On the Hubble diagram of QSOs with cosmological redshifts

Sapre, A. K; Mishra, V. D (Astronomical Society of India, 1996)

In this paper we study the Hubble Diagram of the QSOs whose redshifts are known to be cosmological in nature. These are the QSOs which lie close to bright galaxies and whose redshifts are nearly equal to those of the bright ...
Quasi-stellar objects, galaxies, and the big-bang

Thakur, R. K (Astronomical Society of India, 1997)

This paper has been written in a highly personal vein. It’s a resume of the very modest effort made by the author and his students in understanding some aspects of extragalactic astronomy and astrophysics during the former’s ...
Template-based classification of SDSS-GALEX point sources

Anjum, A; Mousumi Das; Murthy, J; Gudennavar, S. B; Rajesh, G; Bubbly, S. G (Indian Academy of Sciences, 2018-10)

We have classified a sample of 37,492 objects from SDSS into QSOs, galaxies and stars using photometric data over five wave bands (u, g, r, i and z) and UV GALEX data over two wave bands (near-UV and far-UV) based on a ...
