[OIII] emitters in the field of the MRC 0316-257 protocluster
F. Maschietto, N. A. Hatch, B. P. Venemans +12
Venemans et al. (2005) found evidence for an overdensity of Ly-alpha emission line galaxies associated with the radio galaxy MRC 0316-257 at z=3.13 indicating the presence of a mas…
NGC922 - A new drop-through ring galaxy
O. I. Wong, G. R. Meurer, K. Bekki +26
We have found the peculiar galaxy NGC922 to be a new drop-through ring galaxy using multi-wavelength (UV-radio) imaging and spectroscopic observations. Its `C'-shaped morphology an…
The Expansion Asymmetry and Age of the Cassiopeia A Supernova Remnant
R. A. Fesen, M. C. Hammell, J. Morse +7
HST ACS images of the young SN remnant Cas A are used to explore the expansion and spatial distribution of its highest velocity debris. Proper motions of over 1800 outlying ejecta…
Physical Conditions and Star Formation Activity in the Intragroup Medium of Stephan's Quintet
C. K. Xu, N. Lu, J. J. Condon +2
New multi-band observations of the famous compact group of galaxies Stephan's Quintet (SQ) are presented and analyzed. These include far infrared (FIR) images at 60 and 100…
The Dynamical Evolution of Narrow Line Regions
M. A. Dopita, G. V. Bicknell, R. S. Sutherland +1
We review recent progress by the RSAA team in elucidating the dynamical evolution of the various classes of Narrow Line Regions (NLR) in active galaxies.
Observation of Cosmological Time Dilation using Type Ia Supernovae as Clocks
G. Goldhaber, S. Deustua, S. Gabi +23
This work is based on the first results from a systematic search for high redshift Type Ia supernovae. Using filters in the R-band we discovered seven such SNe, with redshift z = 0…
