A new 21-cm absorber identified with an galaxy
Nissim Kanekar, Ramana M. Athreya, Jayaram N. Chengalur
We present Giant Metrewave Radio Telescope (GMRT) observations of redshifted 21-cm absorption from the metal line absorption system towards PKS 1243-072. HI absorption is…
Molecular gas at intermediate redshifts
Nissim Kanekar, Jayaram N Chengalur
We present Giant Metrewave Radio Telescope (GMRT) observations of OH absorption in B3~1504+377 () and PKS 1413+135 (). OH has now been detected in absor…
Variable 21cm absorption at z=0.3127
Nissim Kanekar, Jayaram N Chengalur
We report multi-epoch GMRT HI observations of the z = 0.3127 damped absorber towards the quasar PKS 1127-145, which reveal variability in both the absorption profile and the flux o…
The effects of anti-correlation on gravitational clustering
Nissim Kanekar, T. Padmanabhan
We use non-linear scaling relations (NSRs) to investigate the effects arising from the existence of negative correlations on the evolution of gravitational clustering in an expandi…
Recycling the universe using scalar fields
Nissim Kanekar, Varun Sahni, Yuri Shtanov
We examine the behaviour of a closed oscillating universe filled with a homogeneous scalar field and find that, contrary to naive expectations, such a universe expands to larger vo…
