The colours of BL Lac objects: a new approach to their classification
galaxies:active:BL Lac objects
font style='font-size:12px;'>

We selected a sample of 437 BL Lac objects, taken from the RomaBZCat catalogue, for which spectroscopic information and SDSS photometry is available. We propose a new classification of BL Lacs in whic...
Spectrophotometric Redshifts. A New Approach to the Reduction of Noisy Spectra and its Application to GRB090423
Cosmology and Extragalactic Astrophysics (astro-ph.CO)

2010/12/27
We have developed a new method, close in philosophy to the photometric redshift technique, which can be applied to spectral data of very low signal-to-noise ratio. Using it we intend to measure redshi...

A NEW APPROACH TO THE ESTIMATION OF THE DISPERSION COMPONENTS
DISPERSION COMPONENTS unknown X iterative algorihm
font style='font-size:12px;'>
2009/3/31
A new method to calculate simultaneosly both the unknown X
and the components of the dispersion (results of measurement) is developed. An
improved iterative algorihm is used.
