Radio Frequency Spectra of 388 Bright 74 MHz Sources (2007)
Helmboldt, J. F., Kassim, N. E., Cohen, A. S., Lane, W. M., Lazio, T. J.
As a service to the community, we have compiled radio frequency spectra from the literature for all sources within the VLA Low Frequency Sky Survey (VLSS) that are brighter than 15 Jy at 74 MHz. Over...
Discovery of 35 New Supernova Remnants in the Inner Galaxy (2006)
Brogan, C. L., Gelfand, J. D., Gaensler, B. M., Kassim, N. E., Lazio, T. J.
We report the discovery of up to 35 new supernova remnants (SNRs) from a 42 arcsec resolution 90cm multi-configuration Very Large Array survey of the Galactic plane covering 4.5 deg< l
Ojha, Roopesh, Fey, Alan L., Lazio, T. J., Jauncey, David L., Lovell, James E., Kedziora-Chudczer, Lucyna
Multiwavelength Very Long Baseline Array observations of a sample of 49 extragalactic radio sources selected from the Micro-Arcsecond Scintillation-Induced Variability survey are presented. These...
LaRosa, T. N., Brogan, C. L., Shore, S. N., Lazio, T. J., Kassim, N. E., Nord, M. E.
New low-frequency 74 and 330 MHz observations of the Galactic center (GC) region reveal the presence of a large-scale ($6\arcdeg\times 2\arcdeg$) diffuse source of nonthermal synchrotron emission. A...
Brogan, C. L., Gaensler, B. M., Gelfand, J. D., Lazendic, J. S., Lazio, T. J., Kassim, N. E., ...
We present the discovery of non-thermal radio and X-ray emission positionally coincident with the TeV $\gamma$-ray source HESS J1813--178. We demonstrate that the non-thermal radio emission is due to...
Spatial and Temporal Variations in Small-Scale Galactic HI Structure Toward 3C~138 (2005)
Brogan, C. L., Zauderer, B. A., Lazio, T. J., Goss, W. M., De Pree, C. D., Fasion, M. D.
We present three epochs of VLBA observations of Galactic HI absorption toward the quasar 3C~138 with resolutions of 20 mas (~ 10 AU). This analysis includes VLBA data from observations in 1999 and...
Spatially Resolved Low Frequency VLA observations of the Supernova Remnant 3C 391 (2005)
Brogan, C. L., Lazio, T. J., Kassim, N. E., Dyer, K. K.
We present VLA images of the supernova remnant (SNR) 3C~391 at 74, 330, and 1465 MHz. This remnant has been known for some time to exhibit a turnover in its integrated radio continuum spectrum at...
Brogan, C. L., Devine, K. E., Lazio, T. J., Kassim, N. E., Tam, C. R., Brisken, W. F., ...
We have imaged a 1 deg^2 field centered on the known Galactic supernova remnant (SNR) G11.2-0.3 at 74, 330, and 1465 MHz with the Very Large Array radio telescope (VLA) and 235 MHz with the Giant...
Opening a New Window on the Universe: High-Resolution, Long-Wavelength Radio Astronomy (1998)
Kassim, Namir E., Lazio, T. J., Erickson, William C.
Although Jansky's (1933) discovery of radio astronomy was at decametric wavelengths, the urgent quest for ever higher angular resolution and the fact that ionospheric structure limits interferometric...
Lazio, T. J., Cordes, James M.
The process of assembly of the largest clusters of galaxies, M approx. greater than 10(exp 14) solar mass, should have produced shocks that accelerated electrons to TeV energies. In turn, these...
Lazio, T. J., Cohen, A. S., Crane, P. C., Weiler, K. W.
We consider the impact of potential LOFAR sites on the key astronomical projects set for the telescope. We compare the sites on the basis of the total fraction of the sky accessible and on the basis...
