Welcome to the Digital Repository of Indian Institute of Astrophysics
This digital repository of Indian Institute of Astrophysics (IIAP), Bangalore, India is developed to capture, organize disseminate and preserve the research publications of IIAP. It also includes the in-house technical reports and annual reports in addition to various other grey literatures created within the institute.You can search, browse and access full text of these publications from the repository.
This Repository also hosts papers published in Bulletin of the Astronomical Society of India, Volumes 1 to 33, 1973 to 2005. The contents of Vol. 34, 2006 to Current can be accessed from the BASI HOMEPAGE
Archival Collection in Open Access
Indian Institute of Astrophysics traces its origin back to 1786, and the Institute has naturally inherited the library and records of the Madras and Kodaikanal Observatories. This collection of archival records has grown over the years in various formats such as manuscripts, photographs, maps, films, awards, hand-drawn sketches, pictures and instruments.
Narrow line Seyfert 1 (NLSy1) galaxies constitute a class of active galactic nuclei characterized by the full width at half maximum (FWHM) of the Hα broad emission line <2000 km s-1 and the flux ratio of [O III] to Hα <3. Their properties are not well understoo...
Gravitational lensing is brightening of background objects due to deflection of light by foreground sources. Rich clusters of galaxies are very effective lenses because they are centrally concentrated. Such natural Gravitational Telescopes provide us with strongly magnified galaxies at high redsh...
The type II supernovae (SNe) are hydrogen-rich cosmic explosions resulting from the collapse of massive stars. The impetus of studying individual events arises from its cosmological importance and the diverse understanding of the evolution and explosion mechanism of such events. In this ...
Stripped-Envelope Supernovae constitute the sub-class of core-collapse supernovae that strip off their outer hydrogen envelope due to high stellar winds or due to interaction with a binary companion where mass transfer occurs as a result of Roche lobe overflow. We present here the ...
To search for optical variability on a wide range of timescales, we have carried out photometric monitoring of a dozen blazars. CCD magnitudes in B, V, R and I pass-bands were determined for > 10,000f new optical observations from 300 nights made during 2011 – 2016,...
