The Darwin Space Interferometer
Darwin is a mid-IR(5-30 micron) interferometry observatory with baselines greater than 50 metres. As a long-duration general purpose observatory, ESA... -
Observations of Cygnus X-3 in Quiescence in the $2.4 - 12 \mu$ m Range with ISO
We present mid-infrared spectrophotometric and imaging photometric results obtained with ISO on the peculiar X-ray binary Cygnus X-3. The... -
Effects of Anisotropy on the Central Dark Mass in NGC 3115. New Results from Integral Field Spectroscopy
We report new results on the stellar kinematics and the mass distribution of the galaxy NGC 3115 based on NIR integral field spectroscopic data.... -
SINFONI - Galaxy Dynamics at $0^{\prime\prime}\hspace{-0.2cm}.05$ Resolution with the VLT
The SINFONI integral field spectrometer for the VLT will provide nearinfrared spatially resolved spectra at spatial resolutions close to the... -
Simultaneous Infrared and mm- Wave Observations of Disc Ejection Events in GRS 1915+105
We have observed in the Galactic X-ray source GRS 1915+105 some of the brightest 20-min quasi-periodic oscillations yet seen, simultaneously at... -
Molecular Gas in Nuclei of the Seyfert Galaxies NGC3227 and NGC1068
New subarcsecond data on NGC 3227 and NGC 1068 obtained with the Plateau de Bure millimeter interferometry indicate large enclosed masses and the... -
X-Ray Spectra of Neutron Stars vs. Black Holes
This paper gives an overview of the observed X-ray spectra of lowmass X-ray binaries containing a weakly-magnetized neutron star (NS-LMXRB) and those... -
Gravitational Lens Diagnosis of Quasar Accretion Disk
We present simulated microlensing light curves of a quasar accretion disk using two canonical accretion disk models. Furthermore, we investigate the... -
Galaxy Masses: Disks and Their Halos
I review what we currently do and do not know about the masses of disk galaxies and their dark matter halos. The prognosis for disks is good: the... -
Luminosities of Radio-Loud Active Galaxies
We investigate the host galaxy luminosities of three different samples of radio loud active nuclei at z<0.5 including BL Lac Objects (BLLs), Radio... -
Probing the Evolution of Massive Galaxies with the K20 Survey
The motivations and the status of the K20 survey are presented. The first results on the evolution of massive galaxies and the comparison with the... -
The Evolution of Galaxy Mass in Hierarchical Models
Advances in extragalactic astronomy have prompted the development of increasingly realistic models which aim to describe the formation and evolution... -
Studying the Dynamics of Star Forming and IR Luminous Galaxies with Infrared Spectroscopy
With the advent of efficient near-IR spectrometers on 10m-class telescopes, exploiting the new generation of low readout noise, large format... -
What Does the Local Black Hole Mass Distribution Tell Us About the Evolution of the Quasar Luminosity Function?
We present a robust method to derive the duty cycle of QSO activity based on the empirical QSO luminosity function and on the present-day linear... -
Spheroidal Galaxies/QSOs Connection
In view of the extensive evidence of a tight inter-relationship between spheroidal galaxies (and galactic bulges) and massive black holes hosted at... -
The Mass of Radio Galaxies from Low to High Redshift
Using a new radio sample, 6C* designed to find radio galaxies at z > 4 along with the complete 3CRR and 6CE sample we extend the radio galaxy K-z... -
Estimating the Mass of Local Disk Galaxies from the NIR Luminosity
The relation between the dynamical mass ( $\propto V_{max}^2 \times r_{opt}$... -
Clustering at High Redshift
The addition of deep near infrared images to the database provided by the HDF WFPC2 is essential to monitor the SEDs of the objects on a wide... -
Detection of CDM Substructure
The properties of multiple image gravitational lenses require a fractional surface mass density in satellites of f... -
Lens Galaxies vs. CDM
By directly probing mass distributions, gravitational lensing offers several new tests of the CDM paradigm. Lens statistics place upper limits on the...
