Detecting pulsar polarization below 100 MHz with the Long Wavelength Array

Gbt Polarization Observations of 100 Pulsars at 774 Mhz

We report on polarimetric observations of 100 pulsars centered on 774 MHz, made using the Green Bank Telescope (GBT), presenting their polarization profiles and polarized flux densities and comparing them with previous observations when possible. For 67 pulsars, these are the first such measurements made. Polarization profiles of 8 millisecond pulsars in our sample show wide profiles and flat p...

Flaring Stars and the Long Wavelength Array

Coherent emission appears to be a common phenomenon on radio-active late-type stars. Solar radio flare emissions below 3 GHz are rich and varied, arising from coherent processes in the upper solar atmosphere (Dulk 1985; Isliker & Benz 1994). Studies of decimetric radio emission from M dwarf flare stars have led to discovery of high brightness temperature, highly circularly polarized bursts (Bas...

Giant “Pulsar” Studies with the Compact Array

I present recent results from work at the ATCA on stellar pulsars. Five objects, including the Ap star CU Vir and a set of ultracool dwarfs have been found to emit periodic radio pulses that are up to 100% circularly polarised. I followed up a selection of these with the ATCA, more recently with the Compact Array Broadband Backend. Initial results show intriguing wide-band properties. I hope to...
