Exposing metal and silicate charges to electrical discharges: Did chondrules form by nebular lightning?
C. Güttler, T. Poppe, J. T. Wasson +1
In order to investigate the hypothesis that dust aggregates were transformed to meteoritic chondrules by nebular lightning, we exposed silicatic and metallic dust samples to electr…
An observation of a mutual event between two satellites of Uranus
M. G. Hidas, A. A. Christou, T. M. Brown
We present observations of the occultation of Umbriel by Oberon on 4 May, 2007. We believe this is the first observed mutual event between satellites of Uranus. Fitting a simple ge…
Can gravitational infall energy lead to the observed velocity dispersion in DLAs?
Alexei O. Razoumov, Michael L. Norman, Jason X. Prochaska +3
The median observed velocity width v_90 of low-ionization species in damped Ly-alpha systems is close to 90 km/s, with approximately 10% of all systems showing v_90 > 210 km/s at z…
Large amounts of optically-obscured star formation in the host galaxies of some type-2 quasars
M. Lacy, A. Sajina, A. O. Petric +5
We present Hubble Space Telescope images, and spectral energy distributions from optical to infrared wavelengths for a sample of six 0.3<z<0.8 type-2 quasars selected in the mid-in…
SNLS Spectroscopy: Testing for Evolution in Type Ia Supernovae
T. J. Bronder, I. M. Hook, P. Astier +19
Aims: We present a quantitative study of a new data set of high redshift Type Ia supernovae spectra, observed at the Gemini telescopes during the first 34 months of the Supernova L…
X-ray Group and cluster mass profiles in MOND: Unexplained mass on the group scale
Garry W. Angus, Benoit Famaey, David A. Buote
Although very successful in explaining the observed conspiracy between the baryonic distribution and the gravitational field in spiral galaxies without resorting to dark matter (DM…
