(will be inserted by hand later) A difference boosting neural network for automated classification
Automated Data Analysis in Astronomy, xx-xx Bayesian Approach for Star- Galaxy Classification (2007)
Ninan Sajeeth Philip, Ajit Kernbhavi, Yogesh Wadadekar, K. Babu Joseph
Abstract. This paper describes the possibility of using a difference boosting neural network (DBNN) instead of a multilayer feed forward neural network in Bertin's SExtractor package (SEx) for...
Lenticular Galaxy Formation - Possible Luminosity Dependence (2007)
Barway, Sudhanshu, Kembhavi, Ajit, Wadadekar, Yogesh, Ravikumar, C. D., Mayya, Y. D.
We investigate the correlation between the bulge effective radius (r_e) and disk scale length (r_d), in the near-infrared K band for lenticular galaxies in the field and in clusters. We find markedly...
Faint U-Band Dropouts in the WFPC2 Parallels of the Hubble Ultra Deep Field (2006)
Wadadekar, Yogesh, Casertano, Stefano, De Mello, Duilia
We combine data from the extremely deep Hubble Space Telescope $U$ (F300W) image obtained using WFPC2 as part of the parallel observations of the Hubble Ultra Deep Field campaign, with $BVi$ images...
