Morphological Studies of the SWIRE Galaxy Population in the UGC 10214 HST/ACS field
E. Hatziminaoglou, P. Cassata, G. Rodighiero +16
We present results of a morphological analysis of a small subset of the Spitzer Wide-area InfraRed Extragalactic survey (SWIRE) galaxy population. The analysis is based on public A…
Sloan Digital Sky Survey Quasars in the SWIRE ELAIS N1 Field: Properties and Spectral Energy Distributions
E. Hatziminaoglou, I. Perez-Fournon, M. Polletta +16
We present a mid-infrared analysis of 35 quasars with spectroscopic redshifts selected from the Spitzer Wide-area InfraRed Extragalactic Survey (SWIRE). We discuss their optical an…
QSO Photometric Redshift estimation for the XMM-Newton/2dF Survey
S. Kitsionas, E. Hatziminaoglou, I. Georgantopoulos +2
The technique of estimating redshifts using photometric rather than spectroscopic observations has recently received great attention due to its simplicity and the accuracy of the r…
ESO Imaging Survey. Deep Public Survey: Infrared Data for the Chandra Deep Field South
B. Vandame, L. F. Olsen, H. E. Jorgensen +12
This paper presents new J and Ks near-infrared data obtained from observations of the Chandra Deep Field South (CDF-S) conducted at the ESO 3.5m New Technology Telescope (NTT). The…
Hierarchical Clustering and Active Galaxies
E. Hatziminaoglou, G. Mathez, A. Manrique
The growth of Super Massive Black Holes and the parallel development of activity in galactic nuclei are implemented in an analytic code of hierarchical clustering. The evolution of…
Quasar Candidate Multicolor Selection Technique: a different approach
E. Hatziminaoglou, G. Mathez, R. Pello
We present a quasar candidate identification technique based on multicolor photometry. The traditional multi-dimensional method (2 N dimensions, where N is the number of t…
