1306.1842 (Subhashis Roy)

Density of warm ionized gas near the Galactic Center: Low radio frequency observations    [PDF]

Subhashis Roy
We have observed the Galactic Center (GC) region at 0.154 and 0.255 GHz with the GMRT. A total of 62 compact likely extragalactic sources are detected. Their scattering sizes go down linearly with increasing angular distance from the GC up to about 1 deg. The apparent scattering sizes of sources are more than an order of magnitude down than predicted earlier by the NE2001 model of Galactic electron distribution within 359.5 deg < l < 0.5 deg and -0.5 deg View original: http://arxiv.org/abs/1306.1842
