Mining the Local Universe: the QSO Space Density
We present progress results of a new survey for bright QSOs (V < 14.5, R < 15.4, B J... -
Field Galaxy Evolution from the Munich Near-Infrared Cluster Survey (MUNICS)
The Munich Near-IR Cluster Survey (MUNICS) is a K’-selected survey covering 1 square degree in the K’ and J near-infrared bands with complementary... -
Nonlinear Peculiar-Velocity Analysis and PCA
We allow for nonlinear effects in the likelihood analysis of peculiar velocities, and obtain... -
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... -
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... -
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... -
Near-Infrared Integral Field Spectroscopy of Damped Lyman- $\alpha$ Systems
We assess the feasibility of detecting star formation in damped Lyman- $\alpha$... -
Fast Algorithms and Efficient Statistics: N-Point Correlation Functions
We present here a new algorithm for the fast computation of N-Point correlation functions in large astronomical data sets. The algorithm is based on... -
Noise Estimation in CMB Time-Streams and Fast Iterative Map-Making
We describe here an iterative method for jointly estimating the noise power spectrum from a CMB experiment’s time-ordered data, together with the... -
Massive Variability Searches: the Past, Present and Future
Many decades ago a search for variable stars was one of the main areas of astrophysical research. Such searches, conducted with CCD detectors rather... -
NIR Visibility Function of Emission Lines with the Galileo OH Subtracted Spectrograph
We study here the visibility function of emission lines expected for GOHSS. This spectrograph will accomplish, on spectra observed at resolution... -
Fast Hough Transform for Robust Detection of Satellite Tracks
Satellite tracks are frequently observed on images obtained with wide-field imagers and relative long exposure times. In order to prevent false... -
Mining the Thermal SZ Effect with a Speedy Pixon Algorithm
A Speedy Pixon Algorithm for image reconstruction is applied. Galaxy clusters are extracted from multi-wavelength microwave sky maps using the... -
Blind Source Separation of Multispectral Astronomical Images
Multispectral images lead to classify pixels, but often with the drawback that each pixel value is the result of a combination of different sources.... -
Extracting Knowledge from Very Large Datasets in a Multi-Wavelength Context
The ability to extract knowledge from very large data catalogues resulting from sky surveys or from deep wide fields, observed at various wavelength... -
OPTICON and the Virtual Observatory
The challenges of multi-wavelength astrophysics require new outlooks from those appropriate to traditional astronomy. The next generation of research... -
Mining the CDS Collection: A Learning Experience
The experiences gained as a result of the CDS/ESO Datamining project are described in this paper as well as a brief outline of the tools developed... -
DEEP: Pre-DEIMOS Surveys to $I \sim 24$ of Galaxy Evolution and Kinematics
DEEP is a two-phase program designed to undertake spectroscopic surveys of faint field galaxies with the Keck Telescopes. The scientific goals... -
Constraining Models of Galaxy Formation with Deep Multicolor Galaxy Surveys
We present a comparison between the observed properties of high redshift galaxies, as they result from the analysis of deep multicolor imaging... -
Modeling Faint Morphological Number Counts
We revisit our recent results concerning comparisons of magnitude and photometric redshift data from the Hubble Deep Fields to statistical...
