| Abstract | The morphological evolution of galaxies as a function of redshift is studied using two quantitative structural parameters R η (galaxy radius) and χ (high spatial frequency power). A direct comparison is made between nearby and distant (0.2 < z < 1) galaxies in the Hubble Deep Field (HDF) by following the 4500 Å rest-frame wavelength range. Few if any of the HDF galaxies are similar in size and in star formation rate to dwarf galaxies such as NGC 4449 and NGC 1569. The majority of HDF galaxies have sizes comparable to local giant galaxies and are slightly more lumpy than normal galaxies. Dwarf galaxies undergoing high rates of star formation are unlikely to be local counterparts of the high-redshift population of galaxies. Based exclusively on the structural parameters studied here, giant galaxies undergoing intensive rates of star formation (giant star-burst galaxies) are possible local counterparts of the high-redshift irregular galaxies. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
