Planets in the Galactic Bulge: Results from the SWEEPS Project
Kailash C. Sahu, Stefano Casertano, Jeff Valenti +13
The exoplanets discovered so far have been mostly around relatively nearby and bright stars. As a result, the host stars are mostly (i) in the Galactic disk, (ii) relatively massiv…
The H Luminosity Function and Star Formation Rate at in the Cosmos 2 Square-Degree Field
Y. Shioya, Y. Taniguchi, S. S. Sasaki +25
To derive a new H luminosity function and to understand the clustering properties of star-forming galaxies at , we have made a narrow-band imaging survey for H$α…
The Peculiar Horizontal Branch Morphology of the Galactic Globular Clusters NGC 6388 and NGC 6441: new insights from UV observations
G. Busso, S. Cassisi, G. Piotto +9
In this paper we present multiband optical and UV Hubble Space Telescope photometry of the two Galactic globular clusters NGC 6388 and NGC 6441. We have obtained the first UV color…
New HST Views at Old Stellar Systems
Alvio Renzini
HST has recently revealed that many among the most massive globular clusters harbor multiple stellar populations, and --most surprisingly-- some of them are extremely helium rich.…
Dynamical Properties of z~2 Star Forming Galaxies and a Universal Star Formation Relation
N. Bouche, G. Cresci, R. Davies +17
We present the first comparison of the dynamical properties of different samples of z~1.4-3.4 star forming galaxies from spatially resolved imaging spectroscopy from SINFONI/VLT in…
Distances of the bulge globular clusters Terzan 5, Liller 1, UKS 1 and Terzan 4 based on HST NICMOS photometry
S. Ortolani, B. Barbuy, E. Bica +2
A large number of pulsars and X-rays sources are detected in globular clusters. To understand the structure and content of these clusters, accurate distances are required. We deriv…
