A radio study of the superwind galaxy NGC1482

Ananda Hota, D. J. Saikia

We present multifrequency radio continuum as well as HI observations of the superwind galaxy NGC1482, with both the GMRT and the VLA. This galaxy has a remarkable hourglass-shaped…

Intra-night Optical Variability of BL Lacs, Radio-Quiet Quasars and Radio-Loud Quasars

C. S. Stalin, A. C. Gupta, Gopal-Krishna +2

We report optical monitoring observations of 20 high-luminosity AGN, 12 of which are radio-quiet quasars (RQQs). Intra-night optical variability (INOV) was detected for 13 of the 2…

Radio sources at low Galactic latitudes

D. J. Saikia, P. Thomasson, S. Roy +2

We present high-resolution radio observations of a sample of 65 radio sources at low Galactic latitudes. The sources were all observed at 5 GHz with the Very Large Array A-array. M…

FUSE search for 10^5-10^6 K gas in the rich clusters of galaxies Abell 2029 and Abell 3112

A. Lecavelier des Etangs, Gopal-Krishna, F. Durret

Recent Chandra and XMM X-ray observations of rich clusters of galaxies have shown that the amount of hot gas which is cooling below ~1 keV is generally more modest than previous es…

Inflationary Cosmology and Quantization Ambiguities in Semi-Classical Loop Quantum Gravity

Martin Bojowald, James E. Lidsey, David J. Mulryne +2

In loop quantum gravity, modifications to the geometrical density cause a self-interacting scalar field to accelerate away from a minimum of its potential. In principle, this mecha…
