A simulation-calibrated limit on the H i power spectrum from the GMRT Epoch of Reionization experiment
The Giant Metrewave Radio Telescope Epoch of Reionization experiment is an ongoing effort to measure the power spectrum from neutral hydrogen at high redshift. We have previously reported an upper
Refractive interstellar scintillation in pulsar dynamic spectra
The evolution of the dynamic spectra of eight pulsars over 16 months is reported. Observations were made at Jodrell Bank at 408 MHz from 1984 September to 1986 January. The changing form of the
Understanding the Radio Emission Geometry of PSR B0329+54
We have analyzed high-quality single-pulse data of PSR B0329+54 at 325 and 606 MHz to study the structure of the emission beam. Using the "window-threshold technique," which is suitable for detecting
Radio Searches of Fermi LAT Sources and Blind Search Pulsars: The Fermi Pulsar Search Consortium
We present a summary of the Fermi Pulsar Search Consortium (PSC), an international collaboration of radio astronomers and members of the Large Area Telescope (LAT) collaboration, whose goal is to
The GMRT Epoch of Reionization experiment: a new upper limit on the neutral hydrogen power spectrum at z≈ 8.6
We present a new upper limit to the 21cm power spectrum during the Epoch of Reionization (EoR) which constrains reionization models with an unheated IGM. The GMRT-EoR experiment is an ongoing effort
The discovery of PSR J1833–1034: the pulsar associated with the supernova remnant G21.5–0.9
We report the discovery of a young pulsar associated with the supernova remnant G21.5–0.9, using the Giant Metrewave Radio Telescope (GMRT) located near Pune, India. Discovered at a frequency of 610
Multifrequency integrated profiles of pulsars
We have observed a total of 67 pulsars at five frequencies ranging from 243 to 3100 MHz. Observations at the lower frequencies were made at the Giant Metre-Wave Telescope in India and those at higher
Observations of four glitches in the young pulsar J1833−1034 and study of its glitch activity
We present the results from timing observations with the GMRT of the young pulsar J1833 1034, in the galactic supernova remnant G21.5 0.9. We detect the presence of 4 glitches in this pulsar over a
