Second-generation microlensing planet surveys: a realistic simulation
surveys – gravitational lensing: micro – methods: statistical – binaries: general – planetary systems – Galaxy: stellar content
2011/10/20
Microlensing surveys, which have discovered about a dozen extrasolar planets to date, have focused on the small minority of high-magnification lensing events, which have a high sensitivity to planet d...
Multi-wavelength extragalactic surveys and the role of MeerKAT and SALT
Multi-wavelength extragalactic surveys role MeerKAT SALT
2011/10/21
In these proceedings I discuss a range of surveys that are currently underway at optical, near-infrared and far-infrared wavelengths that have large components accessible to both the Southern African ...
Catalogs of Hot White Dwarfs in the Milky Way from GALEX's Ultraviolet Sky Surveys. Constraining Stellar Evolution
Astronomical Data Bases catalogues — stars white dwarfs — stars evolution — Galaxy
2010/11/11
We present comprehensive catalogs of hot star candidates in the Milky Way, se-lected from GALEX far-UV (FUV, 1344-1786°A) and near-UV (NUV, 1771-2831°A)imaging. The FUV and NUV photometry allows us to...
Planetary Nebula Surveys: Past, Present and Future
Stars post-AGB – planetary nebulae general – surveys general
2010/11/10
In this review we cover the detection, identification and astrophysical importance of planetary nebulae (PN). The legacy of the historic Perek & Kohoutek and Acker et al. catalogues is briefly covered...
Star formation trends in high-redshift galaxy surveys: the elephant or the tail?
high-redshift galaxy elephan tail
2010/11/15
Star formation rate and accummulated stellar mass are two fundamental physical quantities that describe the evolutionary state of a forming galaxy. Two recent at-tempts to determine the relationship b...
Galaxy clustering and projected density profiles as traced by satellites in photometric surveys: Methodology and luminosity dependence
Galaxy clustering projected density profiles photometric surveys
2010/11/12
We develop a new method which measures the projected density distribution wp(rp)n of photometric galaxies surrounding a set of spectroscopically-identified galaxies, and simultaneously the projected c...
Radio-continuum detections of Galactic Planetary Nebulae I. MASH PNe detected in large-scale radio surveys
Radio-continuum Galactic Planetary Nebulae I
2011/1/10
We present an updated and newly compiled radio-continuum data-base for MASH PNe detected in the extant large scale "blind" radio-continuum surveys (NVSS, SUMSS/MGPS-2 and PMN) and, for a small number ...
