The Optical Gravitational Lensing Experiment. OGLE-III Photometric Maps of the Galactic Bulge Fields
Optical Gravitational Lensing Experiment OGLE-III Photometric Galactic Bulge Fields
2011/10/12
We present OGLE-III Photometric Maps of the Galactic bulge fields observed during the third phase of the OGLE project. This paper describes the last, concluding set of maps based on OGLE-III data.

The Optical Gravitational Lensing Experiment. Analysis of the bulge RR Lyrae population from the OGLE-III data
Optical Gravitational Lensing Experiment Analysis bulge population
2011/10/10
We have analyzed data on 16,838 RR Lyrae variables observed toward the Galactic bulge during the third phase of the Optical Gravitational Lensing Experiment (OGLE) in 2001-2009. Using this type of sta...
The Optical Gravitational Lensing Experiment. Dwarf Novae in the OGLE Data. I. Three New Dwarf Novae: One in the Period Gap and Two Longer Period Objects
novae, cataclysmic variables – binaries: close – surveys
2011/10/8
We report serendipitous discovery of three new dwarf novae which eruptions in 2010 were observed by the ongoing microlensing survey OGLE-IV. All three objects are located in the Galactic bulge fields ...
Mapping gravitational lensing of the CMB using local likelihoods
Mapping gravitational lensing the CMB local likelihoods
2011/1/4
We present a new estimation method for mapping the gravitational lensing potential from observed CMB intensity and polarization fields. Our method uses Bayesian techniques to estimate the average curv...
Gravitational lensing by a regular black hole
gravitational lensing black hole physics regular solutions
2010/12/20
In this paper, we study a regular Bardeen black hole as a gravitational lens. We find the strong deflection limit for the deflection angle, from which we obtain the positions and
magnifications of th...
In recent years, there has been increasing recognition of the potential of the galactic center as a probe of general relativity in the strong field. There is almost certainly a black hole at Sgr A* in...
Effects of Strong Gravitational Lensing on mm-wave Galaxy Number Counts
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/24
We study the effects of strong lensing on the observed number counts of mm sources using a ray tracing simulation and two number count models of unlensed sources.
Strong gravitational lensing across dilaton anti-de Sitter black hole
anti de Sitter gravitational lensing black holes
2010/3/18
In this work we investigate gravitational lensing effect in strong field region around a dilaton black holes in an anti de Sitter (ADS) space. We also analyse the dependence of the radius of the photo...

Light on Dark Matter: Gravitational Lensing by Galaxy Clusters
Dark Matter Gravitational Lensing Galaxy Clusters
2010/10/18
I discuss the use the weak gravitational lensing effect to study the mass distribution and dynamical state of a sample of 24 X-ray luminous clusters of galaxies. By comparing the mass and light distri...
