Arecibo-Green Bank-LOFAR Carbon Radio Recombination Line observations toward cold HI Clouds
D. Anish Roshi, W. M. Peters, K. L. Emig +4
We present results from a search for radio recombination lines in three HI self-absorbing (HISA) clouds at 750 MHz and 321 MHz with the Robert C. Byrd Green Bank Telescope (GBT), a…
Long-term meter wavelength variability study of Blazar J1415+1320 using the Ooty Radio Telescope
Sravani Vaddi, P. K. Manoharan, Anish Roshi
J1415+1320 is a well-studied blazar that exhibits strong flux density variability at a wide range of radio frequencies (2.4 230~GHz). In this letter, we present a variability s…
Low frequency observations of linearly polarized structures in the interstellar medium near the south Galactic pole
Emil Lenc, B. M. Gaensler, X. H. Sun +76
We present deep polarimetric observations at 154 MHz with the Murchison Widefield Array (MWA), covering 625 deg^2 centered on RA=0 h, Dec=-27 deg. The sensitivity available in our…
An analysis of the halo and relic radio emission from Abell 3376 from Murchison Widefield Array observations
Lijo T. George, K. S. Dwarakanath, M. Johnston-Hollitt +48
We have carried out multiwavelength observations of the near-by () rich, merging galaxy cluster Abell 3376 with the Murchison Widefield Array (MWA). As a part of the GaLac…
The Spectral Variability of the GHz-Peaked Spectrum Radio Source PKS 1718-649 and a Comparison of Absorption Models
S. J. Tingay, J. -P. Macquart, J. D. Collier +42
Using the new wideband capabilities of the Australia Telescope Compact Array (ATCA), we obtain spectra for PKS 1718-649, a well-known gigahertz-peaked spectrum radio source. The ob…
Serendipitous discovery of a dying Giant Radio Galaxy associated with NGC 1534, using the Murchison Widefield Array
Natasha Hurley-Walker, Melanie Johnston-Hollitt, Ron Ekers +41
Recent observations with the Murchison Widefield Array at 185~MHz have serendipitously unveiled a heretofore unknown giant and relatively nearby () radio galaxy associa…
