E.; Anish Roshi, D.; Salah, Joseph E.; Sault, Robert J.; Udaya Shankar, N.; Srivani, K. S.; Stevens, Jamie B.; Tingay, Steven J.; Wayth, Randall B.; Waterson, Mark; Webster, Rachel L.; Whitney, Alan R.; Williams, Andrew J.; Wyithe, J. S. (2012)
    The Murchison Widefield Array (MWA) is a new low-frequency, wide-field-of-view radio interferometer under development at the Murchison Radio-astronomy Observatory in Western Australia. We have used a 32 element MWA prototype ...
  • Magnetic Field Strengths in Photodissociation Regions 
    Balser, Dana S.; Anish Roshi, D.; Jeyakumar, S.; Bania, T. M.; Montet, Benjamin T.; Shitanishi, J. A. (2016)
    We measure carbon radio recombination line (RRL) emission at 5.3 {{GHz}} toward four H ii regions with the Green Bank Telescope to determine the magnetic field strength in the photodissociation region (PDR) that surrounds ...
  • A Study of Fundamental Limitations to Statistical Detection of Redshifted H I from the Epoch of Reionization 
    Thyagarajan, Nithyanandan; Udaya Shankar, N.; Subrahmanyan, Ravi; Arcus, Wayne; Bernardi, Gianni; Bowman, Judd D.; Briggs, Frank; Bunton, John D.; Cappallo, Roger J.; Corey, Brian E.; deSouza, Ludi; Emrich, David; Gaensler, Bryan M.; Goeke, Robert F.; Greenhill, Lincoln J.; Hazelton, Bryna J.; Herne, David; Hewitt, Jacqueline N.; Johnston-Hollitt, Melanie; Kaplan, David L.; Kasper, Justin C.; Kincaid, Barton B.; Koenig, Ronald; Kratzenberg, Eric; Lonsdale, Colin J.; Lynch, Mervyn J.; McWhirter, S. Russell; Mitchell, Daniel A.; Morales, Miguel F.; Morgan, Edward H.; Oberoi, Divya; Ord, Stephen M.; Pathikulangara, Joseph; Remillard, Ronald A.; Rogers, Alan E. E.; Anish Roshi, D.; Salah, Joseph E.; Sault, Robert J.; Srivani, K. S.; Stevens, Jamie B.; Thiagaraj, Prabu; Tingay, Steven J.; Wayth, Randall B.; Waterson, Mark; Webster, Rachel L.; Whitney, Alan R.; Williams, Andrew J.; Williams, Christopher L.; Wyithe, J. Stuart B. (2013)
    In this paper, we explore for the first time the relative magnitudes of three fundamental sources of uncertainty, namely, foreground contamination, thermal noise, and sample variance, in detecting the H I power spectrum ...
