The properties of powerful radio sources at 90 GHz
M. J. Hardcastle, L. W. Looney
We have observed a small sample of powerful double radio sources (radio galaxies and quasars) at frequencies around 90 GHz with the BIMA millimetre array, with the intention of con…
Constraining the Earliest Circumstellar Disks and their Envelopes
Hsin-Fang Chiang, Leslie W. Looney, Konstantinos Tassis +2
Using interferometric data from BIMA observations, combined with detailed modeling in Fourier space of the physical structures predicted by models, we constrain the circumstellar e…
The X-Ray Origin of Herbig AeBe Systems: New Insights
Murad Hamidouche, Shiya Wang, Leslie W. Looney
We present a statistical study of the X-Ray emission toward 22 Herbig AeBe stars using the Chandra archive. We probe the origin of the X-Rays toward Herbig stars: are they intrinsi…
Morphological Evolution of Outflows from YSOs
Jonathan P. Seale, Leslie W. Looney
We present Spitzer IRAC images that indicate the presence of cavities cut into the dense outer envelope surrounding very young pre-main sequence stars. These young stellar objects…
A Flattened Protostellar Envelope in Absorption around L1157
Leslie Looney, John Tobin, Woojin Kwon
Deep Spitzer IRAC images of L1157 reveal many of the details of the outflow and the circumstellar environment of this Class 0 protostar. In IRAC band 4, 8 microns, there is a flatt…
Dense Molecular Gas In A Young Cluster Around MWC 1080 -- Rule Of The Massive Star
Shiya Wang, Leslie W. Looney, Wolfgang Brandner +1
We present CS , CO , and CO , observations with the 10-element Berkeley Illinois Maryland Association (BIMA) Array toward the y…
