WIDGET: System Performance and GRB Prompt Optical Observations
WIDGET System Performance GRB Prompt Optical Observations
font style='font-size:12px;'>
2011/1/10
The WIDeField telescope for Gamma-ray burst Early Timing (WIDGET) is used for a fully automated, ultra-wide-field survey aimed at detecting the prompt optical emission associated with Gamma-ray Bursts...
A search for Star-Planet-Interactions in the upsilon Andromedae system at X-ray and optical wavelengths
Star-Planet-Interactions the upsilon Andromedae system

2011/1/11
Close-in, giant planets are expected to influence their host stars via tidal or magnetic interaction. But are these effects strong enough in suitable targets known so far to be observed with today's i...
An optical/NIR survey of globular clusters in early-type galaxies II. Ages of GC systems and the relation to galaxy morphology
globular clusters early-type galaxies II

2011/1/10
Context: Some photometric studies of extragalactic globular cluster (GC) systems using the optical and near-infrared colour combination have suggested the presence of a large fraction of intermediate-...
UV, optical and near-IR diagnostics of massive stars
UV optical near-IR diagnostics
font style='font-size:12px;'>
2011/1/11
We present an overview of a few spectroscopic diagnostics of massive stars. We explore the following wavelength ranges: UV (1000 to 2000 A), optical (4000--7000 A) and near-infrared (mainly H and K ba...
A photoionization model of the spatial distribution of the optical and mid-IR properties in NGC595

font style='font-size:12px;'>
2011/1/13
We present a set of photoionization models that reproduce simultaneously the observed optical and mid-infrared spatial distribution of the HII region NGC595 in the disk of M33 using the code CLOUDY. B...

Probing Intermediate Mass Black Holes With Optical Emission Lines from Tidally Disrupted White Dwarfs
Probing Intermediate Mass Black Holes Optical Emission Lines
font style='font-size:12px;'>
2011/1/13
We calculate the emission line spectrum produced by the debris released when a white dwarf (WD) is tidally disrupted by an intermediate-mass black hole (IMBH; $M\sim 10^{2}-10^{5}\msun$) and we explor...
Optical multiband surface photometry of a sample of Seyfert galaxies. I. Large-scale morphology and local environment analysis of matched Seyfert and inactive galaxy samples
galaxies Seyfert – galaxies structure – techniques image processing – techniques photometric
font style='font-size:12px;'>
2010/11/12
Context. Parallel analysis of the large-scale morphology and local environment of matched active and control galaxy samples plays an important role in studies of the fueling of active galactic nuclei.
The Laboratory Complex for the Calibration of Photometers Using the Optical Method for Determination of the Water Vapor Content in the Earth Atmosphere
Instrumentation and Methods for Astrophysics (astro-ph.IM)
font style='font-size:12px;'>
2011/1/7
We describe the laboratory complex for the calibration of photometers that are used in weather service to measure the water vapor content in the Earth atmosphere.
Optical Redshift and Richness Estimates for Galaxy Clusters Selected with the Sunyaev-Zel'dovich Effect from 2008 South Pole Telescope Observations

font style='font-size:12px;'>
2010/3/9
We present redshifts and optical richness properties of 21 galaxy clusters uniformly selected by their Sunyaev-Zel'dovich signature. These clusters, plus an additional, unconfirmed candidate, were det...
