieter, Dejonghe, Herwig, Baes, Maarten

We investigate the relation between the dark matter distribution of galaxies and their central supermassive black holes which is suggested by the v_c-sigma relation. Since early-type galaxies appear...

The dynamical structure of isotropic spherical galaxies with a central black hole (2004)

Baes, Maarten, Dejonghe, Herwig, Buyle, Pieter

We discuss the kinematical structure of a two-parameter family of isotropic models with a central black hole. The family contains the slope of the central density cusp and the relative black hole...

The HI Detection of Low Column Density Clouds and Galaxies (2004)

Linder, Suzanne M., Minchin, Robert F., Davies, Jonathan I., Baes, Maarten, Evans, Rhodri, Roberts, Sarah, ...

The HIDEEP survey (Minchin et al. 2003) was done in an attempt to find objects having low inferred neutral hydrogen column densities, yet they found a distribution which was strongly peaked at...

Observational evidence for a connection between SMBHs and dark matter haloes (2004)

Baes, Maarten, Dejonghe, Herwig, Buyle, Pieter, Ferrarese, Laura, Gentile, Gianfranco

We investigate the relation between circular velocity vc and bulge velocity dispersion sigma in spiral galaxies, based on literature data and new spectroscopic observations. We find a strong, nearly...

A completely analytical family of dynamical models for spherical galaxies and bulges with a central black hole (2004)

Baes, Maarten, Dejonghe, Herwig

We present a family of spherical models for elliptical galaxies and bulges consisting of a stellar component and a central black hole. All models in this family share the same stellar density...

Tracing the relation between black holes and dark haloes (2003)
