A statistical analysis is made on the correlation between solar proton events with energies > 10Mev and solar radio bursts during the four-year period from 1997
We calculate photometricredshifts from the Sloan Digital Sky SurveyData Release 2 (SDSS DR2) Galaxy Sample using artificial neural networks (ANNs). Different in
We present a case study of the relevance of the radially pulsational instability of a two-temperature accretion disk around a neutron star to anomalous X-ray pu
