On the physical nature of accretion disc viscosity
R. G. Martin, C. J. Nixon, J. E. Pringle +1
We use well-established observational evidence to draw conclusions about the fundamental nature of the viscosity in accretion discs. To do this, we first summarise the observationa…
New insights on the Galactic Bulge Initial Mass Function
A. Calamida, K. C. Sahu, S. Casertano +15
We have derived the Galactic bulge initial mass function of the SWEEPS field in the mass range 0.15 1.0, using deep photometry collected with the Advanced Camera f…
First Detection of the White-Dwarf Cooling Sequence of the Galactic Bulge
A. Calamida, K. C. Sahu, J. Anderson +13
We present Hubble Space Telescope data of the low-reddening Sagittarius window in the Galactic bulge. The Sagittarius Window Eclipsing Extrasolar Planet Search field (3'x3'), toget…
The white dwarf cooling sequence of the Galactic bulge
A. Calamida, K. Sahu, J. Anderson +9
We collected F606W- and F814W-band time-series data of the Sagittarius low-reddening window in the Galactic bulge with the Advanced Camera far Surveys mounted on the Hubble Space T…
Evidence for Type Ia Supernova Diversity from Ultraviolet Observations with the Hubble Space Telescope
Xiaofeng Wang, Lifan Wang, Alexei V. Filippenko +93
We present ultraviolet (UV) spectroscopy and photometry of four Type Ia supernovae (SNe 2004dt, 2004ef, 2005M, and 2005cf) obtained with the UV prism of the Advanced Camera for Sur…
Long gamma-ray bursts and core-collapse supernovae have different environments
A. S. Fruchter, A. J. Levan, L. Strolger +30
When massive stars exhaust their fuel they collapse and often produce the extraordinarily bright explosions known as core-collapse supernovae. On occasion, this stellar collapse al…
