Not Color Blind: Using Multiband Photometry to Classify Supernovae

Large numbers of supernovae (SNe) have been discovered in recent years, and many more will be found in the near future. Once discovered, further study of a SN and its possible use as an astronomical tool (e.g., as a distance estimator) require knowledge of the SN type. Current classification methods rely almost solely on the analysis of SN spectra to determine their type. However, spectroscopy ...

Mosaic wide-field multi-band photometry

We present Johnson UBV , and Kron-Cousins I photometry for about 60,000 stars in a region of 44 × 33 arcmin2 centered on the Galactic globular cluster (GGC) NGC 2808. The central r < 100 arcsec region has been mapped also in the F218W, F439W, and F555W bands with the HST WFPC2 camera. Overall, we cover a field which extends from the center to about 1.7 tidal radii. Photometric calibration has b...

Simultaneous time - series spectroscopy and multi - band photometry of the sdBV PG 1605 + 072 ⋆

We present time-series spectroscopy and multi-band photometry of the sdBV PG1605+072 carried out simultaneously at the Calar Alto 2.2m and 3.5m telescopes. The periodogram analysis of the radial velocity curves reveals three frequencies at 2.078, 2.756, and 1.985 mHz for Hβ and at 2.076, 2.753, and 1.978 mHz for Hγ . The corresponding radial velocity amplitudes are 12.7, 8.0, and 7.9 km/s for H...

Using DAML+OIL to classify intrusive behaviours

We have produced an ontology specifying a model of computer attack. Our ontology is based upon an analysis of over 4000 classes of computer intrusions and their corresponding attack strategies and is categorised according to system component targeted, means of attack, consequence of attack and location of attacker. We argue that any taxonomic characteristics used to define a computer attack be ...
