Inflection Points on the Light Curves of Type Ia Supernovae
While the distribution of supernova absolute magnitudes at peak is often investigated, there was no systematic study of absolute light curve behavior... -
Simulations of Solar AO Systems
In this paper, first we compare the two kinds of algorithms that are being used in solar AO systems to sense a distorted wave-front through... -
The Nearby Supernova Factory
The Nearby Supernova Factory is an international project dedicated to the study of the nearby thermonuclear (type Ia) supernovæ. Based upon the NEAT... -
Search for Sub-Stellar Companions Using AO – First Results Obtained with NAOS-CONICA
We present first results of our NAOS-CONICA search for close substellar companions around young nearby stars. This program was started only a few... -
Near-Infrared AO Spectroscopy of Edge-On Protoplanetary Disks with Subaru IRCS
We carried out near infrared (1.4–4.2 μm) AO imaging and spectroscopy of two edge-on protoplanetary disks; HK TauB and HV TauC located in Taurus... -
A Search for Close Companions in Sco OB2
Using adaptive optics we study the binary population in the nearby OB association Scorpius OB2. We present the first results of our near-infrared... -
Adaptive Optics Observations of Stars in Globular Clusters and Nearby Galaxies
Observations of nearby stellar systems with the Canada-France-Hawaii Telescope PUEO Adaptive Optics system, the University of Hawaii HOKUPA’A system... -
NACO Observations of NGC 1068
We present various recent results obtained with adaptive optics systems on the very central region of NGC 1068: Grif long-slit spectroscopy in K band... -
A Near-Infrared Adaptive Optics Imaging Survey of Nearby QSOs
We present the results of a near-IR Adaptive Optics imaging survey of 32 nearby (z<0.325) QSOs with curvature AO systems on the Gemini North and... -
Subaru Deep Field with Adaptive Optics
A deep K′-band (2.12μ m) image of 1′ × 1′ blank sky field (Subaru Deep Field; SDF) taken with Subaru Adaptive Optics System (AO) is presented. The... -
Adaptive Optics Science with the MMT Adaptive Secondary: Mid-IR AO Imaging of the Post-AGB Star AC Her
The world’s first adaptive secondary has been commissioned at the 6.5m MMT. Early science results suggests that it is unique and highly productive.... -
One Year of NACO Operations
The first ESO adaptive optics system instrument, NACO, installed at the VLT has been offered to the astronomical community and used on a regular... -
The Construction of X-ray Cluster Surveys and Their Spatial Analysis
The construction of X-ray cluster surveys is described. As an example the selection processes applied to the REFLEX survey and first results of an... -
The 2dF QSO Redshift Survey - 10K@2K!
With $\approx$ 10000 QSO redshifts, the 2dF QSO Redshift Survey... -
Clustering of X-Ray Selected AGN
The analysis of the spatial clustering of the brightest X-ray selected AGN from the ROSAT All Sky Survey is presented. A weak correlation signal at a... -
Strong Constraints on Cosmology from Galaxy Clusters
In this work we show how galaxy clusters can be used to discriminate among different cosmological models. We have used available X-ray & optical... -
Large-Scale Distribution and Spectral Properties of Galaxies in the Shapley Concentration
We present the results of a redshift survey of both cluster and intercluster galaxies in the central part of the Shapley Concentration, the richest... -
FORCE: FORtran for Cosmic Errors
We review the theory of cosmic errors we have recently developed for count-in-cells statistics. The corresponding FORCE package provides a simple and... -
Relating Galaxy Cluster X-Ray Luminosities to Gravitational Masses in Wide-Angle Surveys
The cosmologically most important cluster parameter is its gravitational mass. In order to constrain cosmological models of structure formation by... -
Automated Classification Techniques for Large Spectroscopic Surveys
With the onset of large, systematically selected spectroscopic surveys we have the opportunity to understand the distribution and evolution of...
