Jan Veth's paintings of Jacobus Kapteyn
Pieter C. van der Kruit
Jacobus C. Kapteyn is regarded as one of the coryfees of the University of Groningen. Part of his legacy is two paintings of him by Dutch painter Jan Pieter Veth. One, showing him…
Pannekoek's Galaxy
Pieter C. van der Kruit
Antonie (Anton) Pannekoek (1873-1960) is remembered as one of the initiators of the field of stellar atmospheres. A second part of his research concerned Galactic astronomy. He was…
Pieter Johannes van Rhijn, Kapteyn's Astronomical Laboratory and the Plan of Selected Areas
P. C. van der Kruit
In this contribution I discuss the Kapteyn Astronomical Laboratory during the period of Pieter Johannes van Rhijn's directorate, which lasted from 1921 to 1957. It had developed un…
The Shape of Dark Matter Haloes IV. The Structure of Stellar Discs in Edge-on Galaxies
S. P. C. Peters, G. de Geyter, P. C. van der Kruit +1
We present optical and near-infrared archival observations of eight edge-on galaxies. These observations are used to model the stellar content of each galaxy using the FitSKIRT sof…
The Shape of Dark Matter Haloes III. Kinematics and Structure of the HI disc
S. P. C. Peters, P. C. van der Kruit, R. J. Allen +1
We present a new strategy for fitting the structure and kinematics of the HI in edge-on galaxies using a fit to the terminal-velocity channel maps of a HI data cube. The strategy c…
The Shape of Dark Matter Haloes II. The Galactus HI Modelling & Fitting Tool
S. P. C. Peters, P. C. van der Kruit, R. J. Allen +1
We present a new HI modelling tool called \textsc{Galactus}. The program has been designed to perform automated fits of disc-galaxy models to observations. It includes a treatment…
The Shape of Dark Matter Haloes, V. Analysis of observations of edge-on galaxies
S. P. C. Peters, P. C. van der Kruit, R. J. Allen +1
In the previous papers in this series, we have measured the stellar and \hi content in a sample of edge-on galaxies. In the present paper, we perform a simultaneous rotation curve…
Lessons from the Milky Way: the Kapteyn Universe
P. C. van der Kruit
Jacobus Cornelius Kapteyn (1851-1922) presented a model for the distribution of stars in space together with a dynamical interpretation in terms of an equilibrium between the gravi…
The Shape of Dark Matter Haloes, I. HI Observations of Edge-on Galaxies
S. P. C. Peters, P. C. van der Kruit, R. J. Allen +1
We present neutral hydrogen observations for a sample of eight nearby, late-type, edge-on galaxies. All of the galaxies have been well resolved in the radial direction, while six h…
Atomic Hydrogen produced in M33 Photodissociation Regions
J. S. Heiner, R. J. Allen, P. C. van der Kruit
We derive total (atomic + molecular) hydrogen densities in giant molecular clouds (GMCs) in the nearby spiral galaxy M33 using a method that views the atomic hydrogen near regions…
Galaxy Disks
P. C. van der Kruit, K. C. Freeman
The formation and evolution of galactic disks is particularly important for understanding how galaxies form and evolve, and the cause of the variety in which they appear to us. Ong…
A new method for obtaining the star formation law in galaxies
J. S. Heiner, R. J. Allen, P. C. van der Kruit
We present a new observational method to evaluate the star formation law as formulated by Schmidt: the power-law expression assumed to relate the rate of star formation in a volume…
Structure, mass and stability of galactic disks
P. C. van der Kruit
In this review I concentrate on three areas related to structure of disks in spiral galaxies. First I will review the work on structure, kinematics and dynamics of stellar disks. N…
The dark matter halo shape of edge-on disk galaxies - I. HI observations
J. C. O'Brien, K. C. Freeman, P. C. van der Kruit +1
This is the first paper of a series in which we will attempt to put constraints on the flattening of dark halos in disk galaxies. We observe for this purpose the HI in edge-on gala…
The dark matter halo shape of edge-on disk galaxies - III. Modelling the HI observations: results
J. C. O'Brien, K. C. Freeman, P. C. van der Kruit
This is the third paper in a series in which we attempt to put constraints on the flattening of dark halos in disk galaxies. For this purpose we need to analyse the observed XV dia…
The dark matter halo shape of edge-on disk galaxies - II. Modelling the HI observations: methods
J. C. O'Brien, K. C. Freeman, P. C. van der Kruit
This is the second paper of a series in which we attempt to put constraints on the flattening of dark halos in disk galaxies. For this purpose, we observe the HI in edge-on galaxie…
The dark matter halo shape of edge-on disk galaxies - IV. UGC 7321
J. C. O'Brien, K. C. Freeman, P. C. van der Kruit
This is the fourth paper in a series in which we attempt to put constraints on the flattening of dark halos in disk galaxies. We observed for this purpose the HI in edge-on galaxie…
Flattening and truncation of stellar discs in edge-on spiral galaxies
Michiel Kregel, Pieter C. van der Kruit, Richard de Grijs
We analyse the global structure of the old stellar discs in 34 edge-on spiral galaxies. The radial and vertical exponential scale parameters of the discs are obtained by applying a…
